INTRODUCTION: This study was performed to investigate the biochemical changes related to muscle and cartilage damage and cytokine secretion during ski jump.
METHOD: Seven well trained ski jumpers were participated in the present study. Blood samples were obtained from subjects who were participated in before training, ski jump training (jump for seven), ski jump training (jump for fourteen), and recovery day 1-day 3.
RESULTS: Serum COMP was increased during a jump and declined to the pre level after 2 days recovery. The CPK and hs-CRP level of during exercise wereunchanged and declined to the pre level after 2 days of recovery. Therefore, high frequency jumping may induce more stress both on muscle and cartilage. Further, the required time for recovery may vary with jumping volume and the tissue type, e.g. cartilage or skeletal muscle as in this case.
CONCLUSION: These results showed that, in ski jumping, it takes two days for an athlete to completely recover from the jump training session. Hence, training on a day’s interval may be possible, but consecutive training may have a devastating effect on the muscles and joints.
