对2011年全国长投公开赛男子链球决赛进行三维摄像和解析,发现我国优秀男子链球运动员与国外优秀运动员相比在旋转及最后用力技术上还存在着巨大的差距,主要是在加速节奏、身体重心变化、单双支撑时间比、链球加速途径、链球方位角、链球运行斜面角以及旋转与最后用力的衔接等方面。本文针对我国优秀运动员所存在的问题,提出一些可行性的建议,为教练员及运动员的训练提供科学依据。
It is found that there is still a huge gap between the skills of the elite male hammer throwers and the elite athletes in the rotation and the last force in the final match of the 2011 National Open Championship, Change of center of gravity, single and double support time ratio, chain ball speed up the way, hammer ball azimuth, chain run ramp angle and the rotation and the last force of the convergence and so on. This article aims at the existing problems of elite athletes in our country and puts forward some feasible suggestions to provide scientific basis for the training of coaches and athletes.
