BMI calculation

and weight, the BMI calculation offers a coefficient to be included in a "special evaluation grid that allows you to establish: normal weight, underweight, overweight and obesity (the latter, possibly classified in different levels of severity).

For further information: BMI and musculature) and the application limits it entails (it should not be used for the evaluation of children and elite athletes), today the simple BMI is partially replaced by more accurate and innovative estimation methods, but certainly less practical.

The normal range of the BMI (18.5-24.9 kg / m2) is wide precisely as a function of the subjective differences related to the physical structure of the population. As anticipated, the calculation of the BMI does not take into account muscle mass (greater , for example, in men and young people compared to women and the elderly), much less the differences regarding bone mass and the proportion between limb length and height.

To obtain greater accuracy it is however possible to integrate the BMI with the assessment of the constitution and morphological type - see below.

centimeters Weight Kg Sex Male Female YOUR BMI is kg / m2 and it's Your healthy weight according to the BMI is between: Kg And: Kg , skeleton and essential fat. It is well known that men have, on average, a higher musculature and bone structure than women, that the elderly are weaker than the young, and that women have a greater percentage of essential fat necessary for reproductive function. It is possible to integrate the calculation of the BMI with integrative equations that allow to estimate this variable as well.

This does not mean that there are women and elderly people with higher muscle volumes and lower fat mass than most men and young people. This is why the BMI assessment should not be used to estimate a subject's weight too precisely and accurately, but simply to identify the risk index associated with overweight and underweight.

of the non-dominant arm with a metric tape; the value is contextualized within a grid, differentiated between males and females, and identifying the condition of: normal, robust, slender.

Woman Constitution Man < 15 Slim < 17 15-16 Normal 17-18 > 16 Robust > 18

The morphological type, on the other hand, is calculated by dividing the stature (in centimeters) by the value of the constitution, and this result is also contextualized within a separate table between men and women. The operation allows to identify the condition of: normal, short-limbed, long-limbed.

Woman Morphological type Man < 9,9 Brevilineo < 9,6 9,9-10,9 Normolineo 9,6-10,4 > 10,9 Long-limbed > 10,4

By associating constitution and morphological type, comparing it to a "further evaluation grid, the desirable physiological BMI is obtained. This obviously does not apply to underweight and overweight, as they allow to identify the abnormal condition regardless of these two variables.
