Fiber type distributions of the fast-twitch extensor digitorum longus muscle in rats were examined after exposure to hypobaric-hypoxia for 5 weeks from the postnatal age of 5 weeks or for 10 weeks from the postnatal age of 10 weeks. Muscle fibers were classified into fast-twitch oxidative glycolytic (FOG), fast-twitch glycolytic (FG), or slow-twitch oxidative (SO). The percentage of FOG fibers was increased and that of FG fibers was decreased in the hypoxic rats at 10 weeks of age, while there was no difference in the percentage of SO fibers between the normoxic and hypoxic rats. There was no difference in the fiber type distribution between the normoxic and hypoxic rats at 20 weeks of age. These results indicate an age-specific response of hypobarichypoxia on the fiber types of the rat extensor digitorum longus muscle.
