Lung capacity range for primary and secondary school students, comparison table of lung capacity sta

Lung capacity refers to the maximum inhalation followed by the maximum exhalation, and the amount of air that can be exhaled is called lung capacity. Primary and secondary school students about 2000 2500, the current primary and secondary school students generally decline in physical fitness, the Ministry of Education released data in 2004: 7 12-year-old primary school boys and girls lung capacity decreased by 38 ml, 44 ml, so attention should be paid to primary and secondary school students physical exercise.

More than 3000.

Some are calculated based on body weight.

I'm the highest.

The electronic one is 5527

The mechanical one is 6700

Awesome, right?

The normal lung capacity of a man is 3500-4000 ml, and the normal lung capacity of a woman is 2500-3500 ml.

Inhale once and then exhale as much as you can. Vital capacity is the maximum ventilation volume for one breath, which in a certain sense can reflect the potential capacity of respiratory function. The lung capacity of an adult male is about 3500 ml and that of a woman is about 2500 ml.

Lung capacity is greatest in the prime of life, and smaller in young and older people. The better the health of the person, the greater the lung capacity, and the lung tissue damage such as tuberculosis, pulmonary fibrosis, atelectasis, or lobectomy to a certain extent may reduce the lung capacity; Kyphosis, pleural thickening, exudative pleurisy, or pneumothorax can also limit lung expansion and reduce lung capacity. Thus, a marked decrease in vital capacity is a sign of restrictive ventilation disorder.

Because the measurement method of spirometry is simple and reproducible, it is a commonly used indicator for health examinations. Because the measurement of spirometry does not limit the speed of expiration, it cannot detect diseases with poor airway ventilation, so the use of temporal spirometry is ideal as a dynamic indicator of lung function. Temporal vital capacity is the maximum inhalation followed by the exhalation at the fastest speed until the exhalation is finished.

At the same time, the volume of exhaled air at the end of the second is recorded separately. A normal person should exhale % and 99% of their lung capacity, respectively. People with pulmonary obstructive pulmonary disease often take 5 to 6 seconds or more to exhale their full lung capacity; In many pathological conditions where respiratory movement is restricted, vital capacity increases in the first second, and full vital capacity can be exhaled in advance.

Therefore, temporal vital capacity can be used as a reference to distinguish obstructive or restrictive ventilation disorders.

Generally now, a normal primary school student should be between 1500 and 2000.

The normal range of lung capacity for male and female primary school students is 700ml-3200ml and 600ml-2500ml, respectively. Enlarges with age.

1. Normal range of lung capacity for primary school men: 700ml-1700ml for the first grade; 2nd grade 800ml-2000ml; 3rd grade 900ml-23000ml; 4th grade: 1100ml-2600ml; 1300ml-2900ml for 5th grade and 1500ml-3200ml for 6th grade.

2. Normal range of lung capacity for primary school women: 600ml-1400ml for the first grade; 2nd grade 700ml-1600ml; 3rd grade 800ml-1800ml; 4th grade: 900ml-2000ml; 1050ml-2250ml for 5th grade and 1200ml-2500ml for 6th grade.

According to the National Student Physical Health Standards, the passing standard for lung capacity of primary school students is divided into grades 1 to 6 according to gender, and the passing standard is: (male and female) in milliliters.

Year 1 . Year 2 .

Year 3 . Four brigades are erected grades.

Fifth grade: 1300, 1050 for the largest number of splits.

6th grade: 1500 ml, 1200 per pen.

To test your spirometry, you need to pay attention to:

1. Do not exhale too hard during the test to prevent air leakage.

2. Do not inhale twice during the test. The orifice of the spirometer used should be strictly disinfected.

3. When performing the maximum inhalation and exhalation, you can be free from the body posture, such as bending the abdomen when exhaling. Pay attention to the time interval when repeating the measurement.

4. The inhalation method can be chest and abdomen synchronization, that is, exhale slowly and deeply, try to exhale out, nose to prevent air leakage, chest up and head up, exhale can be properly bent, this posture test results will be better.

The average lung capacity of adults of all ages is about 3500-4000ml for men, 2500-3500ml for women, and 5000ml for regular sports.

Lung capacity decreases with age, and generally the older you get, the lower your lung capacity. Having a large lung capacity is more suitable for exercise, and it is also suitable for cardiovascular and cerebrovascular oxygen supply, and you often feel refreshed and refreshed. Which methods can improve lung capacity, such as running, swimming, etc., can be very good to improve lung capacity.

What does lung capacity represent

Lung capacity body mass index is the ratio of the body's own lung capacity to body weight, that is, the relative value of lung capacity per kilogram of body weight to reflect the correlation between lung capacity and body weight, which is mainly used for objective quantitative comparison and analysis of different ages and genders, and individuals and the masses. In the selection of athletes in aerobic metabolism events and the comprehensive judgment of students' physique.

It has a certain reference role, so in real life, lung capacity, according to different ages, different genders, its numerical standards are different. Under normal circumstances, lung capacity is the maximum ventilation volume for one breath, which can reflect the potential capacity of respiratory function in a certain sense.

The lung capacity of adult men is about 3500 ml, adult women are about 2500 ml, and the lung capacity of adults is the largest, and the lung capacity of young and elderly people is relatively small.

Spirometry standards for each age group are as follows:The vital body mass index is 46. The evaluation criteria for spirometry body mass index are:

Excellent: 75ml kg or more for men, 74 70ml kg for women; Good: 69 64ml kg for males, 63 57ml kg for females; Pass:

56 54ml kg for males, 53 44ml kg for females; Fail: 43ml kg or less.

To judge a person's lung capacity, there is a standard for lung capacity body mass index, that is, the relative value of lung capacity per 1kg of body weight to reflect the correlation between lung capacity and body weight, which is used to conduct objective quantitative comparative analysis of individuals and groups of different ages and genders.

It has a certain reference role in the selection of athletes and the comprehensive evaluation of students' physical fitness in oxygen metabolism projects. It is calculated as follows: spirometry and body weight. Units of measurement: milliliters (ml) for lung capacity, kilograms (kg) for body weight.

Lung capacity varies by sex and age, with males significantly higher than females. Before the age of 20, the lung capacity gradually increases with age, and the increase is not obvious after the age of 20. The lung capacity is about 3,500,4,000 milliliters for adult men and 2,500,3,000 milliliters for adult women.

Lung capacity depends primarily on how relaxed the chest wall expands and contracts.

Lung capacity declines with age, by 9% to 27% every 10 years, but people who have been physically active for a long time can still maintain normal lung capacity.

Once the body needs a large amount of oxygen consumption (such as long-term study, work, strenuous exercise), there will be a serious shortage of oxygen, resulting in headaches, dizziness, chest tightness, malaise, poor concentration, memory loss, insomnia and other adverse reactions, which will not only affect study and work, but also cause many irreparable losses to physical health.

1. Average reference value of lung capacity of primary school students.

Boys in grades 1 to 6.

1342ml for 7 years old, 1496ml for 8 years old, 1972ml for 9 years old, 1843ml for 10 years old, 2010ml for 11 years old, 2200ml for 12 years old.

Girls in grades 1 to 6.

1213ml for 7 years old, 1354ml for 8 years old, 1516ml for 9 years old, 1685ml for 10 years old, 1883ml for 11 years old, 2077ml for 12 years old.

2. What is the impact of low lung capacity in primary school students?

In general, people with better health have greater lung capacity. As we age, our respiratory muscles develop and our lung capacity increases. The growth of male lung capacity has accelerated since the age of 12 and 13, and tends to be stable at the age of 19 and 20, about 3500 4500 ml, and the growth of female lung capacity is relatively stable, gradually slowing down after the age of 15, and tends to be stable at the age of 18 and 19, about 2500 3500 ml.

The harm of adolescents' lung capacity decline not only affects their current physical development, but more importantly, they are more susceptible to major diseases in the future.

In the process of physical testing, lung capacity has also become an indispensable test item, because through the lung capacity test, it can detect whether the lungs are in a normal state and whether there are respiratory diseases. However, for people of different ages, there will be differences in the corresponding indicators of lung capacity.
