目的:对女子举重运动员杨梅抓举技术动作进行分析,试图寻找技术上存在的不足之处,为教练员提供建议。方法:本研究使用2台德国HSVISION公司Speed Cam Macro Vis Eo Sens高速相机对运动员的抓举技术动作进行拍摄,对获取的动作视频采用SIMI-motion三维运动分析系统进行分析。结果:伸膝提铃阶段和引膝提铃阶段杠铃加速度曲线较紊乱。在伸膝提铃阶段由于用力不合理导致杠铃速度出现下降现象。在发力阶段的发力效果较好。结论:运动员的用力节奏较差,抓举技术水平的精细化程度有待改进。
OBJECTIVE: To analyze the technical action of the women weightlifter Yangmei in the snatch and attempt to find the technical deficiencies and provide advice to the coaches. Methods: The athlete’s snatch technique was shot using two Speed Cam Macro Vis Eo Sens high-speed cameras from HSVISION, Germany. The acquired motion video was analyzed by SIMI-motion three-dimensional motion analysis system. Results: The curves of barbell acceleration in knee extension and knee lifting were disordered. In the knee extension stage due to irrational barbell speed led to decline. Force in the stage of force is better. Conclusion: The rhythm of athletes is poor, and the level of sophistication of snatch technique needs to be improved.
