| Summary: | 碩士 === 國立臺灣體育運動大學 === 競技運動學系碩士班 === 100 === The study is to compare the performance and physical quality of different jumping style, and to discuss the height of jumping, reaction time, and kinetics parameter, and also the physical quality differences between different jumping style of volleyball players, one-foot jump and two-foot jump. The experiment takes sixteen UVL Open group first level male volleyball players as participants. The kinetics parameter was experimented with Kistler’s force plate to capture one-foot and two-foot group participants’ reaction time and ground counterforce value, and used formula to calculate their height of jumping. Specialized physical fitness experiments all participants with six specialized volleyball physical fitness, and take the collected data as basis of physical quality, and was analyzed with SPSS for windows 17.0. The data of performance and physical quality of different jumping styles were tested with Independent- sample T test, and the statistical standard is p<0.05. The results are as follow:
The take off time of one-foot jump (0.33 sec)is faster than two-foot jump(0.42 sec), but its ground counterforce is smaller than two-foot jump(one-foot: 2.89 times of weight; two-foot: 3.29 times of weight), so as the impulse, and the height of two-foot jump(one-foot: 0.33m; two-foot: 0.43m). The Maximum ground counterforce also performs earlier(one-foot: 0.19sec; two-foot: 0.29sec).
The one-foot jump group (6.43sec)is only significantly faster than two-foot jump group (7.10sec, t=2.942, p <.05)in 9 meters shuttle run, and the rest tests are not significant between two groups. Result shows that one-foot jump techniques may more ability in speed, agility and coordination capacity then two-foot jump techniques.
