Effects of a five-minute classroom-based physical activity on on-task behavior and physical activity levels

Purpose: Opportunities for physical activity during the school day are steadily declining. Simultaneously, more time is allocated for improving pupils’ academic achievements. Study aims to explore the effectiveness of a five- minute classroom-based physical activity (5min- Class-PA) to keep student behavior on task while increasing physical activity and energy expenditure during school days. Methods: A sample of 126 elementary school pupils (6-10- year-old) was selected to participated in a 5- min PA daily in the middle of a 45-min academic lesson by imitating video animations (Brain Break by HOPSports®). Multiple baselines across subjects design was implemented for 12 weeks to assess on-task behavior during academic lessons by observing pupils in a classroom. A quasi- experimental design was implemented for 8 weeks to assess PA volume and energy expenditure using SenseWear Armband body monitor (BodyMedia Inc., Pittsburgh, PA, USA). Results: When 5min- Class-PA was implemented, initially high on- task behavior during the first part of the lesson (91.42% and 94.8% for 6-8 and 8-10-year- old pupils, respectively) was not significantly changed after the 5min-Class- PA. In contrast, when 5min-Class-PA was not implemented, on-task behavior during the second part of the lesson decreased (by 3% and 4% for 6-8- and 8-10-year- old pupils, respectively). Additionally, after the 5min-Class-PA was systematically introduced, on-task behavior systematically improved. The results also indicate there is a significant increase or improvement in PA levels and energy expenditure during school days. Conclusion: On-task behavior during academic lessons and daily in-school PA levels can be improved by implementing a 5min-Class- PA.
