Objective: Observe metabolic behavior and physiological adjustments promoted by a protocol of physical activities in aquatic way with the use of additional loads varying between 3 and 5% of body weight. Methods: Thirty adult male Wistar rats were randomly divided into two groups: the Trained Group (TG) and Control Group (CG). The 15 animals of the TG, which underwent physical training, were subdivided into three subgroups: GT1, GT2 and GT3. They underwent 5 weekly swimming sessions during 60 minutes, respectively totaling 3, 6 and 12 weeks of training. Insulin concentration doses, IGF, glucose and lactate at different periods and stages of protocol were used as tools to interpret possible adaptations. ANOVA ONE-WAY for unpaired data was the statistical method for glucose, insulin and IGF analysis. ANOVA TWO-WAY, statistic SAS for PC 6.08 (SAS Institute, Cary, NC) was used for plasmatic lactate. Results: No significant changes in plasmatic concentrations occurred. Conclusion: Current analysis showed that experimental model used does not induce physiological adjustments and hormone adaptations when these are analyzed by the above-mentioned methods and biochemical variables. Other researches should be undertaken involving long-term experiments coupling distinct techniques and approaches.
