This study aims to analyze the relationship between anaerobic performance and leg and foot volume and mass in female athletes in individual sports and team sports. 90 female athletes who have been active in sports for at least three years voluntarily participated in the study. The average age of participants is 21. Frustum and Hanavan methods were used to calculate leg volume and mass, respectively. 20-meter sprint test and vertical jump test were carried out in order to determine anaerobic performance. SPSS 22.0 package program for Windows was used for descriptive statistics and correlation analysis of the obtained data. In this study it was demonstrated that leg volume and mass of female athletes varied in each sport and that right and left leg volume and mass of these athletes were fairly close.  Leg volume and mass were higher in team sports athletes than individual sports athletes. In addition, vertical jump performance was better in individual sports athletes. Therewithal it was found very highly negative significant correlation between vertical jump and 20-meter speed values in individual and team sports. As a result it was found that leg volume and mass were higher in team sports athletes than individual sports athletes. Besides when the relationship between leg volume and mass and anaerobic performance is analyzed, a very high positive significance was found between 20 meter speed and right leg mass in boxers. In this way the development of both leg volumes and mass is therefore important for a better anaerobic performance for athletes.

The Relationship

This study aims to analyze the relationship among somatotype structures, leg volume, leg mass, anaerobic strength and flexibility of elite male athletes in different branches. 90 male athletes who study at School of Physical Education and Sport at University of Kırşehir Ahi Evran and are active in wrestling (n=15), gymnastics (15), football (15), handball (15), volleyball (15) and basketball (n=15) voluntarily participated in this study. Somatotype structures, leg volumes and leg masses of the participants were determined using Heath-Carter, Frustum and Hanavan methods, respectively. Vertical jump test was used to measure anaerobic performance, while sit-and-reach test was used for flexibility performance. Spearman correlation analysis was performed using SPSS 22.0 package program for Windows, and the level of significance was taken as 0.05. As a result, a significant correlation was found between leg volume and mass and anaerobic performance values in football, volleyball, basketball, handball, wrestling and gymnastics, which indicates a decisive role in anaerobic performance. It was observed that athletes with a higher amount of leg volume and mass display a better anaerobic performance. The width of femur circumference and a high amount of muscle mass and fiber in the femur lead to a higher strength in muscles and maximizes the strength.

Objective: The purpose of this study was to identify relationships between endurance of periscapular muscle, anaerobic performance and agility in professional athletes. Methods: 70 professional basketball, volleyball, and handball players (male: 25 female: 45 age 20.41±5.72, BMI: 21.70±2.51) were included to this study. Anaerobic performance was assessed with vertical jump test. Periscapular muscles endurance was evaluated using scapular muscle endurance test and agility was measured hexagonal obstacle test. Statistical analysis was performed using the statistical software SPSS 22. Results: Spearman correlation analysis results showed that there was positive significant correlation between anaerobic performance and endurance of periscapular muscles (p<0.05 r=0.341). A negative significant relationship was demonstrated between anaerobic performance and agility (p<0.05 r=-0.332), and between agility and endurance of periscapular muscles (p<0.05 r=-0.334). Discussion: The scapula acts as an axis, transmitting the power and high energy of the lower extremities and trunk to the upper extremities. The muscles surrounding the scapula provide proximal stability for the upper extremity and act as a fix while the distal part is moving. When weakness of scapular musculature has occurred, normal scapular positioning and mechanics may be altered. Therefore, scapular stabilization failure may lead to poor anaerobic performance. These results indicate that periscapular muscle endurance affects anaerobic and agility performance in sports.

The Relationship Between Muscle Strength, Anaerobic Performance, Agility, Sprint Ability and Vertical Jump Performance in Professional Basketball PlayersThe 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 VO2max50.55 ± 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.

Background: The aims of this study were to analyze the effects of the COVID-19 pandemic and its subsequent confinement on behaviors, perception of threat, stress, state of mind and training patterns among Olympic and Paralympic level athletes. Methods: Data gathering was performed utilizing an online questionnaire during imposed confinement. A correlational design with incidental sampling for convenience was used. All the variables were analyzed by age, gender, academic training, type of participation and sport specialty on a population composed of 447 Olympic (age: 26.0 ± 7.5 years) and 64 Paralympic (age: 28.4 ± 10.5 years) athletes. Results: The athletes trained more than twice as many hours before than during confinement. Most of the athletes recognized that their best athletic performance diminished due to the COVID-19 confinement but that will recover after the pandemic and its confinements. Almost half of the athletes declared they were more tired than normal and had difficulty sleeping, while more than half ate more or less as usual. Paralympic athletes reported they felt more capable to cope with personal problems and life events and felt less lonely during the confinement than the Olympians. The athletes from team sports reported to be more affected in their training routine than athletes of individual sports, seeing their athletic performance more affected. Athletes in individual sports felt more able to cope with personal problems than athletes in team sports. Female athletes were significantly more tired and reported more difficulty sleeping than male athletes. Conclusion: The situation caused by COVID-19 has had significant effects on the behavior, perception of threat, stress and training patterns of Olympic and Paralympic athletes preparing for the 2020 Tokyo Olympics. It is necessary that sports institutions reinforce mechanisms of help for athletes during future situations of confinement.

Introduction: The aim of the present study was to investigate the effects of postactivation potentiation (PAP) in vertical and horizontal jump performance in pre-pubertal children. Material and method: One hundred and nineteen children (65 girls and 54 boys; 6.8 ± 0.7 years old; 124.5 ± 6.4 cm; 25.2 ± 5.1 kg) participated in this study. This was a transversal cross-sectional study which incorporated a within-subjects repeatedmeasures design, where participants completed all protocols. The experimental procedure required four total testing, separated by one week, using a counterbalanced. This study investigated jumping performance associated with weighted jumps, lowload vertical jumps, and horizontal jumps. During two sessions the participants performed vertical jumps with and without PAP, the other two sessions the same procedures were performed for horizontal jumps. The PAP protocol consisted of one set of five weighted countermovement jumps with low-load (10% of body mass) and a rest interval of four minutes prior to the jump tests. Paired t-tests were used between conditions (PAP and control) in the vertical jump and horizontal jump test. In addition, Cohen’s d effect size and 95% confidence interval was used. Results: Significant jump height was observed in the vertical jump in the PAP condition compared to the control condition (p = 0.007). Similar results were observed for the horizontal jump tests, with significant longer distance observed in the PAP condition (p = 0.036). Conclusions: Pre-pubertal children can benefit from the effects of PAP in vertical and horizontal jumping performance when preceded by low-load ballistic movements. A protocol implementing low-loads, determined by a relative percentage of body mass is effective to promote PAP for young children.

The purpose of this study was to compare the level of cognitive flexibility of individual and team athletes who are students. The study included a total of 237 volunteer athletes, comprising 140 males (59.1%) and 97 females (40.9%) with a mean age of 18.98 ± 2.18 years (range, 16-26 years) who were licensed to participate in individual and team sports. Study data were collected using the Cognitive Flexibility Scale developed by Martin and Rubin (1995), which consists of 12 items in total. International validity and reliability studies were conducted by Martin and Rubin, and Turkish validity and reliability studies were conducted by Çelikkaleli on high school students (Çelikkaleli, 2014). The scores of the Cognitive Flexibility Scale were found to be higher in the team sports athletes compared with the individual sports athletes (p<0.05). No difference was determined between the levels of cognitive flexibility in male and female athletes. The results indicated that the cognitive flexibility levels of team athletes are higher than those of individual athletes.

Purpose: To describe and identify individual trends and changes in training load, neuromuscular readiness, and perceptual fatigue measures in 2 youth elite long jumpers, finalists at the European Athletics U18 (Under 18) Championships (athlete A, female, age 16.5 y, long-jump record 6.25 m; athlete B, male, age 16.0 y, long-jump record 7.28 m). Methods: Data were collected from both training sessions and athletics competitions during a 16-week period, divided into a preparation (weeks 1–8) and a competitive phase (weeks 9–16). Training load was computed through training diaries (training time, sprint, jumping, and weights volume). The countermovement jump and the 10-to-5 repeated-jump test were executed on a weekly basis to assess neuromuscular readiness, and perceptual fatigue measures were collected through a wellness questionnaire. Statistical analysis was conducted using a magnitude-based decisions approach. Results: The results highlighted a decrease in training load during the competitive period with moderate to large differences for training time, sprint, and jump volume. Moreover, data showed an upward trend and very likely higher scores in vertical-jump performance across the competitive phase together with a very likely lower perceptual fatigue. Conclusions: This scenario seemed to be favorable to achieve competition performance very close to the personal record during the competitive season. This study provided an example of application of a comprehensive monitoring system with young athletes involved in track-and-field jumping events.

Abstract The evaluation of match officials’ neuromuscular performance is now an important consideration and the vertical jump test is considered suitable for assessing lower limb power, partly because it is directly related to refereeing. The aim of this study, therefore, was to determine the effect of soccer matches on match officials’ vertical jump performance by assessing various biomechanical variables. Eighteen field referees (FRs) and 36 assistant referees (ARs) who officiated in 18 official matches participated in this study. Before the match, at half time and immediately after the match, officials performed two countermovement jumps. Flight phase time (FT), maximum force production (MFpropulsion), time to production of maximum force (TMFpropulsion), production of maximum power (MP), maximum landing force (MFlanding) and time to stabilization (TTS) were calculated for all jumps. There was a tendency for match officials’ jumping performance to improve after matches than beforehand (FR: effect size (ES) = 0.19 ± 0.36, possibly trivial; AR: ES = 0.07 ± 0.17, likely trivial). There were also likely small and very likely moderate differences between FRs’ MP in pre-match and half-time jumps (ES = 0.46 ± 0.47) and in their pre- and post-match jumps (ES = 0.71 ± 0.48). These results indicate that refereeing soccer matches does not reduce vertical jump performance; the subsequent neuromuscular fatigue is not sufficient to affect landing technique.
