| Outline of Final Research Achievements |
Although high altitude training provides a great training effect, the reduction in the partial pressor of arterial carbon dioxide induced by hyperventilation will cause central apnea, an increase in arousal and a decrease in the duration of slow-wave sleep during sleep, which may deteriorate sleep quality. In this study, we examined whether a high carbon dioxide concentration in nomobaric hypoxia room (15.4 % O2) affects the quality of sleep.
As a result, the carbon dioxide concentration of 1500 ppm in normobaric hypoxia room did not affect sleep structure, respiratory events, autonomic function and SpO2 compared to low oxygen-only environment (15.4 % O2). The result of this research is a result at 1,500 ppm of carbon dioxide, and it is necessary to investigate using higher carbon dioxide concentration to clarify the role of carbon dioxide in sleep quality at high altitude.
