People with a perfect figure, who never cares about matching height and weight, are rare, maybe just a few people per hundred.
But such spoils of fate are a priori small, all the rest have to constantly make efforts so that if they do not get closer to the ideal, then at least bring their body back to normal.
A special problem for any person is always weight. This criterion must be combined with growth. And if a person, especially of 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.
Designed to determine the optimal ratio of height and weight of the table, but none of them can be considered absolute. Other factors must be taken into account, for example, skin thickness, leg length, torso height, chest volume, 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 indicators of musculoskeletal tissue and fat: for men - 9-15%, for women - from 12-20% of fat of the total weight.
There are various methods and tables that help determine how the indicators deviate from the norm. The most popular technique, in which the data on the correspondence of height and weight, as well as the body mass index, are taken, is considered the Ketle index. But we must remember that for adolescents, the elderly, athletes, as well as pregnant and lactating mothers, these indices may be incorrect.
The Ketle index indicates to calculate the ideal weight, use the formula: body weight (in kilograms) divided by the growth indicator (in meters squared). The norm indicator for men is the result - 19-25, the ratio of height and weight in women - 19-24. With an indicator of less than 18.5, body weight is extremely low, which greatly increases the risk of disease. The numbers 25.0-29.9 indicate excess body weight, which can be defined as obesity, 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 Ketle index does not indicate how fat is distributed over parts of the body.
It is necessary to resort to one more formula: the indicator of the waist volume (navel level) is divided by the indicator of the volume of the buttocks. In a normal ratio, men should have a figure of 0.85, and women, 0.65-0.85. With an ideal physique, the waist circumference should correspond to the “height minus one hundred” formula and be 25 centimeters smaller than the hip circumference, which should be about the same as the chest circumference. A woman with a height of 172 cm should have a waist circumference of 72 cm, a circumference of the hips and chest - about 97 cm.
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 the indices: P - growth and B - age (years). According to the definition of Brock's most popular formula, body weight should be equal for people under 40 years old - P (ost) (centimeters) minus 110, older than 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-boned) type need to subtract 10% from the result, and those with a hypersthenic (broad-boned) body type should add 10% to the result.
To find out what type a person belongs to, you need to know that there are three categories: normosthenic (normal), hypersthenic (broad-bones) and asthenic (thin-bones) physique. The type of addition is established simply: you need to measure (with a centimeter) the circumference of the thinnest place on the wrist: this is the indicator of the type (Soloviev’s index). For men, according to this index, with normosthenic addition, the figure of 18-20 cm will be ideal, for women, respectively, 15-17 cm.
With the hypersthenic type, these indicators will be, respectively, higher than 20 cm and 17 cm. In people with asthenic constitution, they are less than 18 cm and 15 cm.
The perfect match between height and weight can also be determined by the Nagler formula. According to this formula, 61 inches (152.4 centimeters) in height should correspond to 45 kilograms of weight. For every inch greater than height (that is, every 2.45 centimeters), 900 grams of weight should correspond. Plus another 10% of the result. With an increase of 176 centimeters, the excess of the base figure will be 23.6 centimeters, which should correspond to a little more than 21 kilograms, that is, the normal weight will be 66 kilograms. Weight gain of about 10 percent (about 6 kilograms) is allowed, so that the total weight can be 72 kilograms.
A table of correspondence between height and weight can help verify your parameters with normal indicators.
