人们一向认为每进行一次体育锻炼,就要一气完成规定的数量,而且认为完成的量越多越好,认为这样做才会效果显著。所以,有些时间少的人或没有长时间空闲的人,就无法锻炼。日本学者戎利光在美国布里汉·杨大学和美国一基金会支持下,就这个问题进行了实验,结果证明,只要跑时能保持一定的强度和频率,即使把规定的距离分在不同的时间里跑,也照样有相同的锻炼效果。研究结果发现:只要受训练者以同样强度和频率跑完同样距离(B组和C组有意把一天的距离分开来跑,但仍把它视为频率),并假定分开跑的最短时间足够激发心血管耐力的发展,那么虽然把跑的距离分开来跑,各实验组成员的心血管功能和血脂得到的效益在统计学上并无什么不同。 People always think that once every physical activity, we must accomplish the specified quantity angrily, and think that the more the better, the better. Therefore, some people with less time or people who do not have a long time can not exercise. The Japanese scholar Rongliangguang, supported by the United States of America Brigham Young University and the U.S. Foundation, conducted experiments on this issue. The results show that even if the prescribed distance is maintained at a different intensity Time running, also still have the same exercise effect. The study found that as long as the trainee ran the same distance with the same intensity and frequency (B and C deliberately ran away from the day, but still considered it as frequency) and assumed that the shortest run apart was enough to provoke The development of cardiovascular endurance, then although the running distance to run apart, the experimental group members of the cardiovascular function and blood lipid obtained benefit is statistically no different.
