ABSTRACT
Background: Studies reported small proportions of moderate-to-vigorous physical activity (MVPA) in physical education (PE) classes conducted with children, but there is little information regarding PE class characteristics that might affect a lack of intense PA.
Objective: To compare the intensity of PE classes with different contextual characteristics.
Methods: Twelve PE classes of children from 2nd to 5th grades (7 to 11-year-olds) were observed. Contexts were classified as Management, Game Play, Free Play, Fitness, and Skill Practice. Children wore accelerometers and MVPA was estimated. The proportion of time on each context and MVPA of each PE class was analyzed.
Results: Game Play was the most observed context, and Management was observed in all classes, but with smaller proportions. Fitness was not observed, while Free Play and Skill Practice were rarely observed. Children spent 25% or less of PE class time in MVPA, and accumulated more MVPA in classes where Game Play was predominant.
Conclusion: A quarter or less of PE class time had MVPA. Game Play was the most frequent and intense context. Implementing more fitness and skill practice could increase PE classes intensity and expand childrens motor experiences. Reducing time in Management could also benefit childrens participation in MVPA.
