BAYAN VOLEYBOLCULARDA ESNEKLİK EGZERSİZLERİNİN DİKEY SIÇRAMA PERFORMANSI ÜZERİNE ETKİLERİ

11 females athletes, who play volleyball in 3rd league, whose average ages are (18.36  0.67) years, average heights are (171.45  7,76) cm, and body masses are (58,18 4,58) were provided to voluntarily participate in the study. After determining body compositions of volunteers, [in the context of ] 5 types of dynamic exercise movement specific to volleyball branch, static stretching exercise of 8 x 2 s were applied to 4 different groups of muscle. After this application, participants performed the dynamic and static exercises in the separate days and full squat, half squat, and counter movement jump tests were applied. Dynamic half squat jump, dynamic full squat jump, dynamic counter movement jump, static half squat jump, static full squat jump, and static counter movement jump were measured as (31.86 ± 2.05) cm, (31.71±1.30) cm, (37.20±1.49) cm, (32.86 ± 1.86) cm; (34.25±1,67) cm; and (37.91±1.50) cm, respectively. When the mean measures of dynamic (30.46 ± 1.27) and static (32.94±1.63) full squat jumps are assessed, it was identified that there was a significant difference between the mean values of dynamic and static full squat jump measurements (p=0.002<0.05 ). It was identified that there was a statically significant difference between the mean values of dynamic and static full squat 1st jump measurements (p=0.015<0.05) Again, it was found that there was a statistically significant difference between the mean values of dynamic and static full squat 3rd jump measurements in the quality supporting mean values of our measurements (p=0.007<0.05). It was identified that there was no significant difference between the values of dynamic and static half squat jump It was also identified that there was no significant difference between the values of dynamic and static counter movement jump. The values of counter movement jump showed statistically significant difference compared to the other jump values. The findings of the study show that in volleyball players, static stretching increased performance and that high jumping data were reached, when compared to dynamic stretching exercise. In the branches like volleyball, where jumping is important, when short tine static stretching exercise was added to pre-performance exercises, it can be said that positive results may be obtained.
