本文作者认为中国体能类项目落后的主要原因不在于“遗传、训练条件和训练的具体手段”等问题,而是缺乏科学训练的理念,在训练方向和指导思想方面没有跟上世界的发展。本文着重阐述了运动训练的生化基础,强调了训练必须遵循生物适应的原则,提出“最大的训练负荷并不能获得最佳的适应,适应的‘最佳’区域肯定位于运动员可承受负荷之下” The author believes that the main reason for the backwardness of China’s physical fitness programs lies not in the issues of “inheritance, training conditions and specific training methods”, but also the lack of scientific training concept and the failure to keep up with the world in terms of training direction and guiding ideology. This article focuses on the biochemical basis of exercise training, emphasizing that training must follow the principle of biological adaptation, that “the maximum training load and can not get the best adaptation, adapted to the” best “region is certainly located under the athletes can withstand the load”
