摘　　要：以女子铅球运动员刘相蓉为研究对象,运用文献资料、走访、三维摄像解析和比较分析等方法对其滑步阶段的技术特征进行研究分析。研究得出,滑步时间应缩短到0.4 s,滑步距离加长到0.8m;铅球和身体重心的高度差降到0.2 m,增加大腿夹角110多度,保持滑步平稳。离地时右小腿与地面的夹角控制在60°以下,躯干倾角不要超过40°,可以降低身体重心垂直速度,增加水平速度。铅球最高速度与身体重心速度要保持一致,差值为0.1 m/s,后面阶段的水平速度才不会受影响。The sliding step technique of woman shot-putter Liu Xiangrong was studied. It was found that the sliding time should be shortened to 0.4 s and the sliding distance extended to 0.8 m. The height difference between the shot put and the body weight center should reduce to 0.2 m and the included angle between upper legs increase to more than 110°so as to maintain a smooth sliding. While the body lifted, the angle between the right leg and the ground should be controlled within 60° and the body inclination angle within 40°, thus the body weight vertical speed was reduced and the horizontal speed increased. When the highest speed of the shot put was the same as the speed of the body weight center, the horizontal speed of the later sliding step could maintain consistent.
