中外优秀男子链球运动员投掷技术的运动学分析

Outstanding Hammer Sportsman Man of China and Foreign Countrise Throw the Kinematics Comparatire Anatysis of Technyue

采用高速摄影解析方法和文献资料法 ,对中外优秀男子链球运动员的投掷技术进行生物力学比较分析。结果表明 ,我国运动员球速增量差距较大的是在旋转的第二圈和第四圈 ,其原因在于旋转时间长 ,单、双支撑时间不合理和d/s比率低。旨为提高我国男子链球运动员投掷技术提供理论依据。

By using film analysis and documentation methods,the author made a comparative study on both home and abroad elite hammer throwers The study reveal that the main linear velocity increasment lags behind comparing with those abroad in second and fourth turn,which result from the slow turn and the irrational time duration in single and double support (low d/s ratio)
