Introduction: Cardiovascular diseases are the major consequences of diabetes and the prime reason of mortalities of the human being. Accordingly, exercise can prevent from the consequences of diabetes that has become massively prevalent among the societies in the recent years. Although the expedient hand of aerobic exercises has been emphasized always, but the private attention to the resistance exercises (especially, circular resistance workouts) as therapeutic exercises is a new focus. Circular resistance exercises can be performed in two fashion of either continuous (moderate intensity) or intermittent (high and low intensities) with the very same duration. The purpose of the present study was determination and comparison of eight week continuous and intermittent resistance exercises on serum levels of glycosylated hemoglobin, triglyceride, total cholesterol, LDL, HDL, and LDL to HDL ratio in type-2 diabetic women with BMI of greater than 25.
Methodology: Thirty type-2 diabetic overweight women were randomly divided into three groups of continuous resistance exercise, intermittent resistance exercise, and control (10 subjects for each group). The two exercise groups participated in a period of circular resistance workouts (either continuous fashion with moderate intensity or intermittent one with high and low intensities) during eight weeks. The control group did not follow any exercise schedule and only did their usual daily activities. Blood samples were collected from the three groups, both 24 hrs before and 48 hrs after the intervention. Mixed Between-Within Subjects ANOVA was employed to compare and investigate variations of the variables, setting the significance level as P≤0.05.
Results: Eight weeks resistance exercises would cause significant decreases in glycosylated hemoglobin, triglyceride, total cholesterol, LDL, and LDL to HDL ratio of the exercise groups comparing to those of the control group (P<0.05). However, no significant difference was observed between the two exercise groups (P>0.05). Although HDL of the two exercise groups increased, but the increases were not significant (P>0.05).
Discussion: Eight weeks (3 weekly sessions) circular resistance exercises (either continuous or intermittent) with increasing volume training would imprint its positive changes on type-2 diabetic women with BMI of greater than 25. Therefore, the resistance exercises may be paid attention by the penitents to prevent from the cardiovascular diseases resulted from diabetes.
