The vital capacity index in National Students' Physical Health Standard refers to the amount of gas inhaled by individuals in the process of maximum inhalation after maximum exhalation. Vital capacity reflects the function and metabolic state of lung, and it is also one of the important indexes to judge the health status of the body.
Vital capacity reflects the health status of individual respiratory system. Normal lung capacity range should be related to personal height, weight, age, gender, physical exercise habits and other factors, and may also be affected by environmental factors. The causes of poor vital capacity often include chronic respiratory diseases, cardiovascular and cerebrovascular diseases, pulmonary apraxia, depression and so on.
By detecting the vital capacity index, the individual's physical health can be preliminarily evaluated. Because the vital capacity index is related to respiratory metabolism, organ tolerance and health status, the detection of vital capacity index can clearly reflect the metabolic status in the body and serve as a reference for physical exercise, rehabilitation and health prevention.
In practical application, vital capacity index is widely used to test the health status of athletes, bodybuilders and students. For school education, vital capacity index is particularly important.
Schools can help students improve their vital capacity index in an all-round way by organizing various outdoor sports activities that tend to develop humanized training mode, imparting safety and health knowledge, establishing a clean air environment, and broadening the ways of sports system, so as to better promote their own health.
It should be noted that vital capacity index is only one aspect of physical health, and should not be used as the only criterion to evaluate the whole physical health. Doctors and physical education teachers should comprehensively consider more inspection indicators and give individuals more complete evaluation and suggestions.
In a word, vital capacity index is one of the important indexes in the National Students' Physical Health Standard, which reflects the health degree, metabolic state and physical exercise of individual respiratory system and has great reference value. Schools and society should guide students to strengthen physical exercise, enhance physical fitness and cultivate healthy living habits, so as to comprehensively improve individual vital capacity index.
