Hydrostatic weighing (HW) was performed at both residual volume (RV) and functional residual capacity (FRC) to determine if underwater weighing at different lung volumes affected the measurement of body density. Subjects were 43 males, 18-25 yr. Subjects were submerged in the prone position, and the lung volume was measured by helium dilution at the time of the underwater weighing. Underwater weight was first assessed at FRC followed by assessment at RV. Changes in lung volume were accurately… Expand
A hydrostatic weighing method using total lung capacity and a small tank.
TLDR
It was concluded that the TLC prone (tank) method is valid, reliable and a favourable method of hydrostatic weighing. Expand

Total lung capacity, residual volume and predicted residual volume in a densitometric study of older men.
TLDR
TLC and RV may be used comparably during HWDs, but a PRV may produce significantly different values; since HWD at TLC is easily performed and circumvents the difficulties associated with the RV technique, it may be the preferred method for older subjects. Expand
Comparison of two hydrodensitometric methods for estimating percent body fat.
TLDR
Whereas both methods were precise and reliable and yielded similar results, the oxygen dilution technique was more expedient and was preferred by the subjects because they were not required to exhale to RV. Expand

TLDR
The BB technique appears to be an accurate substitute for the chair/scale technique for hydrostatic weighing and could be improved with the use of multiple bottles of various volumes or a calibrated bottle to minimize the number of trials needed for accurate measurements. Expand
Dietary preparation and per cent fat measurement by hydrostatic weighing.
TLDR
The results indicate that for the most accurate analysis, preliminary dietary preparation for HW should include food and beverage restriction. Expand

Higher Muscle Tissue Oxygenation When Exposed To Hypobaric Hypoxia Than Normobaric Hypoxia
TLDR
The data indicate that the hypoxic stresses resulting from normobaric and hypobaric hypoxia are not the same and that Hypobaric Hypoxia may not result in hypoxIA at the level of the tissue. Expand

SummaryMethods of in vivo body fat estimation are based on simple assumptions about body composition which work reasonably well for men, while estimations in women have been largely extrapolated fromExpand

TLDR
Densitometric analysis was made on each subject using hydrostatic weighing techniques and it was concluded that when obtaining body density values, RV should be measured concurrently while the subject is in the water. Expand
Lung volumes in man immersed to the neck: dilution and plethysmographic techniques.
TLDR
During immersion the dilution residual volume was 0.200 liter (16%) lower than the plethysmographic value (P greater than 0.001), which suggests that there is a significant amount of gas trapping during immersion due to breathing at low lung volumes and the central shift of blood. Expand
