Finally, I would like to thank all of my participants for taking time out of their busy schedules to perform within my two testing sessions. i Tanya Chick –ST08003621 ABSTRACT Objective: To investigate if a single massage of the hamstring, quadriceps and calf muscle groups would alter the performance of a speed and endurance shuttle run test and an on court agility test. Methods: Nine Female Club level badminton players volunteered to participate in a controlled crossover, experimental design study. The participants were involved in two testing sessions which were exactly a week apart. One session was performed with a pre event sports massage prior to testing and the other session was executed in the same manner but without massage. The treatment consisted of a fifteen minute massage to each of the lower limbs, five minutes quadriceps, five minutes hamstrings and five minutes to calves. The participants then completed three testing protocols which consisted of; a speed shuttle run x 3, an endurance shuttle run x8 and an on court agility test x 3. A SPSS paired T test was then adopted to analyse whether there was a significant affect from the pre event sports massage with regards to the three testing protocols. Data displayed as mean ± SD, N=9, significance accepted at p<0.05. Results: No significant affect was found in any of the three testing protocols. Speed, endurance and agility all demonstrated results that suggested that p>0.05 and therefore a significant difference was not detected. Conclusion: These findings suggest that a single pre event sports massage to the lower limbs of female badminton players has no significant affect with regards to enhancing performance within the fields of speed, endurance and agility. It has been detected that the use of pre event sports massage potentially develops psychological benefits with regards to mental readiness and stimulation even though physiological benefits have currently been rejected. ii Tanya Chick –ST08003621 CHAPTER ONE INTRODUCTION Tanya Chick –ST08003621 1.0 Introduction 1.1 Overview of Badminton The main purpose of this study is to identify the effects of pre event sports massage on the lower limbs of female badminton players. Speed, endurance and agility whilst on court, will be the protocols that are analysed and tested throughout the study. Badminton is identified as being a very physically and psychologically demanding game, (Kuntze et al, 2010) .It requires a vast amount of high impact movement patterns during an on court rally which can often cause a great amount of muscular fatigue within the lower limbs, (Golds, 2002). Bloss and Hales (2001) discovered that agility and speed are the two vital components that are required to be a successful badminton player. If a player does not excel within these two areas, other disciplines within their game will start to deteriorate, such as; shot technique and the ability to make decisions on what shots to play during a game. Badminton is an understated sport and is not widely recognised throughout the world as being a top class sport, such as rugby or football; this was identified by Lin et al (2007). Cabello et al (2004) discovered that this is partly because the sport is very rarely broadcasted on the television and is not highly promoted during world class or even local events. These issues highlight why action needs to be taken towards the sport of badminton and hopefully by carrying out this study it will enable the players and coaches to find a way to move their game forward in a positive direction. 1.2 Overview of Massage Many sports clubs around the world use the methods of sports massage to aid towards maintaining and enhancing the performance of their players, which was noted by Paine (2000). Paine (2000) also recognised that benefits from pre event sports massage are believed to include: Increase of the supply of nutrients and oxygen to the muscles, which would not only stimulate the athlete physically but mentally too. Warming of connective tissue. Stretching for optimal range and flexibility. 1 Tanya Chick –ST08003621 Improving the flexibility of a badminton player could enable them to have the extra edge that they require to reach the shuttle or to take that extra little step to position themselves under the shuttle to play the ultimate shot during that point of play. This was realised by Bloss and Hales (2001). The requirements of pre event sports massage are identified as being; rapid, superficial, less relaxing and to last for a short duration of time (e.g. 15 minutes). This type of massage is always used before an athlete is due to participate in their sporting event, to enable them to get mentally and physically prepared for their performance, which was discovered by Benjamin and Lamp (2005). With everything we know about the high impact movements executed when playing badminton on court along with the effects that pre event sports massage can have on athletes, there is a clear justification of why this study could be extremely beneficial to all badminton players and coaches. 1.3 Research Problem There have been many investigations carried out on the two separate disciplines of pre event sports massage and badminton but none that have been investigated with both disciplines together. Therefore, this study will be the first insight into whether pre event sports massage can affect the lower limbs of female badminton players. Previous research can aid towards finding out what gaps in the literature there are within this area along with looking at the advantages and disadvantages of what research has been previously found within other sports and to gage an idea of which testing methods and actual tests executed that have been beneficial and effective. This will aid justification for tests and testing methods used within this research project. The study will analyse the demands of badminton and how pre event sports massage could potentially affect specific aspects of the game, such as speed, endurance and agility. 1.4 Null Hypothesis The following hypothesis has been made suggested for this study: Pre event sports massage does not have any significant affect on the lower limbs of female badminton players, in relation to performance within the fields of speed, endurance and agility. 2 Tanya Chick –ST08003621 CHAPTER TWO LITERATURE REVIEW Tanya Chick –ST08003621 2.0 Literature Review 2.1 Massage and Badminton Analysis The three main physiological demands required to excel within badminton consist of; speed, endurance and agility. Cabello (2004) recognised that on average a standard ladies singles game lasted for duration of thirty two minutes and fifty two seconds with a total work time of nine minutes and four seconds. It was also recognised that as level of competition and standard of play increased, games were recorded to go on for as long as fifty five minutes with a total work time of twenty five minutes. Due to these results it can be identified that badminton players need to have a significant level of endurance to withstand and average rally/badminton match. This however directly leads in with speed and agility due to the fact that the higher endurance levels that the athlete has their ability to manoeuvre themselves around the court efficiently and at speed will begin to become effortless, which was recognised by Lin et al (2007). Many theories have been proposed with regards to whether sports massage has a positive affect when being used in a performance context. There is a wide selection of literature within the field of massage, pre event and post, which aim to prove whether it should be a key factor with regards to sporting performance. Sports massage and badminton are vast subjects which currently have a large amount of literature surrounding them, however this study will focus on three main disciplines when reviewing the literature, and these are identified as; The effects of pre event sports massage on the lower limbs in reference to performance The effects of pre and post sports massage on any limb in reference to performance The physiological and biomechanical analysis in Badminton. This study will particularly focus on the pre event sports massage aspect on the lower limbs when incorporated within sports performance in badminton. 3 Tanya Chick –ST08003621 Paine (2000) identified Sports massage as being a form of massage that involves manipulating the soft tissue to benefit a person that has been injured, repetitively completing tasks or with tension in general. Findlay (2010) noted that there are several different techniques that are executed when performing sports massage, these include; Effleurage Petrissage Tapotement Frictions Compressions. Many of these techniques are often used in the hope to benefit badminton players with their performance. 4 Tanya Chick –ST08003621 Table 1. Table summarizing studies related to physiological and biomechanical analysis in Badminton. Study Study Design Participants Techniques Used A Biomechanical Analysis of Common Lunge Tasks in Badminton – Kuntze et al (2010) Controlled & Crossover Experimental Video Pilot based study Nine male first and second team players from the student badminton squad A video based analysis was used to watch national and international competitions to assess lunge frequency Bilateral Ground Reaction Forces and Joint Moments for Lateral Side Stepping and Crossover Stepping Tasks – Kuntze et al (2009) Controlled and Experimental Nine male student badminton players from the 1st or 2nd team and play at least 6 hours of badminton per week. Kinematics of the lower limbs was recorded using force plates. Heart Rate and Blood Lactate Responses during Execution of some Sport Specific Strokes in Badminton Drills – Ghosh (2008) Controlled ,Experimental , Crossover Eight National level players from India with an experience of 6-7 years at national level. VO2 Max testing on bicycle ergometers and on-court agility and hitting techniques at high intensity. 5 Treatment Time/Rest Periods Five minute w/u oncourt lunge task was set up where athletes had to complete three different lunge movements, where upon force was then analysed. 3 movement tasks were executed, which involved; a straight line run, lateral sidestepping and crossover stepping. 10 repeats were performed at a controlled speed. Results and Conclusions VO2max was taken at every 15 second interval and weight was increased by 0.5 w/kg every 2 mins until exhaustion and the oncourt tests were 3 sets, each set consisted of 10 reps of 15 secs activity with 30 secs rest. H/R and blood lactate responses were high during movements on court. Repeating the shots executed will increase aerobic and anaerobic capacities due to exerted cardiovascular and metabolic stress. The step lunge could reduce muscular demands of lunge recovery and the hop lunge could allow for higher positive power output and enabling an efficient lunging method. With side stepping and crossovers the ground reaction forces we mainly lower and lacked a vertical peak impact which could indicate that overuse injuries become less of a risk compared to straight running. Tanya Chick –ST08003621 Specific Inspiratory muscle warm-up enhances badminton footwork performance – Lin et al (2007) Controlled and Experimental Ten male badminton players who play regular badminton were recruited. Temporal and Physiological characteristics of elite women’s and men’s singles badminton – Cabello et al (2004) Temporal structure and a descriptive study 79 male and female badminton players who have participated at national, international and world level competitions. Participants had to perform identical IM function tests and maximal incremental badminton footwork tests in 3 conditions at random. The warm ups were badminton specific. Before the experimental trials, lung function, maximum Inspiratory mouth pressure and aerobic capacity were assessed. Data was collected on actions in play, which were video recorded and analysed retrospectively for all matches, heart rates and blood lactate concentration from capillary samples taken from the earlobe. 6 3 conditions were chosen; control, placebo and experimental. Control did not involve IM warm up, whereas the experimental and placebo did. Consisted of 2 sets of 30 min breath manoeuvres with an Inspiratory pressure threshold load equivalent to 15% and 40% max Inspiratory mouth pressure. The investigator s attended every single competition and recorded all the matches. Lactate was tested by using BMlactate reactive strips, at 1st, 3rd, 5th and 10th min of the recovery. H/R was recorded every 5 secs throughout the matches via telemetry pulsometer. The IM specific warm up suggested that footwork was improved during the testing, this was possibly due to the reduced breathlessness sensation, which was a result of the enhanced IM function. Significant differences existed between men’s and women’s sectors at all levels of competition except for the world championships and in between levels of elite competition. This has recommended that training should be tailored around short but intense sessions to develop the alactic aerobic system and to lessen the lactic anaerobic system. Tanya Chick –ST08003621 2.2 Review of Physiological and Biomechanical Aspects of Badminton Badminton is recognised as being a fast paced and agile game. Vital components for success within this sport are speed, agility, flexibility and the ability to make a rapid decision of which shot to execute during a rally, (Golds 2002). There has been a vast amount of previous research with regards to physiological and biomechanical analysis within badminton, a sample of these studies have been demonstrated within table 1. 2.2.1 Assessment of Sample Sizes Adopted From Table 1, it can be seen that most of the previous researchers used between eight and ten participants as a sample size when executing their testing sessions, this is in contrast to Cabello et al (2004) who collated a group of seventy nine volunteers. Cabello et al (2004) justified using a larger sample size such as this due to the fact that their project was performed as a descriptive study with the aim to discover the differences of temporal and physiological characteristics between elite men’s and women’s single badminton. This is opposed to all of the other research projects in table 1, as they used physical performance testing methods to gain their results. 2.2.2 Assessment of Study Design Adopted All tests performed were mainly carried out using controlled, crossover and experimental designs which directly relates to the research project mentioned within this dissertation and could therefore suggest that using the smaller sample size of between eight and ten and using the same research designs could benefit this project by making it as valid and relative to current research as possible. O’Donoghue (2010) identified that experimental research consists of a designated number of participants partaking in set activities under controlled conditions which are related to the purpose of investigating the effect of the experimental hypothesised dependant variables. The more substantial results were also found from the controlled and experimental research projects. Lin et al (2007) realised from their results that Inspiratory muscular specific warm ups could suggest that footwork was improved during testing which could be beneficial for players or coaches in the future as they could incorporate these specific warm ups into their training sessions to gain the best performance from the player. As this research project consists of executing controlled tests with the participants with the goal to find a hypothesised result, the experimental design would be the best method to 7 Tanya Chick –ST08003621 adopt and with the previous researchers having used this method successfully would be another reason for this project to be carried out in the experimental manner. It is hypothesised throughout this research project that the there will be a significant effect to the lower limbs of female badminton players with regards to speed, endurance and agility. To find whether this hypothesis is correct, a set of badminton specific on court tests will be executed in a controlled environment. 2.2.3 Assessment of Data Collection Kuntze et al (2010) and Cabello et al (2004) both used video analysis to determine technique performance and physiological characteristics between male and female badminton players, this is in contrast to Ghosh (2008), Kuntze et al (2009), and Lin et al (2007) who all used specialist equipment such as force plates, bicycle ergometers and Inspiratory equipment. When executing the tests within these projects, they were all very much controlled and structured to what the researcher had hypothesised and specific to the investigation, unlike Kuntze et al (2010) and Cabello et al (2004) who were just analysing what the players would naturally execute and how they would compete during play, which is far more broader than being related to a specific question. Kuntze et al (2009) investigated the forces within the lower limbs in badminton when executing a straight line run, lateral sidestepping and crossover stepping at a controlled speed. This is very similar to the research that will be carried out within this project however Kuntze et al (2009) controlled the speed of the testing and was therefore gauging the forces produced from the players in contrast to this research which is finding out whether the speed is increased on court after a sports massage is executed. Considering the research title is very specific in relation to the effects of pre event sports massage on the lower limbs of female badminton players, the research would benefit from using the same methods as the performance testing projects. 8 Tanya Chick –ST08003621 Table 2: Table summarizing studies related to pre events sports massage on the lower limbs in reference to performance. Study Study Design Participants Techniques Used Effect of massage of the hamstring muscle group on performance of the sit and reach test – barlow et al (2002) Experimental and controlled 11 healthy active males with a history of no musculoskeletal disorders. Acute effects of preevent lower limb massage on explosive and high speed motor capacities and flexibility – Arabaci (2008) Counterbalan ced crossover design 24 physically active healthy Caucasian male subjects. All participants were from a physical education and sport department in a University in Turkey. Effleurage and Petrissage strokes delivered to the hamstring muscle groups on each leg. 2 test sessions were taken, exactly a week apart. One session with massage and one without. Effleurage, friction, Petrissage, vibration and Tapotement was applied on the posterior lower limbs for 10mins and on the anterior lower limbs for 5 mins. Swedish massage was applied. Effect of preperformance lower-limb massage on thirty meter sprint running – Goodwin et al (2007) Experimental counterbalan ced crossover design 37 men who regularly participated in multiple sprint sports for a minimum of 5 hours per week, and general strength training of a minimum of 2 hours per week. Each muscle group had 2.5 mins of massage, which consisted of; 1 minute of effleurage, 45 seconds of Petrissage and 45 seconds of Tapotement. Tapotement was divided into; 15 secs of: cupping, hacking and knuckling. 9 Treatment Time/Rest Periods Three sit and reach attempts were executed with 30 seconds rest between each attempt. During the massage session, the massage lasted for 15 mins over both of the hamstrings. The experiment had 3 conditions; massage, stretching and rest. Which was conducted pre and post of doing the 10metre acceleration, flying start 20m sprint, 30 metre sprint from standing, leg reaction time, vertical jump and sit and reach tests. Three 30 meter sprint trials were completed, with a 5 min recovery. Times were measured using twin beam infrared cells and were placed at 0, 10 and 30 metres. 3 conditions were present: massage, placebo ultrasound, and rest. Results and Conclusions A single massage of the hamstring muscle group did not have any significant difference/increase when performing the sit and reach test. The current findings suggested that a 10min massage on the posterior lower limbs and a 5 min massage on the anterior lower limbs had an adverse effect on vertical jump, speed and reaction time and also a positive effect on the sit and reach test results. Results showed that when incorporating a pre event massage, there was no effect on 30 metre sprinting performance. Tanya Chick –ST08003621 Dynamic soft tissue Controlled mobilisation single blind increases hamstring design flexibility in healthy male subjects – Hopper et al (2005) 45 healthy male volunteers between ages of 18-35. They must not have had a hamstring injury within a previous 2 years or lower back in 2 months. Acute effects of two massage techniques on ankle joint flexibility and power of the plantar flexors – McKechnie et al (2007) Controlled, experimental, crossover design Nineteen male and female students from the University of Ballarat. Who was all injury free in the ankles, lower legs. Effects of Petrissage Massage on Fatigue and Exercise Performance following intensive cycle pedalling – Ogai et al (2007) Controlled and experimental Eleven female students, from Chukyo University School of health and sports sciences, actively engaged in sports, of a minimum of 3 days per week in the university’s sports programme. Swedish traditional massage: Effleurage, kneading, picking up and shaking. 5 strokes per technique, completed in 5 mins. Specific tension within the hamstrings was also targeted, whilst the hamstring was loaded actively, passively and eccentrically, as part of a dynamic Swedish massage. Petrissage to the plantar flexors for 3 mins on each leg. Tapotement; Hacking was applied to plantar flexors also for 3 mins on each leg. Petrissage was applied for 10 mins from 5th to the 15th minute of resting period. For each muscle in the lower limbs, 12 compressions were executed within 1 min, from distal to proximal. 10 There were 3 conditions used During this experiment which involved; traditional Swedish massage, dynamic Swedish massage and no intervention. The testing consisted of completing a straight leg raise in each of the conditions. Dynamic soft tissue mobilisation significantly increased hamstring flexibility in healthy male subjects. 3 conditions were used; control (no massage), Petrissage and Tapotement. After each condition the participants performed 2 power tests and a post ankle flexibility test. The experiment had 2 control groups: with and without Petrissage. The participants had to do the ergometer tests twice, roughly on the same day a week apart. 2 sets of trials were done on the ergometers with 35 mins resting periods. Testing showed a significant increase in ankle joint angle on both legs. No significant change was seen with the power measures. Petrissage improved cycle ergometer pedalling performance independent of blood lactate but in correlation with improved recovery from muscle stiffness and perceived lower limb fatigue. Tanya Chick –ST08003621 Effects of Massage on physiological restoration, perceived recovery and repeated sports performance – Hemmings et al (2000) Controlled and counterBalanced. Eight male amateur boxers, who have all participated in the sport for a minimum period of 2 years. Massage in a 20 min routine. Major muscle groups in legs (8mins), back (2 mins) and shoulders and arms (10 mins). Effleurage and Petrissage used. 11 2 conditions were used; with and without massage. A boxing ergometer was used for both conditions. Blood lactate, glucose levels and heart rates were also monitored pre, during and post trials. No significant results were found to prove that massage can improve boxing performance. However, a decrease in punching force was found after the massage condition. Tanya Chick –ST08003621 2.3 Review of Studies that Analyse the Effects of Pre Event Sports Massage on the Lower Limbs of Athletes in Reference to Performance Sports Massage is defined by Norris (1998) as a deep form of tissue work that is applied in a sporting context. It consists of a variety of techniques; effleurage, Petrissage, Tapotement, vibrations, compressions, and frictions. The main focus of sports massage is to help the athlete achieve peak performance and remain injury free as well as to support the healing of injuries. (Findlay 2010). There are three different methods of massage and these are recognised by Paine (2000) as Pre, Inter and Post Event Massage, these have all been defined below: Pre – The aim to stimulate skin, sensory receptors and circulation within the muscles treated. It is often superficial and fast paced and due to this the athlete often becomes psychologically prepared and more competitive with regards to competition/participation. Inter – The aim is to flush away waste products within the muscles being treated and to refresh them with healthy nutrients and to promote an increase in circulation to ensure larger supplies of oxygen are reaching the required muscles in order to continue with optimal performance. The techniques used are often superficial and fast tempo. Post – The aim is aid muscular recovery in order to regain its pre event state for future training/competition. It is also executed to restore; muscle tone, muscle length and flexibility. This is usually performed using deep and slow techniques to also cause a relaxation and regeneration effect. Pre event massage has become the main analysis of this study due to the fact that the massage is being performed prior to the participants executing the required tests. Many researchers have found a correlation between sports massage and the effects on physical performance. 2.3.1 Practical Implications of Massage From table 2, it can be noted that Arabaci (2008), Hopper et al (2005), Mckechnie et al (2007) and Ogai et al (2007) all discovered that sports massage can be related to performance, whether it was beneficial or detrimental in regards to a sporting context. 12 Tanya Chick –ST08003621 Results such as these, could seriously aid a team or athlete due to the fact the coaches will be able to either enter pre event sports massage into a training regime to improve performance or to ensure that it is definitely not in place as part of a warm up if the results show that this will decrease the athletes physical performance. However, in contrast to the above researchers that found a relationship with massage and performance, Barlow et al (2002) and Goodwin et al (2007) found that their results showed no significance with regards to massage effecting sporting performance. This research has proven that there is no consistent correlation with regards to whether sports massage should be incorporated to aid sporting performance and there has also not been any specific research to date that has incorporated the effects of the lower limbs in female badminton players prior to a pre event sports massage. This has therefore shown a gap in the research; hence why the question in this project has been created with the goal to find if a significant effect can be recorded with regards to pre event sports massage and performance, results gained could potentially improve the performance of a player by making a pre event sports massage an addition into their training/competing regime. The designs and sample sizes used in the projects could have also contributed significantly towards the results of the research executed. 2.3.2 Assessment of Sample Sizes Adopted From table 2, it can be seen that the sample sizes used are randomized and there is no set trend as to why smaller or larger sample sizes have been used, these have ranged from eight to forty five and all of the results were collected with a quantitative approach. Barlow et al (2002), Mckechnie et al (2007), Ogai et al (2007) and Hemmings et al (2000) all maintained a sample size under twenty in contrast to Arabaci (2008), Goodwin et al (2007) and Hopper et al (2005) who all ranged from twenty four to forty five participants. From previous research projects that have been identified in figure 1, it can be seen that the majority of the controlled experimental projects by Kuntze et al (2010), Kuntze et al (2009), Ghosh (2008) and Lin et al (2007) chose to adopt sample sizes under ten. This is similar within the research projects within table 2; the controlled and experimental designs executed by Barlow et al (2002) and Ogai et al (2007) both chose to use smaller sample sizes of eleven. This could have been because previous literature had adopted 13 Tanya Chick –ST08003621 similar techniques and achieved significant results or due to the fact that the study was limited with regards to how many participants they were able to recruit. These two projects both received different results but both were effective and valid with the participants that they had recruited. 2.3.3 Assessment of Massage Protocols and Techniques Barlow et al (2002) found that a single massage of the hamstring muscle group did not have a significant effect when performing the sit and reach test, whereas Ogai et al (2007) discovered that Petrissage improved cycle ergometer pedalling performance independent of blood lactate but in correlation with improved recovery from muscle stiffness and perceived lower limb fatigue. Sports Massage is an area that has been researched for many years with the aim to justify its execution in benefiting athletes when performed within a sporting context. Another effecting factor on previous research projects results would consist of which massage techniques were adopted and in which depth and tempo they were performed when testing protocols were executed. Findlay (2010) identified that pre and inter event massage could be beneficial with regards to sporting performance due to the fact that there is an increase in circulation, metabolic rate, sensory receptors and muscular readiness. With these physiological effects in mind, Weerapong et al (2005) suggested that the athlete would be gaining a larger supply of oxygen to the muscles and therefore enabling them to work for longer and in an efficient manner. Weerapong et al (2005) also noted that the athlete would feel a sense of self readiness and competitiveness due to the effects on the sensory receptors within the body which could enable the athlete to be more confident and focused. Paine (2000) suggested that this could all be achieved by executing pre event sports massage hand skills such as; Effleurage – Rotary, V, Cam and Spindle, Forearm Glide and Flat Hand Petrissage Tapotement – Hacking, Cupping and Flicking 14 Tanya Chick –ST08003621 Table 3: Table summarizing studies related to pre and post massage in reference to performance.

Effect of Lower Limb Massage on Electromyography and Force Production of the Knee Extensors – Hunter et al (2005) Experimental, Controlled, Crossover Design 10 Healthy Male Subjects who were physically active on a regular basis volunteered to participate. Sports Massage was performed on a randomly designated leg and repeated cycles of Petrissage and effleurage. 75 secs of Petrissage followed by 75 secs of effleurage, which was repeated for 5 mins. Massage was applied for 30mins in 7mins 30 secs segments to the back of the leg and on the front as well. Effleurage was the technique executed. 15 Treatment time/Rest Period 2 conditions were used; with massage and rest. The group was then separated into 6 groups, where they would then do 30mins of continuous exercise and then the next week would just be rest for 30mins. Questionnaires were taken before and after. Results and Conclusion The results showed that when the participants had received massage or were in the running groups, their moods and psychological states were consistently positively related.

Manual Massage, which consisted of; 30secs of Effleurage, 50secs of Petrissage, superficial warming frictions for 10secs and Tapotement for 30secs. 16 3 maximum concentric and eccentric efforts of knee extensors were performed. After a 3 min break the programme restarted. Each did 6 sets of 10 reps each with 2 mins rest. During rest, massage was given to the knee extensors. After 6th set, another 3 maximum concentric and eccentric efforts were performed. Application of manual massage during the Isokinetic exercise intervals had an enhancing effect on the peak eccentric torque of the knee extensors. Tanya Chick –ST08003621 2.4 Review of Studies Related to Pre and Post Event Massage in Reference to Performance From analysing table 3, it can be seen that there is plenty of literature that have incorporated a form of sports massage into their research, whether it is applied during pre, inter or post event. All projects executed by Hunter et al (2005), Sykaras et al (2003) and Hart et al (2005), adopted an inter event sports massage, which mainly delivered effleurage and Petrissage during their testing protocols. However, all of the research projects analysed in table 2 have adopted the pre event sports massage technique before performing their testing protocols in the aim to find whether this benefits sporting performance. From table 2, it can be seen that Barlow et al (2002) focused entirely on trying to find out whether pre event sports massage helped to increase the distance performed during a sit and reach test and Arabaci (2008) also incorporated a similar protocol with the aim to find an increase during a vertical jump and sit and reach test. However, they both adopted different techniques in which they executed their pre event sports massage; with changes in duration, techniques executed and the limbs in which received the massage. 2.4.1 Assessment of Massage Durations Adopted Barlow et al (2002) decided to execute effleurage and Petrissage strokes to both hamstring muscle groups within a fifteen minute duration, seven and half minutes on each hamstring whereas Arabaci (2008) chose to deliver effleurage, Petrissage, frictions, vibrations and Tapotement to both posterior lower limb muscle groups for ten minutes (five minutes each leg) and to both anterior lower limb muscle groups for five minutes (two and half minutes each leg). Similarly, to Barlow et al (2002), Hemmings et al (2000) also adopted to execute the techniques of effleurage and Petrissage within their pre event sports massage prior to testing, however they also decided to increase the massage duration to twenty minutes in contrast to the fifteen minutes previously identified. The massage duration for both of the projects were set at fifteen minutes each, however the difference is that Barlow et al (2002) only delivered massage to the hamstring muscle group 17 Tanya Chick –ST08003621 unlike Arabaci (2008) who delivered the same duration to anterior and posterior lower limb muscle groups. This study could possibly be hindered with regards to the inconsistence of the massage protocols adopted within each previous study. It has therefore made it harder to adopt a specific protocol that has been practiced throughout previous studies but as a result of this the most consistent durations, techniques and depths/tempos have been recruited for this study. 2.4.2 Assessment of Massage Techniques Adopted in Relation to Performance Arabaci (2008) incorporated sprint testing into their project which included; acceleration, flying and from standing. This would explain why the researcher decided to massage the whole of the lower limbs instead of just the hamstrings as the participants would be using all muscle groups whilst performing the tests required. The testing protocols adopted within Arabaci (2008) study are similar to the testing protocols recruited within this study due to the fact that there are a number of acceleration and speed tests involved, hence why this project has adopted to perform massage on the anterior and posterior lower limb muscle groups to ensure that all muscles are treated evenly before executing the designated tests. The results gained from both of the sit and reach test projects were drastically different, as Barlow et al (2002) discovered that a single massage of the hamstring group did not have any significant difference/increase when performing the sit and reach test, this is in contrast to Arabaci (2008) who suggested that a fifteen minute massage had an adverse effect on vertical jump, speed and reaction time but also had a positive effect on the sit and reach test results. There could have been several different reasons as to why both results were significantly different but the main cause identified is within the techniques performed during the pre event sports massage. 2.4.3 Assessment of Massage Techniques Adopted Effleurage is recognised as being a deep/superficial stroking technique that should always be in the direction of venous or lymph flow. It is often used at the beginning and the end of a massage as it is the gentlest technique, which was identified by Callaghan (1993). 18 Tanya Chick –ST08003621 Hollis (2009) discovered that effleurage can be used throughout any phase of sports massage, whether its pre, inter or post event. However, the depth and tempo of the strokes change accordingly to when the massage is applied. If it was pre/inter event it would be high tempo and superficial unlike if it was post event then it would be slow tempo and deeper strokes. Weerapong et al (2005) identified that slower and deeper strokes would not be used in reference with pre/inter massage due to the fact that not only is it very relaxing and would decrease the motivation or readiness of the player/athlete, but it could also affect certain muscle fibres within the limbs. If techniques are too deep or for too long prior to performance, type I muscle fibres could potentially be turned into type II muscle fibres or vice versa. If this occurred the athlete/player could see a decrease in performance within certain aspects of their game, dependant on which muscle types are required for the competition/event. Petrissage also falls under the same category as effleurage as it promotes the same physiological effects and is often used at any stage during an event with regards to massage. It is identified by Findlay (2010) as being a deep or superficial technique that involves using strokes such as; kneading, skin rolling, lifting, squeezing and stripping. This technique is use to relax, stimulate or separate muscle tissues depending on what phase of the event it is applied during. Tapotement is performed with the aim to stimulate local circulation, muscle tone, tendon reflexes and nerve endings before the athlete/competitor goes onto compete, which was recognised by Hollis (2009). Frictions are defined as a technique that involves cross fibre rubbing over a muscle, tendon or ligament. The strokes are usually applied in the same direction and are usually executed using the thumb, fingers or knuckles. (Copyright SPS ltd 2003). This technique is widely recognised during post event/recovery sports massage as it is often used as a last resort as part of rehabilitation to remodel scar tissue and collagen. It is not often in pre event sports massage, due to this, this project has rejected using the idea of frictions before the participants execute the necessary tests, which was recognised by Copyright SPS ltd (2003). However, in contrast to this, Tapotement is often used within pre event sports massage as it is not only identified for stimulating the body but is also associated with being a beneficial psychological factor for the athlete, as it gets them mentally motivated and in a positive state 19 Tanya Chick –ST08003621 of mind. Tapotement is broken up into a specific set of techniques which are recognised as; hacking, cupping and flicking which was noted by Copyright SPS ltd (2003). 2.4.4 Absence of Consistent Literature Goodwin et al (2007) and Mckechnie et al (2007) also benefited from using Tapotement within their testing protocols when also being accompanied with Petrissage and effleurage. Both of these researchers discovered completely different results as Goodwin et al (2007) identified that there was no significant results shown when incorporating a pre event sports massage with thirty metre sprint tests whereas Mckechnie et al (2007) found that testing showed a significant increase in ankle joint angle on both legs but no significant change was seen with the power measures. This has proven that there is no set trend or pattern that relates to whether pre event sports massage can be a beneficial modality to increase sports performance. Due to this insignificance in the literature, this is another reason that has supported the need for this research question to be executed and especially as, previously mentioned, that there has been no definitive research into the sport of badminton with this concern in mind. 2.5 Overview of Literature Analysed and the Effects it has had on this Study From all of the previous literature that has been reviewed from table 2, it can be identified that the most beneficial and reliable results that were achieved, often came from projects that had adopted a fifteen minute duration for their pre event sports massage and they also applied massage to the anterior and posterior lower limb muscles groups to ensure both legs were completely stimulated and that the blood was circulating around the muscle tissue and that the muscle fibres and tissue were warm and ready to compete/perform directly after the massage had been administered. None of the previous projects that were analysed actually mentioned about the tempo or the depth in which they were executing the massage which makes it difficult to standardise and compare with regards to previous literature, but as previously mentioned, pre event sports massage is recognised as being very fast paced and superficial. Therefore the masseuse that will be delivering the massage throughout this project would also follow along with these guidelines and aim to execute a designated amount of fast paced strokes for each technique within the designated time and in reference to the time 20 Tanya Chick –ST08003621 given to deliver massage to each limb. The masseuse would also remain the same person without the whole project to ensure that they would be using the same pressure and speed throughout each massage that is delivered prior to testing. This would remove the cause of inter-practitioner variability, which was identified by Weerapong et al (2005). This has given this research project enough support and validity to enable this to also adopt the same procedures with the aim to find significant results within this designated field. 2.6 Justification of Research Question From all of the literature that has been reviewed throughout the field of sports massage and badminton, it has become apparent that there is a vast gap in the literature with regards to the investigating of whether pre event sports massage would benefit the lower limbs in badminton players. There is plenty of literature on both of the separate subjects but none that have been developed as one research project. This is even more apparent within the field of women’s sport and badminton in particular, most of the projects that have been undertaken within these fields have been associated with men only or as part of a mixed sex group and therefore the researcher has not been able to gain a definitive answer of whether the testing has significantly affected females in a positive/negative way or in no way at all. Therefore, the research question in mention during this project is definitely justified as results are required to find a definitive answer to enable coaches or players to enhance or adjust their training programmes to improve on court sporting performance according to the findings from this research. 21 Tanya Chick –ST08003621 CHAPTER THREE METHODOLOGY AND RESEARCH DESIGN Tanya Chick –ST08003621 3.0 Methodology and Research Design 3.1 Participants The female participants recruited all had had at least a year of previous badminton experience and were currently playing/training within a badminton team for a minimum of two sessions per week. All female participants were also competing at a minimum level of either University or Local Club standard and ranged between the ages of 18 – 21 years old. Nine female participants were recruited by the researcher by actively going out into the University of Wales Institute, Cardiff’s Female Team or Local Clubs and approaching the coaches or chairmen to gain permission to consult the players. All participants also had been injury free within the lower limbs for a minimum of a year prior to accepting the terms of this research project. All participants were also requested to read an information sheet (Appendix A) stating all aspects and expectations during testing; this was also followed by a completion of an informed consent form (Appendix B) and a client assessment form (Appendix C). They were all informed that their details would remain anonymous and safe during and after the study and were given the option to withdraw from the study at any stage without having to justify their reasoning. 3.2 Testing Protocols There were three different testing procedures that were executed during this research project. They were analysing speed, endurance and agility within the sport specific movements of badminton. All testing protocols were executed in the same order each time, with a five minute active rest period in between each protocol; they participants were permitted to walk around and have a drink but were not permitted to sit. All testing was performed within the Sports Hall at the University of Wales, Institute Cardiff and each participant executed the three tests twice. They were executed with and without pre event sports massage and were performed exactly a week apart. 22 Tanya Chick –ST08003621 Before each testing session commenced the participant was taken through a fifteen minute badminton and drill specific warm up, which was always led by the project researcher to ensure that all participants always endured the same warm up throughout the project. The warm up has been explained below and the same procedures were always followed: Table 4 - Warm up Protocol Duration Exercise 4 minutes Running forwards, sidestepping and running backwards along the lines of the court. 2 minutes Dynamic lunges along the length of the court. 2 minutes Heel flicks and High Knees along the length of the court. 2 minutes Leg Gates, opening and closing of the legs along the length of the court. 2 minutes Jump squats and stationary squats 3 minutes Half speed shuttle runs along the length of the court. The warm up was always led immediately before the testing commenced, therefore when the participants were due to execute their tests with the delivery of pre event sports massage, the massage was performed prior to the warm up, during the non massage protocols the fifteen minutes prior to testing consisted of active rest, which was suggested Lin et al (2007). Participants underwent a fifteen minute pre event lower limb sports massage or fifteen minutes of active rest before completing a structured fifteen minute warm up, participants were then required to execute all three testing protocols in the order of; Speed, Endurance and Agility. 23 Tanya Chick –ST08003621 3.2.1 Test 1 - Speed Shuttle Run – Refer to Figure 1 A smart speed timing gate (smart speed, Fusion Sport, Brisbane, Australia) was placed fifty centimetres away from the ‘T’ Line on the court (which was located directly in the middle of the two service boxes and lines). A marker was then placed a hundred centimetres away from the ‘T’ line, with white insulation tape, to ensure the participant had a clear starting/finishing point when performing the test. Markers were also then placed along the inside tramlines of the services boxes on one side of the court to enable the shuttles (Yonex AS30) to be placed in the same position every time during testing. The length of the middle service line was measured and divided into four to enable the shuttles to be spread out equally. The first shuttle was always placed from the back singles service line and the other shuttles were then measured out equally from this point forwards. This again was marked out with white insulation tape. Four feather Shuttles were then be spread out evenly along the markers that have been highlighted above. A white insulation tape marker was also placed half way along the centre service line, which was the point in which the participants had to return to after tapping each shuttle. After all the equipment was in place, the participant started on the first white marker which was placed a hundred centimetres away from the ‘T’ line, they then ran at maximal speed through the smart speed timing gate to the centre on court marker. They then began to move to the shuttlecock that was located nearest to them on their racket side. (e.g right handed, moved to the first shuttle on the right hand side or vice versa). They tapped this shuttle with their badminton racket head and after performing this they moved rapidly to return back to the middle marker and proceed to the next shuttlecock closest to them on their backhand side. This was then repeated until all of the shuttlecocks had been knocked away from their markers in sequence. Once all the shuttlecocks had been manoeuvred from their markers, the participants then chasseed backwards through the smart speed timing gate to complete that one attempt; this is to ensure badminton specific movements are being executed throughout testing. After the participant had completed the first run, one minute recovery was then timed on a stopwatch (fast time 5 dual display,stopwatch, Leicestershire, England) in which time the participant was permitted to have a drink and walk around but was not 24 Tanya Chick –ST08003621 permitted to sit down at any point. The participant then repeated the speed shuttle run twice more, to make their attempts a total of three, with a minute rest in between each run. Figure 1 – Speed and Endurance Shuttle Run Layout 1 2 3 4 1 5 6 7 8 Key = starting/finishing position = Smart Speed timing gate = middle marker (return point) (smart speed, Fusion Sport, Brisbane, Australia) = Shuttlecock (Yonex AS30) 25 Tanya Chick –ST08003621 The second test was recognised as being the endurance shuttle run, this was similar in set up to the speed shuttle run, however the end result that was being researched was different, and this procedure has been stated below: 3.2.2 Test 2 - Endurance Shuttle Run – Refer to Figure 1 The endurance shuttle run was marked up in exactly the same manner as the speed shuttle run, refer to figure 1. The smart speed timing gates were used during this test to gauge the timings of each run performed. However, the researcher used a stopwatch (fast time 5 dual display,stopwatch, Leicestershire, England) to determine a forty five second rolling clock for each run that was performed by the participant, as this test was designed to find the overall endurance of the participant and not their speed. The participant attempted a shuttle run, just as previously executed in the speed shuttle run, but this time they had forty five seconds to complete the run and the time remaining after their attempt was their recovery time. (e.g. the attempt took fifteen seconds, recovery time was therefore thirty seconds before they executed their next run) This test was executed eight times to determine endurance and the researcher also informed the participant of how long they had left before their next attempt was required and they were given a three, two, one, go, countdown to let them know when to start again. Table 5- Time the participant must execute each run Shuttle Attempt Time to begin (seconds) 1 45 2 90 3 135 4 180 5 225 6 270 7 315 8 360 26 next attempt Tanya Chick –ST08003621 The final test that was executed by the participants during this research project was identified as the on court agility test. The procedure for this has been explained below: 3.2.3 Test 3 - On Court Agility Test – Refer to Figure 2 This test involved the participant manoeuvring themselves around the court to all four corners in a sequential manner. Markers were placed on the cross sections of the inside lines on the court, with white insulation tape to enable the participant to see exactly where they had to run too. Again a white marker will also be placed half way along the centre service line, as this will be the middle marker that the participant must return to after manoeuvring to each corner. Another starting marker was positioned at the rear of the court this time, which was a hundred centimetres away from the back tramline and the smart speed timing gate was positioned fifty centimetres away from the back tramline. These were positioned from the rear of the court this time as the participant was running through the speed gate towards the net as they were simulating forehand and backhand shots at the front and rear of the court. This made the test much more game specific. To begin one attempt, the participant ran at maximal speed from the starting marker through the smart speed timing gates and firstly ran to the middle marker. They then moved towards their forehand front court corner with a racket in their dominant hand, in the same way in which they would move during a game situation (sidestepping/chassee) and place their foot on this marker; once this was executed they then moved back to the middle marker and then did the same with the backhand front court corner. This then occurred again with the forehand and backhand rear court corners. Once the backhand rear court corner had been hit, they moved back to the middle marker for a final time and chasseed backwards through the speed gate to finish that attempt. This was executed three times in total with the researcher timing a minutes rest on a stopwatch in between each attempt. The participants were again requested to not sit down during their rest periods but were permitted to walk around and have a drink. 27 Tanya Chick –ST08003621 Figure 2 – On Court Agility Test Layout Key = Corner 1 (Forehand Front) = Corner 3 (Forehand Rear) = Corner 2 (Backhand Front) = Corner 4 (Backhand Rear) = Middle Marker (return point) = Starting/Finishing Position = Smart Speed Timing Gates (smart speed, Fusion Sport, Brisbane, Australia) 28 Tanya Chick –ST08003621 3.3 Massage Protocols During the testing the participants were doing two sets of testing days, one with pre event sports massage and one without. A crossover design was adopted with regards to the testing protocols with the aim to reduce the effects of behavioural patterns in reference to learning effects with and without massage, which was stated by Gratton and Jones (2010). During the massage protocols, the researcher had to make the testing and massage delivered as standardised and reliable as possible to ensure that all participants received the same treatment before entering into testing. This also ensured that the results were reliable and valid due to everyone being treated with the same massage prescription. Massage was executed by the same qualified sports therapist throughout the project with the aim to eliminate inter practitioner variability and it was executed on a massage plinth by using hypoallergenic oil as a medium. A stopwatch was also used to enable the practitioner to see exactly how long they had to deliver each technique on each muscle group. Massage was delivered for duration of fifteen minutes on the anterior and posterior lower limb muscle groups. Two and half minutes were delivered to each section of the limbs; upper and lower posterior and upper anterior muscle groups of each limb. As previously analysed in the literature review in this project, a specific set of hand techniques have been adopted for a specific duration on each muscle group; this procedure has been noted in figure 6. The massage was executed in a particular order on each participant, which consisted of treating; the right hamstring muscle group, followed by the right calf and the finally the right quadriceps muscle group and then the same procedure was adopted for the left leg to complete the massage. The techniques listed in table 6 were also executed in this order on every participant. One week before the testing occurred the participants were required to attend an information and familiarisation session with regards to the massage. This was achieved to ensure that participants were aware of what techniques and tempos were to be delivered during testing. 29 Tanya Chick –ST08003621 Table 6 – Pre Event Sports Massage Protocol for each section of both limbs (Upper and Lower Posterior and Upper Anterior Muscle Groups) Duration (seconds) Massage Delivered Speed and Depth 90 Effleurage: Superficial and Fast Tempo Flat hand (15 secs) Rotary (15 secs) V (15secs) Cam and Spindle (15 (12 strokes per 15 seconds) secs) Forearm glide (15 secs) Opposing Glide (15 secs) 30 Petrissage Superficial and Fast Tempo (24 strokes per 30 seconds) 30 Tapotement: Superficial and Fast Tempo Hacking (10 secs) Cupping (10 secs) Flicking (10 secs) (20 strokes per 10 seconds) 3.4 Data Collection and Analysis All data was collected via the smart speed timing gates as they gave the researcher an accurate and reliable reading of the exact times that the participants executed during each testing protocol. As this is a quantitative study, analysis was carried out using Statistical Package for the Social Sciences (SPSS for Windows 19, SPSS, Inc.,Chicago, IL). Graphs and Charts were produced using the computer programme Microsoft Word and Microsoft Excel (Microsoft, USA). A Paired T Test was adopted to analyse the results recorded from all of the testing protocols due to that fact that a paired T test is designed to analyse differences between two groups, the paired T test measures whether the mean of a single group is different when it is measured during different durations. (Gratton and Jones 2010). 30 Tanya Chick –ST08003621 This was used due to the fact that aim of the study was to find whether there was an effect on performance when executing pre event sports massage. 3.5 Ethical Considerations The participants were always made aware throughout the study that their best interests were kept in mind and that the researcher was aware of how the testing days and the possible uncomfortable physical feelings that were demonstrated during testing were aimed to be kept at a minimal level. This was achieved by organising the testing sessions each week, around the schedule of each participant instead of the researcher’s schedule. All participants were always completely motivated and reassured by the researcher throughout testing to ensure that the participants felt at as much ease as possible throughout testing. This ensured that all participants remained willing and available to partake within all testing protocols over the two week duration and to ensure that the study remained valid and reliable by ensuring the same participants were being recorded throughout. 31 Tanya Chick –ST08003621 CHAPTER FOUR RESULTS Tanya Chick –ST08003621 4.0 Results Data displayed as mean ± SD, N=9, significance accepted at p<0.05. M - Massage and WM - without massage. The results shown are in relation to n=9 aged 20.4 years (mean SD) executing three testing protocols which have been identified as speed, endurance and agility. Each test was executed once with massage and once with active rest a week later. To compare the measures of performing the testing protocols, with and without massage, a paired T test was employed. Thomas et al (2011) recognised that if there are two independent groups to be assessed, such as with or without massage, a Paired T Test would be adopted as it would then be possible to judge whether the two groups were significantly different based on the average scores collated. 4.1 Speed Testing Protocol From the SPSS Outputs of the Paired T test results for the speed test analysis, it can be stated that (WM) (17.56 ±2.09 vs. 17.35 ±1.42) (M) = p>0.05. Therefore the Paired T test reported that there was no significant difference between the two controls, of executing massage and performing the same speed tests without massage. Therefore it can be suggested that Speed was not affected throughout performance, either with or without a pre event sports massage. The mean averages of the speed tests for both independent controls have been demonstrated in Figure 3 on the following page; 32 Tanya Chick –ST08003621 18 16 14 Time in Seconds 12 10 8 6 4 2 0 Without Massage Massage Figure 3 – Speed Test Mean Average Results for Both Controls 4.2 Endurance Testing Protocol The endurance test was recorded via the participants, n=9, completing eight shuttle runs at maximal speed. Due to the fact that this test was analysing whether pre event sports massage affected the long term effects of the lower limbs of female badminton players during performance, the results have been outputted into the SPSS Paired T Test in two different formats. Figure 4, has demonstrated the mean average results across all eight attempts, whereas Figure 5, has reflected the overall totals of all eight shuttle runs to determine the participants over all duration to complete all eight shuttle runs. This has been established to enable the fastest shuttle run during the endurance test to be identified and to also see the overall duration of all runs, when completed with and without the massage to see if the participants decreased or increased pace during each independent control. 33 Tanya Chick –ST08003621 18 16 14 Time in Seconds 12 10 8 6 4 2 0 Without Massage Massage Figure 4 – Endurance Test Mean Average Results for Both Controls The endurance test when applying the mean average results demonstrated that WM (17.66 ± 1.9 vs. 17.41 ± 1.64) M = P> 0.05. Therefore considering P>0.05, no significant difference has been accepted and performing massage has not affected the endurance ability of the participants. 34 Tanya Chick –ST08003621 140 120 Time in Seconds 100 80 60 40 20 0 Without Massage Massage Figure 5 – Endurance Test Overall Total Averages for Both Controls From the Paired T test output results for the overall total averages of the endurance test, it was recorded that WM (139.25 ± 13.08 vs. 141.21 ± 15.43) M = P>0.05. Even though it can be seen from figure 8, that the timing during the without massage protocol was slightly increased, due to the fact that P>0.05, no significant difference can be accepted therefore meaning that massage has no significant effect on endurance within the lower limbs of the female badminton players, N=9. 4.3 Agility Testing Protocol The agility testing protocols looked at the mean average scores of all n=9 participants over both independent controls of performing with and without massage. The results stated that WM (8.70 ± 0.53 vs. 8.73 ± 0.44) M = P>0.05. From this it can be seen that as P>0.05, the significance of the results are again not accepted and therefore it is suggested that massage has no affect on the lower limbs of female badminton players, n=9, in reference to agility. The results from the Paired T test outputs have been demonstrated in Figure 6 below: 35 Tanya Chick –ST08003621 10 9 8 Time in Seconds 7 6 5 4 3 2 1 0 Without Massage Massage Figure 6 - Agility Test Mean Averages for both Controls From analysing all three testing protocols, it can now be seen that the original null hypothesis has been accepted as the results clearly identify that pre event sports massage has no significance with regards to affecting the lower limbs in female badminton players within the speed, endurance and agility fields. 36 Tanya Chick –ST08003621 CHAPTER FIVE DISCUSSION Tanya Chick –ST08003621 5.0 Discussion 5.1 Introduction The major findings from this study have suggested that pre event sports massage does not benefit the lower limbs of female badminton players with regards to speed, endurance and agility. All of the testing protocols during this project delivered results that were unable to be accepted and this therefore stated that there was no significant difference between the two independent controls of with and without massage. The following text initially discusses the major findings from each testing protocol and an insight into why these tests may have been inhibited and how they could be improved to enhance future research within a similar field. Practical limitations are then discussed, followed by strengths and weaknesses of this study and why future research within this similar field should be investigated. 5.2 Speed Testing Protocol Speed is a key component within badminton, Bloss and Hales (2001) identified that speed is required to enable any badminton player to manoeuvre themselves around the court to get them into an optimal position to execute a quality shot during a rally. Without on court speed, a player will struggle to maintain quality of shot and have a reduced chance of performing the shots they desire to gain an attacking advantage. They will more than likely end up lifting the shuttle to get out of trouble and therefore immediately giving the opponent the attack and placing themselves into a defensive position which could lead to the point being forfeited. The major findings from the speed testing protocol indicated that there was no significant difference to the results that were collected from when massage was delivered compared to when the participants only had a fifteen minute warm up and no massage as p>0.05. There are many underlying factors that could have been overseen within the speed testing protocol, which could have potentially affected the direct results that were retrieved from the participants, N=9. Goodwin et al (2007) executed a similar research project in relation to the speed aspect but instead of applying it to badminton, the research was formed analysing athletic sprinters, over a thirty metre distance. This is also in comparison to Hemmings et al (2000) who researched into the repeated performance speed of boxers with the aid of pre event sports 37 Tanya Chick –ST08003621 massage; they also found that massage had no effect on speed when performing in a boxing match situation. Goodwin et al (2007) recognised that pre event sports massage had no benefit to the lower limbs in reference to thirty metre sprinting and suggested that the affects of the massage may have dissipated over a course of approximately ten minutes, whether it was due to the time from when the massage was executed up until the first result recorded or whether the fifteen minute active warm up would have received all of the initial benefits that were aimed to be achieved when performing the tests. The massage testing within this project was also executed in this manner, with the participant firstly receiving massage and then negotiating an active fifteen minute warm up directly after the treatment occurred, therefore according to Goodwin et al (2007) study it could be suggested that the pre event sports massage had already dissipated by the time the participant had reached the first speed shuttle run and the effects had therefore worn off and caused no effect to the speed performance. Not only could the massage and testing protocol possibly affect the results that were retrieved, but the participant’s lifestyles and mind states should also be taken into consideration as they could have had major psychological/physiological factors that could have affected their performance during each week. These could have ranged from anything as general as university work load, to stress from family issues or even to lack of sleep. Any of these issues could have mentally or physically drained the participant and this could have had an adverse affect on the results that were retrieved. For future testing it could be suggested that a pre event sports massage is executed to the participant after the fifteen minute warm up has been performed, this could then resolve the issue of the effects of the massage dissipating within ten minutes of the treatment being delivered, as previously mentioned by Goodwin et al (2007). The independent controls could then be changed to with massage before a fifteen minute warm up and with massage after the fifteen minute warm up, which could potentially educate coaches/players about the benefits of including a pre event sports massage into a performance regime, immediately before game play. 38 Tanya Chick –ST08003621 5.3 Endurance Testing Protocol All testing within this project directly relates to on court situations and movements/patterns that are repeated several times during a game/rally. Lees et al (2004) discovered that the average rally duration within badminton is often around four to five seconds, with rest periods of approximately ten seconds and therefore the players will be actually playing for approximately a total of 35% during a standard rally. These statistics demonstrate that the endurance testing protocol within this research project is transferable in comparison to a game/rally situation as the test also involves the participants performing short, intense bouts of speed and power and then recovering for approximately fifteen seconds, dependant on the speed of each participant. The major findings within the endurance test consisted of the results being rejected as p>0.05 and therefore the effects of pre event sports massage had no significance with regards to improving on court endurance. Even though the results were rejected within this protocol, it was recognised that the majority of the participants produced their fastest times during the first and last shuttle run. This occurrence should not normally be present within an endurance test, as Cabello et al (2004) stated that endurance is recognised as being a part of the aerobic glycolytic energy system and is designed to last over a longer duration of time but at a decreased pace compared to an athlete that may be competing anaerobically. However with regards to badminton and the intensity of the demands sustained throughout a whole match, the phosphocreatine system is required. Therefore results times should be faster at the start of testing and should slowly start to decrease in duration as the testing progresses. Ogai et al (2008) suggested that psychological and physiological factors affect how a participant would approach their final attempt/run of an endurance test. Psychologically, the participant has been made aware that they are finishing their final attempt and would therefore produce as much energy as possible to ensure the test is over faster. In a study produced by Cabello et al (2004), it was recorded that female badminton players work less and rest for longer periods of time throughout a game/competition in comparison to male players, this could directly affect the physiological aspects of the endurance testing as the woman participants, N=9, may not have been performing above their optimal level the whole way through the eight shuttle runs due to the fact that they are constant and 39 Tanya Chick –ST08003621 consistent and as Cabello et al (2004) stated the work periods are often shorter and rest is longer, which is in contrast to this testing protocol. It could therefore be advised, for future testing to avoid informing the participants of how many shuttle runs they have executed to ensure that they remain consistent with their performance and to reinforce that they must work optimally from the very first shuttle run until the final run is complete. This would better represent a game situation and would make the endurance indicator more reliable for future research. A final physiological aspect that could be considered as a hindrance during this testing protocol, was the fact that the participants sometimes forfeited the correct footwork patterns to enable themselves to complete the shuttle run in the fastest time possible, Kutze et al (2009) also experienced this dissipation of technique performance as they were recording results for lateral side stepping and crossover stepping tasks in badminton. It is therefore suggested that when executing the endurance test protocol in the future, that the participants should be made aware that they have to uphold correct footwork at all times and that their leading foot must be placed directly over a fixed marker on the court, which will ensure that all participants are covering the same area of the court every time they complete a run. This will therefore make the test more reliable and transferable into a game situation with regards to efficient and correct footwork. The massage executed prior to the testing could have been another limitation factor with regards to endurance due to the fact that it is recognised that the physiological effects of sports massage dissipate after ten minute duration and as the endurance protocol would have been performed after the speed protocol, it could be suggested that the effects had diminished by this point. (Goodwin et al 2007). There are also minimal amounts of literature that actually prove that the physiological effects of massage exist, such as; increased circulation, metabolism and waste removal. (Paine 2000). Due to this, if the physiological effects do not actually exist then there would naturally be no effect on performance with regards to endurance. 5.4 Agility Testing Protocol Baechle and Earle (2008) recognised that agility is the skills and abilities to explosively change movement velocities or modes. Kuntze et al (2004) directly related this to badminton as the main footwork techniques involves the participant/player to manoeuvre themselves 40 Tanya Chick –ST08003621 around the court at explosive speed with repeated rapid changes in direction with the aim to get underneath the shuttle to play the optimal shot required. The major findings recorded within the agility testing protocol discovered that pre event sports massage had no significant affect on the lower limbs of the female badminton players, N=9, with regards to improving on court agility as P>0.05. Several implications with this test have been raised with suggestions that may explain why the results had to be rejected and why no significance was identified with reference to using pre event sports massage. The main considerations have been identified as being physiological aspects but psychological implications have also been suggested. The agility test was the last performance that the participants had to execute and therefore as previously mentioned by Goodwin et al (2007), if the massage affects do dissipate ten minutes post treatment, then the pre event sports massage would not have had any contribution towards this agility testing as this was normally performed approximately twenty to thirty minutes after the massage was delivered. Future research considerations for this testing protocol could incorporate inter event massage along with the pre event massage. Findlay (2010) identified that inter event sports massage is designed to prepare the athlete/player for the next event within their competition and could aid to flush out and prepare the tissue within the muscles for further work. This research would then enable coaches/players to identify whether incorporating a quick and superficial massage before each game/end within a badminton competition, benefits the lower limbs within the aspects of speed, endurance and agility. Not only could the massage protocol effect the way in which the agility test was executed by the participants but muscle memory for the desired on court pattern could also have contributed towards the results. Lin et al (2007) discovered that when participants had to perform a designated set of specific movements over two sessions spread over two weeks, the majority of the time the participants’ durations were higher during their first attempt at the exercises but as the participants had then already performed the movements once before they were then aware of exactly how they had to perform the exercises and were more confident and efficient whilst executing them during the second attempt. 41 Tanya Chick –ST08003621 Baechle and Earle (2008) stated that muscles can adapt to everyday situations and will remember certain pattern that have been executed before, this is done subconsciously but when the athlete attempts the same movements again, the muscles are aware that this has been replicated before and the action becomes easier to execute, this is particularly present when performing Olympic lifts such as the snatch or the clean and jerk. Future testing could include a test for learning effects between the first and second week of testing, to enable the researcher to identify if this has a significant difference as this could benefit coaches and players by making them aware that if they continue to practice techniques within their training, they could potentially adapt and execute the techniques/footwork required faster and more efficiently. 5.5 Practical Implications The results of this study demonstrated that pre events sports massage had no significant effect with regards to the lower limbs in female badminton players in reference to speed, endurance and agility. Regardless of the insignificance of the results gained, it could still be beneficial to inform badminton coaches or players about these current findings as they will then be able to decide for themselves whether they believe that pre event sports massage is beneficial to their athlete or whether they would prefer to adopt a different modality pre competition with the aim to improve/effect the player in a positive manner. Lin et al (2007) suggested that the incorporation of an Inspiratory muscle warm up prior to performance enhanced the player’s footwork when executing a set of incremental badminton footwork tests. An inclusion such as this style of warm up could be focused on instead of applying pre event sports massage if the coach/player believes that a technique such as this could aid improvement of performance. Pre event sports massage did not show any significant effect within this study, this was also apparent within the studies of Barlow et al (2002), Goodwin et al (2007) and Hemmings et al (2000). These results could have been affected due to many aspects of the study whether it could have been due to an insufficient sample size; the methodological processes adopted or even the massage protocol adopted. 42 Tanya Chick –ST08003621 However, even though a significant physiological effect is not recorded, massage is currently still executed as a pre event modality within many sports. Weinberg et al (1988) discovered that pre event sports massage produced a positive mood enhancement when completing vigorous exercise. A decrease in fatigue, anxiety and tension were also recorded and therefore causing positive mental health. Techniques such as Tapotement are also seen as a modality to get the athlete into a mental state of preparation along with stimulating the muscles treated, which will ensure that the player feels physically and mentally ready for the competition, which was recognised by Weinberg et al (1988). Tapotement is a form of pre event sports massage that aims to stimulate skin, muscle contractions and sensory receptors and it is a fast paced and superficial technique. (Findlay 2010) This could therefore justify the continuation of executing pre event sports massage before an event/competition. If the player believes in the modality that is being used and that it will enhance their performance/wellbeing then there is every reason to treat the athlete with this form of preparation technique. However, as there has been no definitive literature within this study in regards to the aspects of speed, endurance and agility or within the studies of Barlow et al (2002), Goodwin et al (2007) and Hemmings et al (2000) whom also researched within the same fields, it could be suggested that pre event massage may also cause a hindrance within other aspects of a badminton players performance. Arabaci (2008) discovered an adverse effect on vertical jump height and reaction time after executing a pre event sports massage. This could have been due to the fact that within the massage protocols, the researcher adopted the use of frictions as a hand technique, which is a technique that is widely recognised as a rehabilitative measure and is not often performed as part of a pre or inter event massage due to the fact that it is often executed to remodel scar tissue and collagen and not to promote increased circulation or stimulation as most pre/inter event techniques do. (Copyright SPSS ltd 2003). These two factors are also important within the sport of badminton as vertical jump height is represented when attempting to perform a jump smash and reaction time is a constant factor required within a game as the shuttle is being manoeuvred all around the court at different 43 Tanya Chick –ST08003621 speeds and angles. Therefore if these two components were to be negatively affected it could be extremely detrimental to quality of performance and shot technique which could eventually lead to the player(s) losing the match/competition. (Downey1993). Due to the inconsistency of evidence within previous literature and the insignificant results that were gained from this study, the use of pre event sports massage would be left entirely down to preference and the beliefs of the players/coaches as to whether they would incorporate it into their preparation programme. 5.6 Limitations of this Research Project Despite using a well practiced and relative methodological process to execute all protocols during this research project, there are many limitations that could have been present which as a result could have directly affected the findings stated. Firstly the participants were chosen carefully by a selection protocol which was earlier stated in the methodology section of this study; however there are certain factors that were out of the control of the study that may have occurred without the researcher’s recognition. For example, the participants were requested to not partake in any physical exercise or to consume any alcohol twenty four hours before the testing commenced, even though this was stated from the start, there is no way of the researcher knowing whether this actually occurred or not. Furthermore, physiological characteristics within the participants may have caused the results to be vastly insignificant. Baechle and Earle (2008) identified that the cardiovascular system is designed to deliver oxygen and other nutrients around the body to the muscles. Anaerobic and aerobic training enables the heart to pump blood, along with the oxygen and nutrients, around the body more efficiently and in larger quantities, which enables the muscles to work for longer periods of time and with a relative amount of ease. Therefore if some of the participants took part in physical activity more frequently and vigorously than others, then the tests that were executed during this study would have been easier to complete than someone who does not train as often. Future prevention of this issue could include a more specific recruitment process with regards to the participants. It could be suggested that participants had to train for a certain number of sessions a week, e.g. all participants must train for three sessions a week. 44 Tanya Chick –ST08003621 A more in depth background check into extra curricula activities of each participant could also be adopted with the aim to find the individual fitness levels of each participant. Another underlying issue was a lack of current literature within the area of pre event sports massage as this could have adversely affected the results collected. This is due to the fact that most of the previous studies that were reviewed lacked the precise method in which the pre event sports massage was delivered. All studies in table 2 (Literature Review), mentioned the hand techniques that were adopted and for the duration in which they were executed, however the depth and the tempo of the strokes were neglected to be identified and therefore increasing the difficulty to determine which methods were the best option to adopt during this study or for future replicability. It could be suggested that a future study may benefit from using a different pre event sports massage protocol, such as different hand techniques, longer/shorter duration, faster/slower tempos and increased/decreased depth to ensure that the methods used during this study were not the only methods to retrieve an insignificant affect. Cabello et al (2004) completed a study analysing the physiological characteristics of players whilst competing on court during a tournament with the aim to discover which energy system was best suited for the players in a competitive situation. These results enabled the researchers to identify how long male and female players worked and rested for during a game and which energy systems they were using which enabled coaches and players to develop training programmes around the required energy system with the aim to improve performance. A similar protocol could be adopted but with the use of the pre event sports massage prior to competing, this would then ensure that all participants are working at their maximal levels and are psychologically prepared for the task in hand. The strengths of this study enabled coaches to identify how important the aspects of speed, endurance and agility are within a badminton context and how they should develop future training programmes or adopt massage interventions into their preparation regimes with the aim to improve performance during a match/competitive event. 5.7 Future Research Cabello et al (2004) noted that speed, endurance and agility are all key components within a badminton match/competition and due to the fact that this study found that pre event sports massage had no significant affect with regards to these components, it is important to 45 Tanya Chick –ST08003621 address possibilities for future research with the thoughts of improving the performance of badminton players and how the player/coach can incorporate this within their preparations. The main priority for future research has been considered as incorporating inter event massage as well as pre event massage, this is due to the fact that Goodwin et al (2007) recognised that the effects that are gained from pre event sports massage dissipate after ten minutes and therefore this could be suggested that the three testing protocols of speed, endurance and agility were not affected by the massage executed. Therefore, by including pre and inter event massage to the same tests this will give a clearer indication as to whether the massage actually affects performance. If this research did identify that the massage positively affected the player’s performance, a sports masseuse could be recruited to treat the player before and during match/competition games. However, a few impracticalities may surface with this mode of collecting data due to the fact that there is a minimal amount of time between changes in ends and usually during this time the coach will be implementing advice and also rehydration can only take place during this break too, therefore leaving minimal time to perform massage and gain the results required. In contrast to this a future study could also be developed to analyse the affects of a specifically designed training regime, over a set duration of weeks that directly relates to the protocols that were executed during this study (speed, endurance and agility). Baechle and Earle (2008) mentioned that a mesocycle could be developed within a Periodization programme that could be split into two smaller microcycles which often last from anywhere between one and four weeks and are usually focused on daily or weekly training variations. This could therefore be adopted for future research in the aim to find if specific training regimes can directly enhance the protocols analysed (speed, endurance and agility) over the mesocycle programme with final testing of each aspect at the end of the programme. If the results gained from a study such as this show a positive effect to specific training regimes, coaches will then be able to prescribe similar exercises/regimes to their own players to improve their performance on court and during competition. 46 Tanya Chick –ST08003621 CHAPTER SIX CONCLUSION Tanya Chick –ST08003621 6.0 Conclusion 6.1 Major Findings The results of the study demonstrate that pre event sports massage has no significant affect on the lower limbs of female badminton players in relation to speed, endurance and agility. Due to the importance of speed, endurance and agility within badminton (Bloss and Hales, 2001) it is vital that research continues to occur within these areas with the aim to improve performance in these fields. If this can be achieved, players/coaches will then be aware of what preparations they need to adopt to ensure the player(s) are achieving their optimal results in a match/competition. Future Studies should therefore be directed towards investigating the affects of pre and inter event sports massage with the aim to find whether it will improve performance within the speed, endurance and agility fields. It is also suggested that the testing protocol is incorporated within a match/competition environment; this will ensure that the participants are motivated and performing at their maximal outputs instead of decreasing their efforts, which could have been present within this study during the testing protocols. Additionally, future studies should be directed towards the clarification of the preparations that are required to ensure that future players/coaches, perform at an optimal level within all three disciplines of speed, endurance and agility when in a game/competition situation. 47 Tanya Chick –ST08003621 REFERENCES Arabaci, R.

Participant Information Sheet Background This investigative study has been constructed to attempt to find a positive relationship between sports massage and effective movement and physical performance on court within badminton. Tanya Chick (the Researcher) a 3rd year student at UWIC University, will be undertaking the experiments and tests. The main aims of this investigative study are to enable badminton players to: Gain more efficient and beneficial movement patterns whilst competing on court. Reduce fatigue and lactic acid build up within the muscles to enable longer performances. Feel like they can take anything on and be more positive as a result of the massage (fight or flight theory). This study will be presented as an assignment in a Year 3 student Dissertation as part of an undergraduate University Sports Conditioning, Rehabilitation and Massage Degree. Your Participation in this Project Why you have been asked You have been asked to participate in this project as it is believed that the data that is collected from your results will aim to benefit the sport of badminton a significant amount, if the hypothesis is proven to be correct. Therefore, as you are a badminton player this could directly affect you and your future performance positively. What would happen if you agree to participate within this study There are 3 main things that will occur: 1. You will come in to have a briefing session and a pre testing massage assessment, to see how you react to the massage techniques. You will also read and sign all necessary documents, including the informed consent. 2. A week after this briefing you will come in to the sports hall of the University Of Wales, institute Cardiff where you will perform a fifteen minute dynamic warm up, which will be executed by me, Tanya Chick. You will then perform a set of three physical movement tests on the badminton courts. Tanya Chick –ST08003621 These will consist of: Speed shuttle run: Starting at the back of the court and at maximal speed moving to the shuttles placed on the court and tapping each one with your fingers, until all shuttles are moved from their destination in the order stated. This will be repeated three times, with a two minute recovery period in between runs. An endurance shuttle run: The same as the test stated above however, this is now done on a rolling clock of forty five seconds, once you have completed each shuttle run; the remaining time left from your forty five seconds is your recovery period. This will be completed ten times, with two minutes rest period between each run. An on-court agility test: Starting from the back of the court you will run through the smart speed gates at maximal speed and manoeuvre yourself around the court in the designated order whilst using the correct footwork patterns, to get to all four cones, in each corner of the court. This will be done three times with a two minute rest period in between each set. 3. Finally, another week later you will perform the same tests again but this time with the aid of sports massage for fifteen minutes directly before testing. The non massage based tests will take approximately forty five minutes and the massage based testing will take approximately one hour. Are there any Risks? There are no direct risks to you or your health, the only issues that will affect you will be the physical fatigue from the tests. Your Rights Throughout this study, if at any time you decide you do not want to take part you may inform the investigator and not even have to give a reason. You should not feel like you are being forced to do any of these tests, it is completely voluntary. This will not in any way affect your legal rights. What happens to the results of the evaluation?
