How does the BOD POD® determine body composition?
The principle underlying the BOD POD® is whole body densitometry: Body density (Db) = mass / volume Mass is obtained by weighing the individual on an accurate scale included with the BOD POD®. Volume is determined using the BOD POD’s egg-shaped air displacement plethysmograph. Db can then be converted to percent body fat using one of several population-specific conversion formulas or used in combination with other body composition measurements (eg, mineral and total body water) to calculate percent body fat. How accurate is the BOD POD®? The BOD POD® has been shown to accurately and reliably measure the volume of inanimate objects (Dempster and Aitkens, 1995) and the percent body fat of humans when compared with values obtained from hydrodensitometry (ie, under water weighing) (McCrory et al, 1995). Numerous published studies have compared the BOD POD® with other body composition methods in various population groups. The BOD POD® and hydrodensitometry are based on a body composition mo
