Figure 2. Intestinal permeability was evaluated by the percentage of lactulose, mannitol, and lactulose/mannitol ratio. Animals were subdivided into 5 groups: sedentary without supplementation (S), trained animals without supplementation (T), trained animals supplemented with alanyl-glutamine (T-AG), trained animals subjected to an exhaustive test without supplementation (ET), and trained animals subjected to an exhaustive test and supplemented with alanyl-glutamine (ET-AG). The data are reported as means±SD (n=8). *P<0.05 compared with S; ^#P<0.05 compared with ET (ANOVA followed by Bonferroni post hoc test).
