摘　　要：本文采用三维录像解析法、Person相关分析等方法,以2007年全国田径锦标赛中孙太凤的5次有效投掷技术为研究对象,对孙太凤掷铁饼最后用力技术阶段的运动学参数与投掷成绩进行相关分析,结果显示:在左脚着地瞬间以及铁饼出手瞬间存在着与投掷成绩密切相关的运动学参数,同时,在最后用力的初始加速阶段、最后用力的最后加速阶段以及整个最后用力阶段也存在着与投掷成绩密切相关的运动学参数。By using the methods of 3D video analysis and person-related analysis, this paper makes research on SUN Tai-feng 5 discus thrower’s technique in National Track and Field Championships in 2007. The correlation analysis about kinematic parameters at the delivery stage and performance was made. The result shows that in the moment of left leg lands and delivery, this has closely related indexes of kinematic parameters to performance. In addition, at the different stages, this has significant correlation between kinematic parameters and the perfor-mance.
