body composition


Also found in: Wikipedia.

body composition

the relative proportions of protein, fat, water, and mineral components in the body. It varies among individuals as a result of differences in body density and degree of obesity.

body composition

A physical fitness term for the percentage of fat, bone and muscle in the body, of which fat is of greatest interest. Healthy adults males have 6% to 24% fat; healthy adult females have between 14% and 31% fat.

bod·y com·po·si·tion

(bod'ē kom-pŏ-zish'ŭn)
An estimate of the proportions of major components of a living body, as water, nitrogen, sodium; more specifically, the proportion of lean body mass to fat.

body composition

whole-body composition is of interest in the contexts of control of body weight, assessment of obesity, and sport and exercise,. It comprises total body fat (essential fat plus storage fat) and fat-free body mass (FFM) (includes muscle, water and bone). From body density measurements, using established corrections and equations, the ratio of fat mass to fat-free mass can be calculated, based on the much lower density of the fat compartment. However, within the FFM, bone is more dense than muscle, so if there is either relative loss of bone density (osteoporosis) or increase in muscle mass (with training), fat percentage may be overestimated. densitometry techniques include underwater (hydrostatic) weighing and air displacement plethysmography. Estimates can be made of lean body mass (LBM), body mass devoid of storage fat, but LBM does not exclude essential fat, so it is slightly higher than the FFM. See also body fat, body fluids.
