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…

Background: Schools play a vital role in student health, and a collaborative approach may affect health factors such as physical activity (PA) and nutrition. There is a lack of recent literature synthesizing collaborative approaches in K-12 settings. We present updated evidence about interventions that used a coordinated school health approach to…

Objective: Examine effects of self-affirmation on university students' processing of health risk messages related to sedentary behavior. Participants: Eighty-eight students from a Canadian university (females = 53; males = 35; M[subscript age] = 21.74, SD = 5.36) participated during the 2018-2019 academic year. Methods: Participants were…

Exercise is necessary for healthy living, yet individuals with intellectual disability (ID) remain strikingly inactive compared with nondisabled peers. To improve this outcome, individuals with ID can exercise independently by self-instructing. Self-instruction is considered a pivotal skill once it generalizes to untrained stimuli. This study used…

Lifestyle risk behaviours--physical inactivity, poor diet, poor sleep, recreational screen time, and alcohol and tobacco use--collectively known as the "Big 6" emerge during adolescence and significantly contribute to chronic disease development into adulthood. To address this issue, the Health4Life program targeted the Big 6 risk…

Objective: This study examined the unique and interactive effects of PA volume and within-person fluctuations in PA volume (i.e., intraindividual variability in PA volume; PA-var) on preschoolers' (N = 141; 47.5% girls) ADHD symptoms. Method: Preschoolers wore accelerometers during the school day over a 2-week period. Teachers reported on…

Background: School-based health education can provide students with learning experiences that improve knowledge, attitudes, and perceptions (KAP) and behaviors regarding physical activity and nutrition. Methods: We conducted a 2-phase systematic review. Phase 1 was a review of reviews (ie, systematic reviews or meta-analyses) that were published…

Background: Adopting healthy weight-related behaviours in emerging adulthood has long-term health benefits. Digital interventions using game-elements have the potential to improve diet and physical activity outcomes. Universities are influential settings in shifting emerging adults' behaviour and can deliver health-promoting interventions to young…

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…

Objective: To examine the relationship between self-reported health, BMI, diet, and physical activity among students at three diverse institutions of higher learning (private university, HBCU, and community college), and investigate similarities and differences in behaviors and outcomes at these schools and how targeted interventions might support…

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…

Poor physical development in young children has been shown to impact readiness for school, behaviour, social development and academic achievement. This research sought to explore whether a physical intervention programme (Movement for Learning) can improve children's physical development. The Movement Assessment Battery for Children (2nd edition,…

Background: Physically active lessons have not often been assessed with randomized controlled trials. Aims: Evaluate the effects of the "Virtual Traveller" (VT) intervention delivered using classroom interactive whiteboards on physical activity, on-task behavior, and student engagement. Methods: Participants were 219 children aged 8 to 9…

Objectives: Many school-aged children do not meet the daily minimum recommendations for accruing moderate to vigorous physical activity (MVPA), and spend much of their day sedentary. The purpose of this study was to investigate the effects of teacher-delivered classroom-based physical activity (CBPA) on students' MVPA and sedentary behaviors.…

Background: We examined longitudinal changes in children's physical activity during the school day, afterschool, and evening across fifth, sixth, and seventh grades. Methods: The analytical sample included children who had valid accelerometer data in fifth grade and at least one other time-point, and provided complete sociodemographic information…
