This plethysmographic measurement chamber prevents the accumulation of water vapor and carbon dioxide in the chamber, it addresses variations in chamber temperature due to body heat produced by the subject, and it maintains a safe and comfortable air composition for infants. Air displacement plethysmography (bod pod) What You Do. Therefore, based on the body of literature that has emerged, air-displacement plethysmography appears to be a suitable and reliable instrument in the assessment of body composition. Percent body fat estimations in college men using field and laboratory methods: A three-compartment model approach. doi: 10.1371/journal.pone.0267089. The amplitude of the pressure fluctuations is determined and is used to determine the amount of air in the chamber through Boyles Law (isothermal conditions) or Poissons Law (using adiabatic conditions). Fat has a lower water content than muscle or connective tissues, therefore more fat will slow down, or impede, the electrical current. The volume of air inside the chamber is calculated by slightly changing the size of the chamber (e.g. About | Bailey, B.W., LeCheminant, G., Hope, T., Bell, M. and Tucker, L.A., 2018.

Air displacement plethysmography or ADP (also known as whole-body air displacement plethysmography) is a recognized and scientifically validated densitometric method to measure human body composition. and only a few facilities have it. 5. The purpose of this study was to examine the reliability of an air displacement plethysmography device (BOD POD) over trials performed on 3 different days. Accessibility In these experiments, ADP and UWW were found to be valid laboratory methods for body composition assessment [23, 24]. 2. ADP is based on the same principles as the gold standard method of hydrostatic weighing, but through a densitometric technique that uses air displacement rather than water immersion. It can be measured by different methods, including skinfold thickness measurements, bioelectrical impedance analysis (BIA), underwater weighing, dual-energy x-ray absorptiometry (DXA), or air displacement plethysmography. Comparison of body composition techniques to determine body fat in high school wrestlers. Body volume is calculated indirectly by subtracting the volume of air remaining inside the chamber when the subject is inside from the volume of air in the chamber when it is empty. These results indicate a high reliability for within-day estimates of BF and significant differences in between-day estimates of BF using air displacement plethysmography. DXA can estimate the breakdown of (1) lean mass, (2) fat mass, and (3) bone mineral content, by body segment, because each tissue differentiates photons differently. Also Read: The Hidden Dangers Of Excessive Body Fat. Resting Energy Expenditure Is Not Altered in Children and Adolescents with Obesity. Advantages / Disadvantages Good energy efficiency potential Air quality is generally better compared to fan coil units (FCUs) or variable air volume (VAV) systems due to the lack of mixing of air within the space If you become less buoyant over time, you have reduced your percentage of body fat (i.e. Using the known fat mass and typical fat-free mass densities in humans (0.9 g/cm3 and 1.1 g/cm3, respectively), an equation is applied to estimate body composition. Therefore, the density of fat mass (0.9 g/cm3) is relatively constant. Theres a substantial body of research that suggests body composition estimation from UWW and ADP can be more accurate when combined with TBW assessment [1, 2, 42-47]. pre-test: Explain the test procedures to the subject. accuracy: The manufacturers indicate that the general error range of the BOD POD is 1-2% (the same as hydrostatic weighing). Khaira S, Pert A, Farrell E, Sibley C, Harvey-Wilkes K, Nielsen HC, Volpe MV. 1961. Collins AL, Saunders S, McCarthy HD, Williams JE, Fuller NJ. Body weight is measured using scales.
