优秀女子铅球运动员周淑琴掷球技术的运动学分析

Kinetic Analysis on Throwing Technique of Elite Woman Shot Putter Zhou Shu-qin

运用CYBEXⅡ^+等速测力系统,对我国优秀女子铅球运动员周淑琴的膝、肘、踝关节的层伸肌进行测试和评定;并运用高速摄影——影片解析系统,对其掷球技术进行运动学分析。结果显示,周淑琴的膝、肘关节肌力和层伸肌力处于较高水平,已形成适合自己身材特点的平快掷球技术;但踝关节伸肌力较弱,层伸肌力比不平衡。

By using CYBEXII high-speed force test system, the flexors of Zhou Shu-qin's knees, elbows and ankles are measured and evaluated. The kinetic analysis on her throwing techniques is conducted by high speed photograph-film analysis system. The results show that the muscle force of Zhou's knees and elbows and kipping muscle force have reached higher level, and Zhou Shu-qin has formed the unique throwing techniques which suit her body features.
