ABSTRACT
Fifteen screened volunteer subjects agreed to take part in this research study. These volunteer
subjects were examined to assess the caloric burn effects of utilizing an exercise trainer device
with associated video workouts known as the Fast Fists by Nexersys vs. a standard treadmill
workout.
Testing protocol was approved and administered by Dr. Bob Girandola Ed.D, a Department of
Kinesiology Associate Professor at the University of Southern California, and Eddie Gaut,
Director of Research at the DETUAG Testing Centers.
Fifteen subjects were prepared for the metabolic measurement test (V02). Subjects were
connected to the Fitness Assessment System (FAS) while using the Fast Fists by Nexersys
system and while using a motor driven treadmill. The subjects exercised until their Anaerobic
Threshold was achieved.
In one condition the test subjects were familiar with the treadmill exercise and proper technique.
In a second condition they were first time users interacting with the Fast Fists by Nexersys
device and performing exercises depicted in the Fast Fists by Nexersys Cardio workouts. A 20
minute recuperation period was scheduled in-between the two tests.
This study evidenced a Fast Fists by Nexersys workout peak burn rate of 1512 calories an hour
or 252 kcal for 10 minutes while the treadmill workout for the same individual registered 358
kcal an hour or 59.7 kcal per 10 minutes indicating the Fast Fists by Nexersys workout was able
to generate over 4 times the calorie burn rate produced from the tested treadmill workout.

INTRODUCTION
Having a personal trainer or knowing someone who does has increasingly become part of the
societal norm. Personal trainers are in the news and on television. We are bombarded by the
benefits of having one in places like magazines and even with number one reality television
shows. Coincidently, as the popularity of personal trainers grows, so does the popularity of
mixed martial arts and boxing. The claimed benefits have made many curious of the importance
of boxing type workouts however, most need proper instruction and feedback and for the trainer
to be interactive so as to learn proper technique. Many of those curious about boxing styled
workouts and or personal trainers are concerned with their appearance and or health and are
especially interested in fun and challenging ways to efficiently and effectively maximize caloric
burn and muscle activity without having to go to a gym or fit into a personal trainer’s schedule.
In addition, for many, time is not something they can afford to waste on inefficient workouts or
ineffective exercise programs. Efficiently and effectively maximizing per minute calorie burn is
highly important and valued by many.
The market place is devoid of a physically interactive easy-to-follow, motivating and effective
device and program that acts as a personal trainer standing in front of you in order to maximize
core muscle tone while maximizing an individual’s calorie burning efficiency. Hence, there is a
need for a product of which a person can turn on and physically interact with that will promote
increased caloric burn more efficiently and effectively while teaching proper technique without
prescriptive side effects and without largely changing daily routines.
The Manufacturer states: ‘It provides a full body workout on a single fitness machine including
cardio, core and strike training rounds. Fast Fists by Nexersys is more than a punching bag,
offering over 100 professional videos that guide and direct you through cardio, core, striking,
technique and gaming rounds. Offering beginning, intermediate and advanced levels, Fast Fists
by Nexersys provides a great fitness solution for all, including those looking for a new fun,
family fitness option to the most advanced athlete.”
Detuag Testing, Inc conducted a Research Study for Brand Developers Ltd. designed to
document a user’s rate of caloric burn while performing a Fast Fists by Nexersys workout and a
treadmill workout. The results of this study will help Brand Developers Ltd. document
effectiveness of the product and be used to substantiate advertising claims.

As can be noted above, the group represented a broad spectrum of ages and fitness levels, with
ages ranging from 26 years to 54 years, and fitness levels ranging from low to superior. BMI
ranged from 20.8 to a high of 39.2. The National Institute of Health defines overweight as having
a Body Mass Index of 25 to 29 and obese as 30 or more. The above characteristics indicate the
group mostly represented normal and overweight.
Equipment
For Metabolic measurements a KORR Medical Technologies VO2 Fitness Assessment System
Model 9001 RMR (FAS) was used in conjunction with a wireless heart rate monitor and a Hans
Rudolph full face respiratory mask. A ProForm 795 SL Treadmill was used for the treadmill
portion of the test.
The FAS used in this study also measures the heart rate observed during an exercise test. Heart
rate monitoring during a metabolic test defines the unique relationship between heart rate and
calorie consumption for the tested individual.
Since the amount of calories expended is directly proportional to the amount of oxygen
consumed. The FAS used in this study calculates oxygen consumption by measuring the volume
of air that is exhaled and the concentration of oxygen in that air. The concentration of oxygen in
the inspired air is fairly constant. The FAS used in this study measures this inspired (room) air
oxygen concentration during an automatic calibration cycle prior to each test. This ensures
accuracy of the measurement. The FAS used in this study also measures the temperature,
relative humidity and barometric pressure to further improve the accuracy of the calculations.
To measure oxygen consumption, all of the air exhaled by the user must pass through the FAS
used in this study. Two (2) one-way valves are configured in or near a mask or mouthpiece.
This ensures that fresh air is inhaled and all exhaled gas passes through the hose and into the
FAS used in this study.
The amount of calories expended for a given amount of oxygen consumed is approximately 5
calories (0.005 Kcal) for every milliliter of oxygen consumed.
Because the volume of oxygen changes depending on the barometric pressure (elevation above
sea level) and the room temperature where the measurement is made, it is necessary to convert
all measurements to a standard temperature and pressure. This standard pressure and
temperature is called STPD, (Standard Temperature and Pressure Dry). The FAS used in this
study measures barometric pressure, relative humidity and temperature during each automatic
calibration cycle. Using these measured parameters, VO2 and metabolic rate measurements are
all compensated to standard (STPD) conditions.
Procedures
15 test subjects representing a wide range of fitness levels and first time users of the Fast Fists by
Nexersys volunteered to participate in the study. On test day they were weighed and measured
and the testing process was explained. Subjects were fitted with a heart rate monitor and a face
mask and an air tight seal was confirmed. Subjects were instructed to begin utilizing one of the
tested exercise machine workouts. A twenty minute break was given in-between each testing.

RESULTS
Caloric Burn Results
Table 2 displays the individual Peak and maintainable Anaerobic Threshold (AT) exercise level
and the calories burned per individual at the maintainable level. The Anaerobic Threshold (AT)
represents the maximum intensity level that an individual can maintain for an extended period of
time. The average AT values of all 15 tested subjects indicate that a treadmill workout at a 3 mile
per hour pace on level surface generated an average of 3 times less (2.97) of a caloric cost than
when utilizing the Fast Fists by Nexersys for the first time.

With the Fast Fists by Nexersys, one subject registered a peak caloric burn rate of 1512 kcal per
hour indicating up to 1512 kcal hr. could be burned or 252 calories every ten minutes. This
individual peak burn rate is 4.8 times the average treadmill peak rate of all 15 test subjects and
4.2 times more than when compared to their own treadmill result.
When we look at the more realistic sustainable AT burn rate numbers for the same individual we
find that the Fast Fists by Nexersys burn rate was 4.5 times more when compared to that same
individuals calculated treadmill workout AT level and 5 times more when compared to the
overall average of the 15 test subjects. In addition, with Fast Fists by Nexersys another test
subject registered 5 times more caloric expenditure when compared to their own treadmill AT
values.
7
Looking at it a different way, the AT expenditure of a tested subject on the treadmill was 55.3
Calories every 10 minutes. Thus, that individual would have to maintain the tested treadmill
workout pace for nearly 45 minutes to equal the 247.2 kcal. the same person expended in 10
minutes with Fast Fists by Nexersys.
To lose one pound of fat, which is calorically equal to 3500 Calories, using the maintainable
results (AT), on average, the 15 tested subjects would have to use the treadmill for 11.98 hours at
the tested pace and incline. Using the tested Fast Fists by Nexersys (866.8 Calories/hour AT) a
subject would only need to maintain that routine for approximately 4.0 hours to burn 3500
calories.
STATISTICS FOR CALORIE EXPENDITSURE
Comparing the values for Caloric Expenditure using the treadmill as compared to the Fast Fists
by Nexersys activity shows a major advantage when using the latter. Typically the treadmill is
considered to be the primary means of “burning” calories. Thus, any activity that compares
favorably to or EXCEEDS those values is considered efficient and effective. What the statistics
show (T Test) is that the differences that were found were significant. Statistics is the method of
showing that the differences found would be the same if another group of subjects were tested.
Normally, what is accepted in comparing exercise equipment or programs is P < 0.05 (95 out of
100) or P < 0.01 (99 out of 100). Meaning that 99 times out of 100 we would obtain the same
results with any other small group of subjects. In this study we found statistical significance at P
< 0.001 (999 out of 1000).
DISCUSSION
It is important to note that not all the moves associated with the Fast Fists by Nexersys cardio
programs were able to be followed as the testing equipment – specifically the face mask and hose
- did limit the movements the subject could perform. For instance, the up and down movement
of burpees could not be incorporated into the testing as the face mask and hose would disconnect
when that movement was performed. It is this researchers opinion that the results achieved
during the testing of the Fast Fists by Nexersys system are lower than what would actually be
achieved by following all of the moves via the cardio videos and could be considered an
impressive low end possibility of the caloric burn potential when not encumbered by a massive
hose connected to a full face mask and therefor limiting full movements and exertion levels. In
addition, these were first time users so one would expect that some better familiarity with the
device and technique would warrant even more efficient calorie burning during a Fast Fists by
Nexersys workout.
CONCLUSIONS
Caloric Burn
The results of this study demonstrated a workout with Fast Fists by Nexersys can produce up to 5
times more calories burned when compared to the tested treadmill workout.
An impressive Fast Fists by Nexersys peak caloric expenditure of 1512 was documented in this
8
study evidencing that up to 1512 kcal per hour is possible however what is most impressive is
the average of all 15 test subjects resulted in a 3 times higher documented burn rate at the
sustainable AT level. Therefore, on average, a Fast Fists by Nexersys user could realistically
burn up to 3 times or more calories than the tested treadmill workout.
No matter how you look at the numbers of this study the tested Fast Fists by Nexersys workout
comes out as the more efficient and effective way to burn calories. In fact, when looking at
either the peak caloric burn numbers or the more sustainable AT numbers, 7 of the 15 test
subjects or 47% individually registered a 3 to 5 times higher burn rate with Fast Fists by
Nexersys.
Statistical Analysis of the results tells us that an overwhelming majority of first time users could
expect the same result as generated in this study.
One other consideration for the Fast Fists by Nexersys is the concept of NOVELTY. Many
people don’t really enjoy “boring” exercises and will do almost anything to avoid them. That is
why there are so many different devices on the market. Therefore, the novelty of this device
would maintain attention span as well as provide a good caloric expenditure.

Abstract
Fourteen screened volunteer subjects agreed to take part in this muscle
activity research study. These volunteer subjects were examined to assess
the muscle activity effects of utilizing an exercise device known as Fast Fists
by Nexersys vs. a motorized treadmill workout.
Testing protocol was approved and administered by Dr. Bob Girandola
Ed.D, a Department of Kinesiology Associate Professor at the University of
Southern California, and Eddie Gaut, Director of Research at the DETUAG
Testing Centers.
14 subjects were tested for the EMG activity from the right Rectus
Abdominis muscle area and right external oblique while performing a
workout with the Fast Fists by Nexersys and compared to a workout
utilizing a motorized treadmill.
Surface electrodes, used to collect the muscle activity signals, were placed
on the targeted muscle area.
Subjects were instructed to perform the exercises for approximately 10
minutes. A one minute sampling of the workout was used for the tests. The
subject was not aware of when this sample would be taken during the 10
minute period. Subjects performed each workout with a twenty minute rest
period in between.
Statistical Analysis demonstrated a Fast Fists by Nexersys workout to be for
more efficient and effective than the tested treadmill workout.

Objectives:
The key objectives of this study were to:
1) Capture Electromyography (EMG) readings as it relates to muscle activity during
the tested workouts to be compared.
2) Find Statistical significance if any.
METHODS
Study Methodology
Testing protocol was approved and administered by Dr. Bob Girandola Ed.D, a
Department of Kinesiology Associate Professor at the University of Southern California,
and Eddie Gaut, Director of Research at the DETUAG Testing Centers.
14 subjects were fitted with surface electrodes on the top right side of the Rectus
Abdominis (RA) muscle and the right External Oblique area (EO) and examined EMG
activity while using the Fast Fists by Nexersys and while exercising on a treadmill.
Subjects were instructed to watch a brief cardio workout video for proper Fast Fists by
Nexersys use and to perform the workout. Subjects performed each workout for ten
minutes with a 20 minute rest period in between.
The Fast Fists by Nexersys workout was compared to a motorized treadmill workout, a
commonly accepted cardio machine. The individual peak and mean data are listed in
Table 2. The primary comparison of EMG activity can be seen under the mV/RMS
column (Root mean square of EMG activity).
Equipment
For EMG measurements (muscle activity measurements) a BTS POCKETEMG
instrument was used. The POCKETEMG is used in labs that study muscular activity in
the fields of rehabilitation, sports medicine, ergonomics, clinical research, in the studies
for the evaluation of functional abilities and muscular fatigue. The BTS POCKETEMG
was used in conjunction with Myolab software specifically developed for EMG signal
acquisition, visualization, and a first level of processing.
TEST DATA
Muscle Activity Results from the Research Study:
Table 2 displays the individual Peak and Mean values for the Root Mean Square (RMS).
Using the values for the RMS, there was a statistically significant difference between
working out with the Fast Fists by Nexersys and a treadmill workout. The mean data is
4
listed in the accompanying table. The primary comparison of EMG activity can be seen
under the Mv/RMS column. This indicates that, for almost all individuals, performing a
workout with the Fast Fists by Nexersys will activate more Rectus Abdominis muscle
and external oblique muscle better than the tested treadmill workout.
In comparing the Fast Fists by Nexersys workout to the treadmill it is obvious that the
mean (average) values are higher than the treadmill.
In comparing the mean data for the RMS column for Fast Fists by Nexersys vs.
Treadmill, the values are higher for the Fast Fists by Nexersys. These values are
statistically significant, for Rectus Abdominis P = 0.001 (vs. treadmill) and for External
Oblique P = 0.001 (vs. treadmill). To achieve statistical significance, P value must be less
than or equal to, 0.05.

The RMS is the preferred value for this type of study because it provides a measure of the power of the
signal (degree of activity). RMS represents the square root of the average power of the EMG signal for a
given period of time
As Table 2 indicates the Fast Fists by Nexersys workout proved to be much more
effective at generating core muscle activity than the treadmill workout. In fact, when
comparing the Peak activity numbers the Fast Fists by Nexersys workout proved itself to
5
be more than 6 times as effective as a treadmill when looking at the Rectus Abdominis
Peak numbers. In addition the Fast Fists by Nexersys workout generated more than 8
times the average Peak External Oblique activity than the tested treadmill workout.
STATISTICS FOR EMG
Comparing the values for EMG activity using the treadmill as compared to the Fast Fists
by Nexersys activity shows a major advantage when using the latter. Typically the
treadmill is considered to be the primary means of “burning” calories. Thus, any activity
that compares favorably to or EXCEEDS those values is really excellent. What the
statistics show (T Test) is that the differences that were found were significant. Statistics
is the method of showing that the differences found would be the same if another group
of subjects were tested.
Normally, what is accepted in comparing exercise equipment or programs is P < 0.05 (95
out of 100) or P < 0.01 (99 out of 100). Meaning that 95 times out of 100 we would
obtain the same results with any other small group of subjects. We found statistical
significance at P < 0.001 (999 out of 1000).

CONCLUSIONS:
Muscle Activity
The data revealed the Mean for the RA and EO muscles while using the Fast Fists by
Nexersys was more than 3 times the activity of the tested workout. As, in fact, there was
a statistically significant difference in favor of the Fast Fists by Nexersys workout per the
muscle activity testing (EMG) when comparing use of a motorized treadmill workout.

In addition, the average of the Peak data revealed 8.53 times more EO activity and 6.03
times more for the RA.
A core finding of this study is a Fast Fists by Nexersys workout resulted in higher muscle
activity levels when compared to the workout on the motorized treadmill.
Working out with the Fast Fists by Nexersys does provide more abdominal muscle
activity than a workout on a motorized treadmill.
An exercise device enabling a user to enhancing, even slightly, heart rate and weight
bearing activity has demonstrated to be efficient at producing improvement in muscle
tone and fat loss. Based upon such research,
One other consideration for the Fast Fists by Nexersys system is the concept of
NOVELTY. Many people don’t really enjoy “boring” exercises and will do almost
anything to avoid them. That is why there are so many different devices on the market.
Therefore, the novelty of this system would maintain attention span as well as providing
an effective and efficient core workout. Combining the tested Fast Fists by Nexersys and
associated workout with regular use we would anticipate, over the long term, for product
use to efficiently and effectively provide beneficial improvements in total body
appearance, core strength, loss in pant and dress size, as well as increased body strength.
