Background: Children's executive functions develop rapidly during the preschool years and are critical for attending to lessons and meeting classroom expectations. Engaging in periods of outdoor play that have lower regulatory requirements and that provide opportunities for physical activity may help children maintain control over their behavior when they are back in settings with higher regulatory requirements. However, little work has formally examined this proposition in early childhood.

Health guidelines suggest that caregivers provide preschoolers with opportunities to be physically active for 3 h per day (roughly 15 min per waking hour), but because children are not continuously active, it is unclear what amount of time is needed to reach this goal. This naturalistic study enrolled 67 children ( = 4.5 years, 46% female) who wore accelerometers to measure their activity during indoor and outdoor free -play ( = 315,061 s).

Children's abilities to regulate their behaviors are critical for learning and development, yet researchers lack an objective, precise method for assessing children's behavioral regulation in their everyday environments such as their classrooms. This study tested a sensor-based approach to assess preschool children's behavioral regulation objectively, precisely, and naturalistically. Children wore accelerometer devices as they engaged in center-based play in their preschool classrooms for roughly 45 min (N = 50 children, 48% female, mean age = 4.

Physical activity (PA) is a health-protective factor with multiple benefits for school-age children, yet only 22% of children and adolescents living in the United States (United States) accrue the recommended amount of moderate to vigorous PA. Given the prevalence of insufficient PA among children, promoting and providing PA opportunities during the school day, especially when integrated into the curriculum and linked to the learning standards, is essential for children. The purpose of this paper is to describe the procedure for the development of a school-based PA program using an integrated approach through the modified intervention mapping protocol (IMP).

Article Synopsis
  • * In a study of children participating in an after-school physical activity program, greater baseline brain network modularity was linked to increased decreases in cortical thickness in certain brain areas.
  • * These changes in cortical thickness corresponded with enhancements in cognitive efficiency, but similar relationships were not observed in children who were wait-listed for the intervention.

Background: As mobile technologies become ever more sensor-rich, portable, and ubiquitous, data captured by smart devices are lending rich insights into users' daily lives with unprecedented comprehensiveness and ecological validity. A number of human-subject studies have been conducted to examine the use of mobile sensing to uncover individual behavioral patterns and health outcomes, yet minimal attention has been placed on measuring living environments together with other human-centered sensing data. Moreover, the participant sample size in most existing studies falls well below a few hundred, leaving questions open about the reliability of findings on the relations between mobile sensing signals and human outcomes.

Dual-task research is limited in its transferability to authentic contexts because laboratory conditions do not replicate real-world physical activity and decision-making scenarios. Creating valid, reliable methodologies to assess physiological and behavioral responses under varying physical and cognitive demands using virtual reality (VR) environment addresses this limitation. This study determined the feasibility of using VR to investigate the effects of dual-tasking on healthy young adults' cognitive performance.

Today, children are less active than previous generations leading to an increased prevalence of morbidity associated with physical inactivity. Globally, full-day preschool is rapidly becoming the norm. Thus, the amount of time that a child spends outside the home is an opportunity for schools and teachers to educate children about the importance of participating in physical activity and making healthy eating choices.

: Brain network modularity is a principle that quantifies the degree to which functional brain networks are divided into subnetworks. Higher modularity reflects a greater number of within-module connections and fewer connections between modules, and a highly modular brain is often interpreted as a brain that contains highly specialized brain networks with less integration between networks. Recent work in younger and older adults has demonstrated that individual differences in brain network modularity at baseline can predict improvements in performance after cognitive and physical interventions.
