Effects Of Different Exercise Mode On Fat Metabolism Rate In Type 2 Diabetic Patients

Objective:The study aimed to observe the effects of different exercise mode (the treadmill exercise and power bicycle exercise) on fat metabolismrate in type 2 diabetic patients.Methods:Selected 20 type 2 diabetic patients from October 2014 to December 2014, who were hospitalized in Department of Endocrinology, Zhongda Hospital, Southeast University to do thecardiopulmonary exercise test and the exercise mode was randomized. The subjects should do two exercises and use the gas metabolism analysis instrument (K4b2) to do the exercise program with same intensity and time. We collected the oxygen uptake, carbon dioxide emissions, heart rate, blood pressure and other index during the exercise, monitored the blood glucose before and after the exercise, and calculate the fat oxidationrate of different exercise mode. Measurement data were expressed as means with standard deviations and analyzed by SPSS 18.0 for windows. Means of every two different groups were detected using thepaired samples t test. The correlations between the variables were compared using pearson correlation coefficient. p<0.05 was considered as statistically significant.Results:1、Afterthe two different exercises, the blood glucose of the type 2 diabetic patientswere decreased significantly (p<0.001); 2、Under the same intensity and time and different exercise mode, thetarget heart rate、RPP、PRE、VE/VO2 and RQ of the subjects who did the power bicycle exercise were significantly higher than the subjects who did the treadmillexercise (p=0.008、 p=0.031、p=0.030、p<0.001 and p=0.002). On the contrary, the VO2、VO2/kg, fat oxidation rate and per kilogram fat oxidation rate were significantly even less than the subjects who did the treadmill exercise (p<0.001、p=0.004、p<0.001 and p<0.001), and the other indexes such as blood glucose、the difference between blood glucose、blood pressure、the difference between blood pressure and other gas metabolism indexes had no statistically differences; 3、Either of the normal weight or overweight subjects, the fat oxidation rate and per kilogram fat oxidation rate of the treadmill exercise were significantly higher than the power bicycle exercise(p<0.05); No matter the exercise mode was treadmill or power bicycle, the subjects who were normal weight and overweight, their fat oxidation rate and per kilogram fat oxidation rate had no significantly differences (p>0.05); 4、No matter the treadmill exercise or the power bicycle exercise, the changes of the subjects’ weight、BMI、waistline, hipline and waist-hip ratiohad no obvious consistency with their fat oxidation rate. the pearson correlation coefficient were all less than 0.2.Conclusion:1、In the condition of exercising with same intensity and time, the hypoglycemic effect was similar, it meant that the exercise mode was not the determinant of the control of blood glucose;2、In the condition of exercising with same intensity and time, the changes of the type 2 diabetic patients’ weight、BMI、waistline、hipline and waist-hip ratiohad no obvious consistency with their fat oxidation rate, it meant that type 2 diabetic patients’ bodily form had nothing to do with their fat oxidation rate;3、In the condition of exercising with same intensity and time, thetarget heart rate and PRE of the patients with type 2 diabetes who did the power bicycle exercise was significantly higher than the subjects who did the treadmillexercise, but the fat oxidation rate was significantly even less than the subjects who did the treadmill exercise, it prompted that treadmill exercise was more lighten and more conducive than power bicycle exercise to fat metabolism and to reduce fat in type 2 diabetic patients, but the mechanism was still need to further study.
