The equation (the squared value of height divided by impedance measurements of the right half of the body) showed a correlation coefficient of 0.92 with total body water. This equation, Hoffer proved, is known as the impedance index used in BIA. [16] In 1983, Nyober validated the use of whole body electrical impedance to assess body composition ...
The body fat percentage is a measure of fitness level, since it is the only body measurement which directly calculates a person's relative body composition without regard to height or weight. The widely used body mass index (BMI) provides a measure that allows the comparison of the adiposity of individuals of different heights and weights.
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
The widely used body mass index (BMI) provides a measure that allows for the comparison of individuals of different heights in terms of their weight. Due to differences in body composition, the BMI is not necessarily an accurate indicator of body fat; for example, individuals with greater muscle mass will have higher BMIs.
Besides that, the performance of movement is why one studies the body size, proportionality, body composition, and human shape. It is confusing to write at the same level the performance of movement because then one never clearly portrays the purpose of the discipline, meaning that a descriptive knowledge of the body is the sole purpose while ...
