It Is Best Not To Exercise Vigorously While Wearing A Mask

Wearing a mask for exercise to prevent and control the epidemic, and then a sudden death occurred, people naturally associate the occurrence of sudden death with wearing a mask. So, do you wear masks during exercise, and what effect do different types of masks have on the human body? Some sports colleges have conducted experimental explorations and observed the difference between cardiopulmonary function performance at different running speeds, without wearing masks, wearing ordinary masks, and N95 masks. The results show that compared with running without a mask, the body's gas ventilation (can be understood as the amount of gas inhaled through the respiratory tract) and the body's oxygen uptake (the amount of gas actually used by the body) are significantly reduced, while the N95 mask Compared with ordinary masks, gas inhalation and intake will be reduced more. Therefore, when you wear a mask and run, the oxygen demand and supply will be seriously unbalanced. As the speed increases, the contradiction between oxygen supply and demand becomes more prominent, the heart rate also increases, and the skeletal muscles and heart muscles work hard. Exercise load gradually exceeds the body's tolerable range, and there is a risk of sudden death. Although the mask can protect against viruses, it increases the risk of sudden death during exercise.

For the student group, the Ministry of Education has made it clear that N95 masks cannot be used for physical exercise. In addition, whether it is a doctor, a school, or the media, it gives suggestions on how students take physical education classes, such as: under the premise of safety, encourage them to take off their masks for physical education classes; in a well-ventilated place, remember to take Exercise again under the mask; gradually resume physical exercise. Do not wear a mask during intense exercise, especially the N95 mask.

How to prevent sudden sports death

Sudden death from wearing masks is a special case of the new crown epidemic period, and students still need to prevent sudden death from exercising in daily physical exercise activities. To prevent sudden death from sports, we need to start from the following two aspects:

●Avoid risks associated with sudden sports death

To prevent sudden sports death, you first need to pay attention to and pay attention to some symptoms or signs related to sudden sports death in daily life and sports.

The following symptoms or signs need to be taken seriously:

1. Syncope or dizziness. Syncope is an important symptom that is prone to sudden sports death. If you find unexplained syncope, and dizziness or syncope that occurs immediately after exercise, you should pay attention to it and find out the cause.

2. Difficulty breathing during rest or light activity. Dyspnea mainly refers to abnormally uncomfortable breathing sensation, which is one of the main symptoms of heart and lung diseases.

3. Pain, especially chest pain. Discomfort in the chest, neck, jaws, arms, or other areas that may be caused by ischemia, especially exertional chest discomfort.

4. Palpitations or tachycardia. Mainly refers to the discomfort caused by the rapid, strong or irregular heart beat.

5. Family history. If there is an early sudden death of an individual younger than 50 years in the screened family, it indicates that the screened person is more likely to carry an inherited heart disease.

6. There are signs of cardiogenic disease. Main positive signs: slender limbs, spider fingers (toes), loose ligaments, tendons, hyperextension of the joints, lens dislocation, high myopia, cataract, retinal detachment, iris tremor, etc.

7. Known heart murmur.

8. Ankle edema.

9. Burning sensation or "cramp-like" sensation in the lower limbs when walking short distances.

●Reasonable control of exercise load

It is necessary to control exercise intensity during exercise, to match exercise load with one's own ability, and to improve the adaptability and psychological adjustment ability of the environment.

Use exercise heart rate, changes in breathing during exercise and self-feeling during exercise to monitor exercise intensity. When using heart rate to monitor exercise intensity, the greater the exercise intensity, the more obvious the body and heart respond to exercise stimuli, and the faster the heart rate. Generally, the percentage of maximum heart rate and the actual heart rate during exercise are used to monitor exercise intensity. In the physical education class on campus, the physical education teacher can control the intensity by counting pulses, and can use team heart rate products to monitor the intensity of physical exercise effectively if possible. In addition, students can monitor exercise intensity through breathing during exercise. During low-intensity exercise, breathing is easy and smooth, and you can sing. Only short sentences can be spoken during exercise, and a full sentence cannot be spoken. At this time, it is equivalent to moderate-intensity exercise and the breathing is relatively short. During high-intensity exercise, athletes will have difficulty breathing, unable to converse with people around them, and shortness of breath. Teachers can also ask students about their subjective physical strength during exercise to understand exercise intensity.
