Abstract
Aim: To evaluate the effect of a ten-week strength training on the blood glucose of rats. Methods: Eighteen rats were divided into two groups: sedentary and trained. Trained animals underwent strength training for ten weeks. The animals performed four sets of eight jumps with intervals of 30 seconds during ten weeks with a frequency of 3 times per week. An overload weight was imposed to the animals, using appropriate vests, which increased every two weeks. Body weight and food consumption were evaluated weekly. At the end of the experiment, the animals were euthanized and their blood glucose and weights of visceral fat and carcass were measured. Results: No changes were observed in body weight (359.29±38.56 g vs. 355±15.58 g), food intake (162.1±16.6 g vs 156.57±5.4 g) and weight of carcass (222.5±22.7 g vs 230.7±9.3 g), however, reduction of visceral fat (17.4±3.3 g vs 12.9±1.7 g) and blood glucose (180.0±21.9 mg/dL vs. 151.7±19.6 mg/dL) was observed in the trained animals. Conclusion: The protocol used in this study reduced visceral fat and blood glucose in animals subjected to strength training
