Background: We aimed to characterize relationships between delayed high school start time policy, which is known to lengthen school night sleep duration, and patterns in activity outcomes: physical activity, non-school electronic screen time (non-schoolwork), and sports and extracurricular activity among adolescents. Methods: We used data from the…

School-based physical activity (PA) interventions stand out as a highly valued knowledge technology in relation to attempts to promote daily physical activity (DPA) among school youth. The purpose of the paper is to explore technologies of knowledge that guide school-based PA interventions in lower secondary schools and discuss their power-related…

A renovation incorporated Innovative Learning Environments' design principles. The exploratory study used a Basic Mixed Method, Convergent Parallel Research Design. Behavioral observations and photographic tracing, two surveys (pre- and post-intervention), interviews, and instrument testing. Overall findings: (a) students and educators are excited…

Many children with disabilities engage in less physical activity compared to their peers. This pilot-feasibility study examines the effects of movement-based desk and alternative seating on classroom physical activity, time on task, reading fluency, and reading comprehension scores in fourth/fifth and seventh/eighth-grade children with…

This study examined moderate-to-vigorous physical activity (MVPA) trends in physical education (PE) classes and beyond school hours in children's need satisfaction profiles over 3 years. Participants were 445 (girls 256, boys 189) Finnish schoolchildren (M[subscript age] = 11.26 ± 0.32 years). Need satisfaction self-reports and accelerometer-based…

Despite well-established benefits, the majority of young people around the globe are not sufficiently active. In many countries, including Australia, physical activity (i.e. physical education and school sport) is not mandatory in the final two years of high school (i.e. senior school years). The aim of this study was to assess the impact of a…

Many university students are insufficiently physically active to the detriment of their physical and mental health. University students' physical activity motives are important for understanding students' physical activity levels and patterns, and for offering insight into how students' physical activity, and health, could be enhanced. The purpose…

This study aimed to capture the multidimensionality of adolescents' motivation in the physical education (PE) setting, within self-determination theory, by employing self-organizing maps (SOM) analysis. Particularly, it examined the topological relationships among students' basic psychological needs satisfaction, their perception of more or less…

Recent literature draws attention to the fact that problematic Internet use is a growing health issue among adolescents worldwide. This study aimed to find the potential demographic, physical and psychopathological risk factors associated with severe problematic Internet use of adolescents. A total of 1,347 adolescents (45.1% males) were recruited…

Background: The adoption of a shortened school week from the traditional 5 to 4 days is increasing nationwide. Budgetary and staffing needs are driving the change, yet research on the effects on students is lacking, especially regarding student health. Our study examined student health in 4 vs 5-day schools in Colorado, a state with one of the…

This study addresses the issue of insufficient physical activity (PA) among youths. The emergence of gamified interventions, such as Gamifiter web portal, offers a novel approach to promoting healthy habits and increasing intrinsic motivation for PA. Gamifiter engages users in virtual challenges linked to daily step counts and progress on a…

Background: Approximately 8.8% of US high school students attended private schools in 2015. Few studies have characterized health risk behaviors among these students or compared prevalence of behaviors between students in private and public schools using a contemporary, nationally representative sample. Methods: Pooled 2007-2017 national Youth…

Objective: To explore young people's perceptions of pedometers and investigate behaviours exhibited while being monitored. Design: Qualitative design using six focus groups with participants (mean age 14.7 years). Setting: Study participants (n = 24) were randomly selected from a previous study of 123 young people aged 14-15 years from three…

The decline in physical activity (PA) from youth to young adulthood is evident, though limited research has addressed whether specific factors of K-12 physical education (PE) have any influence on outcomes during college years. This study examined the relationship between college students' physical fitness and PA behavior and their high school PE…

Background: Children from disadvantaged backgrounds are more apt to experience lower availability of nutritious foods, lack opportunities to exercise, and lack access to recreational facilities, and thus, are more likely to be obese and at greater risk for developing chronic diseases. We review school health education programs' impact on physical…
