目的
睡眠剥夺（SD）在超耐力比赛中非常常见。目前，咖啡因和小睡等兴奋剂是减少SD对超耐力表现的负面影响的主要策略。在这个案例研究中，作者描述了一种新策略的应用，该策略包括在超耐力比赛前几周间歇性重复SD（SD训练[SDT]）。
方法
一名男子超耐力跑运动员在参加为期6天的比赛之前，除了常规的体能训练计划外，还接受了为期6周的SDT计划（包括每周日1晚的SD）。在SDT之前和之后，参与者在第一和第三个晚上进行连续5天的每天2小时的SD恒速跑步。在这个多日的测试中，测量了心理和生理反应。
结果
运动员对SDT耐受良好。对数据的视觉分析表明，在超耐力比赛前几周进行SDT可能对连续5天长时间跑步和2晚SD的情况下的嗜睡和感知精神努力产生有益影响。这种多日测试似乎是在实验室评估超耐力运动员的可行方法。
结论
这些结果提供了一些关于SDT的令人鼓舞的初步信息，这些信息需要在一组超耐力运动员的随机对照试验中得到证实。如果被证实是有效的和良好的耐受性，SDT可能会在未来用于帮助超耐力运动员和其他人群，必须在SD的条件下进行。
PURPOSE
Sleep deprivation (SD) is very common during ultraendurance competitions. At present, stimulants such as caffeine and naps are the main strategies used to reduce the negative effects of SD on ultraendurance performance. In this case study, the authors describe the application of a novel strategy consisting of the intermittent repetition of SD (SD training [SDT]) during the weeks preceding an ultraendurance competition.
METHODS
A male ultraendurance runner underwent a 6-week SDT program (consisting of 1 night SD every Sunday) in addition to his regular physical training program before taking part in a 6-day race. Before and after SDT, the participant performed 5 consecutive days of daily 2-hour constant-pace running with SD on the first and third night. Psychological and physiological responses were measured during this multiday test.
RESULTS
SDT was well tolerated by the athlete. A visual analysis of the data suggests that including SDT in the weeks preceding an ultraendurance competition may have beneficial effects on sleepiness and perceived mental effort in the context of 5 consecutive days of prolonged running and 2 nights of SD. This multiday test seems a feasible way for assessing ultraendurance athletes in the laboratory.
CONCLUSIONS
The results provided some encouraging initial information about SDT that needs to be confirmed in a randomized controlled trial in a group of ultraendurance athletes. If confirmed to be effective and well tolerated, SDT might be used in the future to help ultraendurance athletes and other populations that have to perform in conditions of SD.
