Background: Adolescent sport participation brings many benefits, but can negatively influence aspects of health that are especially vulnerable during this developmental stage. Sleep health impacts both performance anxiety and mental burnout, which are directly related to the demands of daily practices, competitions, and overall athletic performance. 

Purpose: To analyze device-measured sleep health metrics and their relation to levels of performance anxiety and mental burnout in adolescent student athletes. 

Methods: Participants included middle and high school student athletes ages 11 to 18 participating in at least one competitive sport season, including clubs or teams outside of school. Students completed a questionnaire assessing anxiety and burnout symptoms. Additionally, to estimate activity and sleep metrics, students wore an activity monitor on their non-dominant wrist and completed a log for one week. 

Results: Summary statistics will be calculated for each sleep health variable. Multiple regression models will be run, with performance anxiety as the outcome and each sleep health metric as an independent variable. A second set of linear regression models will be run with mental burnout as the outcome and each sleep health metric as an independent variable. We predict that poor sleep health metrics will be associated with higher levels of performance anxiety and mental burnout in adolescent student athletes.
