Physical activity (PA) and exercise are a crucial component for improving and maintaining physical and psychological health outcomes. However, recent research has demonstrated a lack of exercise engagement and an increase in sedentary behaviour worldwide posing as a health risk. Hence, a greater understanding of factors that increase PA and exercise is paramount. It has been shown in prior research that sleep behaviours including chronotype may influence PA engagement (Kauderer & Randler, 2013; Kline, 2014; Tang & Sanborn, 2014). The current study examined whether sleep quality and morningness chronotype predicted individuals’ PA and exercise engagement after controlling for confounding variables (age, gender, physical occupation and conscientiousness). 122 adults (males: 29.5%, females: 70.5%) with a mean age of 33.25 (SD= 13.13) were recruited on two social media websites (Facebook and Instagram). All participants completed the study questionnaire which included the International Physical Activity Questionnaire-short form, Pittsburgh Sleep Quality Index, Composite Scale of Morningness and the conscientiousness subscale of the Big Five Inventory, respectively. A hierarchical multiple regression analysis found sleep quality and morningness chronotype did not predict physical activity and exercise engagement. Physical occupation was the only significant predictor of PA (β = .40, p = < .001). The variance of the overall model was 18.9%. Based on the current cross-sectional study better sleep quality and morningness chronotype may not increase PA and exercise engagement.
