文章以2020东京奥运会女子标枪前八名运动员最后用力阶段身体技术表现为研究对象,对2020东京奥运会女子标枪最后用力阶段的身体技术中的左右侧进行研究。方法:主要采用专家访谈法、视频分析法和及数理统计法。结果:最后用力阶段右侧身体技术中存在未完成“满弓”技术动作的行程;第四名至第八名运动员控制肘关节失利导致肘关节转动过早;第四名至第八名运动员转肘翻肩动作完成得过早;第二名至第八名运动员左腿能够承受负荷较大冲击力的水平比较差能量损失比较大;三至八名运动员的左腿蹬伸能力比较差。

OBJECTIVE:This article takes the final body technique before releasing the javelin by the top eight women javelin throwers at 2020 Tokyo Olympic Games as the research object,and studies their body left and right sides techniques for the throw.METHOD:It mainly adopts expert interview,video analysis and mathematical statistics.RESULTS:(1)In the right body side technique,the throwing arm was not fully extended behind before releasing the javelin;(2)The athletes at ranks4 to 8 failed to control their elbow joint,resulting in early rotation of the elbow joint;(3)The athletes at ranks 4 to 8 completed the elbow rotation and shoulder rotation too early;(4)The athletes at ranks2 to 8 withstand a low level of impact load on left legs,and the energy loss is relatively large;and(5)The athletes at ranks3 to8 are relatively weak at the left legs'push and extension abilites.
