The purpose of this study was to investigate the comparison of fat oxidation on different exercise intensities among the
Korean type II diabetes female. 30 type II diabetes female Subjects who were classified as overweight or obesity were recruited in
this study. They performed maximal exercise test on the cycle ergometer, and than exercise intensities(40%, 50%, 60%,, 70% and
80% of hear rate reverve:HRR) were determined. After a week, they performed five four minute steady-state exercises at 40, 50,
60, 70, and 80% of HRR on the cycle ergometer under the 12-hour fasting condition. The fat oxidation were calculated by indirect
calorimetry from gas exchange measurements according to the non-protein respiratory quotient technique and using stoichiometric
equations. The fat oxidation rate was the highest in 50% of HRR(119.6 ± 14.1 mg/min), and the fat oxidation in 50%and
60%(111.8 ±12.4 mg/min) of HRR significantly higher than in 40%(96.5 ± 8.9 mg/min), 70%(92.5 ± 7.3 mg/min), and 80%(37.4 ±
3.4 mg/min) of HRR, respectively. However, there was no different fat oxidation between 50% and 60% of HRR. In addition, the
fat oxidaiton in 80% of HRR was statistically lower than the fat oxidation in other intensities. In conclusion, the 50% and 60% of
HRR may have more fat oxidation, and may be suitable exercise intensity for Korean type II diabetes female.
