长期以来,400m跑训练应归属何类项目训练体系的问题一直存在着争议,造成了不少教练员对400m跑项目存在认识上的分歧,这已经成为相当一部分400m跑运动员成绩提高的主要障碍.为此,本文从运动生理学、运动生物力学等几个不同角度对200m、400m、800m跑项目作比较分析研究.旨在对400m跑训练应归何类训练体系的问题进行探讨,以求为提高我国400m跑的运动水平和今后的科学训练提供理论依据. For a long time, there has been controversy over what type of training system the 400m run training should belong to, causing many trainers to disagree about the 400m run. This has become a major obstacle for the performance improvement of 400m runners. For this reason, this article makes a comparative analysis of 200m, 400m and 800m runners from several aspects such as sports physiology and sports biomechanics, etc. The purpose of this paper is to discuss what kind of training system should be classified into 400m run training, Our country 400m running level and future scientific training provide theoretical basis.
