铅球出手力学问题的分析

On the Mechanics of shot Putting

推铅球是一个速度力量性项目,是以力量速度为基础,以速度为核心的田径投掷项目。尽管优秀运动员所采用的投掷技术存在一定的差异,但决定投掷远度的主要因素是共同的。包括出手高度、出手角度以及出手的初速度三个方面的因素。文章通过对这三个因素的力学分析,为铅球的训练提供了有力的理论依据。

Shot put ?a throwing event requiring speed and physical strength ?has the physical strength as its basis and the speed as its core. The exellent sportsmen have some different technique in throwing, but the decided factors are common. These decided factors include the height of the throwing, the degree of the throwing. By analysing the three factors, the thesis provides powerful theoretical basis for the training of shot putting.
