不同重量铅球训练法的实际运用

不同重量铅球的训练法对于铅球运动成绩的提高起着重要的作用。铅球运动员三种不同的技术类型是运动训练中不同重量铅球施用的客观要求：“负荷——应激力”的原理是轻、重铅球重量确定与选择的生理学基础：铅球项目的专项速度与专项力量是确定轻、重铅球训练比重的根本出发点;空心铅球的采用是不同重量铅球训练的变式。

Actual Exertion of Training Method for the Different Weight Shots

It is important to improve the performance of the shot for the training method of the different weight.Three different technical models of the thrower are the objective requirement for the esertion of the different weight shot in the athletic training;the principle of the "the burden-stess"is a physiological basis of the selection of lightweight shot;the specific velocity and strength of the thowing event are the starting point of setting the proportion of lightweight shot;the adoption of the hollow shot is the alternative form of the training of the different weight shot.
