The netizen asked the standard of vital capacity for the first grade? Lung capacity is related to people's physique, sex and age.
The standard of vital capacity of primary school students is: male: the vital capacity is about1300-1500m; Girl: The vital capacity is about 1200- 1400ml. With the growth of age and physique, lung capacity will also increase, generally around the age of 20, lung capacity will reach a stable state. If the child's lung capacity is relatively low, it is necessary to strengthen physical exercise and do more sports to increase his lung capacity, such as long-distance running, swimming, playing football and basketball.

Refer to the standard of National Students' Physical Health Standard. Grade four 1 100 to 1820 is qualified, 1900 to 2 150 is good, and 2400 to 2600 is excellent. Grade 900 to 1620 is a pass, grade 1700 to 1900 is good, and grade 2 100 to 2300 is excellent.
In order to establish and improve the national monitoring and evaluation mechanism of students' physical health, and encourage students to take an active part in physical exercise, the Ministry of Education issued the National Standard for Students' Physical Health (Revised 20 14), which requires all schools to carry out compliance tests covering all grades of the whole school every academic year, and grade them according to the total scores of students in the academic year. Only students with good or above grades can participate in the awards. 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.
