It absorbs sweat and breathes air. Many people wear pure cotton clothes when they exercise. In fact, pure cotton absorbs sweat very well, but its air permeability is poor. It's easy to get heatstroke when you wear it in summer, and it may make people catch a cold in autumn. It is suggested that both tops and underwear should be made of polypropylene with relatively good air permeability and moisture dissipation. It is light and safe. Don't wear tight and heavy clothes when exercising, mainly light. Otherwise, it will not only hinder exercise, but also cause unnecessary contusion or poor blood circulation. For example, to play basketball, the clothes should be loose and the neckline cuffs should be wide; When climbing a mountain, the trousers are elastic, thick and have large surface friction, which is beneficial to climbing and walking; When dancing square dance and aerobics, clothes should be elastic; When doing equipment exercise, you can choose elastic vest and loose shorts. It should also be noted that no matter what exercise you do, don't wear a belt. Choose shoes according to the amount of exercise. Different sports have different requirements for shock absorption, anti-slip and bending performance of sports shoes. When running, sports shoes must be light and strong in shock absorption, and the position of the forefoot should be elastic enough; There are many emergency stops when playing tennis, which requires good anti-skid performance of sports shoes; There are many bumps and jumps when playing basketball, so we should pay attention to the shock absorption function of shoes, wear high-top shoes to protect ankle joints and reduce the chance of spraining ankles; In indoor sports such as badminton, it is required to walk flexibly and choose lighter and more flexible sports shoes. In addition, some sports need special protective equipment. For example, when swimming, you should wear appropriate goggles and hats. The goggles can prevent the chemicals in the swimming pool from hurting the eyes, and the swimming cap can prevent ear shock and protect the head; Don't forget to wear a helmet when riding a bicycle, which can play a buffering role in the event of an accident and effectively reduce the external injury of the head; When pushing barbells and dumbbells, it is best to wear wrist guards and belts. I see, so in order to better ensure the effect of sports and avoid some accidental injuries, we should pay attention to the above principles when choosing sportswear and choose the most suitable sportswear.
