ABSTRACT

OBJECTIVE To examine habitual sleep health and investigate how habitual sleep duration impacts performance and motivation in Reserve Officers' Training Corps (ROTC) tactical athletes. DESIGN Observational. SETTING A large, state university. PARTICIPANTS Fifty-four young tactical athletes enrolled in ROTC. MEASUREMENTS Participants wore wrist actigraph devices and completed sleep diaries for 7 days prior to completing a cognitive/motor test battery. RESULTS 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. CONCLUSIONS 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.
