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 model that divides the body into two compartments: fat and fat-free. Therefore, the accuracy of these methods depends on how well the assumptions of this model are met: • Assigned densities of fat and fat-free body are accurate • Proportions of water, mineral, and protein are constant within and between individuals • Individuals differ from the reference body only in amount of fat Three- or Four-Component Molecular models which consider the variability of water or mineral content of the fat-free body, or both, and are generally thought to p
