Spirometry body mass index

The spirometry body mass index is one of the anthropometric composite indicators. The correlation between vital capacity and weight is mainly reflected by the ratio of human vital capacity to body weight, that is, the relative value of vital capacity per 1 kg of body weight. It is used for objective quantitative comparison analysis of individuals and groups of different ages and genders. It has a certain reference role in the selection of athletes and comprehensive evaluation of students' physical fitness related to the oxygen metabolism project. The calculation formula is: vital capacity / body weight. Units of measurement: milliliter (ml) for vital capacity and kilograms (kg) for weight.
