Outline of collaborative research

The present project focuses on the effect of newly developed lifestyle using hypoxic environment on health promotion. Although the use of “hypoxia” has been prevalent to improve exercise capacity in athletes, the utilization of hypoxia on health promotion has not been sufficiently applied. We conducted several experiments to address the impact of hypoxia during moderate intensity exercise on 24h of interstitial glucose levels. Also, since sleep quality is closely associated with the risk of physical and mental health (well-being), we determined the effect of various types of exercise in hypoxia on sleep quality. In the first experiment, we found that endurance exercise in hypoxia did not affect 24 h of interstitial glucose levels. Moreover, endurance exercise in hypoxia did not alter sleep quality (evaluated by electroencephalography). However, evening high-intensity exercise in hypoxia presented potentially negative impact on sleep. We further advanced the project to determine the effects of endurance exercise in hypoxia or passive exposure to hypoxia on vascular endothelial function, and several experiments are currently ongoing.
