Insisting on sports meeting has a profound experience, that is, breathing evenly Some elderly friends will be short of breath when they are in a hurry, indicating insufficient lung function.
When people are anxious and angry, they will feel that their blood oxygen is insufficient and they will be short of breath. Instinctively, they will supplement the insufficient oxygen in the blood by increasing the breathing frequency, so shortness of breath indicates the deficiency of lung function. Another common problem of the elderly is shallow breathing, which is due to the decline of kidney-qi function and also represents the deficiency of lung function.
Moderate exercise can improve the respiratory function of the lungs and improve the blood circulation and self-supply of the lungs. For example, running, some friends have to stop because they can't breathe, which shows that their physical foundation is poor and their lung function is seriously insufficient.
However, with the persistence of exercise, the oxygen consumption of various tissues of the body, especially muscle tissues, increases, and the oxygen provided by human breathing will become more and more sufficient, and the state of shortness of breath and breathlessness will gradually improve. Therefore, the exercise should be gradual, not too hard. Persisting in exercise will improve the inspiratory function of the lungs.
