【摘要】 使用高速摄像对两名不同水平男子背向滑步推铅球选手投掷时身体环节的速度变化进行生物力学分析。结果表明,两名运动员最后用力时身体重心和胸部的速度变化存在明显区别,身体投掷一侧各环节的速度变化也有所不同。制定了推铅球最后用力身体环节速度递增系数。更多还原

【Abstract】 We make the biomechanical analysis of the changes of velocity of two shot putters’ body in the throwing process with high speed vidicon.The results show that the speeds of the body’s gravity center and chests between two shot putters are different.The index of the speed increasing has been made for the segments of the body during the throwing process.更多还原
