体育科学的迅猛发展,必然导致训练方法上的改变。当前在世界高水平的运动员训练中,人们在训练方法和手段上,越来越重视坚持大强度训练了。 在世界体育运动发展史上,60年代和70年代是大运动量时期。统计数字表明,70年代末到80年代初,国际上高水平运动员所完成的运动量总数已达到和接近极限水平,以80年代和60年代相比,不少周期性项目的年训练量几乎翻了一番。例如中跑训练量从3000～5000公里增至6500～7500公里,训练次数从200～220次增至500～550次。我国的竞走和中长跑的训练量更是达到了周训练量220～240公里的令人惊异的地步。根据这些数字指标,人们要想再进一步提高训练量的可能性已不太大。所以,在数量指标基本稳定的基础上,为了促使运动成绩的继续提高,很自然,人们就把矛盾的焦点对准了如何进行系统 The rapid development of sports science will inevitably lead to changes in training methods. At present, people are paying more and more attention to intensive training in training methods and methods in high-level training of athletes in the world. In the history of world sports development, the 1960s and 1970s were periods of great athletic activity. Statistics show that in the late 1970s and early 1980s, the total number of athletes accomplished by international high-level athletes reached and approached the limit level. Compared with the 1980s and the 1960s, the annual training volume of many cyclical projects almost doubled Something. For example, mid-distance training increased from 3000 to 5000 kilometers to 6500 to 7500 kilometers, training times increased from 200 to 220 times to 500 to 550 times. China’s walking and long-distance race training capacity is reached a week training 220 to 240 km amazing. According to these figures, people are not likely to want to further improve their training. Therefore, on the basis of the basically stable quantitative index, in order to promote the continuous improvement of the athletic performance, it is natural that the contradiction has been focused on how to carry out the system
