铅球投掷作为一项传统的田径运动,在技术上不断发生着变革。在铅球投掷技术的变革始终是为了追求最大的水平投掷距离,而铅球投掷的水平距离和力学有着密不可分的内在联系。针对对推铅球过程中物理量以其各量间的关系进行了探讨,将铅球出手前后分为两个独立的过程来进行分析。最后结合对推铅球的力学基础分析的结论,提出推铅球实践过程中的相关建议。
Shot putting, as a traditional athletics, is constantly changing in technology. The change in shot put technique has always been to pursue the maximum level of throwing distance, and the horizontal distance of throwing shot and mechanics are inextricably linked. In view of the relationship between the physical quantities in the process of shooting shot put, the relationship between the various quantities is discussed. The shot shot is divided into two independent processes for analysis. Finally, combining the conclusion of the mechanics foundation of putting shot put, the paper puts forward some suggestions in the practice of shooting shot put.
