钟宇萍直体后空翻两周转体720°旋翻动作的三维运动分析

Three-Dimension Kinernatical Analysic of Zhong Yuping's Straight-Body Backward 2 Somsault with 720° Twisit

使用三维高速同步摄影系统对目前技巧女子单人项目最高难度的旋翻动作进行了研究和分析,指出了钟宇萍直720°旋的空间变化特点,寻找出了其存在的主要技术问题,并以此填补和丰富了旋翻类动作的技术理论。对该动作从三维角度做出定量性研究的文章目前尚未见到。

This paper,by using three-dimension high speed photograph, the straight-body backward 2 somesault with 720° twists which is one of the mosr difficult movements of women' single events in the tumling are studied and analysed the 3-d Varied characters of body during airflight are found. The technical problems of the part are pointed out. These conclusions are important to develop technical theory of somsault and twist.
