Comparison of body density and precent body fat as computed using four different lung volumes in the hydrostatic weighing technique

Abstract

This study compared body density (BD) and percent body fat (%BF) arrived at by using four different lung volumes in the hydrostatic weighing (HW) procedure. The four lung volumes were residual volume as measured in air (RV-dry), residual volume as measured immersed in water (RV-wet), functional residual capacity,as measured immersed (FRC), and total lung capacity as measured immersed (TLC). The closed circuit oxygen dilution technique was used to measure all lung volumes.
