Biochemical status, oxidative and antioxidant responses after 3-month specific training in elite karate athletes

摘要

Aim: To investigate the effects of 3-month-long specific training program on biochemical status, oxidative and antioxidant responses in elite karatekas. Methods: Twenty male karatekas [BMI: 21.9 +/- 2.4 (kg/m(2))] participated in this study. They performed a 3-month specific training to prepare for an international competition. We measured selected biochemical parameters, the oxidative and antioxidant responses before (T0) and after 3 months of intense karate training (T1). Results: We found significant increases in catalase activity (26.3% +/- 21.3%, p 0.0005), superoxide dismutase activity (15.9% +/- 28.8%, p 0.05), and a significant decrease in malondialdehyde levels (17.2% +/- 13.7%, p 0.0005) after 3 months of karate training. Moreover, the athletes' biochemical status was significantly improved at T1 compared with T0 (for the majority of parameters, p 0.0005). Conclusions: The specific training program improves the prooxidant-antioxidant balance of elite karate athletes. It could be recommended for athletes having similar physical fitness level.
