Take a deep breath. How big can you blow the balloon? This small method can compare people’s lung capacity and simply detect your health status. People with large lung capacity not only have good cardiovascular function, strong muscle activity ability, loud voice, and even sing better.
large lung capacity, strong ability to supply oxygen
“Vital capacity refers to the total amount of gas exhaled after one effort to inhale. It is the maximum ventilatory capacity of one breath. In a certain sense, it can reflect the potential capacity of ventilator energy.” Wang Xiangdong, associate researcher of the Scientific Research Institute of the State Administration of sports, said that lung capacity can show a person’s cardiopulmonary function. People with large lung capacity have stronger oxygen supply capacity.
The lung is a transit station for gas exchange. Sun Weixing, an associate professor of Beijing Sport University, told this reporter that the body needs oxygen to operate every moment. Only when the oxygen supply is sufficient can all organs work normally; At the same time, the carbon dioxide produced by the body’s metabolism must also be discharged from the body through the lungs. Therefore, the lung capacity is large, and the ability to inhale oxygen and exhaust gas is stronger. During long-term study and sports, the human body needs to consume a large amount of oxygen. At this time, people with large lung capacity rarely have inattention, dizziness, chest tightness and other phenomena.
In anoxic conditions such as high altitude, people with high lung capacity can let more fresh air reach the alveoli, so as to get enough oxygen in the hypoxic environment; People with strong lung function have strong ability to exhale and exhale, and the ability to control sound is also stronger. “It can be said that strong lung function can make people’s brain more flexible and their body healthier.”
at the age of 35, lung capacity began to decline.
Lung capacity varies with gender and age, and is significantly higher in men than in women. Vital capacity is also closely related to height, weight and chest circumference. Generally speaking, the difference in lung capacity of people with similar age, height and weight within the normal range will not be too large. “If you take a deep breath and blow the same elastic balloon, the person with the larger balloon will have a better lung capacity.”
In the national physique measurement standard, the size of vital capacity is generally measured by using a spirometer. In daily life, people can use the method of climbing stairs to test. Sun Weixing said, for example, that at the age of 25, the human body’s cardiopulmonary function reached its best. At this time, if you climb four flights of stairs continuously, your breathing will be natural, but you will feel a little shortness of breath, which means that your lung capacity is basically normal; If you feel difficult to breathe and have severe wheezing, your vital capacity may be lower than the normal standard, and you need to strengthen exercise. Older people can slow down and lower the floor during detection.
“Decreased lung capacity will accelerate human aging.” Sun Weixing said, “generally, after the age of 35, the lung capacity starts to decline gradually with the growth of age. At this time, the oxygen supply of the human body is 5% – 10% less than that of young people, and the aging of organs will also accelerate. But if you can persist in physical exercise, you can obviously improve the cardiopulmonary function and slow down the aging of the human body.” many long-distance runners and swimmers in their 40s and 50s have lung capacity equivalent to that of young people in their 20s, and their physiological age is also relatively younger. “
