我国优秀女子铅球运动员滑步阶段技术的运动学分析

摘要

Selected in 2010 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 at the gliding stage swing leg movement coordination, a right pedal ground instant take-off angles are relatively large, left leg swing high, two thigh angle is small, the body's center of gravity fluctuation effect of human - ball system, the overall effect; research object sliding stage top speed of swing leg are appeared in the right foot off the ground before, namely in the right leg active push-off phase; the sliding time longer, and the world elite athletes gap; sliding in upper body lift larger, affected the trunk twisting degree and beyond equipment quality of movement.%　　选定进入2010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：研究对象在滑步阶段摆蹬动作协调，右脚蹬离地面瞬间蹬地角偏大，左腿摆动偏高，两大腿间夹角偏小，身体重心起伏较大，影响人—球系统的整体效果；研究对象滑步阶段左腿摆动最高速度均出现在右脚蹬离地面之前，即在右腿积极蹬伸的阶段；滑步时间稍长，与世界优秀运动员相比存在差距；滑步中上体上抬较大，影响了躯干扭紧程度和超越器械的动作质量。
