摘要
为探寻优秀运动员抓举技术特征,运用三维运动学的方法对参加2013年全运会举重比赛运动员龙清泉抓举125 kg技术进行研究。结果表明:在提铃开始阶段先伸膝后展髋熟练掌握了正确的提铃技术;引膝阶段耗时0.08 s,膝关节仅回屈3 Deg,这一特征与传统引膝技术已有明显区别,且在不同优秀运动员身上反复出现,应引起重视;独特的引膝技术导致正反两方面的影响:反面影响为人杠重心间距偏大,正面影响为发力连贯性较好,杠铃速度提升比较大。发力阶段髋、膝关节角度变化一致且同时达到最大值,体现了优异的发力协调性。
In order to find the snatch features of the excellent athlete,using the three-dimensional kinematic approach to participate in 2013 National Games weightlifting competition athletes 125 kg snatch Long Qingquan technology research. The results showed that： at the beginning of the first exhibition of the hip extensor mastered the correct technique to mention the bell;reduce knee consuming stage 0. 08 s,Knee flexion 3Deg back only to 108. 4Deg,reduce knee with traditional techniques are quite different; force stage hip and knee angle changes consistent and reaches its maximum at the same time,reflects the superior force coordination.
