摘要:
采用文献资料法、专家访谈法、三维高速影像解析法和数理统计法,对现阶段我国优秀女子铁饼运动员旋转技术的时空特征进行分析,得出以下结论:重心和铁饼的分速度大小及比例对运动员技术风格的形成有重要影响;在旋转技术完成瞬间,李艳凤和宋爱民的铁饼合速度分别是最大和最小的,不同的是李艳凤水平分速度占的比例大,宋爱民垂直分速度占的比例大,孙太凤在左脚单支撑阶段铁饼速度较快,导致腾空和过渡阶段铁饼速度下降;在左脚单支撑阶段,宋爱民右髋的速度最大导致她重心轨迹偏向左,孙太凤最慢的右髋速度和最快的右肩速度使她的重心轨迹偏右;李艳凤在过渡阶段过快的肩关节速度是她获得较快饼速的主要原因之一。在形成最后用力双支撑瞬间,我国运动员的肩轴角速度要大于髋轴,说明我国运动员已经开始最后用力
Abstract:
This article adopted the methods of literature, expert interview, photography of three dimensional in high speed, and mathematic statistics to analyze the rotation technique of Chinese elite women's discus throwers.It has been shown that size and proportion of component velocity of CG and discus have very important influence to form athlete’s technique style; Body-discus system at flight and transition stage is very complex and the most difficulty controllable. System changes in the two stages have the decisive effect to form personal optimum technique; the second and third rotation axis of Chinese athletes have steady velocity transfer. Hip and knees velocity of the second axis decide the style of displacement. The shoulder velocity of third has a close relation to the space-time characteristics of discus.
