The present study evaluates the effects of pre-race sleep and training characteristics among ultra-athletes and support crew, and the influence of these factors on the athlete's performance in a 217-km ultramarathon. A total of 38 ultramarathon runners and 59 support crew members were assessed. The participants answered questionnaires about chronotype, sleep quality, sleepiness, basic demographics, and pre-race training. The clinical trial registration number is RBR-7j6d23v. The results showed that athletes and support crew had a morning-type chronotype and good sleep efficiency; most had poor-quality sleep. The athletes who finished the race had a higher sleep latency than non-finishers (p < 0.001). The quality of sleep may have impacted performance because the athletes with good sleep quality trained one day more per week than those without (p < 0.001), and training frequency was highly correlated with the race time (r = -0.59). These findings are novel, expand the data about sleep, training, and performance in an ultramarathon, and innovate by addressing the support crew.
本研究评估了超长距离运动员和支援人员赛前睡眠和训练特点的影响，以及这些因素对运动员在 217 公里超长距离马拉松比赛中表现的影响。共有 38 名超长距离马拉松运动员和 59 名支援人员接受了评估。参与者回答了关于昼夜类型、睡眠质量、嗜睡、基本人口统计学和赛前训练的问卷。临床试验注册号为 RBR-7j6d23v。结果表明，运动员和支援人员的昼夜类型为晨型，且睡眠效率良好；大多数人的睡眠质量较差。完赛运动员的睡眠潜伏期高于未完赛运动员（p<0.001）。睡眠质量可能会影响表现，因为睡眠质量好的运动员比睡眠质量差的运动员每周多训练一天（p<0.001），且训练频率与比赛时间高度相关（r=-0.59）。这些发现是新颖的，扩展了关于超长距离马拉松比赛中睡眠、训练和表现的数据，并通过关注支援人员进行了创新。
