影响男排运动员单脚起跳效果的主要因素

Main Factors Influencing Effects of Male Volleyball Players' Single-foot Takeoff

采用运动生物力学实验法。结果表明 ,造成男排运动员单脚起跳效果差的主要因素是 ,起跳腿膝关节伸肌离心收缩能力差和摆动腿摆动技术差 ,从而导致缓冲时间长、膝关节缓冲速度慢 ,以及摆动腿摆动速度慢。

The method of sports biomechanical experiment was used in the present study. The results reveal that the poor effect of male volleyball players' single foot takeoff accounts for their weak eccentric contraction capacity of takeoff leg's knee extensor and poor swinging technique of swinging leg, which lead to long buffer time and slow buffer speed of takeoff knee, as well as slow swinging speed of swinging leg.
