This study aims to analyze the relationship among somatotype structures, body compositions and estimated oxygen capacities of elite male handball players in Ahi Evran University Handball Team in 2017-2018 Turkish Men's Handball First Division. It was conducted on elite male handball players (n=15) aged between 18 and 30 who voluntarily participated in the study. Their arithmetic means and standard deviations are 22.06±3.80 years of age, 186.00±7.62 cm height, 88.66±10.69 kg weight, and BMI 25.65±3.08 kg/m2, aerobic power (VO2 max.) 41.39±3.86 (ml/kg/min), and 13.10%±1.70% body fat. They had endomorph and mesomorph (4.43-3.96-2.14) in terms of somatotype properties. A highly negative significant correlation was found between VO2 max and body fat % (r=-.702, p<0.01), between VO2 max and endomorph value (r=-.702, p<0.01), and between VO2 max and mesomorph value (r=-.703, p<0.01), while a highly positive significant correlation was found between VO2 max and ectomorph value (r= .609, p<0.05). In conclusion, it can be stated that differences in body fat data may result from players' somatotypes categories, intensity of training, duration of training, measurements by different researchers, measurements in different periods of the season, and use of different formulas in the calculation of measurement values.

This study aims to analyze the relationship between somatotypes and speed of 180 male sub-elite athletes aged between 18 and 25. Athletes were divided into two categories as balanced group (balanced somatotype groups) and randomly selected groups (groups outside balanced somatotypes groups) based on their somatotype structures. The arithmetic means and standard deviations of groups are (n=30) 21.95±2.80 years of age, height 168.40±2.62 cm, weight 69.20±5.26 kg in balanced endomorph group, (n=30) 21.60±3.15 years of age, height 170.25±6.39 cm, weight 67.25±6.09 kg in balanced mesomorph group, and (n=30) 20.40±1.46 years of age, height 175.10±5.02 cm, and weight 60.05±5.09 kg in balanced ectomorph group. On the other hand, the same values are (n=30) 21.35±2.30 years of age, height 160.10±2.20 cm, and weight 69.30±5.70 kg in random endomorph group, (n=30) 21.36±2.40 years of age, height 169.24±2.21 cm and weight 65.40±3.25 kg in random mesomorph groups, and (n=30) 20.50±1.85 years of age, height 176.15±3.30 cm and weight 70.10±4.45 kg in random ectomorph group. The measurement data were analyzed using SPSS 2.0 package program for Windows. Somatotype calculations were done in SOMATOTURK Calculation Program. The statistical analysis demonstrated that a highly positive significant correlation (p˂0.001) was found between balanced somatotype groups (balanced endomorph, mesomorph and ectomorph) and randomly selected somatotype groups (random endomorph, mesomorph and ectomorph).

This study aims to analyze the somatotype structures in students studying at different departments of physical education. A total of 300 male students (elite-sub-elite athletes) who study physical education and sports (n=100), coaching education (n=100) and sports management (n=100) at School of Physical Education and Sports at University of Kirsehir Ahi Evran voluntarily participated in this study. Somatotype structures were determined using Heath-Carter method and SOMATOTURK calculation program. SPSS 22.0 package program for Windows was used for correlation analysis, and the level of significance was taken as 0.05. The results indicate that while students (elite-sub-elite athletes) participating in the study had a mesomorph structure, which is one of the most important body structure parameters for performance and characterized by a muscularity component, during early periods of their education (freshman and sophomore years), their bodies transformed into an endomorph structure, which is characterized by fat components, during later periods of their education (junior and senior years).

This study aims to analyze the effect of the relationship among leg volume, leg mass and flexibility on success in university student elite gymnasts. It was conducted on Haliç University, Marmara University, Çukurova University and University of Kırşehir Ahi Evran gymnastics teams (male and female) which took part in Turkish Intercollegiate Gymnastics Championship and, later, voluntarily participated in this study. While years of age, height and weight of male gymnasts participating in the study were 21.20±1.57, 174.00±4.57 and 67.60±6.46 kg, respectively, the same values were 21.00±2.65 years of age, 165.31±4.60 cm and 54.62±4.63 kg for female gymnasts, respectively. Spearman correlation analysis was performed using SPSS 22.0 package program for Windows, the level of significance was taken as 0.05. The analysis results indicate a highly positive significant correlation (r=.761, p<0.001) between leg volume and leg mass in male gymnasts, a highly positive significant correlation (r=.674, p<0.01) between leg volume and leg mass in female gymnasts, a highly positive significant correlation (r=.795, p<0.001) between leg volume and leg mass in male and female gymnasts, a low positive significant correlation (r=.361, p<0.05) between leg volume and success in male and female gymnasts, and a moderate positive significant correlation (r=.463, p<0.05) between leg mass and success in male and female gymnasts. As a result, gymnastics as a sport requires a combination of speed, strength, endurance, agility, and flexibility. Speed, strength, agility and flexibility are important parameters for training and performance. In addition, an optimal amount of leg volume (13000 ml, 14000 ml) and leg mass (13-14 kg) contribute to success in elite gymnasts.
