Background: Measuring the implementation of school-based physical activity (PA) interventions is an important prerequisite in assessing their impact. Prior to conducting a study to assess the implementation of the daily physical activity (DPA) policy in Ontario, Canada, a literature review was conducted to identify existing survey instruments to…

Background: High school students have few physical education (PE) and health requirements for graduation. Twenty-first century students have choices to take their PE and health courses in the traditional face-to-face (F2F) setting or online through accredited virtual schools. The purpose of this inquiry was to examine differences in high school…

Background: Four-day school week (FDSW) use has increased substantially among US districts in recent years, but limited data exist on health impacts of this school schedule. This study examined associations of reduced school exposure via FDSWs with adolescent health and risk behaviors, obesity, and food security. Methods: Self-report data from…

Background: Schools are important venues for providing and promoting physical activity, but little is known about how school websites are being used for these purposes. Completing a content analysis of existing school websites is essential to understanding their function and value relative to supporting physical education (PE) and physical…

Background: Most youth in the United States do not meet the recommended 60 minutes of daily physical activity (PA). The school environment offers an opportunity to engage students in PA. The purpose of this study was to evaluate the impact of a comprehensive school-based physical activity program on student PA across student-level and school-level…

Background: Due to the COVID-19 pandemic, students and teachers have transitioned to online learning. The transition required changes in teaching practices to accommodate for an online learning environment. However, there are no studies characterizing physical educators' and school health experts' perspectives on physical education via distance…

Background: Adolescent girls are likely to be less active than adolescent boys. A range of factors including multiple psychosocial aspects are thought to influence their engagement in physical activity (PA). This study aimed to explore adolescent girls' perceptions and experiences of school-based PA to inform a subsequent intervention, the Girls…

Background: Moderate-to-vigorous physical activity (MVPA) declines during adolescence, particularly among girls. In this randomized control trial, we examined MVPA in a physical activity intervention compared to physical education (PE) class as usual (TAU), stratified by sex and weight classification. Standardized BMI (zBMI) overtime was also…

Background: The aims were to: (1) examine the levels of physical activity (PA) during different time periods (ie, daily PA, school hour PA, recess PA, physical education classes [PEC] PA) in children and adolescents; and (2) identify the rate of compliance with the specific PA recommendations for these time periods. Methods: The participants were…

Background: Although physical activity can play a positive role in psychosocial development, few studies have longitudinally examined the relationship between physical activity from physical education (PA from PE) and perceived peer acceptance (PPA). Methods: Data from the Korean Children and Youth Panel Survey were used with 1908 elementary…

Background: In this study, we examined the development of children's moderate to vigorous physical activity (MVPA) and physical education (PE) enjoyment through the Physical Activity as Civil Skill Program 2012-2014. Methods: Participants were 661 (265 intervention, 396 control) elementary school children in central and northeast Finland. The…

Background: This study tested the hypothesis that written district wellness policies are associated with higher rates of implementation of nutrition and physical activity practices. Methods: Written wellness policies and building level practices were assessed for schools (N = 295) within high-need districts (N = 70) in New York State. The…

Background: Significant proportions of young people experience body dissatisfaction, which has implications for psychological and physical well-being. Lesson content and perceived competence may be important variables for the experience of body dissatisfaction, yet these have been underexplored in physical education. The aim of this…

Background: The accuracy of students' heights and weights measured by school staff for body mass index (BMI) screening/reporting has not been established. This study examined school staffs' measurement accuracy, comparing accuracy by staff- and student-level characteristics. Methods: School staff and researchers measured the height and weight of…

Background: Despite increased awareness of concussions, epidemiologic surveillance efforts have been scarce, especially among adolescents. This project, which was developed with school stakeholders (certified athletic trainers [ATCs], nurses, athletic directors), piloted a public secondary school-based online surveillance tool for interscholastic…
