At the gliding stage,LI Ling angel of thigh and ground is much big,the swing legs vertical speed too high,level speed too smell and the enlarging angel of body gravity; At the transitional stage,the transitional time is long,velocity of body gravity and shot gravity descend;The supporting point of LI Ling is prominent,speed-up effect is striking at the ending movement stage.
结论:李玲在起滑时蹬地角偏大,左腿摆动垂直分速过大,水平分速相对较小,重心腾起角增大;过渡步阶段单支撑时间过长,铅球速度和身体重心速度均呈现下降趋势;最后用力阶段主要加速点(用力点)较为突出,加速效果较显著。
