The weather is getting warmer and warmer, and many people want to get rid of the "fat" raised in winter through sports and fitness. Recently, the "sweat suit" that claims to be able to sweat quickly and accelerate calorie consumption has been screened on major social platforms, and even appeared on elevator advertisements in some communities, attracting the attention of some weight loss groups and fitness enthusiasts. So, is the "sweat suit" really that magical? Is sweating equal to losing weight?

The "sweat suit" advertised in the elevator advertisement is very attractive. On some social platforms, reporters saw that some "sweat clothing" products claimed to use "thermal control silver technology", which can increase body temperature, activate sweat glands, and promote sweat discharge in a short period of time. The advertisement claims that you can sweat profusely and burn more calories after wearing it for 10 minutes.
Qiu Jianxing, a fitness person, said: "It is definitely useful, but it is more likely to reduce water, and it is water that evaporates." It is estimated that it is not good to reduce fat and fat. ”
Fan Sicheng, a reporter from Jiangsu Tv, said: "Now I am wearing the so-called 'violent sweat suit'. The sweat jacket label reads 100% polyester with a silver coating on it. Wearing such clothes feels that there is some warm effect, and you can indeed sweat a lot after exercising for a while. But does this sweating mean real fat loss? ”
【Rehabilitation medicine experts: rapid sweating and weight loss is not equal to fat loss】
Experts related to rehabilitation medicine told reporters that the breathability of the "sweat suit" is relatively weak, and the principle is similar to "running with plastic wrap wrapped around the body", which mainly plays a role in rapid perspiration. Some athletes use it to reduce weight for a short period of time before a game, but they can't really lose fat.
Ma Ming, deputy director of the Department of Rehabilitation Medicine at the Zhongda Hospital affiliated to Southeast University, said: "The reaction of sweating in a short period of time causes the body to lose water, resulting in short-term weight loss. Go back and drink some water and replenish it. But fat loss is achieved through exercise to achieve a certain exercise intensity to really start to consume fat. ”
【Fat loss needs to be insisted on for more than 3 months, exercise to achieve medium and high intensity】
Experts say that blindly seeking speed is often contrary to fat loss. In general, after 20 to 40 minutes of aerobic exercise, fat consumption begins. If you want to lose weight, you need to insist on exercising for more than 3 months, and the frequency is about 3 times a week. Of course, a certain exercise intensity should also be guaranteed.
Ma Ming said: "The intensity of exercise in medium and high intensity can achieve real fat mobilization and fat loss. Strength in general we have a formula, 220 minus the age of the individual multiplied by 70% to 80%. This is the heart rate that we should normally maintain during exercise. At the age of about 40 years old, the exercise heart rate should be at least about 150, and it can be maintained for more than 20 minutes to achieve the purpose of real fat loss. ”
Experts recommend that indoor fitness should choose cotton and sweat-absorbing clothing with good breathability. Outdoors, you can wear some quick-drying, thermal insulation and other functional materials.
