This study was aimed to compare the maximal fat oxidation exercise intensity(MFOEI) by physcal fitness(VO₂max and VT) and compare heart rate(HR), respiratory exchange ratio(HER), total kilocarolies per minute(Tkcal), and fat kilocarolies per minute(Fkcal) in this exercise intensity. Fifty one healthy young volunteers(33 men, 18 women) served as subjects after signing an informed consent form. Following an overnight fast, each subject completed stretching and tree minute warm-up at 3.0mph of speed and 10% of grade, followed by a maximal Bruce protocol treadmill test. Expired gases were collected and analyzed each one minute using Quinton metabolic cart. The MFOEI was defined as the intensity which resulted in maximal Fkcal as determined by converting VO₂ to Fkcal at each treadmill stage using RER and a Lusk table. MFOEIs as expressed %VO₂max(L/min) and %VT were not significantly difference between high VO₂max group and low VO₂max group while %VT was sigficnaltly higher in low VT group compared with high VT group, 78.1%VT and 70.5%VT, respectively(p<.05). Except for HR, the resultant of t-test for VO₂, RER, Tkcal, and Fkcal were significantly higher in high VO₂max group(p<.05). However, the percentage of fat oxidation at MFOEI was higher in low VO₂max groupn(high about 69.5%, low about 88.6%). This results may be supported the theory that physical fitness greatly influence on substrate utilization patterns during exercise. Thus, MFOEI which prescribe exercise intensity to weight control and loss is likely to be distinguish from physical fitness.
