What is the relationship between lung capacity and health?

The increase of vital capacity is an important sign of lung development. 10 years old 1400 ml, adolescence 14- 15 years old/2000-2500 ml, boys 17- 18, girls/kloc. Adult male's vital capacity is about 3500ml, and female's is about 2500ml. Vital capacity is an important index of lung function. A large lung capacity means that your respiratory system is strong and can provide enough oxygen for your body, so your body is stronger, jumps higher and runs faster. Because it can provide enough oxygen for the brain and strengthen the ability of thinking activities. But this has nothing to do with "stimulating the brain and thinking fast". It can only increase the amount of thinking activities, but not speed up thinking activities. Vital capacity and height index: one of the comprehensive indexes of anthropometry. It is an important index of human respiratory function. Mainly through the ratio of human body's own vital capacity to height, that is, the relative value of vital capacity per 1cm height to reflect the correlation between vital capacity and height, and take this as a relative index to objectively and quantitatively compare and analyze individuals and groups of different ages and sexes. It has certain reference function for the selection of athletes in oxygen metabolism events and the comprehensive evaluation of students' physique. Its calculation formula is: vital capacity/height. Unit of measurement: milliliter (ml) stands for vital capacity, and centimeter (cm) stands for height. Vital capacity and body mass index: one of the comprehensive indexes of anthropometry. It is an important index of human respiratory function. Mainly through the ratio of human body's own vital capacity to body weight, that is, the relative value of vital capacity per 1kg body weight, to reflect the degree of correlation between vital capacity and body weight, so as to objectively and quantitatively compare and analyze individuals and groups of different ages and sexes. It has certain reference function for the selection of athletes in oxygen metabolism events and the comprehensive evaluation of students' physique. Its calculation formula is: vital capacity/weight. Unit of measurement: milliliter (ml) stands for vital capacity, and kilogram (kg) stands for weight.
