This study compared Fatmax and maximal fat oxidation (MFO) for the most efficient fat oxidation in fat metabolism during exercise and reviewed their relationship with cardiorespiratory fitness (CRF). The subjects were 27 adult women under 20~30 years of age who chose regular exercise habits over 150 min/wk. Subjects were classified into obese group (22.6±3.3 yrs, n=13) and normal group (23.6±3.4 yrs, n=14) according to the BMI criteria (<25 ㎏/㎡). Fatmax test was calculated according to Weir et al. (1949) through the exercise load test. MFO was the Fatmax stage: 1) highest level of fat oxidation (individual MFO ratio), 2) average fat oxidation of 6 minutes, and 3) average fat oxidation of the last 2 minutes (MacRae et al., 1995). As a result, the CRF (VO₂max) was higher in the obese group than in the normal group (p=.026), but the relative value (p=.291) did not show a difference in weight effects of the obese group. There was no difference between MFO (0.3±0.2 g/min vs. 0.4±0.2 g/min) and Fatmax (47.9±10.4% vs. 48.8±9.1%) in the obese and normal groups (p>.05). There was also no difference in resting fat oxidation (0.051±0.05 g/min vs. 0.052±0.59 g/min) and carbohydrate oxidation (3.05±1.12 g/min vs. 3.38±0.97 g/min). Fatmax was not significantly correlated with VO₂max and r=.192 (p=.270) and %fat with r= -.034 (p=.871). The results showed that MFO and Fatmax were similar in obese and exercised groups. Because of the higher VO₂max in the normal population, it is thought that it is more likely to have MFO that occur at higher absolute intensity than the obese group.
