摘　　要：采用遥感肌电结合影像解析技术,对旋转式推铅球运动员冯杰最后用力阶段准备部分时间顺序、用力大小及贡献率进行定量分析,改进问题并找出肌肉活动的内在动因。研究表明:右腓肠肌后段在最后用力阶段准备部分放电持续能力不足;右竖脊肌、左股二头肌、右腹外斜肌、右股二头肌放电持续时间较长;右腹外斜肌是最后用力准备部分的主要发力肌肉,对提高投掷成绩具有重要作用;在今后训练中要加强右臀大肌的快速持续放电能力。A quantitative analysis of the time series,the strength and the contribution rate of the outstanding rotary throwing athlete Feng Jie in the final exertion stage was done by using the technology of remote sensing electromyography combined with the image analysis.The aim was to improve the problems with Feng Jie in the final exertion stage of preparation and find the intrinsic motivation of muscle activity.The results show that the capacity of the right gastrocnemius muscle is insufficient in the final exertion stage and the discharge time of right erector spinae,left femoral biceps,right ventral oblique and right femoral biceps is longer.The right ventral oblique is the main force of the muscles in the final exertion stage and has a close relationship with throwing results.The exercise of right gluteus maximus continuous discharge capacity should be strengthen in the future training.
