摘　　要：通过运动学分析方法对我国参加2008年北京奥运会的3名优秀女子铅球运动员最后用力技术进行分析。结果认为,巩立姣有右肘关节提前用力的不合理现象;李玲超越器械和左侧支撑技术不好,左脚的着地方式不合理,最后用力的幅度小、距离短,向前性不好;李梅菊左腿蹬伸不积极,腿部力量薄弱。By using the method of kinematics, the last exerting technique of three Chinese elite female shot throwers who take part in the 2008 Beijing Olympic Games are compared and studied. The result shows that there is a pre-exerting unreasonable phenomenon in GONG Li- jiao＇s right elbow. LI Ling is exceeding equipment and left supporting is not good, the landing way of her left foot is unreasonable, the last exerting range is small, the distance is short and the forward is not good. The stretch of LI Mei-ju＇s foot is passive, and the power of her foot is weak.
