Adults in China: male 23 10, female 1800 is lower than this value, indicating that the respiratory function is weak.
Vital capacity refers to the amount of air that a person can exhale after inhaling deeply, which represents the maximum functional activity of the lungs in a time. Vital capacity is the maximum ventilation capacity of a breath, which reflects the potential ability of respiratory function in a certain sense.
Generally speaking, the better the body, the greater the vital capacity. In terms of age, adults have the largest lung capacity, while young people and the elderly are smaller.
People who do more exercise have greater lung capacity.
You can improve it through exercise ~
Those long-distance runners and swimmers have larger lung capacity ~
Improve vital capacity with correct breathing methods.
Oxygen can't be stored in the body, and people must always breathe fresh air. So breathing has a great influence on health. However, most people only use one-third of their vital capacity. According to the results of the national physical fitness monitoring in 2000 published by the State Sports General Administration and the Ministry of Education, the vital capacity of men aged 40-69 decreased from 3,347.2 ml to 24,465,438 0.3 ml, and that of women decreased from 2,362.3 ml to 65,438 0.7665,438 0.6 ml, which decreased by 28% and 26% respectively. The decline of vital capacity causes many diseases that affect the lung health of the elderly, such as tracheitis, asthma, pneumonia, pulmonary embolism, pulmonary fibrosis, lung tumor and so on. More importantly, once these lung diseases are combined with other diseases, the mortality rate is very high. Therefore, it is necessary to actively carry out breathing exercise, so that the lungs can be exercised, the vital capacity can be increased, and the vital capacity can be fully utilized, thus providing more oxygen for the blood and making it more energetic. The following are several healthy breathing methods, which you might as well do regularly to exercise and improve your vital capacity.
1. Take a deep breath. First, inhale slowly through the nostrils to fill the lower part of the lungs with air. When inhaling, the abdomen will bulge slowly because the chest is lifted up and the diaphragm is pressed down. Then continue to inhale and fill the upper part of the lungs with air. At this time, the ribs will be raised and the chest will become bigger. This process usually takes 5 seconds. Finally hold your breath for 5 seconds. After a period of practice, you can increase your breath holding time to 10 second, or even more. After the lungs suck enough oxygen, exhale slowly, and the ribs and chest gradually return to their original positions. Pause for a second or two, then start from the beginning and repeat 10 minutes. Long-term practice can become a normal breathing method.
2. Breathe quietly. Hold the right nostril with your right thumb, take a deep breath slowly through the left nostril, and consciously imagine that the air is flowing to your forehead. When the air in the lungs is saturated, press the left nostril with the index finger and middle finger of the right hand, hold your breath for 10 second, and then exhale. Then hold down the left nostril and start over. Do it five times per side.
3. Sleep and breathe. Doing this kind of breathing before going to bed is especially effective for insomnia. Lie on the bed with your hands flat at your sides, close your eyes and take a deep breath. Slowly raise your arms above your head, close to your ears, and touch the bed with your fingers. This process takes about 10 seconds, and both arms are restored at the same time. Repeat 10 times. This method can help you sleep peacefully.
4. Exercise and breathing. When walking or jogging, take the initiative to increase your breathing volume, breathe slowly and breathe quickly. When breathing slowly, the chest will gradually widen with inhalation and exhale faster. Exercise at least 20 times each time, several times a day.
