800米跑速度的快慢取决于运动员身体能量供应的快慢,能量供应能够满足高速奔跑的能量的需求,就能创造优异成绩,能量供应不上,速度降低是自然的事情。其实我们平时的训练,无论是力量训练、速度训练,还是有氧耐力及速度耐力,其本质都是为了提高运动员奔跑时的能量供应,因此,800米的训练计划制定及训练方法手段的实施,都应紧紧围绕如何提高运动员的能量供应来设计。 The speed of 800 meters depends on the speed of athletes body energy supply, energy supply to meet the needs of high-speed running energy, you can create outstanding achievements, energy supply, speed is a natural thing. In fact, our usual training, whether it is strength training, speed training, or aerobic endurance and speed endurance, its essence is to improve the energy supply of athletes running, therefore, 800 meters of training programs and training methods and means of implementation, Should focus on how to improve the athlete’s energy supply to design.
