| 摘 要： | 本研究运用高速摄影和影片解析法对我国优秀女子铅球运动员背向滑步推铅球技术进行分析，获得大量有价值的图表和速度曲线。经研究发现：滑步阶段左腿的有效摆动能加大右腿蹬伸力量，提高蹬伸速度，提高滑步速度，加快境速有利于身体重心速度的加快；在过渡阶段，加快右髋的快速前移，不仅有利于保持身体重心速度，同时有利于最后用力姿势的形成；摆动腿快速落地缩短单支撑时间，是尽快形成最后用力姿势的关键。

| Abstract: | The author tested the shot putting technique of elite female shot putters with high speed camera in some competitions, and gained many valuable curves and data. Analytical results show: Swinging motion and heavy support of the left leg are the keys to shot putting results. The quick movernent of right hip helps increase the velocity of moving centre of gravity and form the last thrdring gesture. All these will provide the valuable teaching and training theory for shot put in future. |
