Background: Prevalence and consequences of obesity and sedentary lifestyle are well-documented public health concerns for youth in the United States of America (USA) that disproportionally affect children from low income and minority families. Objective: This mixed-method study focused on estimating levels of physical activity and sedentary…

Youth physical activity (PA) levels are a central focus for physical educators and health professionals worldwide. This study (a) examined the PA levels of children during structured and unstructured PA lessons of an after-school program (ASP) and (b) described the children's perceptions of structured and unstructured PA. Participants were 31…

School-based physical activity (PA), including activity during physical education (PE) lessons and after-school hours, is a possible opportunity for increasing children's daily PA. The purposes of this study were (a) to compare children's school-based PA levels during PE lessons and after-school hours and (b) to examine whether there is a…

Background: Out-of-school time (OST) programs are an important setting for supporting student health and academic achievement. This study describes the prevalence and characteristics of school-based OST programs, which can inform efforts to promote healthy behaviors in this setting. Methods: A nationally representative sample of public elementary…

Child inactivity, overweightness, and obesity are recognized problems in the United States. Despite characterization as an "epidemic," children continue to fall short in meeting physical activity recommendations necessary to maintain proper health. Relevant literature indicates that after-school programs (ASPs) are viable options for…

SHAPE America -- Society of Health and Physical Educators has targeted youth physical activity (PA) as 1 of its 4 goals within the 50 Million Strong[TM] campaign. Only 27.1% of youth met the target of all students (preK-12) participating in at least 60 min of PA that increases their heart rate enough to breathe hard at least some of the time for…

Physical activity has many health, social, and academic benefits for youth (United States Department of Health and Human Services [USDHHS], 2008). It can help children and adolescents improve cardiorespiratory fitness, build strong bones and muscles, maintain a healthy weight, reduce symptoms of anxiety and depression, and reduce the risk of…

Recent estimates suggest that youth spend approximately 80-93% of their working hours in a sedentary state, such as sitting or resting longer than usual (Institute of Medicine, 2013). Schools are conducive of this sedentary behavior and because of that, they have been identified as viable locations for children to be physically active. In order…

Taking a comprehensive approach to wellness--which includes healthy eating and physical activity and extends to additional aspects of health, such as social and emotional skills and competencies--can provide the necessary supports to help healthy children grow into healthy adults. Afterschool and summer learning programs are well-situated to be an…

This evidence guide provides detailed research summaries on the effectiveness of specific afterschool programs for improving outcomes for students in grades K-12. The purpose of the guide is to present information that education agencies, afterschool providers, and others can use as they make decisions about afterschool programming. The guide is a…

Background: Wearable and mobile technologies are often used by people who wish to document their own health and lifestyle behaviors. The feasibility of health tracking among youth is unclear, particularly in low-resource communities where health strategies stand to have the greatest impact. Methods: Youth (n = 24) enrolled in an afterschool…

Background: Physical activity is beneficial for adolescent health. The physical activity patterns of Japanese adolescents are relatively unknown. Therefore, this study aimed to describe the current patterns of physical activity and to identify sex and grade differences among them. Methods: The participants comprised 714 Japanese adolescents aged…

Objective: Examine after-school activity patterns, eating behaviors, and social environment of overweight and normal weight middle school students. Design: Eating and physical activity behaviors of 141 students, ages 10-14, were monitored. Students completed a diary documenting type of activity, location, adult supervision, accompanying…

State and national organizations recently developed policies focused on increasing physical activity (PA) in afterschool programs (ASPs). These policies emphasize "activity friendly" environment characteristics that, when present, should lead to higher levels of PA and reduce the amount of time children spend sedentary during an ASP.…

Afterschool programs have continued to grow in sophistication, increase their offerings and improve quality. As the role of afterschool programs has evolved from primarily providing a safe and supervised environment to a resource that provides a host of supports for their students, programs have become valuable partners in helping students reach…
