Effects of the acute physical exercise on glycaemic and lipids levels in diabetic rats treated with metformin

Abstract

The aim of the study was to investigate the effects of the acute physical exercise on the glycaemic and lipids levels in diabetic rats treated with metformin. For the induction of the type 1 diabetes, the rats were maintained in fasting for 24 hours with free access to water. After anesthesia with ether, the rats received an intravenous injection of alloxan (32 mg / kg b.w.). Adult (130 days) male Wistar rats were divided in two groups: diabetics metformin (DM) and diabetics control (DC). The animals of the group DM received metformin in water (1,4 mg / ml) for 15 days. The blood samples were collected before and immediately after a swimming session (30 min) without additional load. The results revealed that the metformin administered (110 mg / kg / day) by itself or combined with the acute physical exercise didn't promote significant alterations in glucose, triglyceride and cholesterol concentrations in experimental diabetic rats. Other studies are necessary to test different metformin doses with regular sessions of physical exercise in type 1 diabetes.
