To examine habitual sleep health and investigate how habitual sleep duration impacts performance and motivation in Reserve Officers' Training Corps (ROTC) tactical athletes.
Observational.
A large, state university.
Fifty-four young tactical athletes enrolled in ROTC.
Participants wore wrist actigraph devices and completed sleep diaries for 7 days prior to completing a cognitive/motor test battery.
The mean objective total sleep time of the participants was 6.17 ± 0.69 hours, with only 7.4% of participants averaging ≥7 hours of sleep per day. A mean sleep quality rating between "Poor" and "Fair" was reported by 22.2% of participants. The mean Epworth Sleepiness Scale rating was 8.80 ± 3.24, with 27.8% of participants reporting scores >10. Controlling for age and gender, the average objective total sleep duration was significantly associated with performance on the Symbol Digit Modalities Test (P = .026) and with motivation levels to perform the cognitive/motor battery (P = .016), but not with performance on the Psychomotor Vigilance Test, Flanker task, Trail Making Test, or Standing Broad Jump.
ROTC tactical athletes habitually sleep less than the recommended 7 hours per day with roughly one-fourth reporting excessive daytime sleepiness and one-fifth reporting poor sleep quality, which may increase their risk for future adverse health outcomes. Longer sleep durations were associated with higher motivation levels and better cognitive processing speed performance; however, they were not associated with executive function, psychomotor vigilance, or broad jump performance.
研究习惯性睡眠健康，并调查习惯性睡眠时间对后备军官训练队（ROTC）战术运动员表现和动力的影响。
观察性研究。
一所大型州立大学。
54 名参加 ROTC 的年轻战术运动员。
参与者佩戴腕部活动记录仪，并在完成认知/运动测试前完成 7 天的睡眠日记。
参与者的平均客观总睡眠时间为 6.17±0.69 小时，仅有 7.4%的参与者平均每天睡眠 7 小时以上。22.2%的参与者报告睡眠质量评分为“差”到“一般”之间。平均 Epworth 嗜睡量表评分为 8.80±3.24，27.8%的参与者报告得分>10。控制年龄和性别后，平均客观总睡眠时间与符号数字模态测试的表现显著相关（P=0.026），与执行认知/运动测试的动力水平显著相关（P=0.016），但与精神运动警觉测试、Flanker 任务、连线测试或站立跳远的表现无关。
ROTC 战术运动员习惯性睡眠时间少于推荐的每天 7 小时，约四分之一报告白天过度嗜睡，五分之一报告睡眠质量差，这可能增加他们未来不良健康后果的风险。更长的睡眠时间与更高的动力水平和更好的认知处理速度表现相关；然而，它们与执行功能、精神运动警觉或跳远表现无关。
