Resumo

The purpose of this study was to determine the time to exhaustion (film) for swimming exercise at anaerobic threshold (AT) intensity in rats and to analyze metabolic consequences on serum and tissues levels. Eighteen rats were divided in control (CG) and exercised (EG) groups, being the former submitted to film. We analyzed the glycogen content of liver and ten skeletal muscles, as well as serum parameters. Parametric statistic was used with significance level at p < 0.05. The film, which was correspondent to 114.37 +/- 36.23 min, promoted significant decrease in blood glucose (42.99 %; p < 0.01) and an increase in free fatty acids (167.12 %; p < 0.01) when EG was compared to CG. We did not find differences in albumin, total protein uric acid and creatinine between groups. The proposed exercise at individualized AT intensity promoted severe glycogen depletion for all tissues (mean of 78.05 % for all muscles and 89 % for liver). With substantial control of exercise intensity, our study establishes a useful rodent model that can be further explored, contributing to the advancement on knowledge and better understanding of exhaustion mechanisms (Tab. 1, Fig. 2, Ref. 35).
