About
The purpose of this study is to compare RMR values from the BIA, predicted equations, and indirect calorimetry.
Full description
Resting metabolic rate (RMR) describes the number of calories a person utilizes while at rest. The gold standard measurement is via inspired and expired air using a metabolic cart. However, researchers have established estimation equations and the use of body composition analysis to predict RMR when a metabolic cart is unavailable. The accuracy of the predicted equations and whole-body bioelectrical impedance (BIA) machines that produce this data is unknown. Therefore, the purpose of this study is to compare RMR values from the BIA, predicted equations, and indirect calorimetry.
Aim 1: to compare measured RMR from indirect calorimetry to values provided by the InBody 770 BIA machine and to established gender and age-appropriate prediction equations.
Aim 2: to compare RMR measured from indirect calorimetry using a metabolic cart (Gold Standard) to the Medgem handheld indirect calorimeter (FDA approved device).
