Determining the ideal weight is necessarycondition and in order to successfully start a diet, and for the proper calculation of the loads in training, and just as one of the most important indicators of self-control. Approximate method of determination according to Brock, when the constant 100 was taken away from a person's height in centimeters and received weight in kilograms, was recognized as obsolete, as not taking into account the type of the body structure of the test person.
В последнее время его заменил абсолютно другой the way to determine the indicators to strive for. Now everyone is interested in the question of how to calculate the body mass index (BMI). You can do the calculation of 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 body mass index in a few seconds. Mathematically, the calculated formula looks like the ratio of the weight of a person taken in kilograms to the square of height (in meters).
Next, the evaluation process comes down to comparingthe result obtained with tabular data. The filling in of the table took place on the basis of a variety of statistical research data. From this it follows that the results must be treated critically, as the ideal formula, taking into account all the unique features of the structure of your body, does not yet exist.
If we consider the concept of "normal massbody, it is calculated 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 body mass index is based on the classical analysis of classical indicators, weight and height of a person , but the main assessment occurs on tabular indicators.
When differences in human weight are given by typeconstitution, gender and age, this raises no questions. When an attempt is made to calculate the body mass index, which is optimal for a specific age, then there are certain differences and inaccuracies.
Again, the average process datastabilization of body weight in humans leads to a 25-year-old age. That is, the normal weight is calculated for a person of this age. In other words, weight in 25 years is the closest to normal, and even to the ideal.
A series of parallel studies this theory makesuntenable. The mass of the human body - the value is not quite constant. With age, an increase of up to 8% is observed. But in old age, to calculate the body mass index, it is necessary to take into account the reduction of its indicators.
If during the conduct of such introspectionyou are not satisfied with the results, then of course you need to look for the cause in yourself. But sometimes the feature of the structure of an individual goes beyond the usual indicators. Calculate the body mass index in this case is necessary by the general rules, but the table for the evaluation should be selected according to the group to which you are the closest.
For example, narrow-chested asthenics are relatively easier.normostenic, and the normal weight of hypersthenic (wide-breasted) exceeds the value for the representatives of the first two groups. But this difference was made taking into account the volume of the chest.
Но ведь есть и уникальные «экземпляры», которые according to the features of the structure of their bodies do not fit into one of the frames and calculated tables. For particularly accurate calculations, these values of the subcutaneous fat layer are used.
For average estimates, below are given the data of body mass index in a normal form, as well as beyond the norms.
If in your calculations you got an index less18.5 kg / m2, this is a clear sign of body mass deficiency. If the MT index is in the range of 18.5 - 24.9, then your weight is closest to the ideal. Owners of the index MT 25 - 29.9 are overweight. The first degree obesity is characterized by a BMI of 30 to 34.9. The second degree of obesity among owners of the index in the range of 35 - 39.9. An indicator of BMI over 40 corresponds to the III degree of obesity.
