Calculate body mass index. One of the conditions for true self-control

Determining the ideal weight is a prerequisite for both successfully starting a diet, and for correctly calculating loads in training, and simply as one of the most important indicators of self-control. The approximate method of determining Brok, when a constant of 100 from a person's height in centimeters was taken and weight was received in kilograms, is considered obsolete, as it does not take into account the type of body structure of the subject.

Recently, it was replaced by a completely different way of determining the indicators to which one should strive. Now everyone is interested in the question of how to calculate the body mass index (BMI). You can calculate this coefficient manually, you can download a special program, or you can use a certain web service. The abundance of various online calculators in the network allows you to calculate the body mass index in a few seconds. The mathematically calculated formula looks like the ratio of the weight of a person taken in kilograms to a square of growth (in meters).

Further, the evaluation process is reduced to comparing the result with tabular data. The table was populated based on a variety of statistical research data. From this it follows that the results must be treated critically, since there is no ideal formula that takes into account all the unique features of the structure of your body.

If we consider the concept of "normal body mass", then its calculation is made for a group of people of the same sex, age, height and other indicators. Each new condition leads to a more accurate definition of indicators for a particular person. The ability to calculate the body mass index is provided on the basis of a classic analysis of classical indicators, weight and height of a person, but the main evaluation is based on tabulated indicators.

When the differences in the weight of a person are set by the type of constitution, gender and age, this does not raise questions. When an attempt is made to calculate the body mass index, which is optimal for a particular age, then there are certain disagreements and inaccuracies.

Again, the average statistical data on the process of stabilization of body weight in humans lead to a 25-year-old age. That is, the normal weight is calculated for a person of this age. In other words, the weight at 25 years is the closest to the normal, and even to the ideal.

A number of parallel studies make this theory untenable. The mass of the human body is quite a constant. With age, it increases to 8%. But to old age, in order to calculate the body mass index, it is necessary to take into account the decrease in its indexes.

If in the course of this self-analysis the results did not satisfy you, then of course you need to look for the cause in yourself. But sometimes the peculiarity of the structure of an individual goes beyond the usual indicators. Calculate the body mass index in this case is necessary by general rules, but the table for evaluation should be selected according to the group that you most closely belong to.

For example, narrow-chested asthenics are relatively lighter than normostenics, and the normal weight of hypersthenic (broad-chested) exceeds the values for representatives of the first two groups in terms of magnitude. But this difference was made with regard to the volume of the chest.

But after all, there are unique "specimens" that, according to the peculiarities of their body structure, do not fit into any frames and calculated tables. For particularly accurate calculations, the values of the subcutaneous fat layer are used.

For the average estimates, the body mass index data in the normal form are given below, as well as those that go beyond the norms.

If in your calculations you received an index of less than 18.5 kg / m2, then this is a clear sign of a deficit in body weight. If the MT index is between 18.5 and 24.9, then your weight is closest to the ideal. Holders of the index MT 25 - 29.9 have an overweight body. For obesity, the first degree is characterized by a BMI of 30 to 34.9. The second degree of obesity among index holders is in the range of 35 - 39.9. The BMI score of more than 40 corresponds to the third degree of obesity.
