Abstract
Consumption and restoration of muscle glycogen and changes in anabolic and catabolic steroid hormones were analyzed in five male elite orienteers during and after an orienteering competition. The magnitude of glycogen consumption and pronounced increase in serum-cortisol during the orienteering race reflect the great muscular output demands during forest running. The free testosterone/cortisol ratio was normalized to the initial level within four hours post-exercise. Synchronously, only 25 of the muscle glycogen loss was restored. Within 24 hours post-exercise all runners showed normalized levels of testosterone, cortisol and free testosterone/cortisol ratio. The glycogen content was also restored except in one of the runners. We concluded that daily orienteering competitions per se do not seem to create risks for developing a state of hormonal imbalance or significantly decrease in glycogen when the carbohydrate supply is appropriate.
