The Effect of Flexibility and Body Fat Percentage on Vertical Jump Performance with Volleyball Players

The purpose of the current study is to investigate the effect of flexibility and body fat percentage on vertical jump performance with 20 female and 20 male volleyball players from Ondokuz Mayis University Yaşar Doğu Physical Education and Sport High School. All participants age, height, weight, flexibility (sit and reach), body fat percentage and static, counter and drop jump heights were measured. Female and male volleyball player’s mean age 21.08±1.5 year, body mass index 22.9±2.3 kg/cm², flexibility 17.3±5.8 cm, percent body fat 12.1±1.4, average height of static jump (SJ) 33.6±10.1 cm, counter movement jump (CMJ) 36.1±12.3 cm and drop jump (DJ) 33.6±10.6 cm. volleyball players of different jump performance of the highest average in both men (45,3±8,06) and women (26.9±8.5) have achieved with CMJ height. Male athletes with the SJ height values of flexibility, CMJ heights and DJ heights were statistically significant correlation (r=.508, r=.551, r=.450, p 0.05). The correlations of men’s body fat percent age and SJ height were statistically significant (r=.479, p 0.05) and this finding was similar in comparison to others in literature. Both men(r =-.430, p 0.05) and women (r =- .349, p 0.05) negative relationship between flexibility values and percentage of body fat. In our study female volleyball players vertical jumping performance relation with body fat percentage was not significant (p 0.05). As a result, the flexibility provided by a positive contribution to the performance of the vertical jump, where as the increase in body fat percentage was adversely affected the flexibility.
