The doubly labeled water technique
WebThe doubly labeled water (DLW) technique is used to assess meta-bolic rate (MR) in free-living conditions. We investigated whether differences in the nutritional and body adiposity status affect validity of the assessment of CO 2 production (rCO 2) by the DLW technique. To serve this purpose, we compared calculated rCO 2 by the DLW method to ...
