1, warm-up activities should be sufficient. Cold climate, protective contraction of human organs and systems, decreased elasticity and ductility of muscles, tendons and ligaments, increased viscosity of muscles, reduced range of joint movement and low air humidity. If you exercise without doing warm-up activities, you will often cause muscle strain and joint sprain. Therefore, when doing fitness exercises in winter, especially outdoor sports, we should first warm up. After jogging, unarmed exercise and a small amount of light equipment practice, you can warm up your body, sweat a little, and then join the fitness exercise.
Increase or decrease clothes in time
2. To do fitness exercises in winter, first of all, you should wear more clothes, which should be light and soft, not too tight. After warming up, you should take off some thick clothes. After exercise, if you sweat a lot, you should dry your sweat in time, put on sweaty sportswear, shoes and socks, and wear a hat to prevent heat loss. Besides, when you exercise outdoors, you should pay more attention to keep warm. You will get hotter after exercise, and you always want to cool off, but you must not stand in a windy place to blow. Instead, go back indoors as soon as possible, dry your sweat and put on clean clothes. Therefore, it is particularly easy to feel cold feet when exercising outdoors in winter. If the head, back and feet are cold, cold air will invade the body from fur, nose and mouth, which will not only affect the effect of fitness exercise, but also catch a cold and get sick. At ordinary times, some fitness enthusiasts like to wear fitness shoes for winter, which is not good. Because rubber-soled shoes conduct heat quickly, the soles of feet are easy to catch cold when not exercising, leading to chilblain, arthritis and other diseases.
3. The environment should be comfortable. In winter, people are used to closing the windows of the gym tightly. As we all know, people exhale more than 20 liters of carbon dioxide per hour in a quiet state. If more than ten people exercise at the same time, one hour is more than 200 liters. In addition, the decomposition products of sweat and the bad gas discharged from digestive tract have caused serious indoor air pollution. Therefore, when exercising indoors, we must keep the indoor air circulating and fresh. In addition, in winter, it is not advisable to do fitness exercises in the yard filled with oil smoke and turbid air. At the same time, we should pay attention to the weather with poor climatic conditions, such as sandstorm, heavy snow or cold weather, and do not engage in outdoor sports for the time being. If you want to exercise outdoors, you should pay attention to choosing sunny and sheltered places.
