日本著名田径教练、生理学家金原勇教授曾通过多次实验得出结论:“长距离项目非常需要有氧耐力,这与呼吸、循环器官的发达情况有关。而呼吸、循环器官发达好坏,几乎与身材大小、肌肉发达好坏无关”。我们知道中长跑运动员仅发展肌体耐力素质,而忽视心肺功能的训练,是很难成为优秀运动员的。我在多年的训练实践中,观察到许多游泳运动员良好心肺功能事例,并从中得到启示:游泳是促进内脏功能发展的很好运动。于是,我在青少年中长跑课余训练中,安排了一定比例的大运动量慢游与短距离大强度快游的游泳训练内容,以求促进运动员心肺功能的发展。 Japan’s famous track and field coach, physiologist Kim Won-yong, Professor has been through several experiments concluded that: "Long-distance projects are in need of aerobic endurance, which is related to the development of breathing, circulatory organs related to the well-developed breathing and circulatory organs, almost And body size, muscle development has nothing to do. We know that long-distance runners develop only the endurance capacity of the body, while neglecting cardio-pulmonary training is hard to be a good athlete. During many years of practice, I observed many good examples of cardiopulmonary function in swimmers and learned that swimming is a good exercise to promote the development of visceral function. As a result, I spent a lot of time in the training of young people in long-distance running, arranging a certain proportion of large amount of exercise slow swimming and short-distance intensive training of fast swimming in order to promote the development of cardiovascular fitness.
