S: sedentary; T: trained; T-AG: trained and supplemented with alanyl-glutamine; ET: trained and subjected to an exhaustive test; ET-AG: trained group supplemented with alanyl-glutamine and subjected to an exhaustive test; BE: base excess; HCO₃ ^-: bicarbonate; pCO₂: carbon dioxide partial pressure; pO₂: oxygen partial pressure: SatO₂: oxygen saturation. Data are reported as means±SD. *P<0.05 compared to S group; ^#P<0.05 compared to T group (ANOVA followed by Bonferroni post hoc test).
