effect of different hiit protocols on the glycemic control and lipids profile in men with type 2 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 2 diabetic patients. the effect of different volumes of these exercises is unclear in type 2 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 2 diabetes. materials and methods: thirty type 2 diabetes male patients who were referred to yazd diabetes research center (30 - 46 years old) were selected and randomly divided into 3 groups of low and high volume hiits groups and control group. the intensity of the exercises in low volume was up to 110% and in high volume up to 80% of the maximum heart rate. the two training groups performed exercises 3 days of week for 8 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: 0.01), hba1c (p-value: 0.01), insulin (p-value: 0.005), insulin resistance (p-value: 0.001), and triglyceride (p-value: 0.04). low volume hiit in the insulin resistance had a significant difference with the control group (p-value: 0.04). high density lipoprotein in high volume group had a significant difference with the control group (p-value: 0.021). conclusion: low-volume hiit exercises can be a nonpharmacological approach to improving glycemic factors in type 2 diabetic patients.
