| Research Abstract |
The purpose of this study was to clarify the effect of Living high-training low on physiological adaptations and exercise performance at sealevel. Hypoxic condition was normobaric hypoxia. The results from animal study showed that (1) a normobaric hypoxia condition increased RBC, (2) the normobaric hypoxia condition might cause an increase of glycolitic enzymes activity, especially in fast type muscles and the effects would disappear quickly, (3) high intensity interval training under a normobaric hypoxia condition might enhance an aerobic metabolic capacity. The results from human study showed that (1) LH-TL for 10-14 days under normobaric hypoxia stimulated erythropoiesis but it was not enough to increase RBC and HG. The LH-TL enhance would an endurance performance for a submaximal test and it might be good as an endurance training. (2) Intermittent exposure to the normobaric hypoxic condition decreased plasm glutamin concentration of endurance athletes quickly. But it would recover with in a week and then dropped again.
