One can trace to Archimedes the idea that in a system consisting of two additive components which are mixed but the densities of which are known ( d l , d 2 ) , the determination of the density of the system ( D ) allows one to calculate the proportional masses of the two components. Let’s denote these components as W1 and W2.S Then, in a system with total weight W = W1 + Wz, the general equation for calculating component W1 expressed as a fraction (w1) of the total body weight is: 

The Measurement of Body Composition : Techniques and Implications

Composition: Techniques and Implications 1 A.V. Kurpad Even with high levels of precision in each of the primary measurements, it is unlikely that a precision of greater than 0.5 kg fat mass would be

Estimation of body composition by whole body volumetry in human subjects.

Body density measurements have been used since 1757 for studying body composition in human subjects and a series of equations for the estimation of percent body fat in Western subjects may however not be applicable to Indian populations.

Body Composition in Adolescence

Body composition data can help in estimating certain nutritional requirements for growth and the metabolic balance method is not equal to this task, and one can look forward to more realistic estimates based on these newer techniques.

The present attempt at a synthesis of the basic methodological aspects begins with the anatomist's handiwork and goes on to somatometric models and to procedures based on determinations of body density and body water.

Comparison of body composition methods in obese individuals.

Body composition measurements in obese individuals derived by the Keys/Brozek equation and the Siri equation are compared with two other techniques (total body water, and the 3-compartment model combining total body water with body density) involving different assumptions.

Of the methods at present available for estimating the proportion of body fat in living individuals, hydrostatic weighing is the most reliable.

STUDIES ON BODY COMPOSITION II. THEORETICAL CONSIDERATIONS REGARDING THE MAJOR BODY TISSUE COMPONENTS, WITH SUGGESTIONS FOR APPLICATION TO MAN

The mammalian body can be regarded as consisting of certain major phases: fat, bone, muscle, skin, nervous and visceral tissue, and to measure the relative proportion in the intact animal requires an indirect method.

THE SPECIFIC GRAVITY OF HEALTHY MEN: BODY WEIGHT ÷ VOLUME AS AN INDEX OF OBESITY

The data support the concept that the comparatively low specific gravity of fat makes the measurement of the specificgravity of the body mass valid for the estimation of fat content.

Density, fat, water and solids in freshly isolated tissues.

The biological extremes in a water:fat:protein system thus operate in such a way that the quantity of fat can be predicted from an equation containing three variables, i.e. the initial weight and density of a tissue and its quantity of water.

Fat, water and tissue solids of the whole body less its bone mineral.

Except for bone mineral, the body is shown to belong to the same water:fat:protein system as its soft tissues as well as its hard tissues.
