Effect of Different HIIT Protocols on the Glycemic Control and Lipids Profile in Men with type ۲ diabetes: A Randomize Control Trial

Objective: : High intensity interval training (HIITs) can induce weight control, lowering blood pressure and beneficial effects on cardiovascular health in type ۲ diabetic patients. The effect of different volumes of these exercises is unclear in type ۲ diabetic patients. The aim of this study was to compare the effect of low volume and high volume of short-term intensive training on glycemic indexes of men with type ۲ diabetes. Materials and Methods: Thirty type ۲ diabetes male patients who were referred to Yazd diabetes research center (۳۰ - ۴۶ years old) were selected and randomly divided into ۳ groups of low and high volume HIITs groups and control group. The intensity of the exercises in low volume was up to ۱۱۰% and in high volume up to ۸۰% of the maximum heart rate. The two training groups performed exercises ۳ days of week for ۸ weeks. Glycemic factors and lipids profile were measured before and after the last training session. Data were analyzed by covariance and paired T-test. Results: Low volume HIIT exercises significantly decreased the glucose (P-value: ۰.۰۱), HbA۱c (P-value: ۰.۰۱), insulin (P-value: ۰.۰۰۵), insulin resistance (P-value: ۰.۰۰۱), and triglyceride (P-value: ۰.۰۴). Low volume HIIT in the insulin resistance had a significant difference with the control group (P-value: ۰.۰۴). High density lipoprotein in high volume group had a significant difference with the control group (P-value: ۰.۰۲۱). Conclusion: Low-volume HIIT exercises can be a non-pharmacological approach to improving glycemic factors in type ۲ diabetic patients.
