摘　　要：采用影像分析法、数理统计法等方法,对优秀竞技健美操运动员屈体分腿跳成俯撑动作的运动学规律进行研究探讨,运用T检验方法对受试者的动作进行对比分析,以期把握其动作结构、关节角度及速度的变化特征。研究表明:运动员起跳效果较好,但是在重心上升阶段对小关节的姿态控制欠佳;动作结构呈现重心首先上升至最高点,其次出现最小髋角,继而分腿角最大的特点;另外,上肢与下肢的落地缓冲不同步。The methods of video analysis,documentary analysis and statistics analysis were used in this study.This paper use T-test for subjects＇ movements and analyzed the action law of straddle jump to push up of sports aerobics so that we can find the technology structure and character.The results showed the effect was better of takeoff,but the posture of small joints was not good enough in the air;the structure was that the center of gravity was the highest firstly,secondly,the hip angle was the smallest and then divided legs angle was the biggest;the upper and lower limbs were buffering synchronization.
