<h3>What is Plethysmography?</h3>
Air displacement plethysmography (ADP) is a two-component model which assesses mass and volume of a body and therefore an estimation of body density. Body density can be derived from mass divided by the volume of body which can provide the estimation of fat and fat-free mass (FFM).
Plethysmography uses air displacement for the determination of body mass. Plethysmography is commonly conducted using a machine known as the BOD POD that uses the whole body air plethysmography to measure body composition.
