Maximal Fat Oxidation Rates in an Athletic Population.

Introduction: The aim of this study was to describe maximal fat oxidation (MFO) rates in an athletic population. Method: In total, 1121 athletes (933 males, 188 females), from a variety of sports and competitive level, undertook a graded exercise test on a treadmill in a fasted state (>=5 h fasted). Rates of fat oxidation were determined using indirect calorimetry. Results: Average MFO was 0.59 +/- 0.18 g[BULLET OPERATOR]min-1, ranging from 0.17 - 1.27 g[BULLET OPERATOR]min-1. Maximal rates occurred at an average exercise intensity of 49.3 +/- 14.8% V[spacing dot above]O2max, ranging from 22.6 - 88.8% V[spacing dot above]O2max. In absolute terms, male athletes had significantly higher MFO compared to females (0.61 and 0.50 g[BULLET OPERATOR]min-1 respectively, P
