摘要
就我国优秀女子铅球运动员的最后用力技术作为研究内容,对其进行定量的运动学研究。结果表明:我国优秀女子铅球运动员最后用力的顺序基本正确,右髋转动合理有效;但是,左膝角偏小,缓冲过大,造成左侧支撑不理想,铅球运行距离短,影响了髋部和身体重心的侧移,在一定程度上影响了"人—球"系统的速度叠加和动量的传递。从而,导致出手条件不理想,影响了专项成绩。针对上述问题,提出一些改进建议。
This article conducts a quantitative kinetic research on the final strength - exertion technique of our talent women＇s shot - putters. Research findings indicate that the sequence is basically right and right hipbone maneuvers are effective, but the left knee angle is a little bit small and room for maneuvers is too much,which results in unsatisfactory left side prop, short distance shot travel and affects maneuvers of hipbone and body weight center. Thus the performance is hindered. Suggestions to improve this situation are also proposed.
