在投掷教学的最初阶段,学生不能掌握正确的技术动作,仅靠手臂的力量投掷器械,动作既不美观,又影响了运动成绩,这是一个非常普遍而又较难解决的问题。我在刚开始从事教学工作时,也曾为此烦恼,后来经过钻研教材教法,多方请教,对学生投掷动作进行认真细致的观察,又在教学工作中反复实践,不断探索,最后发现问题出在学生进行投掷练习时,没有全身协调用力。另外,运动营养品在训练过程中的合理使用,是我们取得良好的训练效果的基础保障,对于提高学生的身体素质和训练后的恢复也有促进作用。因此本文将先浅谈投掷项目的协调用力,然后结合运动营养补充手段,阐述如何对投掷项目进行科学化训练。 In the initial stage of throwing teaching, students can not grasp the correct technical actions. Throwing instruments by the strength of their arms is neither aesthetically pleasing nor affecting sports performance. This is a very common and difficult problem to solve. When I was first engaged in teaching, I had to worry about this. Later, after studying textbooks and teaching methods, I consulted with each other for careful and careful observation of student throwing movements. I repeated my teaching practice and continued to explore and finally found problems There is no general body coordination when students are throwing exercises. In addition, the rational use of sports nutrition in the training process is the basic guarantee for us to obtain good training effect, which also has the promotion effect on improving students’ physical fitness and post-training recovery. Therefore, this article will first talk about the coordination of throwing force, and then combined with sports nutrition supplements means to explain how to throw the project for scientific training.
