Whether you are a medical worker or a public servant at all levels or in all types of institutions who has been fighting against the new pneumonia, a teacher who has left school and is still teaching online classes at home, a primary school student who has stopped school and is trying to learn on his or her own, a worker who is still working at home and waiting to return to work at any time, or a close contact who is at home or in other isolated places for observation and treatment, I would like to say a sincere thank you. We would like to sincerely thank you for your hard work during this period. The most effective way to fight against the virus is to take a reasonable rest, strengthen your immunity, and do your personal protection. When it comes to strengthening the body, we all think of doing sports, how should we use the existing conditions for reasonable exercise? 1, choose the right sports ground Special period of the choice of sports ground, preferably at home or your isolated place, first of all, this is a more fixed space for your own (and family) life, compared to other places outside cleaner, safer; secondly, the type of exercise can be carried out in the above-mentioned place is already very rich, and with the help of furniture, home facilities have a lot (home has a treadmill and other exercise equipment Friends of this article can not refer to), can help exercise; and home exercise, the requirements of space is not very high, many exercise movements need but a yoga mat size of the place, of course, if the home space is very large, can also be some slightly interactive exercise; of course, exercise time is also more free, not affected by factors such as weather. For places that do not take the living area strictly closed management, no confirmed cases or suspected cases of the community, you can carry out appropriate exercise downstairs, but this we do not advocate, after all, there is a risk of going out, or be cautious. 2, arrange the appropriate exercise program The positive and negative impact of exercise on immunity has long been studied and many theories have been put forward, including the J-shaped model theory describes the relationship between regular exercise and the occurrence of upper respiratory tract infections, specifically: people who perform some moderate intensity or aerobic exercise have a lower probability of upper respiratory tract infections than those who do not or do not often play sports; however, the probability of upper respiratory tract infections in athletes who perform high-intensity sports training is lower than in people who do not or do not often play sports; however, the probability of upper respiratory tract infections in athletes who perform high-intensity sports training is lower than in people who do not or do not often play sports. The probability of upper respiratory tract infections was significantly higher in athletes who trained in sports. This tells us that moderate exercise (moderate intensity or aerobic exercise) can help the body to improve immunity and reduce the probability of respiratory infections. J-shaped model theory suggests that when we choose exercise, we can consider those shorter, within reach without increasing the burden of aerobics, yoga, etc. If there are higher requirements for people can then assist some local exercise movements to exercise, chest training such as: push-ups against the wall, push-ups, dumbbell bench press, etc.; abdominal training such as: abdominal rolls, flat support, supine air pedal bicycle, etc.; hip and leg can be hip bridge (with the help of a chair (can complete the high hip bridge), squats, stretching and other movements. The premise is that the right amount can be, do not let the body feel tired. Another study pointed out that a large intensity, prolonged acute exercise process or a small period of time after the exercise to activate the body’s immune function, but after the initial activation there will be a longer period of weakened immune function “window”, this time the body’s immune system many indicators to reduce the risk of infection may increase the body by the onset. Tips we should pay attention to the frequency of exercise that each exercise time, it is recommended that three times a week, each time 30-50 minutes is appropriate to enhance immunity at the same time, but also to effectively avoid sports injuries. 3, do a comprehensive personal protection (1) If you are at home for the corresponding exercise, and do not contact others, health status can not be confirmed when outsiders, you can exercise without a mask. (2) But when you go out to exercise when conditions allow, make sure to exercise with a good mask and avoid contact with any public facilities. (3) When exercising outside, try to go to a less crowded place and exercise alone, if there are other exercisers, the distance is better than 2 meters. (4) Wearing a mask to exercise outside would have brought a layer of obstruction to breathing, so it is more important to control the intensity of exercise to avoid breathing difficulties. (5) whether at home or outside exercise, we should pay attention to warmth, to avoid catching a cold, timely replacement of sweaty clothing is necessary. (6) Wash your hands promptly after exercise to avoid sweat contamination of items or touching other items that contaminate your eyes, nose and mouth. To fight the new crown pneumonia, you can exercise in moderation, please choose a suitable venue, bring a good mask to protect yourself, pay attention to warmth to prevent colds, and add clothes and clean your hands in time after exercise.
