However, many people will have such an experience when running: after running for a certain distance, they begin to feel needle-like pain near their chest, back or ribs; Then the breathing rhythm is disordered, the pace is affected, and the running speed is slow. This is a fork.
Breathing during exercise is very common. If you run in cold autumn and winter, the possibility of breathing will increase. "Bifurcation refers to pain in a certain part of the chest and back during exercise. If you talk, breathe or cough, the pain may get worse. Medically called' respiratory muscle spasm'. " Professor of Sports Human Science said: Most of phlegm is due to insufficient preparation before large-scale exercise, and the human body suddenly enters a state of tension from a quiet state, so it is difficult to mobilize internal organs immediately, and oxygen and nutrients needed for muscle exercise cannot be supplied in a short time, so convulsions occur.
On the other hand, when running, the breathing frequency is too fast, but the depth is not enough, which is easy to make the breathing muscles contract continuously and quickly, and it will not be relaxed for a long time, leading to suffocation; In addition, cold weather or a lot of sweating make the sodium chloride content in the body too low, which can also lead to lateral wheezing. Therefore, in addition to preparing for activities and mastering the correct breathing methods, we should also pay special attention to avoiding breathing directly with our mouth when exercising in cold weather, sticking our tongue on the upper jaw, and letting cold air enter the respiratory tract through the gap in our mouth to avoid choking.
Experts point out: once you have bad breath, you don't have to stop exercising immediately. You can consciously adjust the breathing rhythm in time, slow down the breathing frequency and deepen the breathing range. After a period of persistence, most of the symptoms of bad breath will be relieved naturally and have no effect on the body; If the pain caused by barbecued pork gas is very serious, you can try to relieve it by holding your breath, stretching your muscles or slapping. The specific methods are as follows: take a deep breath, then hold your breath, hit the left and right chest with your fist from top to bottom, and then exhale slowly and deeply, or after inhaling deeply, ask others to hit the chest and back with their fists from top to bottom, and pay attention to moderation when slapping. In addition, lying on a mat and rolling your body repeatedly can also relieve it.
