China News Agency reporter Xing Chong
As China's domestic epidemic prevention and control situation improves, resumption of work, resumption of production, and resumption of school gradually advance, sports safety has become a major focus of public concern. The two recent events of sudden death of students wearing N95 masks have caused a heated discussion about whether to use sports masks. In an interview with a reporter from China News Service, industry insiders called for this move to be cautious, and to distinguish the occasions and master the "degree".
Modern medicine divides sudden death into "sudden cardiac death" and "sudden cerebral death". The former causes death within a short period of time due to sudden cardiac arrest. There are many predisposing factors, including long-term stay up late, strenuous exercise, excessive fatigue, etc., weather The heat also increases the risk. Most of the sudden deaths in marathons that have occurred before are mostly due to high-intensity exercise leading to increased oxygen consumption in the heart of runners, resulting in myocardial damage.
Li Xuemei, a teacher at the School of Sports Medicine and Rehabilitation of Beijing Sport University, told reporters from China News Service that the air resistance of people breathing after wearing a mask will increase, which is equivalent to artificially placing a burden on their own respiratory muscles and the risk of sudden death during physical exercise Will increase accordingly.
"During vigorous exercise, our breathing is deepened and accelerated, which is already very laborious. After wearing the mask, we actually increased breathing resistance. This resistance is not only due to the decrease in each time we ventilate, but also in the respiratory muscles. The burden has increased. "Li Xuemei said, coupled with the" home "during the epidemic caused a decline in heart and lung function, so it led to an increased risk of sudden death.
However, some people in the industry said that the movement of wearing masks is a "helpless move" under the epidemic. The important thing is to grasp the "degree".
"When you feel that your body is beginning to pant and have difficulty breathing, you will immediately take off the mask and reduce the intensity. Do not increase the intensity again, so that you can avoid a lot of physical discomfort." Co-founder of Nasia Physical Rehabilitation Center, Pan Lei, fitness trainer and appraiser of the State Sports General Administration.
Pan Lei also specifically mentioned that if you want to do strength training in the gym, you can wear a mask for safety reasons. "Similarly, you need to master the intensity, don't do high-intensity training in the gym, because high-intensity, high-strength training will cause shortness of breath and require more oxygen."
He also suggested that the gym must be well ventilated, and fitness enthusiasts should also maintain a certain distance during equipment training.
As the risk level of outbreaks in various parts of China declined, people began to gradually go out indoors and begin outdoor sports. Experts suggest that fitness exercise should also gradually transition from low-intensity exercise to normal physical exercise.
"In places with few people, we can take off the mask for continuous running or cycling. In places with more people, it is recommended to wear a mask to reduce the risk. You can do sports with shorter time and less intensity, such as squats, for a short time. You can complete two or thirty, and the impact on breathing is not too great. "Li Xuemei said.
Pan Lei also believes that although outdoor fitness venues are gradually being liberalized, it is currently recommended to combine indoor and outdoor sports. "As long as the method is appropriate, you can exercise at home and in the community. For outdoor sports, try to choose a place with few people when the weather is good, jog or simple strength exercises."
Under the epidemic, many people have also paid more attention to their health. Experts suggest that, whether indoor or outdoor, exercise and fitness is a lifestyle that needs to be maintained for a long time, and the amount of exercise cannot be increased or decreased significantly due to changes in the environment.
"If you didn't have regular exercise habits before or during the epidemic, and now you feel that you need to start exercising outdoors, you suddenly start high-intensity exercise, which is not recommended." Li Xuemei said that this move may even cause a temporary decline in immunity With the risk of virus infection, people still need to control the time and intensity of physical exercise in the current situation.
