The BOD POD uses Air Displacement Plethysmograph (ADP) to determine your body composition (the ratio of fatty mass to lean mass). Body composition is divided into two body mass categories (fat mass & lean mass).
Fat mass consists of all the adipose tissue (fat) within your body. Lean mass consist of bone, bodily fluid (blood), organs, and skeletal muscle. The BOD POD test provides results of these two categories expressed as percentages of total body mass.
Body composition testing may feel uncomfortable for the parties involved. We strive to create an atmosphere in which our participants feel respected and at ease by refraining from inappropriate comments and behaviors. By entering our space, you are also agreeing to meet this expectation. Failure to do so may result in cessation of the testing session.

Body composition measurements from the BOD POD have been found to be equivalent (no statistically significant difference) to those obtained using 4-compartment model reference techniques. The BOD POD is also referred to as the “Practical Gold Standard” because testing is so easy and offers excellent repeatability.
The BOD POD Gold Standard Body Composition Tracking System uses patented Air Displacement Plethysmography for determining percent fat and fat-free mass in adults and children. The simple, 10-minute test consists of measuring the subject's mass (weight) using a very accurate electronic scale, and volume, which is determined by sitting inside the BOD POD chamber. From these two measurements, the subject's body composition is calculated.
The BOD POD consists of two chambers. The front, or Test Chamber, is where the subject sits and is comprised of a seat that forms a common wall separating it from the rear, or Reference Chamber. During the brief data collection period of the volume measurement, the chamber door is secured by a series of electromagnets and a gasket. A Diaphragm is mounted on the common wall, which oscillates during testing. This causes small changes in volume inside the chamber, of which the pressure response to these small volume changes is measured. This is done by measuring the interior volume of the empty BOD POD chamber, then measuring it again when the subject is seated inside. By subtraction, the subject's body volume is obtained. For example, if the interior air volume of the empty chamber is 400 liters, and the volume of the chamber is reduced to 350 liters with the subject inside, the body volume of the subject would be 50 liters.
Once the subject's mass and volume are determined, body density is calculated and the relative proportions of fat and fat-free mass are determined
A complete test, including printed results, takes about 10 minutes. PEAK schedules 30-minute appointments to allow for paperwork and explanation of results.
The BOD POD is designed to accommodate a wide variety of human shapes and sizes. Because of its generous-sized interior and oversized window, NFL and NBA teams, as well as sumo wrestlers use the BOD POD routinely without difficulty. The BOD POD can accommodate subjects up to 7 feet tall and 550 pounds.
Clothing, hair, jewelry, and eyeglasses can have a significant impact on the volume and mass measurements performed during a BOD POD test. Therefore, it is EXTREMELY IMPORTANT that all subjects tested in the BOD POD remove all jewelry and eyeglasses, and wear minimal, form-fitting clothing such as a Lycra® or Spandex® swimsuit during testing. Single-layer compression shorts and/or lightweight jog bras are also acceptable clothing (without padding or wires).
A swim cap must also be worn to compress any air pockets within the hair.
Participant compliance for testing in the BOD POD is very simple. You need only to sit comfortably and quietly inside the BOD POD for the brief measurement period (no talking or laughing). Sounds relating to valves opening and closing may be heard, but most people are unaware of the slight pressure changes that take place during a BOD POD test. A few people have noted a feeling similar to that of moving from the first to second floor in an elevator.
No. Subjects should wait at least two hours after exercising or eating, and always be in a completely relaxed state (normal breathing) when testing in the BOD POD.
