Self-reported chronotype and objective sleep timing in university student athletes and non-athletes

The aim of this paper was to test how sport participation and chronotype affect objectively measured sleep timing parameters on workdays.

The sample included 82 student athletes and 40 non-athletes who completed three-day wrist actigraphy monitoring and the Polish version of the Morningness-Eveningness Questionnaire.

Eveningness predicted later timing of falling asleep and mid-sleep, but not the wake-up time. Student athletes had earlier wake-up time and shorter sleep duration than non-athletes.

The results support the view that university students suffer insufficient sleep, especially those participating in extensive sport activity.
