The National Standard for Students' Physical Fitness and Health stipulates the corresponding evaluation indexes from primary school to university, and evaluates them according to the test values of various items in the National Standard for Students' Physical Fitness and Health. Except that the body mass index is calculated according to the measured height and weight, other items are scored directly by looking up the table with the test values.
According to the students' total academic year scores, the scores are: above 90.0 for excellent, 80.0 ~ 89.9 for good, 60.0 ~ 79.9 for passing, and below 59.9 for failing.

Methods to improve vital capacity:
First, deep breathing method: first inhale slowly through the nostrils to fill the lower part of the lungs with air. When inhaling, the abdomen will bulge slowly because the chest is lifted up and the diaphragm is pressed down. Then continue to inhale and fill the upper part of the lungs with air. At this time, the ribs will be lifted up and the chest will expand. This process usually takes 5 seconds. Finally hold your breath for 5 seconds.
Second, physical exercise method: physical exercise can increase lung capacity, and you can swim in the water, so that water will increase resistance training, and the body will accelerate the promotion of oxygen flowing into the blood and keep breathing, which will have a good exercise for lung function and improve lung capacity.
