Abstract

The study was conducted to determine the effect of orange juice on muscle damage and leucocytes count of Tarung Derajat Athletes. Subjects were 10 athletes of Tarung Derajat, divided two group: orange juice (OJ) and placebo (PLA), quasi experiment study. Participant were randomized to consume 300 ml OJ or 300 ml PLA and exercise of Tarung Derajat for 12 d. Blood sample were obtained at baseline and 48 post-intervention. Measurement of muscle damage (creatine kinase/CK) and leucocytes count. OJ consumption was no effect on CK level (p=0,296 > 0,05) and significantly correlated on leucocytes count (p=0,005 < 0,05). OJ have effect on exercise-induced decreases leucocytes count, but no effect on muscle damage.
