This study examined sex differences among endurance athletes in pre-race relationships between sleep, and perceived stress and recovery. Thirty-six athletes completed the Short Recovery and Stress Scale, and had sleep monitored via actigraphy, over four consecutive days prior to an ultra-marathon. Overall, compared with males, females had shorter wake after sleep onset (mean ± SD, 50 ± 23 vs 65 ± 23 min, = .04) and lower (3.9 ± 1.1 vs 4.8 ± 1.1 arbitrary units, = .001). The day before the race, females scored higher for all stress-related items ( < 0.05). Among females, higher scores for (β = -31 min, = .01) and (β = -21 min, < .001) were associated with reduced sleep duration. Among males, higher scores for were associated with increased sleep duration (β = 22 min, = .01). Across all athletes, longer sleep duration was associated with improved (β = 0.003 arbitrary units, = .02). Females experienced greater pre-race stress than males, and their sleep duration was associated with emotional factors. The SRSS may help identify female athletes at risk of sleep difficulties prior to competition.
这项研究调查了耐力运动员在赛前睡眠、感知压力和恢复之间的关系中的性别差异。36 名运动员在参加超马拉松比赛前连续四天完成了短恢复和压力量表，并通过活动记录仪监测睡眠。总的来说，与男性相比，女性的睡眠潜伏期（醒来后入睡的时间）更短（平均值 ± 标准差，50 ± 23 分钟比 65 ± 23 分钟， =.04）， 更低（3.9 ± 1.1 比 4.8 ± 1.1 任意单位， =.001）。比赛前一天，女性在所有与压力相关的项目上的得分都更高（ <.05）。在女性中， 得分越高（β = -31 分钟， =.01）和 得分越高（β = -21 分钟， <.001）与睡眠时间减少有关。在男性中， 得分越高与睡眠时间增加有关（β = 22 分钟， =.01）。在所有运动员中，睡眠时间越长， 得分越高（β = 0.003 任意单位， =.02）。女性在赛前经历了更大的压力，她们的睡眠时间与情绪因素有关。SRSS 可能有助于识别比赛前有睡眠困难风险的女性运动员。
