人体在激烈运动时,肌肉能量需求比安静时增加约120倍,为了满足运动时的能量需求,使得某些代谢过程在激烈运动时十分重要,甚至占支配地位,如200米跑,95%左右的能量来自无氧代谢。众所周知,人体组织细胞中包含有氧和无氧两个体系,包括三个供能系统,即磷酸原供能系统(ATP-CP系统)、无氧糖酵解供能系统、有氧氧化供能系统。这三个供能系统并不是各自独立的,而是紧密相联、互相协调、共同组成的一个完整能量供应体系。供能系统供能能力强弱,决定着运动水平的高低。因此,教练员在制订训练计划时首先应明确所训练的运动项目、专项中主要的供能系统,然后选取科学的训练方法,发展该系统的供能能力。
In intense exercise, the muscle energy requirement is increased about 120 times than that of quiet. In order to meet the energy requirement during exercise, some metabolic processes are very important and even dominate in intense exercise such as 200-meter running and about 95% The energy comes from anaerobic metabolism. As we all know, human tissue cells contain two systems of oxygen and anaerobic, including three energy systems, namely, phosphate power supply system (ATP-CP system), anaerobic glycolysis power supply system, aerobic oxidation system. These three systems are not independent of each other, but closely linked, coordinated and co-formed a complete energy supply system. Power supply system for energy capacity, determines the level of exercise. Therefore, coaches should formulate the training plan first clear the training of sports, special projects in the main energy system, and then select the scientific training methods to develop the system’s energy supply capacity.
