我国优秀女子铁饼运动员最后用力阶段身体重心运动节奏特征分析

Analysis on the Rhythm of Center of Gravity in Release Stage by Our Civil Female Elite Discus Thrower

采用文献资料法、三维录像解析法以及数理统计等研究方法,以2007年全国田径锦标赛女子铁饼前8名的投掷技术为研究对象,对我国优秀女子铁饼运动员在掷铁饼最后用力阶段身体重心的时间、空间以及速度节奏进行了定量分析。同时采用Person相关分析对我国优秀女子铁饼运动员最后用力阶段身体重心的时间、空间以及速度的变化与投掷成绩进行了检验,提出了我国优秀女子铁饼运动员最后用力阶段身体重心节奏变化的量化指标。

By using the methods of documentation, 3D video analysis and mathematical statistics, this paper studied the technique of first 8 discus throwers in National Track and Field Championships in 2007. The rhythm of center of gravity about time, space and speed in release stage was quantitative studied. By means of Person correlation analysis, the throwing achievements of time, space and the speed of change in center of gravity were tested. Quantitative indicators on the rhythm of center of gravity by our civil outstanding female discus thrower were proposed.
