Outline of Final Research Achievements |
To clarify the prevalence of poor sleep quality and its associated factors among elite Japanese athletes, the questionnaire study was conducted. Twenty-eight percent of the athletes were classified as poor sleepers. Their poor sleep quality was associated with five factors. To examine a simple evaluating system of the sleep under hypoxia, we compared among the data from polysomnography, actigraphy, sheet-sensor, and peripheral-artery-tonometry. Though the convenience that peripheral-artery-tonometry can pick up respiratory disturbances under hypoxia, sleep/wake identification from the actigraph and the sheet-sensor were similar from the polysomnograph. To evaluate the effects of pre-flight circadian phase-shifting approach on sleep after eastward transition, two athletes gradually advanced their sleep–wake schedules, took ramelteon 5.5 h before their bedtimes, and were exposed to bright light in the early morning. The approach improved their sleep in the destination areas.
