我国三名优秀女子铅球运动员过渡阶段技术特征的研究

A Study on the Technical Characteristics of the Top Three Chinese Woman Shot-put Athletes in the Transitional Phase

采用一台日本产的JVC 9800小型数码摄像机对我国三名优秀女子铅球运动员李梅菊、程晓燕、张小雨在2004年度内二次比赛和一次训练的专项技术动作进行定点、定焦距、高速拍摄,采用录像数字化数据平滑处理和运动生物力学计算机辅助解析和辅助教学系统——Sbcas2软件解析以及体育统计等方法得到每名运动员过渡阶段运动学参数,通过对这些数据的比较和分析,发现不同运动员过渡阶段技术的特征,为教练员和体育工作者提供参考。

In this research ,the technical motions of three Chinese elite woman shot-put athletes Li Mei-ju, Cheng Xiao-yan and Zhang Xiao-yu were taken during two competitions and one training course in 2004 at fixed points and focus and with high speed by a small-scaled Japanese digital camera JVC9800. By means of sports Biomechanical CAA and CAI System Sbcas2 software to digitalize the disposed images ,the kinetic parameters of each athlete in their transitional phases are obtained. Through analyzing and comparing the data, the technical characteristics of different athletes in the transitional stage are discovered so as to provide references for the coaches and sports workers.
