长久从来,人们总是从汗水为锻炼的要旨,也视出汗为锻炼成功的标志。上世纪70年代的有氧健身革命为剧烈运动添加了理论依据。科学家们说,要从锻炼中受益,必须将心率提高到最高心率的70%-85%,每次出汗20-60分钟,并且每周要这么锻炼3-7次。有氧健身的原则启发了一些人,但也让大多数人感到望而却步。然而现在看来,汗水并不是唯一的答案。 For a long time, people always sweat as the essence of exercise, but also sweat as a sign of exercise success. The aerobic fitness revolution of the 1970s added a theoretical basis to strenuous exercise. To benefit from exercise, scientists say, heart rate must be raised to 70% -85% of maximum heart rate, 20-60 minutes per sweating, and 3-7 times per week. The principles of aerobic fitness inspire some people, but also make most people feel discouraged. However, it seems that sweat is not the only answer.
