摘要：Physical activity has been shown to have many health benefits for youth, including improved cardiovascular health, blood pressure, body composition, strength and endurance, aspects of mental health, and academic performance. (1,2) The Canadian Society for Exercise Physiology (CSEP) published evidence-based, physical activity guidelines in 2011. (3) The guidelines recommend that youth need to achieve a minimum of 60 minutes of moderate to vigorous physical activity (MVPA) each day to achieve health benefits, where MPVA is defined as 3-6 metabolic equivalents (METS) and vigorous physical activity (VPA) is defined as over 6 METS. (3) The guidelines also recommend that youth should participate in both resistance training (RT) and VPA at least three days per week. However, the available evidence suggests that most Canadian youth are not active enough to achieve the health benefits associated with being physically active. (4)

The physical and built environment surrounding youth can have an important impact on physical activity levels. (5,6) Research has also identified that self-reported physical activity levels can vary significantly (~3%-8%) across secondary schools in Canada. (7,8) Although this variation is modest, research has identified that characteristics of the physical environment at a school (e.g., facilities for physical activity) help to explain some of the variation in overall physical activity among students across schools. (7-12) For instance, having an extra room available for physical activity has been associated with higher activity levels among youth. (8) Considering the limited research examining how different school contexts are associated with student activity levels, additional investigation of this issue seems warranted.
