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.

* p<0.05 represents the comparison of means between the CON vs DS groups. #p<0.05 is the comparison of the mean values between the groups DE vs DS. Statistical differences between means were determined by two-way ANOVA test followed by Bonferroni post-test (inter-group)
* Statistical analysis was performed using an ANOVA test via followed by Bonferroni post-test (inter-group) (p <0.05)
* Statistical differences between means were determined by Student's t test unpaired (*p <0.05).
* Values are expressed as means (± standard error). The ANOVA two-way was used, followed by Bonferroni post-test. *p<0.05 represents the comparison of means between CON vs DS groups. #p<0.05 is the comparison of the mean values between the groups DE vs DS
*p< 0,05 is the comparison of means between groups CON vs DS. #p < 0,05 is the comparison of means between groups DE vs DS. Statistical differences between means were determined by the one-way ANOVA followed by Bonferroni post-test
