The effect of branched amino acids and carbohydrate consumption on some indexes of muscle damage in active men after a session of aerobic exercise" was the aim of our study. Materials & Methods: In this study, 30 active male students were selected and divided into three groups control; branched amino acids and carbohydrate taking groups. "Shuttle run test" was the type of exhaustive aerobic test in our study. One hour before the test, studied groups received 210 mg/kg/ branched amino acids or carbohydrate, subjects in the control group received the same amount placebo. Blood sample was taken before, immediately after, 24 and 48 hour after finishing the exercise. Analysis of variance with repeated measurements and Bonferroni post hoc were used for data analysis, and P≤0.05 was considered statistically significant. Results: Statistical analysis showed that serum levels of CK, LDH, AST and ALT all were increase in all groups at different defined times after the test (P<0.05). Post exercise levels of AST and ALT were significantly lower in branched amino acids group and the different was significant with carbohydrate and control group at different times of measurement (P<0.05). Conclusions: Consumption of branched amino acids before exhaustive aerobic exercise has a protective effect and prevents further muscle damage.
