WebDec 11, 2007 · The doubly labelled water (DLW) method is an isotope-based technique for the estimation of the CO 2 production, and hence energy expenditure, of free-living animals. Estimates of field metabolic rate (FMR) from DLW in pinnipeds to date are extremely high and at the upper range for most mammals. DLW has previously been validated in … WebThe results confirm that the doubly labeled water method can be an accurate technique for the measurement of energy expenditure in adult human subjects in some laboratories. However, there was substantial between-laboratory variability in the results and some laboratories returned physiologically impossible results.

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 ... grilling on a z grillWebThe doubly labeled water (DLW) technique was developed as a method for measurement of free-living energy expenditure in animals (Lifson and McClintock, 1966).
