男子背越式跳高运动员助跑最后一步摆动腿支撑技术的运动学分析

Kinematic analysis of the swinging leg and support technique on the course of the last approaching

运用影片拍摄及解析的方法对我国优秀男子背越式跳高运动员摆动腿在助跑最后一步支撑过程的运动学特征进行了分析 ,得出我国优秀男子背越式跳高运动员在助跑最后一步支撑过程中身体重心的运动轨迹、重心速度、位移等运动变化情况。同时证明 ,在助跑最后一步摆动腿的支撑技术对身体重心的运动状况具有重要的影响。

The kinematic analysis of the swinging leg and support technique in the course of the last approaching stride of Chinese elite male fosbury flop was made with film shooting and analyzing.Kinematic charges such as the moving track,speed,displacement of body's center of gravity were found in the swinging leg's support in the course of the last approaching stride of Chinese elite male fosbury flop.It was proved that the supporting techniques of the swinging leg in the last approaching stride had great influence on the motion of the body's center of gravity.
