Methods: A quasi-experimental design was used to collect proof of concept and feasibility data for the ACTIVE YOU intervention as part of teacher education. Conclusions: Examination of a diverse sample of preservice teachers during their fieldwork revealed that those who engage in healthy behaviors and had positive attitudes toward physical activity in schools are more likely to take action and promote physical activity for their students.

The present study examined the effect of acute high-intensity aerobic exercise on prefrontal-dependent cognitive performance and brain-derived neurotrophic factor (BDNF). Fifty-eight young adults were randomly assigned to one of two experimental groups: (a) an acute bout of high-intensity exercise (n=29) or (b) a non-exercise control (n=29). Participants in the exercise group improved performance on inhibitory control in Stroop interference and on cognitive flexibility in Trail Making Test (TMT) Part-B compared with participants in the control group and increased BDNF immediately after exercise. There was a significant relationship between BDNF and TMT Part-B on the pre-post change following exercise. These findings provide support for the association between improved prefrontal-dependent cognitive performance and increased BDNF in response to acute exercise. We conclude that the changes in BDNF concentration may be partially responsib...

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. Three dual-tasking conditions (i.e., standing, preferred-paced walking, and fast-paced walking, each with blocked congruent and incongruent tasks) were developed. Using a within-subjects, randomized design, thirty-two young adults (17 female, mean age = 21.03 ± 2.86) were randomly assigned to a starting condition but experienced all three conditions. Physiological responses of heart rate (HR) and accelerometry data measured energy expenditure as the physical demand. ...

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). A total of 22 physical education teachers and 167 children from five different elementary schools were involved in the process. The procedure includes the Self-Determination Theory (SDT) that provides a theoretical framework that plays a vital role in motivating students to have a physically active lifestyle. This study applied ...

In this paper, we describe Project SMART, which directly targets childhood physical activity within the elementary school. The basis of Project SMART is a cooperative educational game originally designed to raise kids awareness of sustainable active transportation to and from school. In Project SMART, we adapt this game to focus on the health and educational benefits of moderate to vigorous physical activity, leveraging organized physical activity opportunities during the school day. In the game, a class cooperatively earns credit for performing physical activity. This credit takes the form of distances traveled on a virtual path (e.g., along Route 66 across the United States). As the class makes progress, they unlock waypoints that contain l...
