Improper indoor fitness in winter is easy to hurt the body.
1, indoor fitness is easy to be invaded by bacteria
When bodybuilders use fitness equipment, they will have a large area of physical contact with the equipment. Wearing a single hail during fitness will leave sweat stains and bacteria on the equipment. Some bacteria will spread when the next person touches the instrument. However, people breathe faster and their pores open during exercise, which makes them more vulnerable to bacterial invasion.
2. Indoor fitness air is turbid and breathing is difficult.
Because you consume a lot of physical strength, you need to breathe a lot of fresh air and emit a lot of carbon dioxide. Especially in gymnasiums, if there is no good ventilation equipment and convection device, it will lead to the continuous circulation of exhaust gas in a limited space.
What should I pay attention to in indoor sports in winter?
1, add carbohydrates in time before exercise.
Carbohydrate and protein should be supplemented in time before and after exercise, such as pasta, oatmeal, sweet potato, potato, chicken, eggs, lean meat, fish and bean products. And fruits and vegetables should also be in moderation.
2. Warm up before fitness.
Warm-up for fitness in winter is very important, and the warm-up time should reach 15 to 20 minutes, especially for equipment training to avoid muscle strain and joint sprain.
3. Open the window regularly for ventilation.
It is advisable to ventilate for 20 minutes three times a day in the morning and evening. Although some cold air will be put into the window in winter, experiments show that every breath can remove some harmful gases from the indoor air.
4. The exercise time in cold weather should be adjusted.
In winter, young people's basic metabolism is faster, and their physical functions recover faster after exercise in the morning or at noon, which will not affect their daily life. It is suggested that the exercise time can be set at 7:00-9:00 in the morning or at noon 12- 14. However, middle-aged and elderly people, because of their poor adaptability, are advised to improve their cardiopulmonary function, and the best exercise time is 18-20:00.
