What is the normal lung capacity? What is the relationship between the size of vital capacity and what?

First of all, the vital capacity of normal adult males is about 3500-4000 ml, and that of adult females is about 2500-3000 ml. The size of vital capacity is related to the way of breathing. Learn to breathe through your nose. Breathing through the mouth will hinder the filtration and regulation of air before it enters the lungs and increase the burden on the lungs. Lack of exercise. Long-term lack of exercise is the main reason for the low vital capacity of mentally active people. If you can't breathe after climbing three floors, you need to exercise more and increase your vital capacity. Low vital capacity also means that the body's ability to absorb oxygen and expel carbon dioxide is weak.

Secondly, it is related to smoking. Pay attention to air hygiene. Always open the windows of the room to promote air circulation. Cigarettes contain many substances that are very harmful to the lungs. Smokers must give up smoking. Exercise vital capacity, combined with the right method, will make you have enough breathing. Good breathing is related to the extent to which breathing is pushed and the closure of vocal cords to block breathing. In other words, your vocal cords can't close naturally, and no amount of air can escape.

Furthermore, the size of vital capacity is related to running. First of all, it must be emphasized that the level of vital capacity does not directly determine your running ability, but to some extent determines your talent limit. Vital capacity refers to the total amount of gas that can be exhaled after one inhalation, which can indirectly reflect the human body's ability to absorb oxygen and eliminate waste gas. For normal adults, if the vital capacity is lower than the normal level, dizziness, tinnitus and inability to concentrate due to insufficient oxygen intake will occur. In the process of exercise, especially in the case of aerobic exercise that requires a lot of oxygen consumption, the human body is more prone to dizziness and limb weakness.

In addition, we should know that many people have measured their vital capacity during physical examination. The size of vital capacity can reflect our physical condition to some extent, and can also predict our life span. Because the size of vital capacity is related to human metabolism, and metabolism is mainly related to detoxification, the greater the vital capacity, the longer our life may be.
