Differences In The Effect Of Aerobic Exercise With Anaerobic Exercise Against Malondialdehyde (Mda) Levels In Wistar Rat (RattusNovergicus) Heart Muscle Aristoteles Lecturer Of Nursing Diploma Program STIKes Muhammadiyah Palembang E-mail: [email protected] ABSTRACT Introduction: Effect of physical exercise on biological function, which is positive effect in terms of repairs cells and negative influences that inhibit or damage the cell. Strenuous physical exercise can cause muscle injury and oxidative stress in individuals who are not conditioned or not accustomed to physical activity. In addition to oxidative stress also plays a role in chronic fatigue syndrome. This happens due to the velocity exceeds the speed of energy needs and the ability of oxygen transport system to supply oxygen into mitochondria. The heart muscle is a muscle that has a major role in physical exercise, oxidative stress plays an important role in the pathogenesis of myocardial infarction. although it has been known that exercise can produces free radicals, but how much difference the effect of aerobic exercise with anaerobic exercise against the formation of free radicals, The information is relatively very limited. Formation of free radicals can be predicted by measuring the levels of malondialdehyde (MDA). Method: The design used in this study is in the form experimental vivo study with pretest-posttest design with a comparison group. The subjects were 28 Wistar rat rattus strain novergicus males are divided into 6 treatment groups and 1 control group. Data retrieved by doing physical exercise treadmill with speed 20m/minute for aerobic exercise and 35m/minute for anaerobic exercise. Different test average MDA levels using independent t-test, Anovaand post hoc. Results: The results showed decreased levels of MDA in the aerobic and anaerobic treatment group compared with the comparison group. The analysis showed that there were significant differences between the aerobic group 1 day, 3 times a week and 7 days in a row with p<0,05. In the opposite there was no significant difference between groups anaerobic with p> 0,05. Conclusion: aerobic and anaerobic exercise is performed 1 day, 3 times a week and 7 days in a row can increase the antioxidant defense system that decreases oxidative stress characterized by decreased levels of MDA.

The positive influence of physical exercise will improve your health and physical fitness if performed regularly, programmed and measured properly . Physical exercise will improve and also slow down the decline in organ function , and can raise the immune function . Physical exercise is performed with maximum intensity and exhausting it generates oxidative stress ( Harjanto , 2004) According Lipon et al ( 2012) free radical formation in high intensity aerobic exercise leads to leakage of electrons to the respiratory chain and free radical formation during high -intensity anaerobic exercise occurs during reperfusion of blood on the tissue resulting in leakage of electrons to form free radicals . During physical exercise oxygen consumption in the body can be increased up to 20 times while the consumption of oxygen by the muscle tissue is expected to increase up to 100 times . Generally 2-5 % of the oxygen used in the metabolic process is converted into superoxide ions that result in 2 increased production of free radicals ( Urso , 2003) . Although it has been known to anaerobic exercise can produce free radicals , but how much difference between the effect of aerobic exercise with anaerobic physical exercise on the formation of free radicals , the information to date is relatively very limited . Formation of free radicals can be predicted by measuring the levels of malondialdehyde (MDA) (Purnomo , 2011). Free radicals are atoms or groups of atoms that have one or more unpaired electrons in their outer orbitals ( Halliwell & Whitteman , 2004) . One type of free radicals are reactive oxygen compounds ( reactive oxygen species / ROS ) that contain unpaired electrons , ie electrons in their orbitals alone . These electrons have a tendency to attract electrons from other molecules , so it is classified as ROS free radicals have high reactivity . Molecular oxygen ( O2 ) has a lower oxidation capabilities of the other chemical components . Therefore, more oxygen is easily transformed into a more reactive oxygen , this is called oxygen free radicals (Pinnel et al, 2007) . Strenuous physical exercise can lead to muscle injury and oxidative stress in indivdu the INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 unconditioned or unaccustomed physical exercise . In addition , oxidative stress also plays a role in chronic fatigue syndrome. This happens due to the velocity exceeds the speed of energy needs and the ability of oxygen transport system to supply oxygen into mitochondria . Increased production of lactic acid will change the weak free radical ( superoxide radicals ) becomes a powerful free radical ( hydroxyl radical ) that has the potential to cause tissue damage ( Clarkson & Thomson , 2000). Tissue damage is a condition in the body that lead to impaired function of a network . According LiPON et al ( 2012) the one that triggered the tissue damage is the imbalance between the production of oxidants and antioxidants . If this continues to result in interference with the various organs . Several indicators can be used as a sign of tissue oxidative stress , such as by measuring the levels of malondialdehyde ( MDA ) ( HD & Bijoor , 2103 ) . Increased levels of MDA occurs because the body's antioxidant system is not able to fight free radicals . Electron donating compounds or all of the compounds that can reduce the negative impact oxidants including enzymes and metal -binding proteins ( Battineli , 2000). PURPOSE OF RESEARCH General purpose 3 To compare the differences in the effect of aerobic exercise with anaerobic against MDA levels in heart muscle novergicus wistar strain rats Rattus Specific purpose • To analyze the differences in the levels of MDA in heart muscle Rattus novergicus wistar strain before and after aerobic exercise . • To analyze the differences in the levels of MDA in heart muscle Rattus novergicus wistar strain before and after anaerobic exercise . • To be able to analyze the comparative levels of MDA in heart muscle strain Wistar rats Rattus novergicus who perform aerobic exercise with anaerobic. METHODS Types of Research The design of this study is an experimental study in the form of in vivo ( Dahlan , 2009) . Population and Sample The population of the study, subjects using rat Rattus novergicus male Wistar strain obtained from the laboratory of the Faculty of Veterinary Medicine , Bogor Agricultural University . Samples were Rattus novergicus wistar strain male with 6-8 weeks of age who met the inclusion criteria . In accordance with the INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 study design , mice were divided into 7 treatment groups : P1 : control group, were not given the imposition of physical exercise P2 : The group given the imposition of aerobic physical exercise for 1 day P3 : The group given the imposition of aerobic exercise 3 times a week P4 : The group given the imposition of aerobic physical exercise for 7 days in a row P5 : the group given the imposition of anaerobic physical exercise for 1 day P6 : the group given load during anaerobic exercise 3 times a week P7 : the group given the imposition of anaerobic physical exercise for 7 days in a row RESULTS Comparison of MDA In the treatment group Aerobic (P2,P3,P4) with Comparison group (P1) Measurement results of MDA in the aerobic group ( P2 , P3 , P4 ) are listed in Table 4.1 , compared with the comparison group MDA value (P1) with the unpaired t-test (P <0.05). The results show that there is a decrease in the levels of MDA in the aerobic treatment group P2 , P3 and P4 than the comparison group, are listed in the following table 4.1: 4 INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 4.2. Comparison In Anaerobic Group ( P5 , P6 and P7 ) With Comparison Group ( P1 ) Measurement results of MDA in the anaerobic group (P5 , P6 , P7) compared with the comparison group MDA levels ( P1 ) are listed in Table 4.2 , further with unpaired t-test ( P <0.05 ) , results showed that MDA levels decreased heart muscle tissue anaerobic treatment group compared with the comparison group and are listed in Table 4.2 below: 4.3. Comparison Between Aerobic And anaerobic group Measurement results of MDA in 5 the aerobic group (P2 , P3 , P4 ) are listed in Table 4.3 , compared with MDA anaerobic group (P5 , P6 , P7) by unpaired t-test ( P <0.05 ) . The results obtained showed that no significant difference in heart muscle tissue MDA levels between groups of aerobic with anaerobic group , where the results are shown Table 4.3 below : DISCUSSION MDA In Myocardial strain Wistar Rats Rattus novergicus Before and After Aerobic Physical Exercise In this study it was found that there was no significant difference in heart muscle MDA levels in the treatment group aerobic exercise 1 day , 3 times a week and 7 days in a row with the comparison group (p> 0.05) . According to the INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 researchers, this suggests that the aerobic exercise done in 1 day would lead to a greater oxidative stress than if physical activity is performed daily or 3 times a week. On physical activity 3 times a week and 7 days in a row of MDA on the network is not a significant increase when compared to physical activity is only done one time , this is due to the frequency of 3 times a week there is a resting phase and the frequency of exercise with 7 consecutive days also arise adaptation response. ANOVA test results in group 1 day , 3 times a week and 7 days in a row between the aerobic group obtained a significant difference where the value of p = 0.04 . This suggests that aerobic physical activity performed each day resulted in cardiac muscle adaptation response to a given load , so dijaringan MDA levels decreased . This is consistent with research conducted by Ascensao et al ( 2007) study of experimental method but a different number of samples , suggesting that the effect of physical exercise can occur immediately called the acute response and long-term effects as a result of regular exercise and programmed called adaptation . physical exercise performed more frequently will cause the heart muscle adaptive response to the exercise ( baler et al , 2012) . Physical exercise habit that has 6 become very important to maintain and improve the antioxidant capacity of natural antioxidants to survive the attack of reactive oxygen . In individuals who exercise regularly occurring antioxidant capacity greater than that of free radical oxidative stress will decrease . High aerobic capacity significantly increases the activity of catalase and superoxide dismutase in muscle (Sen , 1995). Research Sen and Ji (cit Gul, 2003) also stated that aerobic exercise performed on a regular basis can also improve antioxidant defenses.These results are also consistent with research conducted by Gul et al (2006 ) with the same form of treatment , but the number of sample methodology exeperimental different states that, in mice that physical activity using a treadmill cardiac muscle MDA levels lower. The research conducted by Liu et al ( 2000) found that MDA levels of heart muscle and skeletal muscle there is no significant difference compared with the control group . In contrast to mice that physical activity in the form of exhaustive swimming MDA levels increase heart muscle. Basically to exercise in the human body can trigger endocrine activity of neurons . Changes in neuronal activity of the endocrine effect on the production of catecholamines which produce energy . Sport activities undertaken will increase the need INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 for oxygen to produce energy through respiration . Available oxygen is not entirely used up by the body to produce energy , residual oxygen is what amounts to ± 4-5 % , which will form free radicals , forming reactive oxygen species (ROS) and this situation will lead to peroxidation of fatty acids are unsaturated plural ( polyun - saturated fatty acids ) from the cell membrane and thus affects the function of blood cells and can damage the cell 's life ( Clarkson and Thompson , 2000) . If the state is greater than the antioxidant oxidant will cause damaging oxidative stress proteins , and even lead to abnormalities in DNA . An increase in lipid peroxidation due to increased production of free radicals in human exercise is characterized by an increase in malondialdehyde ( MDA ), which is a sign to assess free radicals in the blood . The intensity and severity of exercise performed will affect the production of malondialdehyde (Siswonoto , 2008) . Research conducted by Yin et al ( 2012) stated that the recurrence of cycles of hypoxia and reoksigenisasi can cause the formation of reactive oxygen compounds in the heart of the hypoxic and second trigger a cascade of events that leads to increased activity of the enzyme antioksidan.Hal indicate that ROS production in tissue heart muscle 7 during stress can participate and enable signal transduction pathways that will form a positive feedback to ROS and regulation of transcription factors and causes ROS at low levels which would then mediate the physiological functions of protection mechanisms such as increased levels of antioxidants , also of the mechanism of differentiation and growth myocardial metabolism . MDA In Myocardial strain Wistar Rats Rattus novergicus Before and After Physical Exercise Anaerobic The results of measurements of the heart muscle MDA levels in the anaerobic group found that there was no significant difference in the groups that perform anaerobic exercise 1 day , 3 times a week and 7 days respectively compared to the control group ( p > 0.05 ) . Similarly, the aerobic group mean MDA levels decreased anaerobic group along with the duration of the exercise. According to researchers the presence of adaptation and frequency response of physical exercise contribute significantly to the decline in MDA levels in the heart muscle . This is consistent with research conducted Ana et al ( 2007) with the same methodology but different forms of treatment that , with increasing intensity of physical exercise undertaken will lead to a long- INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 term effect of the so-called adaptation . Physical exercise is done will increase the antioxidant defense system and minimizing expenditure of free radicals. At the time of maximal physical exercise, while the relative hypoxia in some tissues such as organs inactive kidneys, liver and intestines . This is to compensate the increase in the supply of blood to active muscles and skin . After the exercise is completed , rapidly returning blood to the various organs of the lack of blood flow earlier . This process is called " reperfusion " and it is associated with large amounts of oxidants terbebaskannya (Angelos et al, 2006) . Reperfusion can lead to increased ROS production through the conversion of xanthine dehydrogenase (XD) into xanthin oksidase.Keduanya will mengkatalase of changes hypoxanthine into xanthine and uric acid . XD role when enough oxygen demand , XO was instrumental in the state of ischemia . Only catalase involving XO with radical timbunya superoxida . Production of reactive oxygen compounds through this mechanism results in a state of oxidative stress until several hours after maximal physical exercise , and is not limited to skeletal muscle alone (Cooper , 2001) . 8 The results of this study indicate that the anaerobic physical activity performed one time the heart muscle MDA levels higher compared with akitvitas 7 consecutive days . This study is in line with the study conducted by Aydin et al ( 2007) and Venditti & Di Meo (1997 ) which states that physical activity such as swimming performed 1 time until exhaustion causes an increase in the levels of MDA in the heart muscle . Research Aslan (1998 ) found that acute physical activity causes oxidative stress with an increase of lipid peroxidation and antioxidant defense system inefficient contrary research results Gul et al ( 2006) showed that physical activity performed for 8 weeks had no effect on MDA levels of heart muscle mice. According to the researchers, this suggests that the non-occurrence of excessive load on the heart muscle that is characterized by decreased levels of MDA in line with the duration of treatment . Research conducted by Li ( 2013) who said that in individuals who exercise regularly will increase antioxidant that is greater than that of free radical oxidative stress will decrease . Comparison of MDA In Myocardial strain Wistar Rats Rattus novergicus that Perform INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 With Anaerobic Aerobic Physical Exercise The results of measurements of the heart muscle tissue MDA levels in groups of aerobic and anaerobic got that , that there was no significant difference in group 1 day , 3 times a week and 7 days in a row in the group of aerobic and anaerobic . This is consistent with research conducted Starness et al ( 2007) that the effect of physical exercise can occur immediately called the acute response and long-term effects as a result of regular exercise and programmed called adaptation . Including acute response is increased heart rate , increased breathing , increased blood pressure and increased body temperature . The results are consistent with research conducted by Baler et al ( 2012) which states that there is an increase in MDA levels in cardiac muscle tissue after exercise treatment was given for 8 weeks . The same results were put forward by Gul et al ( 2006) which states that there is no significant effect on the mice given the treatment treadmill with a frequency that is often the MDA levels in heart muscle tissue , as well as doing research in Liu et al ( 2000) were observed in tissue MDA levels of heart muscle and skeletal muscle there was no significant difference ( p > 0.05 ) between the control group of rats treated group maximal exercise . 9 According Baler et al ( 2012) the body's natural defense system against free radicals that attack the mechanisms of antioxidant defense system , endurance exercise performed on a regular basis dimitokondria lower levels of hydrogen peroxide , it will potentially reduce oxidative stress and in a study conducted Ascensao et al ( 2007) which states that chronic exercise actually increases the antioxidant defenses. Physical exercise habit that has become very important to maintain and enhance the natural antioxidant capacity to withstand the attack of reactive oxygen . In individuals who exercise regularly occurring antioxidant capacity greater than that of free radical oxidative stress will decrease because it is a high aerobic capacity will increase the activity of antioxidant enzymes in mitochondria (Ana et al , 2007). Effects of exercise performed in a long period of time is certainly increased the activity of antioxidant enzymes superoxide dismutase especially diotot order and glutathione peroxidase in the mitochondria which is the main place of cells that produce free radicals . In general, exercise did not affect the antioxidant in the heart and liver as much influence diotot order , but vigorous training exercises that do cause peningkatann of antioxidants INTERNATIONAL NURSING WORKSHOP AND CONFERENCE “Professional Nursing Practice In Free Trade Era: Threat & Challenge” th th Surabaya, December 6 -8 , 2016 superoxide dismutase in which the left ventricl . CONCLUSION AND RECOMMENDATION Conclusions 1). No significant difference (p>0.05) myocardial MDA levels in the treatment group aerobic exercise 1 day , 3 times a week and 7 days in a row with the comparison group . In contrast to the comparison group MDA levels between aerobic found significant differences (p<0.05). 2). No significant difference in the groups that perform anaerobic exercise 1 day , 3 times a week and 7 days in a row with the comparator (p>0.05). 3). There is no significant difference between the levels of MDA aerobic and anaerobic treatment groups (p>0.05) Advice 1). Results showed that physical activity done regularly to avoid the occurrence of oxidative stress on the heart muscle , therefore, to maintain the health of the heart muscle is not recommended physical activity done every day, but there should be a resting phase of the heart muscle that can perform optimal recovery . 2). Further research should be conducted to determine the ratio of the concentration of MDA in plasma and tissues after doing aerobic exercise and anaerobic 10 exercise , so it can be known mechanism of action of MDA in the body .
