**Figure 3.** Association between basal metabolic rate (BMR) (**A, B**), basal fat oxidation (BFox) (**C, D**) and carbohydrate oxidation (BCHox) (**E, F**) with age. I� (unstandardized regression coefficient), R^{2} and P are from a simple linear regression analysis. Abbreviations: BMR_{LM}; Basal Metabolic Rate relative to lean mass.
