This\nstudy demonstrates differential effects of partial sleep deprivation\n(SD) on sleep architecture and psychomotor vigilance task (PVT)\nperformance using two different protocols (sequentially) that\neach restricted daily sleep to 3 hours in healthy adult men. The\nprotocols differed only in the period of sleep restriction; in one,\nsleep was restricted to a 3-hour block from 12:00 AM to 3:00 AM,\nand in the other, sleep was restricted to a block from 3:00 AM to\n6:00 AM. Subjects in the earlier sleep restriction period showed a\nsignificantly lower percentage of rapid-eye-movement (REM)\nsleep after 4 days (17.0 vs. 25.7 %) and a longer latency to the\nonset of REM sleep (L-REM) after 1 day (78.8 vs. 45.5 min) than\nthey did in the later sleep restriction period. Reaction times on\nPVT performance were also better (i.e. shorter) in the earlier SR\nperiod on day 4 (249.8 vs. 272 ms). These data support the view\nthat earlier-night sleep may be more beneficial for daytime\nvigilance than later-night sleep. The study also showed that\ncumulative declines in daytime vigilance resulted from loss of\ntotal sleep time, rather than from specific stages, and\nunderscored the reversibility of SR effects with greater amounts\nof sleep.<\/jats:p>","DOI":"10.33549\/physiolres.931895","type":"journal-article","created":{"date-parts":[[2021,2,5]],"date-time":"2021-02-05T13:41:35Z","timestamp":1612532495000},"page":"821-829","source":"Crossref","is-referenced-by-count":21,"title":["Effects of different sleep restriction protocols on sleep architecture and daytime vigilance in healthy men"],"prefix":"10.33549","author":[{"given":"H","family":"Wu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"WS","family":"Stone","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"X","family":"Hsi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Zhuang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y","family":"Yin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Z","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"19169","published-online":{"date-parts":[[2010]]},"container-title":["Physiological Research"],"original-title":[],"language":"en","deposited":{"date-parts":[[2021,2,5]],"date-time":"2021-02-05T13:41:36Z","timestamp":1612532496000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.biomed.cas.cz\/physiolres\/pdf\/59\/59_821.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":0,"URL":"https:\/\/doi.org\/10.33549\/physiolres.931895","relation":{},"ISSN":["1802-9973","0862-8408"],"issn-type":[{"value":"1802-9973","type":"electronic"},{"value":"0862-8408","type":"print"}],"subject":[],"published":{"date-parts":[[2010]]}}}
