A simple, inexpensive method of determining total body water using a tracer dose of D2O and infrared absorption of biological fluids.
TLDR
An improved infrared spectrophotometric method using tracer doses of D2O for determination of total body water (TBW) is described, showing low cost and a simple analysis that permits repeated TBW measurements over brief periods without an undue buildup of background deuterium levels in the body.About:

Low relative skeletal muscle mass (sarcopenia) in older persons is associated with functional impairment and physical disability.
TL;DR: To establish the prevalence of sarc Openia in older Americans and to test the hypothesis that sarcopenia is related to functional impairment and physical disability in older persons is established.

Assessment of fat-free mass using bioelectrical impedance measurements of the human body
TL;DR: Data indicate that the bioelectrical impedance technique is a reliable and valid approach for the estimation of human body composition and further validation of this method is recommended in subjects with abnormal body composition.
Journal ArticleDOI
Validation of tetrapolar bioelectrical impedance method to assess human body composition.
TL;DR: The validity and reliability of the tetrapolar impedance method for use in assessment of body composition in healthy humans is established, with a lower predictive error or standard error of the estimates of estimating body fatness than did a standard anthropometric technique.
Journal ArticleDOI
Estimation of skeletal muscle mass by bioelectrical impedance analysis.
TL;DR: The results suggest that the BIA equation provides valid estimates of SM mass in healthy adults varying in age and adiposity.

Methods for the assessment of human body composition: traditional and new.
TL;DR: This review summarizes the physical bases and assumptions, describes applications, and discusses the theoretical and practical limitations of currently available indirect methods of estimating fat-free mass and percent body fat.

Densitometric analysis of body composition: revision of some quantitative assumptions*
TL;DR: It is shown that in a system consisting of two additive components which are mixed but the densities of which are known, the determination of the density of the system allows one to calculate the proportional masses of the two components.

Total body water measurement in humans with 18O and 2H labeled water.
TL;DR: To determine if water labeled with the stable isotope 18O can yield faster and more accurate results, total body water was measured simultaneously using waterlabeled with both 18O and 2H and the H2(18)O dilutions were measured by mass spectrometry.
