Abstract :
Measuring energy expenditure (EE) in free-living humans is difficult. In this study, we validated a novel instrument that measures free-living EE from direct calorimetry, i.e. the heat produced by the body. The sensor can be worn on the upper arm and measures all four forms of heat flux - conduction, convection, radiation and evaporation. The accuracy of this device was compared to a whole-room indirect calorimeter.
