我国优秀女子铅球运动员过渡阶段技术的运动学分析

The KinematicAnalysis on Transition stage Technique of Elite Female Shot- Putters of

选定进入2011年全国田径大奖赛(苏州站)女子铅球决赛前8名的运动员滑步阶段技术作为研究对象,研究结果显示:研究对象在过渡阶段左脚积极压插着地不够,过渡阶段时间较长,左脚落地瞬间躯干前倾角和左肩后倾角偏大,左臂打开较早,影响了身体扭紧程度,过渡阶段超越器械效果不理想。过渡阶段8名运动员左脚着地瞬间的左膝角偏小,左脚着地瞬间左侧支撑制动效果欠佳。

Selected in 2011 national track and field competition （Suzhou Railway Station） women＇s shot put final top 8 players sliding phase technology as the research object, the results showed： the research object in the transition stage of left foot inserting enough positive pressure, phase transition time is longer, left foot hits the instantaneous anterior trunk inclination angle and left shoulder, left open earlier, affect the body tightening degree, transitional stage beyond the equipment effect is not ideal.Phase transition of 8 athletes left a moment left knee angle is small, the left with the left support of poor braking effect.
