In solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors' performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races. Twelve men (professional sailors) recorded their sleep and measured their response times during one of the three single-handed races of 150, 300 and 350 nautical miles (nominally 24-50 h in duration). Total estimated sleep duration at sea indicated considerable sleep insufficiency. Response times were slower after races than before. The results suggest that professional sailors incur severe sleep loss and demonstrate marked performance impairment when competing in one- to two-day solo sailing races. Competitive performance could be improved by actively managing sleep during solo offshore sailing races.
在像单人不间断跨大西洋帆船赛这样的单人离岸帆船比赛中，必须通过多次短时间睡眠来维持竞技表现和安全。对于海上经历的睡眠限制量以及睡眠不足导致的疲劳对水手表现的影响，人们了解甚少。因此，我们评估了费加罗2博纳多级帆船赛中赛艇上水手的睡眠情况，并比较了比赛前后连续简单反应时间测试中的反应时间。12名男性（职业水手）在150、300和350海里（名义时长24 - 50小时）的三场单人比赛中的一场记录了他们的睡眠并测量了反应时间。海上估计的总睡眠时间表明睡眠严重不足。比赛后的反应时间比之前更慢。结果表明，职业水手在参加一到两天的单人帆船比赛时会遭受严重的睡眠不足，并表现出明显的表现受损。在单人离岸帆船比赛中积极管理睡眠可以提高竞技表现。
