摘　　要：以多哈亚运会女子铅球冠军李玲为研究对象,研究其背向滑步技术不同阶段下肢速度节奏特征。结果表明:滑步阶段人体重心与铅球的速度有明显上升趋势,与其它优秀运动员相比重心速度与铅球速度差值过小;过渡阶段较好地保持了人体重心速度和铅球速度;最后用力阶段人体重心速度下降过大,对铅球最后加速产生不利影响。By basing her study subject on LI Ling, women shot put champion in Doha Asian Games, the author studied the rhythm and characteristics of lower limbs moving speed at different stages in the backward step gliding shot put putting technique of LI Ling, and revealed the following findings： at the step gliding stage, LI Ling＇s moving speed of body center of gravity and the shot put was increased significantly, but compared with other excellent athletes, the difference between the speed of the center of gravity and the speed of the shot put of LI Ling is too small; at the transition stage, LI Ling maintained a good speed of body center of gravity and the shot put; at the final power exploding stage, LI Ling＇s speed of body center of gravity dropped too fast, which produces an adverse effect on final acceleration of the shot put.
