大学男子高水平标枪运动员各阶段投掷技术分析

Throwing step of high-level men's javelin athletes in colleges

采用高速摄影对高校高水平男子标枪运动员投掷步和最后用力两阶段进行定点拍摄获得相关运动学参数,同时根据世界优秀标枪运动员有关运动学参数进行对比分析。结果:投掷步获得的动量和扭转力矩缺位,导致"鞭打"、"满弓型"无法完成,投掷步第一、二步躯干角度小,交叉步后倾角度过大。

This article is written on the basis of the kinetic parameter by adopting high-speed photograph and set-photograph on high-level men＇s javelin athletes in colleges.By comparing with the kinetic parameter of top throwing athletes in the world,this article concludes that the absence of momentum and torque made by throwing step causes unfulfillment of whiplash movement,the small trunk angle of the first and second throwing step and the large caster angle of cross-step.
