一、前言在运动训练中,怎样选择适宜的运动强度,以提高训练效果和运动成绩,这是体育界一直所关注的问题。当前训练负荷发展的总趋势是越来越重视训练强度。加拿大学者博南曾明确指出:“在负荷诸因素中,训练强度为其首,训练次数为其次,训练时间或训练总量为其末。”由此看来,训练强度是运动训练的关键。我国田径运动中,400米跑成绩落后的主要原因之一可能是训练方法不佳。400米跑是速度耐力项目,运动强度过大过小都达不到预期的训练效果。而以往训练中,可能只强调了运动量而对选择适宜的
First, the foreword In sports training, how to choose the appropriate exercise intensity, in order to improve the training effect and the athletic achievement, this is the sports profession has been the concern question. The current trend of training load development is more and more emphasis on training intensity. Bonanne, a Canadian scholar, has made it clear that “among the load factors, the training intensity is the first, the training frequency is the second, and the training time or the total training is the last.” Therefore, training intensity is the key to exercise training. One of the main reasons behind the 400-meter run in track and field in China may be that the training methods are not good. 400 meters run speed endurance project, exercise intensity is too small to reach the expected training effect. In the past training, may only emphasize the amount of exercise on the choice of appropriate
