Abstract: 

The aim of this study was to comparison of maximal fat oxidation (MFO) rate in non-athletes collegiate men and women. Ten men and 10 women performed an incremental running exercise with 3 min stages on treadmill. During the test, fat oxidation rate was measured by indirect calorimetry method. Maximal fat oxidation (MFO) and the exercise intensity at which MFO occurred (Fatmax) were determined in each subject. Using independent t-test to compared between groups. Absolute fat oxidation rate (g/min) in men was significantly higher than women in all relative exercise intensities (P £0.05). But in relative fat oxidation rate (g/min/kg ffm) no difference was observed between groups. MFO in men was significantly higher than women (0.26±0.07 and 0.17±0.05 g/min respectively; P £ 0.05). Nonetheless, MFO was occurred in same exercise intensity in men (41.1±7.7 VO2max %) and women (40.2±7.8 VO2max %). CHO oxidation rate in men was higher than women in exercise intensities above 40% VO2max and proportion of fat oxidation in exercise energy expenditure has no significant difference between groups. The changes in fat oxidation defined by VO2max and FFM were 56 percent. However, the results of present study shown that men have higher fat oxidation and MFO than women but women may be have higher fat oxidation than men if they matched together by fitness and muscular mass.
