Background: Skeletal muscle (SM) is an important body-composition component that remains difficult and impractical to quantify by most investigators outside of specialized research centers. A lar...
Calibration and validation of an air-displacement plethysmography method for estimating percentage body fat in an elderly population: a comparison among compartmental models
Body composition elderly men
2016/6/14
The use of hydrostatic weighing (HW) to measure
body composition in the elderly can be difficult and is based on
the assumption of constancy of body compartments.
