Material and methods: Polysomnographic (PSG) data was continuously recorded (total sleep time and sleep stage distribution) in a 34-year-old male whilst performing the new world record in long-term downhill skiing. He napped only during the short ski lift rides for 11 days and nights. Results: After an initial period of complete sleep deprivation for 24 hours, total sleep time and the total times of non-REM and REM achieved during the lift rides returned to standard values on the second day. PSG data revealed an average sleep time per 24 hours of 6 hours and 6 minutes. During daylight sleep was rarely registered. The subject experienced only two minor falls without injury and immediately resumed skiing. Conclusion: In a healthy, trained, elite male athlete, sleep fragmentation over 11 consecutive days did not significantly impair the sleep, motor or cognitive skills required\u0000to perform a continuous downhill skiing world record after an initial adaptation phase.\u0000\u0000","PeriodicalId":419847,"journal":{"name":"Health Promotion & Physical Activity","volume":"47 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123521717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
