It belongs to excessive exercise. After strenuous exercise, the heart muscle needs to send a lot of blood to the body, and the lungs need to absorb more oxygen to maintain physical fitness. It is suggested to reduce the amount of exercise or intermittent exercise to achieve the fitness effect more effectively and healthily.
Many people don't pay attention to the depth of breathing when running, so they will have shortness of breath after long-term exercise, which will lead to chest tightness and difficulty breathing. Although some people pay attention to deep inhalation, they often ignore the depth of exhalation. In fact, when running for a long time, only by appropriately increasing the depth of exhalation can we meet the body's demand for oxygen to the maximum extent. When the depth is enhanced, more waste gas can be discharged, and the negative pressure in the lungs can be increased, so that the inhalation is more labor-saving and the inhalation volume can be increased.
