对我国男子标枪运动员“交叉步”和最后用力技术的某些运动学特征的初探

A Prelininary Study on Some Kinematic Characteristics of Cross-Stride and Final Exertion Skills in Chinese Male Javelin Throwers

本文运用影片分析的方法,通过对中外男子优秀标枪运动员掷标枪技术的分析,发现我国运动员“交叉步”腾空过高、过大现象与运动中左肩、左臂上翘有着密切关系,同时发现我国运动员最后用力顺序和最后用力程度存在明显不足。

In this paper, skills of elite male javelin throwers at home and abroad were studied and compared by means of film analysis. Results show that the excessively higher and bigger lift of cross-stride in Chinese javelin throwers has close relationship with the upward position of their left shoulder and arm. It is also discovered that there exist insufficience and improper sequence in Chinese throwers final exertion.
