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。

Abstract:: 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 125kg 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 0.08s, 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.
