采用文献资料法、三维录像解析法以及数理统计法等研究方法,以孙太凤在2007年全国田径锦标赛中的5次有效投掷研究对象,对孙太凤在掷铁饼旋转技术的时间、空间以及速度节奏进行了定量分析。同时采用Person相关分析对影响孙太凤投掷成绩的时间、空间以及速度的变化进行了检验,提出了孙太凤掷铁饼旋转节奏的量化指标。

By means of literature research, three-dimensional video analytic method and mathematical statistics method, five targets of Sun Tai-feng’s throwing in the National Track and Field Championships in 2007 were studied effectively. The time, space and speed rhythm of the discus discus rotation were carried out Quantitative analysis. At the same time, Person’s correlation analysis was used to test the changes of the time, space and speed that affect the throwing performance of Sun Taifeng, and the quantification index of the throwing tempo of Sun Taifeng’s throwing discus was put forward.
