从投掷技术原理来讲， 器械飞行的远度主要取决于出手初速度， 而最后用力阶段是其获得速度的主要来源。为适应现代推铅球技术的发展， 文章扼要地提出最后用力开始的时机， 分析影响最后用力效果的因素， 并针对性地提出改进最后用力效果的途径， 对铅球最后用力阶段在技术和理论方面做点滴补充。 From the principle of throwing technology, the distance of the instrument flight mainly depends on the initial speed of shot, and the last force phase is the main source of its speed. In order to adapt to the development of modern shot put technology, this article briefly puts forward the timing of the final force start, analyzes the factors that affect the final force effect, and puts forward the ways to improve the final force effect in the technical and theoretical aspects of the final stage of shot put Drip supplement.
