国内外优秀男子标枪运动员最后用力技术运动学特征的对比分析

Comparative Analysis on Final Push Technology Kinematic Characteristicsof Elite Javelin Male Players at Home and Abroad

通过运用三维运动学分析的方法,对现阶段我国15名运动员32次的试掷进行研究发现,我国选手在最后用力中存在右脚着地瞬间躯干倾角偏大,身体对器械的超越不够,"满弓"形成瞬间上体抬起过大,上肢移过支撑点过早,右肘弯屈过大和提前用力等问题,缩短了最后用力的距离和幅度,造成"满弓"动作和用力效果不好等现象。

By using three - dimensional kinematic analysis on the present throwing 32 trial of China＇s 15 athletes, the author found China＇s players＇ s right angle to the tnmk moment getting beyond the body of the instrument enough in the final force, ＂full bow＂ to form an instant lift the upper body, the upper support from premature shift, bended right elbow too much, ahead of force, caused bad effects of ＂full bow＂ motions and forced effect.
