我国优秀女子铁饼选手旋转阶段肩髋饼速度变化的三维运动学特征

3-D kinematical Analysis on the Velocity of Hip,Shoulder and discus for Chinese Elite Discus Throwers during Rotational Period

用三维运动学分析的方法对我国 4名优秀女子铁饼运动员在旋转进行过程中肩髋部位的技术进行评定 ,研究发现运动员在旋转的准备和开始阶段肩髋速度变化合理 ,在过渡阶段铁饼速度下降较多。在整个旋转节奏上不太合理 ,致使铁饼在整个旋转过程中速度变化不理想。提醒教练员应重视过渡阶段的技术。

The purpose is to find out the weak points and advantages of Home female Discus throwers.By using the method of three-dimenlional kinematical analysis,the author makes an evaluation on the technique of Hip and Shoulder for Chinese elite female discus throwers during rotational period.The Paper discovers That the speeds change of shoulder and hip is reasonable in preparation and beganing rotational period,discus speed descent much in the transition period.It is not reasonable on whole retaional rhythm,so make the discus speed change is not reasonable in whole rotational.The coach should pay more attention to the technique training on the transition period.
