Differences in Sitting Time by Club Sports Participation among Austrian Youth

Abstract

Despite the well-documented detrimental health effects of prolonged engagement in sedentary behaviors, children and adolescents spent a large amount of time with seated activities. The present study examined the association between participation in club sports and various sedentary behaviors during weekdays and the weekend in youth between 11 and 17 years of age. A total of 1225 (50.1% male) adolescents completed a validated questionnaire that examined sitting time in activities related to work as well as during leisure time such as screen use, reading, and listening to music in addition to sleep time. Participants spent an average of 12.7 ± 1.7 and 9.9 ± 2.0 h/day during weekdays and the weekend, respectively, in seated behaviors while they were awake. Club sports participants reported less time spent sitting (p < 0.01), which was mainly attributed to recreational activities (e.g., screen use, reading, listening to music). Sleep time during weekdays, on the other hand, was higher in club sports participants. Sex-specific results further showed that differences by club sports participation were more pronounced in girls compared to boys. Despite the potential beneficial effects of club sports participation, additional efforts are needed to reduce sitting time in adolescents as either group spent the majority of their time awake with sedentary behaviors.
