采用文献资料、三维定点摄像法、影像解析法等研究方法对参加2009年国际田联竞走挑战赛的优秀20 km竞走运动员的髋关节技术进行系统分析,研究发现：髋关节的运动特征是支撑腿髋关节向外前移,另一侧髋关节由上向下的前旋运动,然后两髋交换运动形式的周期性空间运动;髋关节在各方向的速度特征可以在一定程度上说明两髋的协调性,中国运动员需要增大额状面内的摆动幅度,提高支撑腿髋关节的水平速度;髋关节在支撑阶段和摆动阶段的位移距离存在一个最佳比例,部分中国运动员的比例存在问题。

This article adopted the methods of literature,fixed photography of three dimensional,and video analyzing to conduct a systematic analysis on the hip joint techniques of the elite athletes of 20 km walking race in 2009 IAAF walking race.Research findings： Hip joint motion characteristics are the periodic space movement which the supporting hip moves to front outward and another hip swings to front rotary,then two hips change the movement;The velocity characteristic of the hip at each direction can explain the compatibility to a certain degree,and the Chinese athletes need to increase the swing extension,and improve the horizontal velocity of the hip joint of supporting leg;The displacement-distance of the hip joint in supporting and swing phases has a optimal proportion,but part of Chinese athletes has problem in the proportion.
