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

Material and Methods 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.

Results 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.

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