Sole socks made of nylon or spandex keep their original elasticity and shaping properties. But nylon is easy to break, and it is common to scratch and break on sharp objects. Cotton-wool blended bottomless socks have better warmth retention effect.
The top (waist) of tights is very elastic. The part that covers the hips is thicker than the legs (except for some dance purposes). The crotch bottom is also a solid material, usually cotton, which can keep the genitals cool. Legs and feet, all the way to ankles, are made of the thinnest weave.
Fitness, wearing tights is really necessary.
Some people say that wearing loose clothes is very comfortable.
But functionally speaking, it is better to wear tights.
this is because
First: Wearing tights can reduce muscle fatigue during exercise. Because wearing tights can accelerate blood circulation and lactic acid metabolism and reduce lactic acid accumulation, and tights with high tightness are better than tights with medium tightness.
If you are a little fat, tights will do you more good.
Because the most terrible thing in sports may not be the impact force, but the * * * vibration caused by physical impact, the fatter friends are particularly vulnerable to the * * * vibration. The * * * vibration frequency of fat is very close to that of articular cartilage. The greater the volume and weight of fat, the stronger the effect of * * * vibration. At this time, tights can effectively help you reduce vibration.
Second: Tights can also help you keep the best temperature for muscle exercise and speed up the process of body temperature regulation during exercise … and so on, with many benefits. So it is necessary to wear tights to keep fit.
Third: it looks good. Commonly known as pack to force. For men, high-elastic tights can show a strong figure and provide personal comfort. For girls, tights can also show the curvaceous beauty of women as much as possible.

It is said that drinking coffee before exercise is good for reducing fat. Is it true?/You don't say.
Coffee can significantly increase energy consumption and fat consumption during exercise! Griffith University in Australia and the University of Queensland once published a study, in which they tested the energy consumption and fat consumption in three situations: coffee+exercise, simple exercise and no coffee and no exercise.
The exercise in the experiment is an hour's riding. The results show that drinking coffee and exercising have a prominent effect on consuming energy and fat.
As can be seen from the figure, the experimental group consuming coffee consumes about 250 kilojoules of calories and 10g of fat more than the experimental group simply exercising without drinking coffee, and the effect is very obvious! Moreover, the study also found that coffee reduced the overall training difficulty and increased the pleasure of the trainers. Drinking a cup of coffee before exercise can improve blood circulation, better deliver oxygen to all parts of the body, improve muscle function and increase exercise effect.
Drinking coffee after exercise increases fat consumption. Some studies have compared the differences of EPOC between caffeine intake and placebo before and after exercise. The results showed that the EPOC of caffeine group was significantly higher than that of placebo group within 3 hours after exercise.
(PS: EPOC means that during exercise, the sugar you owe will return to your body in the form of fat after exercise)
How to drink is effective?
Although drinking coffee before exercise is good for exercise, don't exercise immediately after drinking coffee. Because caffeine will be completely absorbed by the human body after drinking coffee for 40 minutes, exercising after drinking coffee for 40 minutes can better play the role of drinking coffee. You should also pay attention to the amount of coffee you drink before exercise, not the more the better. 1 2 cups is enough.
Don't drink coffee while exercising. Caffeine has no time to play an active role, but it will block specific receptors on the blood vessel wall, hinder blood vessel expansion, reduce myocardial blood flow, affect oxygenation in the body, and make you unable to get enough energy during exercise.
You need to supplement nutrition after exercise, and coffee is a good tonic. A research report published in the United States pointed out that drinking coffee can help people relieve muscle pain caused by excessive exercise, and drinking caffeinated mixed drinks after exercise can accelerate the recovery of the body. When the exercise is over, you can have a cup of coffee or a caffeinated drink.
Ps: If you exercise at night, it is not recommended to drink coffee after exercise, which will affect your sleep.
