(r = 0.755, p < 0.01; r = 0.664, p < 0.05; r = 0.713, p< 0.01, respectively). Standing broad jump performance correlated with foam surface, tandem leg and total BESS score (r = 0.737, p < 0.01; r = 0.692, p < 0.05; r = 0.617, p< 0.05, respectively). There was a statistically significant relationship among the single leg BESS score and vertical jumping performance (r = -0.596, p<0.05). In conclusion, the activities requiring explosive power may reflect the ability of managing a balanced posture but the activities in which time period is longer may not.

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.

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.

Aim of this study is to analyze the effect of a 8 week-explosive power training on some performance parameters of students who studying in sports high school. A total of 101 healthy male canoist students who studying in sports high school volunteered to participate in this study. students were randomly divided into two groups and test (N = 51) and control (N = 50) groups were formed. Explosive power trainings were applied to test group during 8 weeks as 30-minute trainings for 3 days a week in addition to canoe training and control group continued only canoe training. All data were obtained twice as pre-test and post-test before and after training. Four line sprint test, standing long jump test and 20m sprint test were used to determine performances of the subjects When results of the study are examined, it is seen that explosive power trainings applied during 8 weeks had statistically significant effects in favor of the post-tests for 20m sprint, sprint-agility and standing long jump performances pre-test and post-test results (P<0.05). In addition, when post-test results of test and control group were compared, it was found that test group's 20m sprint, sprint-agility and standing long jump performances post-test results showed statistically more significant improvement than control group's post-test results (P<0.05). These results confirm our expectations before the research. Consequently, it can be thought that explosive power trainings applied have positive effects on 20m sprint, sprint-agility and standing long jump performances.
