The aim of present study was to examine the effects of plyometric jump (jump squat) exercises on vertical jump, and to investigate the relation between these exercises and some physical fitness and other defining characteristics in female volleyball players. The sampling of the study consisted of 10 voluntary female players, who were active licensed players at Bursa Nova Sports Club in Turkey Volleyball 2nd League, and who had the following defining characteristics; age: 16±0.8 years; sports age: 9.5±0.1 years; height: 176±6.7 cm; body weight: 65.8±5.7 kg; fat %: 26.9±4.3; fat amount: 17.7±4.2 kg; lean weight 47.6 ± 3.1 kg, total body fluid 34.9±2.3. The participants did not face any disabilities or diseases in the past six months; and participated in the training program regularly. They applied a normal diet during the entire study process. A total of 6 trainings a week, 3 sets in each training, 30 jumps in each set, which means a total of a total of 24 trainings, 72 sets and 2160 plyometric jumps (jump squat) were added to the seasonal training programs of the players for 4 weeks. The Bosco Test was used. On Sunday, one day before the plyometric studies were started, the other 4 Vertical Jump Measurement Tests (T2, T3, T4, T5) -including the determining the vertical jump measurements test (T1) - were carried out on Sundays every weekend. The body composition was determined by the Tanita Body Composition Analyzer TBF-300. The data that were obtained in this way were analyzed with One-Way ANOVA and Pearson Correlations Coefficient tests in the SPSS for Windows 22 Statistical Program. As a result, a statistically significant relation was detected between the vertical jump, which is one of the descriptive characteristics of volleyball players, and the amount of fat % and fat (p˂0.05). The vertical jump arithmetic averages were determined to be T1 33.8±4.8 cm; T2 34.4±4.5 cm; T3 35.2±4.7 cm; T4 36.5±4.9 cm; T5 36.4±4.7 cm (F=34.353; p |
