The Gold Standard

The BOD POD Gold Standard Body Composition Tracking System is the world’s only air displacement plethysmograph which uses whole-body densitometry to determine body composition (fat and fat-free mass) in adults and children.

A full test can be completed in a few minutes, and provides highly accurate, safe, comfortable, and fast test results. The accuracy of the BOD POD has been shown to be very high against reference techniques in a number of research publications. It is also completely non-invasive, making it especially suitable for frequent, longitudinal tracking of body composition and metabolic changes over time.


► Gold Standard accuracy using whole-body densitometric principles
► Excellent test-to-test repeatability
► Fat and Fat-Free Measurements
► Fast test time (2 minutes inside BOD POD and about 5 minutes total test time)
► Safe, non-invasive, and ideally suited for frequent testing
 

 

The BOD POD’s air displacement plethysmography eliminates the invasiveness of Dual Energy X-Ray Absorptiometry (DXA) as well as the difficulties associated with underwater submersion in hydrostatic weighing.

This makes it especially suitable for frequent, longitudinal tracking of body composition changes over time.

 

The BOD POD is used in a wide variety of segments:

► Academic and Medical Research
► Clinical Examination
► Elite Athletic Training
► Military and Public Safety
► Personal Training and Nutrition Counseling
► Bariatric Clinics
► University Fitness

 

Accuracy

The BOD POD uses the principles of whole-body densitometry to determine body composition. This technique relies on a mass measurement from a highly accurate scale (provided) and a volume measurement from the BOD POD chamber.

Once body density is determined (Density= Mass/Volume), the BOD POD measures or predicts Thoracic Gas Volume (TGV) and then uses known (or user-customized) densitometric equations to calculate percent Fat and Fat-Free Mass.

The accuracy of the BOD POD has been shown to be very high against reference techniques in a number of research publications.

Simple and easy for both subject and operator, it accommodates a wide range of subjects up to a maximum weight of 250kg.
