Determine the correspondence of height and weight

People with an ideal figure who are never concerned with the conformity of height and weight are rare, maybe only a few people for a hundred.

But there is little a priori of such a fate, all the rest have to constantly make efforts to ensure that if it does not approach the ideal, then at least bring your body back to normal.

A special problem for any person is always weight. This criterion must necessarily be combined with growth. And if a person, especially a small stature, suffers from excess weight, he looks extremely unpresentable, and he will have to try to ensure that the correspondence of height and weight is optimal.

Developed to determine the optimal ratio of height and weight of the table, but none of them can be considered absolute. Other factors should be taken into account, for example, skin thickness, length of legs, height of the torso, volume of the chest and so on. Without such an account, it turns out that two people with the same weight and height look different: one - slim, the other - full.

The most optimal ratio is considered the comparative index of musculoskeletal tissue and fat: for men - 9-15%, for women - from 12-20% fat from total weight.

There are different methods and tables that help determine how much the indicators deviate from the norm. The most popular method, in which the data on the correspondence of height and weight, as well as the body mass index, are taken as the basis, is the Quetelet index. But we must remember that for teenagers, the elderly, athletes, as well as pregnant and lactating mothers, these indices may be incorrect.

The Quetelet index indicates the formula for calculating the ideal weight: the body weight (in kilograms) divided by the growth rate (in meters, squared). The norm for men is the result - 19-25, the ratio of height and weight in women - 19-24. At an indicator less than 18.5 body weight is extremely low, which greatly increases the risk of diseases. Figures 25,0-29,9 indicate excess body weight, which can be defined as pre-fatigue, over-obesity: 30.0-34.9-I degree, more than 35.0-39.9-II degree, above 40, 0 - III degree, which is considered a threat to life.

However, the Quetelet index does not indicate how the fat is distributed over the body parts.

You need to resort to another formula: the waist measurement (the level of the navel) divided by the volume of the buttocks. At normal ratio in men should be the figure - 0,85, for women - 0,65-0,85. With an ideal physique, the waist girth should correspond to the "minus one hundred" formula and be 25 centimeters less than the hips, which should be about the same as the chest girth. A woman with a height of 172 cm should have a waist circumference - 72 cm, girth of hips and chest - about 97 cm.

The correspondence of height and weight changes with age. The older the person, the greater the indicator of normal weight.

But here it is also necessary to determine the norm by the formula, with the introduction of indices: P - growth and B - age (years). By definition of the most popular Brock formula, the body weight should be equal for people under 40 years old - P (ost) (centimeters) minus 110, over 40 - P (ost) (centimeters) minus 100.

When determining the norm of weight, it is necessary to determine the type of physique. People with asthenic (thin-skinned) type need to subtract 10% from the result obtained, and those with hypersthenic (broad-boned) body type should be added to the result of 10%.

To find out what kind of person a person is, you need to know that there are three categories: normosthenic (normal), hypersthenic (broad-chested) and asthenic (thin-boned) physique. The type of addition is simple: you need to measure (centimeter) the circumference of the thinnest place on the wrist: this is the indicator of the type (Solovyov's index). For men, according to this index, when the normostenic addition is ideal, the figure will be 18-20 cm, for women, respectively, 15-17 cm.

In hypersthenic type, these indicators will be, respectively, above 20 cm and 17 cm. In people with asthenic additions - less than 18 cm and 15 cm.

The ideal correspondence of height and weight can also be determined by the Nagler formula. According to this formula, 61 inches (152.4 centimeters) of growth should correspond to 45 kilograms of weight. Each taller inch (that is, every 2.45 centimeters) should correspond to 900 grams of weight. Plus another 10% of the result. With an increase of 176 centimeters, the base figure will exceed 23.6 centimeters, which should correspond to just over 21 kilograms, that is, the normal weight will be 66 kilograms. It is possible to add weight by about 10 percent (about 6 kilograms), so the total weight can be 72 kilograms.

The table of correspondence of height and weight can help to verify its parameters with normal indices.
