中国优秀女子跳远运动员起跳过程摆动腿技术的运动学研究

运用高速摄影和影片解析法,对我国优秀女子跳远运动员起跳过程摆动腿技术进行研究发现,起跳过程中摆动腿紧密衔接的快速后蹬、加速前摆和制动前摆动作能促使身体重心在不更多损耗水平速度的基础上获得更大的垂直速度,并最终提高腾起瞬间身体重心的垂直位置、初速度和腾起角,对跳远起跳效果和成绩的提高具有显著的促进作用。

Kinematical Study on Free Leg Movement in Take-off Phase of Elite Chinese Women Long Jump

By ways of photo-analysis and statistical induction, the data were surveyed and the following was concluded. The positive action of free leg, quick extending and swing forwards can take good advantages of running velocity and be greatly helpful to the big increase in vertical velocity of the center of gravity. So,it is of major importance for the take-off phase and benefits the result of long jump greatly.
