汗水总是锻炼的体现,也是它成功的标志。20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,并且每周要这样锻炼3-7次。随后的20年中,运动生理学家一直在制造数据来确证教练对锻炼者每次训练说的话:不努力,无收获。有氧健身的原则启发了一些人,但却让大多数人感到泄气。某些专家也曾经告诫人们,长时间的持续锻炼是非常重要的。然而现在看来,汗水并不是唯一的答案。实际 Sweat is always the embodiment of exercise, but also a sign of its 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 a week. For the next 20 years, sports physiologists have been making data to confirm what coaches say to exercising each training: no hard work, no gain. The principles of aerobic fitness inspire some people, but most people feel discouraged. Some experts have also warned people that long-term continuous exercise is very important. However, it seems that sweat is not the only answer. actual
