Abstract
The aim of this study is to investigate anaerobic power changes of the wrestlers who are performing
AMRAP (As many reps or rounds as possible) and Classic Crossfit trainings. The research has been
conducted on thirty-two male wrestlers who are challenging in first league of Turkish Wrestling in the
season of 2018-2019. The volunteer participants in test groups during eight weeks preseason in preparation
stage; Test Group I (Classic Crossfit) and Test Group II (Crossfit AMRAP) have performed Crossfit models
three times a week (Monday, Wednesday, Friday). They have participated in routine wrestling trainings in
between times (Tuesday, Thursday, Saturday). The data form has been given to identify the demographic
features of the participants. The support of specialist physician has been ensured during the implementation
of the programs. By creating a measuring parkour and after recording respectively body weight, height and
age, 6-30 sec anaerobic power test on wattbikepro has been implemented and it has been recorded on data
form. The measurements recorded on data form have been arranged on MS Excel spreadsheet program.
When identifying the differences between first and last measurements of anaerobic power values of the
participants, two factor variance analysis (two-way ANOVA for repeated measures) has been used in
repetitive measurements. As findings, when evaluating results obtained at the end of 8-week training
period, significant changes have been found in group X time interaction dimension in 6-30 sec anaerobic
absolute average power (watt) and anaerobic relative average power (watt/kg) values in classic Crossfit
training group (p<0,05). According to simple effect test results, it has been seen a change in classic Crossfit
training group at the end of the process in 6 sec Anaerobic Absolute Average Power (watt), Anaerobic
Relative Average Power (watt/kg) and Anaerobic Absolute Peak Power (watt) values. On the other hand, an
interaction has been recorded in AMRAP Crossfit training group only in Anaerobic Absolute Peak Power
(watt) values. Consequently, even though it has been ensured that there is a change in a positive way in
anaerobic capacity in wrestlers in both Crossfit training models, it has been seen that the effect of classic
Crossfit trainings on the performance is more.

1. Introduction
Crossfit is a sport organization whose popularity is speeding up as a brand and training modality
throughout the World. We see that it is participated in more than 10.0000 sport organizations in more than
142 countries in 2014 [3]. This popularity is increasing day by day and it has been creating an individual
cultural structure by arranging yearly Crossfit games [1]. Because of the popularity and speed in spreading
culturally of Crossfit, Forbes Magazine has categorized it as sport organization which is the fastest growing
in America [15].
In Crossfit programs whose founder is Glassman, 10 basic bio motor skills required to be improved
are aimed. These skills; cardiovascular, capacity, power, strength, flexibility, endurance, speed, coordination,
agility, balance and hitting [12]. When examining the content of Crossfit programs, we can see that it consists
of functional movements performed in high intensity. Crossfit training programs typically include Olympic
liftings, power liftings (squat, deadlift, bench press etc.) and gymnastic movements [24]. Exercise programs
called “Work of Day (WOD)” with these movements have been created and these turn Crossfit into a flexible
structure [21]. Crossfit programs by general definition is creating a good alternative to High Intensity
Interval Training (HIIT) modality. Crossfit exercises are functional performances which are multi-junction
and including combined movements and because it is structured in high in intensity, resting times between
sets is either not or pretty short [26,11].
Crossfit exercises is very close to High Intensity Functional Training (HIFT) working principle. The
principle of “Functional Training” is aiming a multifaceted improvement close to real movements and far
from isolated [5]. Crossfit combines it with high intensity and short intervals [10]. Another important reason
International Journal of Applied Exercise Physiology www.ijaep.com VOL. 9 (9)
74
of the popularity of Crossfit is that it includes less risk of injury compared to most of the traditional training
[10].
Crossfit has a flexible structure with training models and methods. Today, AMRAP (As many reps or
rounds as possible) method is a commonly used method which is also used in Crossfit Games [18]. In this
method, the aim is to perform required movement routines as much as possible for a length of time [9]. This
method is also aiming to push physiologic limits of the sportsmen by forcing working capacity along with
the fatigue [25].
When we look at the sportive performance, we can easily see that aerobic and anaerobic capacities
are some of the most important parameters for sportsmen to reach the success [17]. Crossfit training models
target aerobic and anaerobic capacity within together [20]. Aerobic capacity can be defined as oxygen which
can be used in society. While anaerobic capacity is the ability to adapt in maximal and minimal sub Works,
anaerobic power is on the other hand a response to anaerobic capacity of the work performed in unit of time
[27]. Crossfit exercises continue in high intensity and have short resting times. For this reason, it has to use
all energy systems and thus it is known that it improves not only aerobic but also anaerobic capacity and
power [13]. In terms of the difficulty, performing time and movements included of Crossfit exercises, it has
been seen that anaerobic power is important for sportsmen to be successful [14].
2. Method
32 healthy male wrestler taking part actively for five years and challenging in Turkish Wrestling First
League in the season of 2018-2019 have participated in our study. While (n=16) age average values of the
wrestlers are 20.8 ± 1.15 year and their height values are 175.2± 5.03 cm in Test-I (Classic Crossfit Training)
group, (n=16) age average values of the wrestlers are 20.93 ± 1.06 year and their height values are 176.5 ± 1.4
cm in Test-II (Crossfit AMRAP; As many reps or rounds as possible). The volunteer participants in Test
groups as Test-I (Classic Crossfit) and Test -II (Crossfit AMRAP; As many reps or rounds as possible) have
performed Crossfit models in preseason preparation period for 8 weeks and three times a week (Monday,
Wednesday, Friday). They have participated in routine wrestling trainings in rest of the days (Tuesday,
Thursday, Saturday). Verbal and written explanations related to the research to be conducted and the
measurements to be made have been made to the individuals participated in the study. The individuals
accepted to participate into the study have been ensured to fill “Volunteer Consent Form”. Each subject has
performed a gradual standard warming for 15 minutes before the test. All tests have been conducted on the
same day and have been observed and recorded by same researchers. Age, height and body weight of the
volunteer participants have been identified.
Height and Body Weight: Body heights of the participants have been adjusted with Holtain brand
slippery caliper while they are standing upright position and touching the heads of slippery caliper on the
scale and height has been read with 1 mm precision. Their body weight has been measured on Angel brand
scale which has 0,01 kg precision. The measurement has been made when the participant with the position
while the body weight on both feet even and standing on the scale and it has been recorded in terms of kg
[22].
30 sec and 6 sec Anaerobic Power Test: It is to pedal with highest speed as much as possible for 30
seconds against a certain outer resistance with wattbike pro anaerobic power. After volunteer participants
have been informed about the test before starting it, the participants have been ensured to have a position
according to seat height of wattbike with cambered knee joint (about 5 °) when they pedal at the same time
with leg scratching (Wattbike Pro, Wattbike, Nottingham, England). Air and magnetic resistances are used
in terms of increasing the resistance for the participants during the test on wattbike pro. To warm up, a
warming time for 3 minutes has been given to the participants by adjusting air and magnetic resistance as 1.
Body weight for resistance adjustments to be conducted on participants has been recorded to 30 sec test
program. Air and magnetic resistance adjustments have been implemented with the test program according
to the body weight of each participant. While the resistance has been designed according to program
specifications, it has been done in terms of representing equal work load with a percent of 7.5 of the body
weight. After the resistance has been adjusted specially for the participant on wattbike pro, the test has been
started on the condition of high speed turns as much as possible in 30 seconds. The participants have been
motivated verbally during the test. The information related to power parameters during the test has been
transferred to the program on wattbike 30’pro. All power parameters have been calculated by software

75
program. After the test is completed, the instruction to continue to pedal against 1 magnetic resistance and
air against cooling has been given to the participants. The participants have been given 3-5 minutes for
cooling down [23,7]
When identifying 6 sec anaerobic power capacity, all protocols defined above have been implemented
exactly and the test has been conducted by ensuring the participant to perform with the highest level for 5 6
sec on wattbike pro. 6 sec anaerobic power and 30 sec anaerobic power tests have been conducted on the
participants on different days. The participants have been provided to rest between those two measurements
[28].
2.1.Training Protocol
Test-I (Crossfit AMRAP; As many reps or rounds as possible) and Test II (Classic Crossfit) groups
have performed Crossfit models 3 days in a week (Monday, Wednesday, Friday) for 8 weeks. Additionally,
the participants have performed 3 days in a week (Tuesday, Thursday, Saturday) for 8 weeks with the
condition of scope and violence in parallel.

4. Discussion and Conclusion
The aim of this study is to identify the effect level of classic Crossfit training and Crossfit AMRAP
training on anaerobic power. When we look at the effect of training models applied for 8 weeks on anaerobic
power development, the quantitative development in Absolute Average Power and Anaerobic Relative
Average Power values of classic Crossfit training group is found statistically significant compared to the
development in Crossfit AMRAP training group according to Watt Bike anaerobic test results conducted for
30 and 6 seconds. Considering refereed journal and journals in the index, there is a limited literature
possibility on performance parameters.
When examining the pre and final measurements of the groups, the quantitative development has
been found statistically significant only in 30 seconds Watt Bike test in Crossfit AMRAP training group.
While the development in Anaerobic Absolute Average Power and Anaerobic Relative Average Power
values of regular Crossfit training group has been found significant in 30- and 6-seconds Watt-Bike test,
Anaerobic Absolute Peak Power has been found significant only in 6 seconds Watt-Bike test.
Dexheimer et al. in their study have identified that Crossfit has enhanced the relation of “fran”,
“grace” and nancy models with anaerobic power performance and they have also stated that only nancy
models have significant relation with anaerobic power [8].
Timon et al. in their study have examined biochemical parameters and recovery after Crossfit training
model in different type. In this study, AMRAP and RFR (rounds for time) method within work of the day
have been compared. At the end of this study, there is more increase in RFR model, lactic amount, difficulty
level perceived (RPE), Maximum heart beat number and average compared to AMRAP model. Especially in
high heart beat numbers endurance time is more in RFT model. While RFT is more intensive model as
violence, AMRAP can be considered to develop to work in higher masses. It can be stated that the findings
of our study are supported in terms of the parameters that this study has examined [25].
Bellar et al. in their study have stated that the difference in peak power value of the sportsmen
(806.5±129.4 w) who have not participated in any competition before and experienced sportsmen
(864.8±154.8 w) who have performed actively and participated in competitions is not statistically significant.

In addition to that, they have identified that experienced group has achieved more reps in a significant way
in AMRAP exercises and completed reps in 21-15-9 workout exercises in shorter time in a significant way.
Also, it has been cited that Crossfit performance is related with aerobic capacity and anaerobic power of the
individual [4,17].
Martínez et al. in their measurements that they have conducted on the sportsmen whose age average
is 36±9 and participated in Crossfit competitions, have stated that body weight of high-performance group
(HP) is 78±2 and body weight of the sportsmen who have shown low performance (LP) is 84±11. It has been
noted that the performances of HP group are significantly higher in squat jump test results. Also, it has been
reported that the difference between average power values (HP;671 ± 39, LP;639 ± 70 w) and peak power
(HP;823 ± 58, LP;788 ± 86 w) values has not been found significant [14].
Bellar has cited that aerobic capacity and anaerobic power with the experience and age has affected
Crossfit performance [4]. Butcher et al. have defined that grace and fran performances of the sportsmen
participated in 4th Crossfit Open are related with anaerobic threshold [6]. Goins et al. have stated that they
have observed a significant development in some strength values and anaerobic capacity values in 6 weeks
in their study which they have examined the effects of 6-week Crossfit training on some physical and
physiologic variables [13]. Schafer et al. have reported that the increase in vertical jump, anaerobic power
and peak power values in first grade college students who have 18 age average and performed ROTC
training with Crossfit for 12 weeks has not shown significance [19]. Most of the studies in literature have
shown that Crossfit training is effective on anaerobic power development. One study has noted that it has
not provided an increase in anaerobic power values [19].
As a consequence, while the quantitative increase in performance values of AMRAP Crossfit training
group after 8-week training has not been found statistically significant, the alteration in classic Crossfit
training has been found effective. It has been seen that AMRAP Crossfit training is effective only on peak
power. The effective resistance coefficient which can be performed during the implementation of the
movement in AMRAP model has been decreasing the quality of output against resistances. At the same time,
it has been causing injury risks. The criteria to participate in Crossfit trainings should be implemented by
identifying effectively by the trainers. It has been seen that the design of classic crossfit training model is
more distinct in reflecting to the wrestlers. However, it should be noted that the wrestlers to be trained
actively involve in either Greco-Roman or freestyle.
