罗军投掷链球的三维分析

A Three-Dimensional Analysis of Luo Jun's Hammer Throwing

对掷键球的三维分析,国外正逐渐开展起来,但尚不普及。在我国,对此还没有人进行过。掷链球是一项十分典型的三维空间运动,只有通过三维分析,才能真实地反映链球运动的特点和规律。本文运用近景动态摄影测量方法,对罗军投掷链球进行三维分析,从而获得了有关的主要技术数据.这对改进其技术,改善运动训练具有一定的参考价值。

Three-dimensional(3D) analysis of hammer throwing technique has been seen in some countries, but in China it is still new to everyone. Hammer throwing is a very typical three-dimensional movement. Only by 3D analysis, can the Special features and regular patterns of the throwing be vividly revealed. By using close-range dynamic 3D cinematographmetry, this paper presented analysis of Luo Jun's throwing technique and some related important technical data, which will be of significance to the improvement of hammer throwing training.
