对我国部分优秀女子背越式跳高运动员起跳技术的运动学分析

通过高速摄影对全国大奖赛女子跳高比赛前4名运动员的最后4步助跑技术进行3维运动学分析,得出中国运动员起跳时支撑腿蹬伸不充分,起跳脚着地至离地瞬间身体重心水平速度的转化率优于世界优秀运动员,起跳腿蹬伸离地瞬间髋、膝、踝3关节都没有充分伸展等研究结果。

The Kinematics Analysis Of Take-Off Technology For Some Chinese Outstanding Female Back-Style High Jump Athletes

Through the highspeed photography to the national grand prix women＇s high jump athletes before the game 4 of the last four step approach on the 3 d technology kinematics analysis, the re.search results show that Chinese athletes takeoff support legs when push to stretch not fully, up from the ground TiaoJiao touchdown to body weight level of the moment speed conversion is better than the world excellent athletes, takeoff leg out to push from the moment hip, knee, ankle joints are not fully extended.
