Abstract

The purpose of this study was to investigate the relationship between anaerobic power and vertical jump performance in adolescent athletes. Twenty four track and field athletes participated in this study (mean age: 15.79±0.83 years; height: 166.78±9.77 cm; weight: 57.44±13.42 kg; BMI: 20.45±3.01 kg/m2; body fat percentage (%): 18.80±5.55). The 12 minute Cooper test was performed to estimate VO2max (41.73±6.92 ml/kg.min). After 3-7 days the subjects applied counter movement jump (CMJ) and squat jump (SJ) for the following parameters: (1) the maximum jumping height [SJh and CMJh], (2) the total work produced by the body in each jumping condition [SJw and CMJw: weight (kg) x jump height (m)] and (3) the anaerobic performance [CMJpower and SJpower (kg.m/s): P= √4.9 x weight (kg) x √jump height (m)]. The Wingate anaerobic test was applied to determine peak power, average power and fatigue index. The jumping performance variables (height, total work and anaerobic power) and VO2max did not relate significantly to the fatigue index (p> 0.05). All jump performance variables had a significant relationship with peak power and mean power (p<0.05 and p<0.01). Although both the absolute and relative Wingate test variables were significantly correlated with all jump performance variables, the r values for the relative variables were lower than their absolute counterparts. The results of the present study indicated that in field conditions the trainers may predict anaerobic performance using the jumping properties and when the subjects’ body weight was incorporated, this led to a more representative indicator of the subjects jumping abilities.

Introduction
Track and field is a sport performed indoors or outdoors and made up of various competitive athletic
contests based on running, hurdling, jumping (the high jump, the long jump, the triple jump), vaulting (the pole
vault), walking events and throwing varied weights and objects (shot put, hammer throw, discus throw and
javelin throw). Additionally, there are composite events as decathlon, heptathlon or pentathlon. Therefore the
strength and anaerobic power are the basic motoric abilities that determine the sports performance. The ability of
generating significant amounts of power is considered to be a strong predictor of athletic success (Bompa, 1993).
In shorter activities the patterns like jumping, throwing or striking the muscle strength, and particularly
the ability to produce it fast plays a major role (Bencke et al., 2002). One of the most important matters in
modern sports is evaluation of the athletes’ physical capacities; for this reason many tests are used for selection
procedures, for screening candidates, or to monitor the efficacy of training systems (Norkowski, 2002). The most
common field tests used to evaluate the anaerobic power and performance in athletes are the vertical jump tests
(Brooks et al., 2000). The vertical jump tests are used as a laboratory or field functional tests to measure power
output of the legs (Malliou et al., 2003) and it is considered to be a component of performance because of its
involvement in the activities of various explosive sports (track and field events, volleyball and weight lifting)
(Tsiokanos et al., 2002).
Anaerobic performance is composed of anaerobic power and capacity. The Wingate anaerobic power
test (WAnT) is a common dynamic test used to evaluate an athlete’s anaerobic performance. As a laboratory
measure, the WAnT is considered to be the most valid and reliable instrument to assess peak power (PP) and
anaerobic capacity (Inbar et al., 1996; Powers and Howley, 1996). It has been reported that there was a
significant correlation between PP and vertical jump height in athletes (r = 0.86) and in a group of mixed athletes
and non-athletes (r = 0.82) (Kasabalis et al., 2005).
Sports performance professionals and sports scientists have been focused on performance assessment;
however there are lacks of research examining the relationships between various motor skills (Vescovi and

McGuigan, 2008). While some studies have investigated the relationship between different physical performance
variables (anaerobic performance, vertical jump performance, sprinting ability etc.) an insufficient number of
studies have been conducted on track and field adolescent athletes. However the participation of children and
adolescents in competitive sports has increased recently. Knowledge of the power outputs and jumping height
would, therefore, be useful in terms of coaching, and it would be very vital in controlling the outcomes from the
training programs (Shalfawi et al., 2011). Thus, the purpose of this study was to investigate the relationship
between Wingate anaerobic test performance, vertical jump and aerobic performance in adolescent track and
field athletes.
Method
Participants
Twenty four amateur track and field young athletes (n= 13 males, age: 15.92 ± 0.64 years; n=11
females; age: 15.63 ± 1.02 years; runners, jumpers and throwers) of boarding sports high school volunteered to
participate in this study. All participants were the member of the same team competing in the national league and
trained at least ninety minutes in a day for six days per week. Nobody of the participants had a history of major
lower limb injury and disease. At the beginning of the study all participants were informed about possible risks
and benefits of the study and written consents were obtained from them and from their parents or legal guardian.
The study was approved by the local ethical committee and was conducted in accordance with the Helsinki
Declaration.
Procedures
The study was conducted in two parts over a week period. Anthropometric data collection and evolution
of maximal oxygen uptake (VO
2
max) were performed at the same day. After 3-7 days, vertical jump and
Wingate anaerobic power test (WAnT) were performed giving sufficient recovery time between tests. All
participants were instructed to avoid from strenuous exercise for the 48h period before the tests (Bloomer et al.,
2005).
Measurements
Participants’ heights were measured using a stadiometer (Holtain, Britain) to the nearest 0.1 cm,
additionally participants’ weights, BMI (kg/m
2
) and percent body fat (%) were estimated by bioelectrical
impedance analyzer (Tanita MC-180-MA, Japan). All measurements were performed in duplicate with the
average value used as the criterion. After collecting the anthropometric data, a 12 minute walk/run test (Cooper)
was used as an indirect method to predict VO
2
max. The results were determined by multiplying the number of
tours and the distance of each tour (400 m) and adding the distance of the completed tour (meter). The VO
2
max
values were determined using the Balke formula (1961).
VO
2
ml/kg.min = 33.3 + (distance covered/12 – 150) x 0.178 ml/kg.min
Three to seven days following the VO
2
max evaluation the participants came to the laboratory in the
morning (10.00 am) for the second part of the study. After 10-15 min (Bloomer et al., 2005) of rest in sitting
position systolic blood pressure (SBP), diastolic blood pressure (DBP) and resting heart rate (HR) were
measured on the upper arm according to the manuscript, using sphygmomanometer (Microlife BP A100,
Switzerland).
First of all participants started with a standardized warm-up of 5-7 minute of cycling at 55-60 rpm
against no load (894 Ea, Peak Bike by Monark AB, Sweden) and 5-7 minute of stretching. Following the warm-
up, participants rested for 5-min. All jumps were performed using a dedicated force platform (Sport Expert TM,
MPS-501, Tumer Electronic LDT, Turkey). After a familiarization session (learning the proper techniques of the
two jump conditions) each subject performed three maximal voluntary vertical jumps at each of two testing
conditions - Squat Jump (SJ) and Counter Movement Jump (CMJ); and the best value of the three trials were
used for further analyses.
The SJ was performed from a starting position with the subjects’ knees flexed to 90
0
, hands fixed on the
hips and with no allowance for preparatory counter-movement. The CMJ was performed from an upright
standing position, with the hands fixed on the hips and with a counter movement preparatory phase ended at a
position corresponded to the starting position in SJ. Sufficient recovery time was given among trials (more than
2 minutes). For the SJ and CMJ, three parameters were estimated (Çakır-Atabek et al., 2009): (1) the maximum
jumping height (SJh and CMJh), (2) the total work produced by the body in each jumping condition (SJw and
CMJw) which was calculated according to Genuario and Dolgener formula (1980) and (3) the power output
(SJpower and CMJpower) value which was determined using the following formula (Roger, 1990).
SJ
power
and CMJ
power
(kg.m/s) = √4.9 x body weight (kg) x √jump height (m)
The WAnT was conducted using a mechanically braked cycle ergometer (894 Ea, Peak Bike by Monark
AB, Sweden). Participants were seated on the ergometer and adjustments to the ergometer were made to ensure
an optimal cycling position. Seat height was adjusted to each participant’s satisfaction, and toe clips with straps
were used to prevent the feet from slipping of the pedals. The WAnT was conducted according to widely
accepted recommendations for standardization (Inbar et al., 1996). The WAnT was administered for 30 seconds

and the resistance was set at 7.5% of body mass. Participants were encouraged to pedal as fast as they could
prior to the application of resistance. Following application of resistance the participants continued pedaling at
maximum speed throughout the remaining 30s. Verbal encouragement was provided by the investigator.
Absolute peak power (APP), relative peak power (RPP), absolute mean power (AMP), relative mean power
(RMP) and minimum power were calculated automatically by the WAnT program via computer (Monark
Exercise AB, Sweden) and were recorded for further analysis. A fatigue index (FI) was calculated by using the
following equation (Inbar et al., 1996).
Fatigue Index (FI) = [(Peak Power Output - Minimum Power Output) / Peak Power Output] x 100
Statistical analysis
All values were presented as mean ± standard deviation. Before parametric analyses were done, the
normality of distribution of the data was assessed with Kolmogorov–Smirnov test. Then, the correlations
between Wingate anaerobic test variables (APP, RPP, AMP, RMP, and FI), jump performance variables (SJh,
CMJh, SJw, CMJw, SJpower and CMJpower) and VO
2
max was evaluated using the Pearson Product Moment
Correlation analysis. All analyses were executed using the SPSS for windows version 16.0 and statistical
significance was set at p < 0.05.
Results
Participants’ descriptive data are presented in Table 1. The squat jump (SJh, SJw and SJpower) and the
counter movement jump (CMJh, CMJw and CMJpower) values of the subjects are presented in Table 2,
moreover, the values of WAnT performance (APP, RPP, AMP, RMP, and FI (%)) of the subjects are presented

Table 4 presents the correlation coefficients among measured variables. For all examined variables, it
appears that the jump performance variables (height, total work and anaerobic power) and VO
2
max did not have
a significant relationship with the FI (%) (p > 0.05). Furthermore, the VO
2
max did not have a significant
relationship with load (kg), peak power and mean power expressed in watt (w: absolute values) (p>0.05), but it
had a significant relationship with peak power and mean power expressed in watt/weight (w/kg: relative values)
(p<0.05). In addition, all jump performance variables (height, total work and anaerobic power) had a significant
relationship with load (kg), peak power and mean power (p<0.05 and p<0.01). Although both the absolute and
relative WAnT variables (w and w/kg) were significantly correlated with SJw, CMJw, SJpower and CMJpower
performance variables the r values for the relative variables were lower than their absolute counterparts (Table
4).

Discussion
The relationship between vertical jump performance and WAnT performance was investigated in
amateur adolescent track and field athletes. The main findings of the current study show that there is a high
correlation between WAnT performance variables (APP, RPP, AMP, RMP) and all jump performance variables,
however, the r values for the relative variables were lower than their absolute counterparts.
Anaerobic performance is important for every type of sport activities. As it is known the sudden and
high intensity power production is required in times of sudden attack and press defense during the team games,
during the sprinting, during the throwing and jumping events and also in many other sports activities. Anaerobic
performance is composed of anaerobic power and capacity. Anaerobic power reflects the ability to use the
phosphagenic system and anaerobic capacity, reflects the ability to derive energy from a combination of
anaerobic glycolysis and the phosphagen system. Anaerobic performance depends on many factors, such as body
composition, age, sex, muscle fiber composition, muscle cross sectional area, strength and training (Kin-Đşler et
al., 2008). The dynamic and static contraction power of legs are closely related to anaerobic power performance
where it is an important criterion for the sport performance in sports involving explosive efforts (Fox et al.,
1993). In addition The Wingate anaerobic power test is a reliable and the most popular method for calculating
the anaerobic peak power of lower limb muscles (Inbar et al., 1996).
The relationships between various performance variables and fatigue index have been examined by few
studies (Alemdaroğlu, 2012; Saç and Taşmektepligil, 2011; Arslan, 2005). Fatigue index is one of the criteria
that assess an athlete’s ability to sustain high power outputs during exercise. It has been reported that in first
division basketball players there was no significant relationship between VO
2
max and FI; also, there was no
significant relationship between CMJh, SJh and FI (Alemdaroğlu, 2012). In another study it has been shown that
in well trained male athletes there was not significant relationship between anaerobic power, measured with the
vertical jump, and FI (Saç and Taşmektepligil, 2011). Additionally, in a group of trained and sedentary men and
women no correlation was seen between vertical jump values and FI (Arslan, 2005). In consistent with these
results, the findings of the current study indicated that the jump performance variables (height, total work and
anaerobic power) and VO
2
max did not significantly correlate with the FI in adolescent track and field athletes
(p>0.05). In a recent study by Alemdaroğlu (2012) it was shown that there was no significant relationship
between RPP, RMP and VO
2
max. Although, the results of the present study indicated that the VO
2
max did not
correlate with load (kg), APP and AMP (p>0.05), the VO
2
max
significantly correlated with RPP and RMP
(r=0.54; r=0.64, respectively; p<0.01). Lack of findings regarding the relationship between WAnT performance
and VO
2
max limits our discussion.
Mechanical power is an essential variable for the performance in sport and in the daily activities, and
has been studied by researches for a long time. SJ and CMJ are commonly used tests to measure athlete-jumping
ability. SJ is used as a measure of lower-body concentric strength/power, while CMJ as a measure of lower-body

reactive strength/power (Newton et al., 2006). The mentioned studies suggest the two tests, SJ and CMJ, are
valid and relevant measurement tools of athletic lower-body force and power ability (Riggs and Sheppard, 2009).
When performing different types of jumps, the central nervous system uses different motor programs to execute
the neuromuscular coordination necessary for the specific jumps. The SJ can be used as the most basic functional
expression of explosive muscle strength as it requires only concentric activation. The CMJ requires moderate
eccentric activation followed by high concentric activation, and therefore requires a more complex timing and
graduation of the motor units. Thus the SJ can serve as a baseline for the potential of explosive muscle strength
and CMJ may indicate development of this potential (Bencke et al., 2002).
The results of the present study indicated that all jump performance variables (height, total work and
anaerobic power) had a significant relationship with load (kg), PP and MP (p<0.05 and p<0.01; Table 4).
Stauffer et al. (2010) observed strong significant relationship (r=0.85) between peak power measured with the
vertical jump and the WAnT in the group of 13 females basketball players (age: 19.7±1.1 years). In a similar
study conducted by Farlinger et al. (2007) the r value of correlation between the vertical jump (height) and the
modified Wingate performance (APP, AMP, RPP and RMP) was reported to be between 0.63 and 0.69 in a
group of male competitive hockey players between the ages of 15 and 22 years (mean age: 16.3±1.7 years).
Besides this, it has been reported that the correlation between the peak power measured with the vertical jump
and the absolute Wingate performance (APP, AMP) were 0.88 and 0.89 respectively. On the other hand the
correlation between the peak power measured with the vertical jump and the relative Wingate performance
(RPP, RMP) were 0.46 and 0.33 respectively (Farlinger et al., 2007). In another study conducted by Arslan
(2005) it was reported that in the regular exercise group, which included men and women, there was a positive
correlation between APP, RPP, AMP, RMP and vertical jump performance (r=0.60, r=0.49, r=0.63, r=59,
respectively). In addition it has been indicated that there was significant relationship between APP, AMP and
vertical jump performance (r=0.68, r=0.65, respectively) in the sedentary group (Arslan, 2005). Moreover, it has
been determined that the WAnT-APP was significantly correlated to vertical jump height (r=0.56) in soccer
players aged of 19.6±0.8 years (Miller et al., 2011).
In another study conducted by Bencke et al. (2002) it has been observed that there was a weak
relationship between PP development and SJ and CMJ performance (r=0.41 and r=0.46, respectively) in a group
of children (boys and girls) aged between 10 – 13 years old, which were active in swimming, tennis, gymnastics
or handball. Similar to these results, it has been reported that in a group of male athletes competing at the
national and international level (volleyball, basketball, wrestling) there was a weak relationship between vertical
jump and PP (r=0.36) (Saç and Taşmektepligil, 2011). Moreover, it has been shown that there was a weak
relationship between AMP, RMP and vertical jump (r=0.35, r=0.43) (Almuzaini and Fleck, 2008).
In contrast to the mentioned studies above, it has been indicated that there was no relationship between
APP, RPP and vertical jump performance in a group of physical education student (age: 21.66±1.66 years)
(Almuzaini and Fleck, 2008). Besides this, no relationship was observed between CMJh and APP in adolescent
skiers (age: 14.6 ± 1.1 years for boys and 14.9 ± 1.0 years for girls) (Emeterio and González-Badillo, 2010).
Additionally, no significant relationship was observed between RPP, RMP and CMJh, no significant relationship
was observed between RPP and SJh in American football players (age: 23.07±3.45 years), only the SJh was
observed to be significantly related to RMP (r=0.536) (Eyuboğlu et al., 2009). Moreover, although it has been
determined that the relationship between CMJh, SJh and PP were significant, the relationship between CMJh and
MP was not significant (Alemdaroğlu, 2012).
Conclusion
In conclusion, there are two purposes for assessing athletic performance. First and most common is to
determine quantitative improvements made after a training cycle. This allows the athlete and sport performance
professional to examine if a training stimulus was sufficient to cause a positive adaptation. This method does not
however lead the professionals in the direction that they should focus the training on. Therefore a second
purpose of athletic assessment is to point out specific weaknesses in performance using various splits (Shalfawi
et al., 2011). It is known that the SJ and CMJ are typically used as indicators of lower body power and the results
indicated that vertical jump may predict the maximal anaerobic power and could be used by coaches as a
practical and easy-to-apply field screening test (Kasabalis et al., 2005). However, it has been suggested that
when the subjects’ body weight was incorporated, this led to a more representative indicator of the subjects
jumping abilities. It means that, with same jumping height a heavier subject will need greater extension strength
to overcome the higher external resistance during jumping (Çakır–Atabek et al., 2009).

... In addition, XP is considered by many authors as the "anaerobic capacity" and represents the average mechanical power maintained during the 30 s, taken at 1, 3 or 5 s periods [7]. Some authors have shown PP and XP to be associate with performance in some team and individual sports, especially those performed at high intensity or a combination of low-moderate intensities with higher intensity peaks such as CF [8], surfing [9], alpine ski [10], soccer [11], track and field athletes [12] and many others. ...
... In order to assess this ability out of the laboratory, numerous field tests, consisting of different exercises or tasks, have been created. Some of them based on different modalities of jumps [5,[12][13][14][15][16]; running [14,17,18]; squat exercise [14,19,20]; and other exercises such as skipping [21]. All those tests have been studied in active individuals [17,18,21,22] as well as athletes of different sports such as soccer [14], volleyball [5,15], track and field [7,12,20,23], and cyclists [24,25]. ...

Anaerobic power and capacity are considered determinants of performance and are usually assessed in athletes as a part of their physical capacities’ evaluation along the season. For that purpose, many field tests have been created. The main objective of this study was to analyze the agreement between four field tests and a laboratory test. Nineteen CrossFit® (CF) athletes were recruited for this study (28.63 ± 6.62 years) who had been practicing CF for at least one year. Tests performed were: (1) Anaerobic Squat Test at 60% of bodyweight (AST60); (2) Anaerobic Squat Test at 70% of bodyweight (AST70); (3) Repeated Jump Test (RJT); (4) Assault Bike Test (ABT); and (5) Wingate Anaerobic Test on a cycle ergometer (WG). All tests consisted of 30 s of max effort. The differences among methods were tested using a repeated-measures analysis of variance (ANOVA) and effect size. Agreement between methods was performed using Bland–Altman analysis. Analysis of agreement showed systematic bias in all field test PP values, which varied between -110.05 (AST60PP—WGPP) and 463.58 (ABTPP—WGPP), and a significant proportional error in ABTPP by rank correlation (p < 0.001). Repeated-measures ANOVA showed significant differences among PP values (F(1.76,31.59) = 130.61, p = < 0.001). In conclusion, since to our knowledge, this is the first study to analyze the agreement between various methods to estimate anaerobic power in CF athletes. Apart from ABT, all tests showed good agreement and can be used interchangeably in CF athletes. Our results suggest that AST and RJT are good alternatives for measuring the anaerobic power in CF athletes when access to a laboratory is not possible.
... The jumping ability was a popular topic of research in TAF. [21][22][23] Moresi et al 21 investigated the reliability of two long jump tasks (standing broad jump -SBJ -and reactive jump) and the possibility to predict 10m sprint time in elite TAF girls. They observed that these tests had good reliability and SBJ was a good predictor of 10m sprint time. ...
... Consequently, bilateral exercise programs may be adopted in the early training of TAF athletes to enhance jumping ability of the dominant take-off leg. The abovementioned studies [21][22][23] highlighted the importance of jumping ability in TAF and considered validity and reliability aspects of exercise testing. ...

The present study aimed to review the physiological aspects of adolescent track-and-field (TAF) athletes. A search of Scopus on 27/12/2022 using the syntax ABS (track-and-field) AND ABS (children) OR ABS (adolescent) showed 121 documents, and 45 were considered for further analysis. In addition, handsearching was conducted to identify Russian literature missing in Scopus. Differences were shown in performance characteristics among disciplines, especially between throwers and the other athletes. The sex difference in performance (ie, a better performance in boys than in girls) started in early adolescence. A relative age effect was more pronounced in athletes under 13 years old. Despite the wide use of nutritional supplements, an insufficient intake of vitamins has been found. The age of training onset and body weight were identified as risk factors for problems with menarche. The inclusion of track-and-field training programs in physical education was beneficial for health and physical fitness. The need to collaborate closely with parents and coaches was identified, especially, regarding education in topics such as the age of training onset, relative age effect, and doping. In conclusion, the existence of many disciplines with different anthropometric and physiological characteristics highlighted the need for a discipline-specific approach.
... A variety of methods exist to assess lower body power output in athletes. These include jumping, weightlifting, and cycle ergometry assessments (Çakir-Atabek, 2014;Carlock et al., 2004;Hoffman et al., 2000). Despite differences in testing methodologies, previous research has indicated performances on these assessments were highly correlated with each other. ...
... The authors found strong correlations between the estimated peak power from both static and countermovement jumps and weightlifting performance (r ≥ 0.90). Additionally, the vertical jump has been shown to be positively correlated with both mean and peak power outputs attained during Wingate testing (Çakir-Atabek, 2014;Hoffman et al., 2000). This suggests vertical jump assessments are a valid field test for evaluating lower body power output in athletes. ...

While force plate technology is the gold standard for assessment of many aspects of vertical jump performance, its cost is prohibitive to a broad spectrum of the population. Accelerometry may be more practical, inexpensive, and provide a simple solution that allows hands-on practitioners to readily assess vertical jump performance acutely and over time. Thus, the purpose of this study was to examine the accuracy of an experimental accelerometer for testing vertical jump heights derived from flight times when compared to a laboratory-based force plate system as a criterion measure. Fifteen subjects performed three sets of three nonconsecutive maximal countermovement vertical jumps while standing on the force plate. The accelerometer device sampling at 100 Hz was placed on the anterior abdomen immediately inferior to the umbilicus and secured with an elastic band. Both devices recorded the data simultaneously. The experimental accelerometer was an appropriate tool for the assessment of vertical jump height; however, it significantly overestimated actual vertical jump heights by an average of 3.1 cm. This consistent discrepancy in the measurement may be easily fixed by a simple algorithm correction and should not present an issue in the practical setting where ease of use and the ability to provide immediate feedback regarding an athlete’s performance is of critical importance.
... This larger power output in track and field athletes is related to both the demands of a powerful execution of the technique in the vast majority of the track and field disciplines and the sport-specific execution of the jumping exercises that is a characteristic in athletics training [13][14][15]. Nevertheless, performance in the vertical jump tests is not homogeneous among track and field athletes, as differences have been observed due to the discipline [11,16,17], the level of performance [18,19], the part of the training period within the season [20][21][22], sex [23,24] and age within adolescence [25]. The sex difference between male and female track and field athletes is enlarged during the progression of adolescence, since male athletes grow more than females in terms of body size, muscle mass, strength and power [26]. ...

Isokinetic metrics are suggested to be related to vertical jump performance, but little is known about the possible sex differences in this relationship in adolescent track and field athletes. The aim of the study was to examine the possible sex differences in the strength of the relationship between the kinetic parameters of the vertical squat jump with arms akimbo, the countermovement jump with arms akimbo, and the countermovement jump with free arm swing with the isokinetic parameters of the knee extensor and flexor muscles (angular velocities: 60°/s and 300°/s). In total, 35 (males: 21, females: 14) U18 track and field athletes were examined. The results revealed that the Men U18 group had higher vertical jump performance, higher values in the kinetic parameters of the vertical jump tests, higher knee extensor torque, and higher knee flexor torque in the non-dominant leg compared to the Women U18 group. Significant (p < 0.05) sex differences were observed in the relationship between the isokinetic parameters and the vertical jump performance metrics, as the Women U18 athletes relied more on the knee flexor torque than Men U18 athletes, and demonstrated a stronger negative relationship between selected isokinetic metrics and the pre-stretch gain in the vertical jump tests. In conclusion, it is recommended that young female track and field athletes minimize interlimb asymmetry and improve the convention ratio in their non-dominant leg to optimize vertical jump performance.
... In all test circumstances, specifically the Squat Jump and Counter Movement Jump, each participant performed a total of three leaps. The maximum recorded value from the three trials was chosen for later analysis (Atabek, 2014). ...

Road Cycling is an important sport that uses anaerobic and aerobic metabolism and especially sprinter cyclists have higher anaerobic capacity. The assessment of anaerobic power in cyclists often involves the use of the vertical jump and Wingate cycle tests. The lack of research in the field of cycling-specific tests to assess anaerobic performance has led to the improvement of existing research. The objective of this research was to investigate the correlation between the vertical jump test and the Wingate anaerobic cycling tests, both of which are often used to assess anaerobic power in road cyclists. A correlation study was conducted on 15 athletes of the Turkish national road cycling team in the 14-16 age group (15.107 ± 0.717 (SD)). The sample of the study was determined by using the convenient sampling method. On the first day, anthropometric measurements and the vertical jump test were conducted. The Wingate cycle ergometer test, lasting for a duration of 30 seconds, was administered to the participants on the second day. The computer application was used to determine the 30-second peak and average anaerobic power during the test. The results acquired from the study revealed a statistically significant positive relationship between the vertical jump performance and the peak power production measured during the Wingate cycle test (r=0.321, p<0.05). The findings indicate that vertical jump tests may serve as suitable field measurements of anaerobic power for road cyclists, as an alternative to the laboratory-based Wingate anaerobic test.
... Moreover, the protocols of VJ tests are easier to execute. A considerable number of analyses have shown that such tests do have a high level of informative value (Çakir-Atabek, 2014;Sellers, Schnaiter, & Smith, 2014). ...

The countermovement jump test (CMJ) is commonly used as an indicator of the anaerobic capacity of the lower limbs. The main objective of this study was to evaluate the relationship between the CMJ with arm swing and the Wingate anaerobic test (WAnT) among female volleyball and football players. A group of first league female volleyball club players (VG, n = 12, age = 24.2 years), a group of first league female football club players (FG, n = 12, age = 20.6 years), and a control group (CG, n = 10, age = 20.4 years) participated in this research. The measurements of selected somatic features were carried out. The CMJ and WAnT were used to assess the explosive strength and maximum muscle power of the lower extremities. An analysis of variance test demonstrated differences between the VG and FG in terms of height (p < .001), body weight (p < .001), and lean body mass (p < .001). In the FG and VG groups, correlations between CMJ and maximum anaerobic power as determined by WAnT were r = .82 and r = .57, respectively. There was not statistically significant differences between values of these coefficients. The obtained results showed a potentially lean body mass influence on the results of the CMJ in VG. In women’s football and volleyball, the results of the CMJ are strongly correlated with the power parameters registered with the WAnT. In volleyball, players’ coaches should include a measurement of lean body mass in the assessment peak power by vertical jump tests.

Background: The resistance exercises underpin the strength and power development of muscle activation in adolescent footballers. Objective: The study purposed to review the effectiveness of different resistance exercise models on improving anaerobic and balance characteristics among young football players. Methods: A systematic search of Scopus, SPORT Discus, and the Web of Science was undertaken to identify the study content using a combination of searches related to resistance exercise, balance, and anaerobic performance. Titles and abstracts were used to search for keywords, and data were extracted using the subject characteristics, training intervention, measurement, and outcomes. Results: Fourteen studies were identified that investigated the effects of resistance programs on the anaerobic and balance characteristics. A combination of plyometric and regular football training significantly improved the anaerobic characteristics, and balance performance in young footballers. Based on high-quality evidence, anaerobic and balance performance enhancement appears after conducting resistance exercises for approximately eight weeks, with two to three sessions on alternate days a week. The volume consists of 2-3 sets per exercise, 6-12 repetitions per set, and intensity was classified as moderate to high, with one repetition maximum. Conclusion, Integrating resistance exercise into the regular training sessions improves the anaerobic performance of young footballers, such as jumping, sprinting, and changing direction, while improving balance ability, indicated by reducing the center of pressure area side-asymmetry and sway speed during unipedal and bipedal leg stance.

The sports and culture sectors play a significant role in generating better values for the society. Olympic Heritage belongs to cultural values, especially in countries where the Olympic Games took place. Over three decades ago, Bosnia and Herzegovina (BiH) was a leader in promoting Olympic values during the 1984 Winter Olympic Games. Through questionnaires addressed to the sports federations that are members of the Olympic Committee of Bosnia and Herzegovina (over 30 sports organizations), this paper was used to inspect the value and direction of the cultural dimension related to the Olympic Heritage in Bosnia and Herzegovina. Through the Likert scale consisting of 13 items which were used, important values and the potential development of cultural activities within the Olympic Movement were used and considered in order to provide recommendations for promoting the country’s cultural values in the future. The significance of differences and examinations was determined using the chi-square test (x2). Considering the fact that there is little research on the topic, the authors approach the work by highlighting the elements of culture that are closely connected with the importance of preserving the Olympic Heritage, as well as promotion of culture through sport in Bosnia and Herzegovina. In the future, universities, together with the Olympic Committee and NGOs, could offer new cultural platforms emphasising the Olympic values by spreading awareness and educating the youth through sport and culture. The research results may also be applicable to the Sports Development Strategy of BiH. Keywords: Olympic values, Olympic Heritage, cultural activities, cultural awareness, cultural impact.

The aim of the study was to compare variables of the force-velocity-power (F-v-P) relationship and variables obtained during the Wingate test. Ten elite cyclists participated in the study. Within the same day, all subjects performed squat jumps under four conditions (which were assigned relative to participants’ body mass) and cycle- ergometer testing. Results were compared using a paired-samples t-test and Pearson correlation coefficient (r). We found statistically significant differences between maximum and average power variables (effect size [ω2]: 0.766-0.932) and between the slope of the F-v curve and the power drop during the Wingate test (ω2 = 0.988). Nevertheless, medium-large correlations (r: 0.59-0.85) were found between the results. Anaerobic power and capacity were higher in cyclists who were force-dominant rather than velocity-dominant. Calculating the F-v-P profile in addition to performing the Wingate test provides more accurate information on the anaerobic properties of the leg extensor muscles and allows cyclists to be categorized based on their dominant power production characteristics. In the future, a timeefficient and energy-saving measurement protocol could provide a basis for more accurate definition of training load in resistance training for cyclists, for planning training/competition tactics, and for future studies to optimize the F-v-P profile in cyclists.

The purpose of this study was to research the relation between three different anaerobic performance test outputs. The study was realized on 30 male active athletes who are physically active at volleyball, basketball and wrestling (n=30; 21.8±1.6 years old). Anaerobic performance of athletes was measured using the vertical jump (VJ), 50 yard sprint (AS) and Wingate anaerobic power and capacity test (WAnT). According to the results of Pearson correlation analyzes (r) based on VJ, AS and peak power (PP) out-put of WAnT which were used to evaluate anaerobic performance, it was concluded that although there is a relation between each test method ,these correlations have poor importance (r=0.36 for PP and VJ; r=0.17 for PP and AS, r=0.08 for VJ and AS) since these tests measure different parameters of anaerobic performance.

The Relationship Between Muscle Strength, Anaerobic Performance, Agility, Sprint Ability and Vertical Jump Performance in Professional Basketball Players The purpose of this study was to investigate the relationship between isokinetic knee strength, anaerobic performance, sprinting ability, agility and vertical jump performance in first division basketball players. Twelve male first division basketball players participated in this study. The mean age was 25.1 ± 1.7 yrs; mean body height 194.8 ± 5.7 cm; mean body mass 92.3± 9.8 kg; mean PBF 10.1± 5.1; and mean VO 2max 50.55 ± 6.7 ml/kg/min. Quadriceps and hamstrings were measured at 60° and 180°/s, anaerobic performance was evaluated using the Wingate anaerobic power test, sprint ability was determined by single sprint performance (10-30 m), jump performance was evaluated by countermovement (CMJ) and squat jump (SJ) tests and agility performance was measured using the T drill agility test. Quadriceps strength was significantly correlated with peak power at all contraction velocities. However, for mean power, significant correlation was only found between the 60° left and 180° right knee quadriceps measurements. No measure of strength was significantly related to the measurements from/results of field tests. Moreover, strong relations were found between the performance of athletes in different field tests (p< 0.05). The use of correlation analysis is the limitation of the this study.

The purpose of this study was to investigate the relationship between, isokinetic knee strength, anaerobic performance and sprinting ability in American football players. Twenty-eight male amateur American football players participated in this study voluntarily. Knee extension and flexion strengths were evaluated at 60, 150 and 240/ • s, anaerobic performance was evaluated by Wingate anaerobic power test and sprint ability was determined by single-(20 m) and repeated-sprint (12 × 20 m) tests. Extension strength was significantly correlated with peak and mean power in all contraction velocities; however the only significant correlation between flexion strength and peak power was indicated at 240 • /s. In the case of sprinting ability, there was a significant but weak correlation between 240 • .s −1 knee flexion strength and percentage of performance decrement from 10–20 m (r = 0.381, p < 0.05). No measure of strength was significantly related to single-sprint and other measures of repeated-sprint ability (p > 0.05). Hence, although maximal knee extension strength is a crucial component in anaerobic performance of American football players, lack of its association with single-and repeated-sprint performance indicates that factors other than strength might be involved in single-and repeated-sprint performance in this group of athletes.

Previous test batteries have attempted to accurately measure anaerobic power output in basketball players. At present, there is no standard criterion measure that has demonstrated strong validity or application as a sport specific measure of power. Therefore, the purpose of this study was to determine whether a significant relation exists between the Max Jones Quad test and two established anaerobic power tests in a sample of female Division I basketball players. Subjects (19.7 ± 1.1 years) reported for testing on three separate days. Body composition and the vertical jump test were performed on Day 1. The Max Jones Quadrathalon Test (MJQT), which consists of the following four stations: 1) standing broad jump; 2) three consecutive broad jumps; 3) overhead shot put toss; and 4) 30-meter sprint, was administered on Day 2. Subjects performed a 30-second Wingate cycle ergometer test on Day 3. A significant relation (p<0.05) was found between anaerobic power (Wingate cycle test) and only one of the Max Jones Quad test components (30-meter sprint) (r = -0.57). Additionally, correlations between vertical jump height and Max Jones Quad test components were found to be significant (p<0.05; p<0.01) (broad jump, r = 0.64; 3 broad jump, r = 0.56; 30m sprint, r = 0.69; Total Score, r = 0.70). These results suggest that certain components of the Max Jones Quad test are related to anaerobic power output. Further investigation of the usefulness of the Max Jones Quad test as a sport specific measure of anaerobic power is warranted.

The aim of the present study was to determine the relationship between vertical jump performance and the isokinetic strength of the knee extensors in professional soccer players at the end of the of the competition period, after the detraining period (before the initiation of the preparatory period) and after the completion of the preparatory period. Eighteen professional soccer players participated in the present study. The peak jumping height (of the squat and counter movement jumps on an Ergojump device) was used as indicator of vertical jump performance. The subjects also performed three submaximal and three maximal isokinetic efforts of the knee extensors at angular velocities of 60 and 180°/s. Pearson product moment correlation analyses were conducted to determine the relationship between isokinetic strength and jumping parameters. The significance level was set at p < 0.05. The analysis indicated that jumping height was moderately correlated with the knee torques at the test velocities after the competition and preparatory period.
Conference Paper
The purpose of this study was to investigate the relationship between isokinetic strength of knee, vertical jump and anaerobic peak power. Twenty one healthy young male voluntarily participated in this study. Squat Jump (SJ), Counter Movement Jump (CMJ) and Wingate anaerobic power test were performed. Bilateral concentric isokinetic strength of the knee extensors/flexors was evaluated at 60, 120 and 180 degrees/s. CMJ height had a significant and moderate relationship with the isokinetic knee strength of extension measured at 120 and 180 degrees/s whereas SJ height was not correlated with any of the isokinetic strength parameters. Absolute, and less so normalized, power bore significant relationship to the isokinetic parameters. Hence the relevance of maximal isokinetic knee extension strength may be limited counter movement jumping.
