每个教练对于训练都有自已的一套计划。他们对训练课的计划、分析和理解以及各人的经验形成了一套训练体系。随着训练方法的不断改进,训练体系也不断变化。现代中跑训练中所采用的几种方法值得我们探讨,能为深入了解现代训练方法提供依据。尽管训练学中还不能确述决定人类工作能量的精确指标和具体原因,但也已了解了许多人类对运动的需求。提出了决定人类运动能量的三个主要因素:(一)对氧气的需求。身体运动需要氧,运动愈剧烈,需氧量愈大。(二)供氧不足。当运动量加大,需氧量超过了人 Each coach has its own set of plans for training. They formed a training system for the planning, analysis and understanding of training sessions and the experience of each individual. With the continuous improvement of training methods, the training system is also constantly changing. Several methods used in modern middle distance training deserve our discussion, which can provide a basis for further understanding of modern training methods. Although the precise indicators and specific causes that determine the energy of human work can not be defined in training, many human beings are aware of the need for exercise. Three major determinants of the energy of human movement are proposed: (i) the demand for oxygen. Physical exercise needs oxygen, the more intense exercise, the greater the oxygen demand. (B) lack of oxygen. When the amount of exercise increased oxygen demand over the people
