| Outline of Final Research Achievements |
We aimed to develop a more effective method of hypoxic training from the viewpoint of muscle energy metabolism. We investigated the muscle energy metabolism during exercise under normoxia and hypoxia. Our results suggested that during identical load exercise, aerobic energy release was lower and anaerobic energy release was higher under hypoxia than under normoxia. In the present study, we investigated the effects of high-intensity, short-duration exercise training under hypoxia on muscle energy metabolism. The results indicated that the increase in the ability of anaerobic energy release was greater after the training under hypoxia than under normoxia.
