对我国优秀铅球运动员过渡阶段相关运动环节及铅球的速度节奏进行了生物力学分析与研究,结果表明:运动员身体重心和铅球运动速度曲线在过渡阶段的分合对提高运动成绩有重大的作用;过渡阶段摆动腿快速落地缩短单支撑时间是尽快形成双支撑进入最后用力的关键;我国优秀铅球运动员在双支撑前便开始最后用力,有待于提高向下运动的抗冲击负荷的能力。 The results of the biomechanical analysis and research on the speed rhythm of the elite shot putter during the transitional phase and the speed of the shot put the results show that the division of the athlete’s body center of gravity and the speed of shot during the transitional phase plays a significant role in improving the performance of the athlete. Stage swing leg quickly landing to shorten the single support time as soon as possible to form a dual support into the final force; the best shot put athletes in China before the double support began the last force, to be enhanced in the ability of downward impact resistance load.
