What is the standard of vital capacity for middle school students?

Many middle school students have insufficient lung capacity due to lack of exercise, which seriously threatens their physical safety and health. So what is the standard for lung capacity of middle school students? Let me introduce it to you below.

The growth of lung capacity is an important indicator of lung development. At the age of 10, the lung capacity is 1400 ml. By the age of 14-15 during puberty, the lung capacity can increase to 2000-2500 ml. Boys can approach or reach the lung capacity of adults when they are 17-18 years old, and girls can reach the lung capacity of adults when they are 16-17 years old.

The lung capacity of an adult male is about 3500 ml, and that of an adult female is about 2500 ml.

Lung capacity is an important indicator of lung function. A large lung capacity means that your respiratory system is strong and can provide the body with enough oxygen, so your body will be stronger, jump higher, and run faster; and because it can provide enough oxygen to the brain, it also enhances your thinking ability. But this is different from

It doesn’t matter if you “stimulate your brain and think faster”, it can only increase the amount of thinking activity without speeding it up.

Vital capacity height index:

One of the composite indicators of anthropometric measurement. It is an important index of human respiratory function. The correlation between lung capacity and height is mainly reflected by the ratio of a person's lung capacity to height, that is, the relative value of lung capacity per 1 cm of height. It is used as a relative indicator to conduct objective quantitative comparative analysis of individuals and groups of different ages and genders. It plays a certain reference role in the selection of athletes for oxygen metabolism events and the comprehensive evaluation of students' physical fitness. The calculation formula is: vital capacity/height. Unit of measurement: Vital capacity is measured in milliliters (ml) and height is measured in centimeters (cm).

Vital capacity to weight index:

One of the composite indicators of anthropometric measurement. It is an important index of human respiratory function. The correlation between lung capacity and body weight is mainly reflected by the ratio of a person's lung capacity to body weight, that is, the relative value of lung capacity per 1 kg of body weight. It is used to conduct objective quantitative comparative analysis of individuals and groups of different ages and genders. It plays a certain reference role in the selection of athletes for oxygen metabolism events and the comprehensive evaluation of students' physical fitness. The calculation formula is: vital capacity/body weight. Unit of measurement: Vital capacity is measured in milliliters (ml) and body weight is measured in kilograms (kg).

The above is my opinion on this issue. If the patient has the above problems, it is necessary to pay attention to take appropriate treatment methods in time. This can well ensure the safety of middle school students and avoid dangerous situations for middle school students due to the above problems. Finally, I wish the middle school students good health.
