Abstract
The aim of this study was to examine the effects of a BCAA supplementation on markers of muscle damage followed eccentric exercise in basketball players. Twenty-six elite male basketball players (mean ±SD age, 29.04±3.55 years; weight, 89.54±8.98 kg; BMI, 25.43±1.44 kg.m2; body fat percentage, 14.30±3.60) volunteered to participate in the study and were selected randomly and assigned to supplement (n=13) and placebo (n=13) groups. The damaging exercise consisted eccentric exercise (15 set and 10 repetitions per set). Creatine kinase (CK), lactate dehydrogenase) LDH), maximal voluntary contraction (MVC), muscle soreness was measured immediately before the damaging exercise and at 24, 48, 72 and 96 hours’ post-exercise. Data were statistically analyzed using SPSS 18 (P<0.05). There was significant reduction in CK, LDH and muscle soreness in the BCAA group compared to the controls (P<0.05). In addition, the recovery of MVC was greater in the supplement group (P<0.05). BCAA supplement decreases eccentric exercise induced muscle damage and improves recovery in male basketball players.
