How does the BOD POD testing work?

The BOD POD Gold Standard Body Composition Tracking System is an easy, ten-minute test that calculates the client’s weight and volume using an exact electronic scale that is evaluated by sitting inside the BOD POD chamber. It uses patented Air Displacement Plethysmography in identifying the percent fat and fat-free mass both in adults and children.

There are two (2) chambers of the BOD POD test. The front testing Chamber to where the client sits and is covered by a seat that forms a common wall separating it from the rear, or the Reference Chamber. The chamber door is protected by a set of electromagnets and a gasket throughout the short data collection period of the volume measurement. Likewise, a Diaphragm is attached to the standard wall that oscillates throughout the BOD POD testing, which causes minor changes in volume inside the chamber. These little changes in volume measure the pressure response. Two (2) measurements are being done: the first is measuring the interior volume of the BOD POD chamber while still empty, and the second measurement is when the client is seated inside. By subtraction, the client’s body volume is acquired. For illustration, if the interior air volume of the empty chamber is 400 liters, and the magnitude of the chamber is reduced to 350 liters with the client inside, the body volume of the subject would be 50 liters. Once the client’s mass and volume are identified, the body density is computed, and the relative percentage of fat and fat-free mass is determined.
