Introduction: Obesity, sedentary, and vitamin D deficiency are closely linked to diabetes. The aim of this study was to determine the effect of eight weeks of aerobic exercise on plasma levels of vitamin D and glycemic control indicators in type 2 diabetic patients.
Materials and Methods: From among males with type 2 diabetes, 24 patients with mean age (49.5±0.81 years) and BMI (29.6±1.3 kg/m2) were randomly divided into two groups including aerobic exercise (n=12) and control (12 people). The aerobic exercise program was performed for eight weeks with an intensity of 50 to 75% of the heart rate reserve. Levels of vitamin D, HbA1c, glucose, insulin, insulin resistance, insulin sensitivity and beta cell function were measured in the pretest and posttest. Dependent t-test and analysis of covariance were used for intragroup and intergroup comparison and Pearson correlation test was used for the measurement of variables relationship.
Results: The results showed that the percentage of HbA1c, glucose, insulin and insulin resistance in the aerobic exercise group had a significant decrease compared to the control group (p<0.05), However, vitamin D levels, insulin sensitivity and beta cell function in the aerobic exercise group increased significantly compared to the control group (p<0.05). In addition, the results of Pearson correlation test showed a significant relationship between vitamin D levels and glycemic control indicators in the aerobic exercise group (p<0.05).
Conclusion: In this study, it was observed that aerobic exercise is an effective strategy to improve glycemic control indicator in type 2 diabetic patients. This supportive effect is probably related to the development of plasma levels of vitamin D.
