掷标枪最后用力速度特征的运动学分析

Kinetic Analysis on Velocity Feature About Final Exertion in Javelin Throw

采用高速摄像法,运动录像解析法以及比较分析法,对李荣祥掷标枪最后用力阶段身体重心和标枪重心水平速度特征,鞭打动作的速度特征以及其它相关指标所体现出的速度特征进行分析,并指出其技术中所存在的不足。

By using the methods of high-speed photography ,photographic analysis and comparison , the author analysed the velocity features about central horizontal speeds of body and javelin ,action of whipping , and correlative indexes of the final exertion and pointed some problems needed to be improved .
