What is the body composition?
In terms of physical fitness, the composition of the body is a term used to describe the percentage of fat in relation to bone and muscle. The composition of the body has a lot in common with the human appearance, because the muscle takes less space than fat. For example, two people who are the same height and weight can eventually look completely different, because one has more muscle than fat, and therefore is slimmer than the other. If a person is more athletic or muscular, the body fat percentage may be slightly lower, usually decreases between 7 and 19 percent in men and 10 and 25 percent for women.
There are several ways to measure the body composition. The most widespread method is a set of stirrups that measure the thickness of the fat under the skin. Commonly measured areas include ton belly, thighs and arms. These measurements are used to estimate how much the total body fat is present, but the caliper test can have a mistake of about 4 percent.
a much more accurate way of measuring bodyFat is an analysis of bioelectric impedance followed by air mites (ADP). During a later test, the person enters the airtight chamber and its body volume is measured by moving the air inside. The volume of the body and the weight is connected to determine the density and the percentage of body fat versus slim muscle mass is calculated.
It is also possible to achieve reading the body volume index using a dual energy of X -ray absorption (Dexa). Measurements given by this machine are usually accurate and include bone density, mineral content, fat tissue and lean tissue weight. Computer tomography (CT) and magnetic resonance imaging (MRI) Machines can also be accurate, so each is a good choice for doctors who monitor the percentage of the patient's body fat.
The composition of the body can be an important part of the overall health. To stay healthy and fit, people should generally try to keep the body volume index somewhere to the normal range for their sex. May not provide a complete picture of health, but cane it to be an important number.
