Abstract
Introduction: The aim of this study was to compare the effect of continuous moderate-intensity and high-intensity interval training along with a calorie-restricted diet on resting metabolism and lipid profile in type 2 diabetes.
Methods: In a randomized-controlled trial, 42 overweight or obese type 2 diabetic subjects were randomly assigned to 3 groups: continuous training (CT), interval training (IT), and control. Continuous training (at 55%-65% of the heart rate reserve) and interval training (intervals of 1 minute at 85-90% of the heart rate reserve interspersed with 1 minute walking at 40-45% of the heart rate reserve) were carried out 3 days a week over 12 weeks and through Bout the intervention the participants received a diet with 20% calorie deficit. Before and 48 hours after the last training session, measurements including body composition,
Results: both CT and IT decreased weight, body mass index, triglyceride, total cholesterol (p < 0.05), but had no significant effect on resting metabolic rates, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) compared to the control group (p>0.05). There was no significant difference between the experimental groups (CT vs IT) (p < 0.05).
Conclusion: It seems that calorie expenditure of exercise training is more important than the intensity in weight-loss and improving metabolic profile. High-intensity interval training in a lower exercise volume and with equal energy consumption seems to be as effective as moderate-intensity continuous training.
