What is the analysis of the body composition?

The body composition analysis is a physical test that measures the proportion of different components of human body. The human body consists of water, proteins, fat and minerals - but for most purposes it is a level of fat compared to a slender mass that is interesting. Generally, most tests of the body composition measure measure the ratio of fat to lean tissue. Body fat or fat tissue has chemical and physical properties that allow a number of analytical methods each having its own advantages and restrictions. The most common forms of body composition analysis are the body weight index (BMI,) the testing of the skin of the skin, bioelectric impedance and hydrostatic weighing. BMI is used by fitness centers, doctors and insurance companies attempt to provide a picture of body composition by mathematical comparison of height with one of the following form:

• bmi = weight in pounds * 703 / height in inches 2

• bmi = weight in kg / height 2
  meters.

by using these formulasHe considers BMI measurements between 19 and 21, with a higher number of overweight and a lower number of underweight. The obvious limitation of BMI as a measurement is that it cannot take into account the composition of the body, and therefore is usually considered to be a good estimate for the normal population, but may be inaccurate for those who have a very athletic set.

Skin testing is used to analyze the body composition for years and is generally considered to be a precise scale of body fat. The test is based on the assumption that about half of the body fat is immediately under the skin. The measurements are carried out at strategic locations, including biceps, triceps, middle and lower back and calf, and the results are then applied to an equation used to estimate the total percentage of body fat. While the Skin Fold test is accurate, it requires a certain degree of expertise and accuracy by a person performing measurements. Moreover, for many people, the EMOC measurement process can beInonally unpleasant, in which case less invasive methods could be more advantageous.

Bioelectric impedance is based on the principle that lean tissue is electrically more conductive than fat. A slight, painless electric current passes through the body, usually from the wrist to the leg. This test is often the method of analyzing the body composition in clubs, because the test can be performed fully dressed and requires minimal skills from the examiner. The device needed for testing bioelectric impedance can be expensive compared to the calipers, so this testing can be found mainly in large devices.

Hydraostatic weighing is often referred to as a gold standard for analysis of the body composition. Hydrostatic weighing is generally considered to be the most accurate means of determining the composition of the body, it is based on the idea that fat is less dense than water. The process compares human body weight on dry soil with their underweight weight and uses the results to calculate the proportion of fat to lean tissue. Although accurate,Hydrostatic weighing is usually performed only in the laboratory environment because it requires equipment and skills that would be impractical to replicate in family medicine or fitness settings.

Regardless of which method is used, normal body fat measurement is generally considered 18-30% in women and 15-25% in men. If fat levels fall slightly lower, there is a reduced ability of pillows and storing certain vitamins and an increased risk of osteoporosis. Any higher and there is a risk of cardiovascular disease. Where a person falls optimally in Normalurozhah depends on many variables, including genetics, level of activity and life phase.
