ABSTRACT
Introduction: The novel COVID-19 disease detected in 2019 widely affected individuals' social movements, likely disrupting the ability to participate in leisure-related physical activity. Because of this, participation in sedentary behavior is thought to have increased. The purpose of this study was to determine how the COVID-19 pandemic affected U.S. young adult physical activity and sedentary behavior. Methods: A total of 333 U.S. young adults (aged between 18 and 30 years) completed an online, comprehensive questionnaire during the early parts of COVID-19. Wilcoxon signed-rank tests were used to determine the change in time spent in physical activity and sedentary behavior during COVID-19 compared with that before COVID-19. Results: There was a significant decrease in physical activity minutes (p<0.0001) and a significant increase in sedentary behavior (p<0.005) during COVID-19 compared with that before COVID-19. Significant differences were found by stratifying the data by sex and relationship status. Although both males and females reduced their physical activity, only males significantly increased their time in sedentary behavior during COVID-19 compared with that before COVID-19 (p<0.05). Furthermore, married young adults significantly reduced their physical activity during COVID-19 (p<0.001), whereas single individuals did not. Single young adults saw significant increases in sedentary behavior during COVID-19 (p<0.005), whereas married individuals did not exhibit any change in sedentary behavior. Conclusions: Stay-at-home orders enforced in the U.S. during the summer of 2020 led to increases in sedentary behavior and decreases in physical activity, particularly among males and single young adults. Future studies should determine whether these behavior changes persist.
ABSTRACT
Emerging adulthood is a developmental stage influenced by the regularity of healthy behaviors. Gamification is the motivational strategy using virtual rewards and social comparison. This study aimed to explore the feasibility and proof of concept of utilizing digital badges, leaderboards, and quests as gamified learning in a health course. All data were collected using a pre/posttest format from first-year college students (n = 159; female = 42%). Employing a quasi-experimental design with the students in gamified/non-gamified conditions, Fitbit monitored physical activity (PA), and healthy eating (survey and diet recall) pre/post treatment. A covariance analysis demonstrated that gamification positively influenced students' participation in light PA (p = .035, η2 = 0.03) and healthy eating (p = .008, η2 = 0.049) over the content matched control group. Integrating gamified elements into health education is feasible and advantageous to increase participation in activities such as walking and healthy eating.
ABSTRACT
BACKGROUND: Based on the Health Belief Model, this study examined preservice teacher attributes and attitudes toward providing physical activity opportunities for children in school. 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.
ABSTRACT
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. METHODS: This study used a quasi-experimental design to examine preschoolers' executive functions following indoor compared to outdoor play. A total of 72 children (mean age = 4.5 years, 46% female, 73% non-Hispanic White) participated in task-based assessments of attention shifting and inhibitory control and in classroom observations of attention and inhibitory control. A subsample of the children (n = 51) was assessed for physical activity using accelerometry to examine the extent to which young children's physical activity during outdoor play predicted their subsequent executive functions better than their physical activity during indoor play. RESULTS: Children showed greater attention during classroom circle time following outdoor play compared to after indoor play (d = .34). Children's non-sedentary activity during indoor play was not related to their subsequent task-based executive functions but showed negative associations with their subsequent classroom-based executive functions. Children's percentage of time spent in non-sedentary physical activity during outdoor play showed a quadratic association with subsequent task-based inhibitory control but linear associations with subsequent classroom-based attention and inhibitory control during circle time. CONCLUSION: Periods of outdoor play that involve recommended amounts of physical activity may help young children engage executive functions when they return to the classroom.

BACKGROUND: Play is essential for child growth and development, and may have academic and social-emotional implications. To understand the relationship between in-school play opportunities and academic achievement (AA) and social-emotional well-being among elementary school students, a systematic review of the current in-school play literature was conducted. METHODS: Keywords were input across 7 search engines. After screening, 20 peer-reviewed publications related to play, AA, and social-emotional well-being met the inclusion criteria for this review. FINDINGS: Across the included publications, recess was the only in-school play opportunity assessed. Overall, student behavior and social-emotional outcomes benefited from more recess while mixed results were found between recess participation and academic outcomes. However, more recess was not detrimental to AA. CONCLUSION: The findings from this review support the need for recess as part of a whole child approach to education that may mitigate the negative outcomes of sitting through long periods of instruction. More research is needed on the AA and social-emotional effects of other types of in-school play opportunities (ie, centers, play stations, and other breaks). Findings from this review indicate that recess is a necessary part of the elementary school day.

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 (M = 4.5 years, 46% female) who wore accelerometers to measure their activity during indoor and outdoor free -play (N = 315,061 s). An hour of indoor play was insufficient for most children to reach 15 min of physical activity. When outside, most children reached 15 min of physical activity after slightly more than 30 min. Children engaged in outdoor activity sporadically (1.7 starts/stops per minute). Most physical activity occurred in bouts shorter than 20 s. Indoor free-play does not, on its own, provide sufficient opportunity for preschoolers to engage in physical activity consistent with health guidelines. As a result, outdoor play for at least 30 min at a time has a key role in meeting these guidelines.

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 = 4.5 years). Set to record data each second, these devices collected information about children's movement (N = 140,564 observations). From these data, the authors extracted concrete behaviors hypothesized to index behavioral regulation and compared them with teacher and observer ratings of the same. Initiating movement more frequently, staying seated in activities for shorter amounts of time, and spending a greater amount of time in motion were related to lower ratings of attention and inhibitory control by teachers and by observers of classroom group time, median r = .45, p < .01. These same objectively measured behaviors showed only weak associations with children's performance on assessments of cognitive regulation, median r = .11, p = .47. The findings indicate that ambulatory accelerometers can capture movement-based indicators of children's behavioral regulation in the classroom setting and that performance on measures of cognitive regulation does not strongly predict children's behavior in the classroom. As an unobtrusive and objective measure, actigraphy may become an important tool for studying children's behavioral regulation in everyday contexts.

With the outbreak of the COVID-19 pandemic in 2020, most colleges and universities move to restrict campus activities, reduce indoor gatherings and move instruction online. These changes required that students adapt and alter their daily routines accordingly. To investigate patterns associated with these behavioral changes, we collected smartphone sensing data using the Beiwe platform from two groups of undergraduate students at a major North American university, one from January to March of 2020 (74 participants), the other from May to August (52 participants), to observe the differences in students' daily life patterns before and after the start of the pandemic. In this paper, we focus on the mobility patterns evidenced by GPS signal tracking from the students' smartphones and report findings using several analytical methods including principal component analysis, circadian rhythm analysis, and predictive modeling of perceived sadness levels using mobility-based digital metrics. Our findings suggest that compared to the pre-COVID group, students in the mid-COVID group generally 1) registered a greater amount of midday movement than movement in the morning (8-10 a.m.) and in the evening (7-9 p.m.), as opposed to the other way around; 2) exhibited significantly less intradaily variability in their daily movement; 3) visited less places and stayed at home more everyday, and; 4) had a significant lower correlation between their mobility patterns and negative mood.
ABSTRACT
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). 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 SDT and IMP to develop and pilot a PA intervention called Project SMART using an integrative community participatory approach. As a pilot PA intervention, Project SMART is an online educational game where the students navigate a virtual journey across the United States A class's aggregate PA propels the students on their journey, where standards-based modules are unlocked to achieve STEM (science, technology, engineering, and math) and social-emotional learning outcomes while gaining an understanding of the importance of health behaviors and opportunities to habitually engage in healthy decision-making with the support of their peers. Although initially labor intensive for the researchers, the process of tailoring the intervention to the children's contextual and cultural needs has implications for all theoretically grounded and evidence-based PA interventions.
ABSTRACT
OBJECTIVE: In the present study, we sought to determine if a comprehensive school physical activity program (CSPAP) delivered using the Be a Champion! (BAC) framework was effective in increasing moderate-to-vigorous physical activity (MVPA) and decreasing sedentary time in elementary school youth. METHODS: We implemented a CSPAP in 3 elementary schools to determine its effectiveness to youth behaviors compared to 2 control schools. Youth physical activity was assessed via accelerometry in spring 2015 and spring 2016 during school hours on school days. Implementation of the BAC components and youth behavior was assessed through direct observation from fall 2015 through winter 2016. RESULTS: In a multilevel, mixed model examining the effects of intervention, we found no statistically significant effect of the intervention on overall MVPA. However, a significant increase in MVPA was observed among girls (but not boys) in the intervention schools relative to controls. No differences in sedentary behaviors were observed by group. CONCLUSION: CSPAP implementation may be effective in reducing sedentary time and increasing MVPA in girls, but not boys. Research is necessary to increase implementation dose and fidelity to best practices in physical activity promotion.
ABSTRACT
Objectives: In this study, we examined the associations of various sedentary behaviors (SB) to health-related quality of life (HRQOL) and the possible mediating role of sleep quality in these relationships. Methods: Participants were 363 middle-aged adults (Mage = 44.25, SD = 4.72, 64% male) from Amazon MTurk. Self-reported measures of socio-demographic status, time spent doing 10 different types of SB, sleep quality, and HRQOL were collected. Exploratory factor analysis was used to classify SB. Mediation analysis with PROCESS for SPPS examined the mediational paths. Results: Exploratory factor analysis categorized 10 sedentary activities into Common Engaging SB, High Engaging/Leisure SB, and Less Engaging/Passive SB. Findings suggested that Common Engaging SB was negatively associated with HRQOL, whereas High Engaging/Leisure SB was positively related to HRQOL. Sleep quality appeared to mediate the associations of Common Engaging SB and High Engaging/Leisure SB to HRQOL. Conclusions: Reducing sitting time, particularly Common Engaging SB, could be a useful strategy to improve HRQOL. Health promotion programs should support mentally engaging leisure activities because such activities might increase middle-aged adults' HRQOL. Additionally, health promotion programs are needed to raise public awareness regarding the importance of sleep quality.

Individual differences in brain network modularity at baseline can predict improvements in cognitive performance after cognitive and physical interventions. This study is the first to explore whether brain network modularity predicts changes in cortical brain structure in 8- to 9-year-old children involved in an after-school physical activity intervention (N = 62), relative to children randomized to a wait-list control group (N = 53). For children involved in the physical activity intervention, brain network modularity at baseline predicted greater decreases in cortical thickness in the anterior frontal cortex and parahippocampus. Further, for children involved in the physical activity intervention, greater decrease in cortical thickness was associated with improvements in cognitive efficiency. The relationships among baseline modularity, changes in cortical thickness, and changes in cognitive performance were not present in the wait-list control group. Our exploratory study has promising implications for the understanding of brain network modularity as a biomarker of intervention-related improvements with physical activity.

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. RESULTS: To address these limitations, we developed a home environment sensor kit for continuous indoor air quality tracking and deployed it in conjunction with smartphones, Fitbits, and ecological momentary assessments in a cohort study of up to 1,584 college student participants per data type for 3 weeks. We propose a conceptual framework that systematically organizes human-centric data modalities by their temporal coverage and spatial freedom. Then we report our study procedure, technologies and methods deployed, and descriptive statistics of the collected data that reflect the participants' mood, sleep, behavior, and living environment. CONCLUSIONS: We were able to collect from a large participant cohort satisfactorily complete multi-modal sensing and survey data in terms of both data continuity and participant adherence. Our novel data and conceptual development provide important guidance for data collection and hypothesis generation in future human-centered sensing studies.

Purpose: Physical education policies provide guidance and accountability to develop quality programs that increase physical literacy. The purpose of this study was to conduct a systematic review of physical education policy research to explore its effects on the school environment and programming as an essential component of physical education. Methods: Using the PRISMA guidelines of identify, screen, determine eligibility, and include, studies were extracted from four different databases, using search terms related to the essential physical education component of policy and environment. Of the 225 publications identified, 42 studies met the inclusion criteria for this investigation. Each paper was coded, and emergent themes were identified. Results: The policy research was predominantly descriptive and focused on: (a) minutes in physical education (83%), (b) moderate to vigorous physical activity (MVPA; 31%), (c) certified/qualified teachers (24%), (d) exemptions (17%), and (e) student-teacher ratio (12%). Emergent themes of adherence, policy strength, and implementation accountability were identified as influential physical education policy aspects. Conclusions: Policy research over the last 20 years was focused on the regulatory mandate of time. Policy research did not directly address disciplinary process variables of learning activities or outcomes of physical education. The effects of policy exemptions and class size were underrepresented. Themes may explain the lack of reporting student performance as the primary outcome. Further research is needed to examine the downstream effects of physical education policy and determine whether well-written policies increase the number of physically literate individuals.

BACKGROUND: Gamified reward systems, such as providing digital badges earned for specific accomplishments, are related to student engagement in educational settings. The purpose of this study was to conduct a meta-analytic review to quantify the effects of gamified interventions on student behavioral change. METHODS: A meta-analysis was performed using the following databases: The Academic Search Complete, Communication & Mass Media Complete, Education Source, ERIC, Library Information Science & Technology Abstracts, and PsycINFO. Inclusion in the review required: (a) peer-reviewed conducted between 2010 and 2019, (b) experimental controlled design, (c) gamification elements, and (d) educational setting. RESULTS: Using a random-effects model, a statistically significant (Cohen's d (ES) = 0.48, 95% CI = 0.33, 0.62) gamification effect was evidenced by moderate and positive grand effects sizes (ES). Gamification effects were higher with adults in higher education (ES = 0.95) than K-12 students (ES = 0.92). Brief interventions delivered in days or less than 1 week were significantly more effective (ES = 1.57) than interventions lasting up to 20 weeks (ES = 0.30). Interventions incorporating gamification elements across years (ES = -0.20) was adversely associated with behavioral change. CONCLUSIONS: Findings suggest that short-term over longer-term gamified interventions might be a promising way to initiate changes in learner's behaviors and improve learning outcome.

INTRODUCTION: Grounded in organizational change theory, the purpose of this study was to investigate the efficacy of the Presidential Youth Fitness Program (PYFP) and its association with healthy cultures within schools. METHODS: Using a qualitative approach, data were collected through interviews, site visits and artifacts across 374 schools. An explanatory collective case study approach was used to identify key events related to implementation. RESULTS: Pivotal antecedents to organizational change included prolonged, continual PD, direct support of PYFP implementation, and recognition. Further, three key themes of leveling of the playing field, strategically overcoming barriers, and recruiting teacher fitness champions were identified. CONCLUSIONS: Creating a healthy school culture was an unexpected, but feasible outcome stemming from the implementation of the PYFP. A collective effort, led by physical education teachers and fitness champions and embraced by the administration, faculty, and community, is necessary for the school culture to unfreeze from its present status.

BACKGROUND: Physical activity (PA) is beneficial for cognitive and brain health during preadolescence. Given that childhood obesity (OB) is a public health concern, investigating this effect in children with OB is an important societal consideration. OBJECTIVES: To identify the effects of weight status and PA on neuroelectric indices of executive function in preadolescence. METHODS: Children were randomly assigned to a PA intervention or a wait-list control group and completed a task that manipulated inhibitory control, while task performance and neuroelectric (P3 component) outcomes were assessed. About 103 children with OB were matched to a sample of 103 normal weight (NW) children based on treatment allocation and demographic variables. RESULTS: Children with OB in the control group demonstrated reduced P3 amplitude from pre- to post-test, meanwhile those with OB in the PA intervention maintained P3 amplitude at post-test compared to pre-test. Additionally, NW children in the PA intervention group showed that decreased visceral adipose tissue corresponded with faster task performance, a relationship not observed in children with OB. CONCLUSIONS: These results suggest that a 9-month PA intervention may be particularly beneficial to the cognitive and brain health of children with OB. These results are important to consider given the public health concerns associated with childhood OB.

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. One approach to comprehensively offer opportunities for physical activity and healthy eating is called Whole School, Whole Community, Whole Child, which intertwines academic success and promotion of healthy behaviors. Particularly for adolescent children, multicomponent approaches that include both school and family or community involvement have the most significant potential to make meaningful differences in the rate of physical activity participation. For young children, teacher training, resources, and equipment are needed to achieve equity across programs and schools, because these are predictors of physical activity participation. Further, school policies, administrative support, modeling by teachers, and the use of cues and incentives can have a positive effect. The purpose of this paper is to describe the benefits of contemporary, evidence-based models for providing opportunities for health behaviors in school from early childhood to adolescence.

Introduction: 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. The use of brain network modularity as a predictor of training outcomes has not yet been examined in children. Method: In the present study, we examined the relationship between baseline brain network modularity and changes (post-intervention performance minus pre-intervention performance) in cognitive and academic performance in 8- to 9-year-old children who participated in an after-school physical activity intervention for 9 months (N = 78) as well as in children in a wait-list control group (N = 72). Results: In children involved in the after-school physical activity intervention, higher modularity of brain networks at baseline predicted greater improvements in cognitive performance for tasks of executive function, cognitive efficiency, and mathematics achievement. There were no associations between baseline brain network modularity and performance changes in the wait-list control group. Discussion: Our study has implications for biomarkers of cognitive plasticity in children. Understanding predictors of cognitive performance and academic progress during child development may facilitate the effectiveness of interventions aimed to improve cognitive and brain health.
