摘　　要：运用高速摄影与解析的方法,对我国优秀男子跳高运动员比赛中不同高度跳次间,摆动腿在助跑最后一步支撑过程的技术特征进行对比分析。结果表明:摆动腿支撑过程质心水平速度、质心高度、蹬伸阶段质心前移水平距离、膝关节角度等方面均存在一定差异,认为:质心水平速度的降低,是运动员试跳失败的制约因素之一。The method of high-speed photograph and analysis of it was applied to making a comparative analysis of the technical characteristics of good high jumpers' swinging-leg supporting in the last-step approach of different height trials in competitions. The result indicates that there exist a certain differences not only in the horizontal velocity of center of gravity (CG) and the height of CG when swinging-leg supporting, but also in the horizontal distance of CG moving forward during swinging-leg driving off and in the angle of knee. It holds that the decrease in the horizontal velocity of CG is one of the reasons for failure in high jumpers' trials.
