Abstract
- Adequate sleep is crucial for elite athletes' recovery, performance readiness, and immune response. Establishing reference ranges for elite athletes enables appropriate contextualization for designing and targeting sleep interventions. Purpose: To establish sleep-quality reference ranges for Olympic and Paralympic cohorts using the Pittsburgh Sleep Quality Index (PSQI) and explore differences based on sex and sport types. Methods: Team USA athletes (men = 805, women = 798) completed the PSQI as part of a health-history questionnaire. Descriptive statistics were used to create reference ranges and linear models, and χ<superscript>2</superscript> test of independence determined differences in PSQI global and component scores between sex, games, season, and participation. Results: Six hundred thirty-two (39.43%) athletes reported poor sleep (PSQI<subscript>Global</subscript> ≥ 5). Men displayed later bedtimes (P =.006), better global PSQI scores, shorter sleep latency, less sleep disturbance, and less use of sleep medication than women (all P <.001). Winter Games participants had later bedtime (P =.036) and sleep offset time (P =.028) compared with Summer Games athletes. Team-sport athletes woke earlier than individual-sport athletes (P <.001). Individual-sport athletes were more likely to have low (P =.005) and mild (P =.045) risk for reduced sleep duration than team-sport athletes. Conclusion: These data provide PSQI-specific reference ranges to identify groups at greatest risk for poor sleep, who may benefit most from targeted sleep interventions. [ABSTRACT FROM AUTHOR]
