Effects of eccentric and concentric exercises on some blood biochemical parameters in patients with type 2 diabetes

About 7% of world populations suffer from diabetes disease and its widespread complications. There are several studies about the beneficial effects of aerobic and resistance exercises on blood glucose and lipids levels, insulin sensitivity in type 2 diabetic patients. However, there is no study to investigate the effects of eccentric exercise in these patients. This study was designed to compare the effect of eccentric and concentric exercises on some of the blood biochemical parameters in type 2 of diabetic patients.

28 type 2 diabetic patients were assigned randomly in one of the two experimental eccentric and concentric groups. Before and after control and also after intervention, blood sugers, HbA1c, lipids and body mass index were measured.

The results showed that eccentric and concentric exercises result in a significant decrease in blood sugar, HbA1c, and blood lipids. Eccentric exercise training also significantly reduced blood sugar levels and HbA1c compared to the concentric exercise (P<0.0001). Moreover, no significant changes were found in blood lipids levels in regard to the type of exercise.

Our findings show that eccentric exercise is more effective than concentric exercise with respect to reducing and controlling blood glucose levels in type 2 diabetic patients.
