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 beExpand
Estimation of body composition by whole body volumetry in human subjects.
TLDR
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. Expand
Body composition measurement: a review of hydrodensitometry, anthropometry, and impedance methods.
TLDR
Two of the main methods of estimating body composition in this review have been in use for decades, but the third method (bioelectrical impedance) is more recent. Expand
Body Composition in Adolescence
TLDR
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. Expand
Body composition: models and estimation equations.

  • American journal of physical anthropology
  • 1966
TLDR
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. Expand
Comparison of body composition methods in obese individuals.
TLDR
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. Expand
Seasonal variation of body composition in women.
TLDR
Of the methods at present available for estimating the proportion of body fat in living individuals, hydrostatic weighing is the most reliable. Expand
Body composition methodology
The tissues of the body are acquired from and exchanged with the environment. Nutritional status is an index of the state of this exchange and accretion. One component of this index is the amounts ofExpand
Methods of body composition analysis the status of the gold standard

  • 1993
TLDR
The prevention, treatment, and comprehension of disease processes can be advanced with improved methods for assessing changes in body composition and the "gold standard" for measuring living human subjects will likely shift from the frequently relied upon underwater weighing method to techniques that further divide the fat-free mass.

TLDR
A three-compartment model based on field-adapted methods to calculate body fat, correlated significantly with a more complex four-compartments model (UWW + BIA + DXA) (r = 0.95, p < 0.001). Expand

STUDIES ON BODY COMPOSITION II. THEORETICAL CONSIDERATIONS REGARDING THE MAJOR BODY TISSUE COMPONENTS, WITH SUGGESTIONS FOR APPLICATION TO MAN
TLDR
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. Expand
The composition of the adult human body as determined by chemical analysis.
TLDR
Analytical data on the chemical composition of the adult, human body are scant, and statistically inadequate, but an important application relates to the validity of met,abolic balance studies of nitrogen, calcium, iron, etc., as measures of the daily net requirements of humans for these nutrients. Expand
THE SPECIFIC GRAVITY OF HEALTHY MEN: BODY WEIGHT ÷ VOLUME AS AN INDEX OF OBESITY
TLDR
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. Expand
The chemical composition of the tissue lost by obese patients on a reducing regimen.
TLDR
An analysis of the composition of obesity tissue lost by the seven patients on the reducing regimen described in the preceding paper is presented. Expand
Density, fat, water and solids in freshly isolated tissues.
TLDR
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. Expand
The chemical composition of the adult human body and its bearing on the biochemistry of growth.
TLDR
The extent to which metabolic balances of nitrogen, calcium, iron, etc., actually measure the day to day requirements in terms of net nutrients’ can be judged by comparing their total integration throughout growth with the composition of the mature body with respect to them. Expand
Fat, water and tissue solids of the whole body less its bone mineral.
TLDR
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. Expand
