EFFECTS OF HIGH INTENSITY ACUTE RESISTANCE EXERCISE ON BLOOD GLUCOSE AND INSULIN SENSITIVITY IN RATS WITH INSULIN RESISTANCE

ABSTRACT The aim of the study was to evaluate the acute resistance exercise on glucose metabolism in animals with insulin resistance. 30 Wistar rats were divided into three groups: control (CON), Dexamethasone Sedentary (DS) and dexamethasone + exercise (DE). Resistance exercise was conducted in the squat machine consisting of five sets, 10 repetitions, with intensity of 70% of 1RM. Concurrently, the DS and DE groups received daily intraperitoneal dexamethasone (4.0mg / kg). The body weight, glycemia and insulin sensitivity test were measured in all groups. One single resistance exercise session reduced blood glucose levels and improved insulin sensitivity. The DT group showed a lower area under the curve when compared to the DS group. The high intensity acute resistance exercise promoted a reduction of blood glucose levels and improved insulin sensitivity in rats with insulin resistance dexamethasone- induced.
