Poor sleep quality and insufficient sleep of a collegiate student-athlete population

Objective: Poor and inadequate sleep negatively impact cognitive and physical functioning and may also affect sports performance. The study aimis to examine sleep quality, sleep duration, and daytime sleepiness in collegiate student-athletes across a wide range of sports. Design: Questionnaire. Setting: University setting. Participants: 628 athletes across 29 varsity teams at Stanford University. Measurements: Athletes completed a questionnaire inquiring about sleep quality via a modified Pittsburgh Sleep Quality Index (PSQI), sleep duration, and daytime sleepiness via Epworth Sleepiness Scale. Sleep quality on campus and while traveling for competition was rated on a 10-point scale. Results: Collegiate athletes were classified as poor sleepers (PSQI 5.38 +/- 2.45), and 42.4% of athletes experience poor sleep quality (reporting PSQI global scores >5). Athletes reported lower sleep quality on campus than when traveling for competition (7.1 vs 7.6, P<.001). Inadequate sleep was demonstrated by 39.1% of athletes that regularly obtain <7 hours of sleep on weekdays. Fifty-one percent of athletes reported high levels of daytime sleepiness with Epworth scores >= 10. Teen student-athletes in the first and second year of college reported the highest mean levels of daytime sleepiness. Greater total sleep time was associated with daytime functioning including lower frequency of difficulty waking up for practice or class (P<.001) and lower frequency of trouble staying awake during daily activities (P<.001). Conclusions: Collegiate athletes frequently experience poor sleep quality, regularly obtain insufficient sleep, and commonly exhibit daytime sleepiness. (c) 2018 National Sleep Foundation.
