Abstract

Background: A few studies were done to examine the effect of different dosage of branched-chain amino acid (BCAA) supplementation on serum indexes of muscle injury in wrestlers. The purpose of this research was to compare the effects of two dosage of branched-chain amino acid supplementation on muscle serumic damage indexes after heavy resistance exercise in wrestlers.

Materials and Method: Twenty-nine young wrestlers were randomly selected and divided into three groups. All subjects were participated in heavy resistance exercise (3 sets, 10 repetitions, 80% 1RM). The BCAA was given at doses of 210 and 450 mg/kg for supplemental groups 1 and 2 respectively, 30 minutes before and after to exercise test and dextrin was given at dose of 210 mg/kg for control group. To identify enzymes activity (IU/L), venous blood samples were obtained 30 min prior to exercise and at 24 and 48 hrs after exercise. Data were statistically analyzed using ANOVA with repeated measures and Bonfferoni post hoc test (p 0.05).

Results: Based on this study results, CPK, LDH, CPKMB activity were significantly increased (p<0.05) in all groups. CPK, LDH, CPKMB indexes having the highest activity in the control group, but there were no significant differences between all groups.

Conclusion: These results provide evidence that the use of two different dosage of BCAA could not decrease muscle damage associated with heavy resistance exercise.
