长跑是典型的耐力项目,虽然强度较小,但由于距离长,相对于其他项目来说量仍然是很大的,因此在长跑训练中合理地安排好运动量的问题就更显得重要了。从五十年代起世界各国普遍地推广了大运动量训练。二十多年的实践证明:大运动量训练确实是提高运动成绩的最有效手段之一,它的生理根据就是强度大、密度大、时间长的练习能引起机体强烈的反应。在大运动量训练中,肌肉活动是在相 The long-distance race is a typical endurance project. Although the intensity is small, the distance is longer than any other project, so it is even more important to rationally arrange the amount of exercise in the long-distance running training. Since the 1950s, various countries in the world have generally promoted large amount of exercise training. More than two decades of practice have proved that the training of large amount of exercise is indeed one of the most effective ways to improve the performance of sports. Its physiological basis is that the practice of intense intensity, large density and long time can cause a strong reaction of the body. In large amount of exercise training, muscle activity is in phase
