Background Adolescence is an established period of physical activity decline. Multi-component school-based interventions have the potential to slow the decline in adolescents’ physical activity; however, few interventions have been conducted in schools located in low-income or disadvantaged communities. This study aims to assess the effectiveness of a multi-component school-based intervention ...
Background and Purpose Pedometers are popular, relatively inexpensive tools for objectively measuring physical activity. Pedometers have been used in schools to estimate and monitor student physical activity levels. A few studies have provided mixed evidence demonstrating the validity of pedometers for measuring physical activity levels, and several have suggested pedometer ...
Background and Purpose Research suggests that public transportation (PT) (e.g., bus, rail) users are more physically active than non-users. However, this difference could be explained by other individual or shared environmental factors that differ between PT users versus non-users (e.g., attitudinal predisposition for being active; transit users live ...
Background To contribute to the current debate as to the relative influences of dietary intake and physical activity on the development of adiposity in community-based children.
Methods Participants were 734 boys and girls measured at age 8, 10 and 12 years for percent body fat (dual emission x-ray absorptiometry), physical activity (pedometers, accelerometers); and ...
Objective Little research has investigated children’s physical activity levels during school recess and the contribution of recess to school day physical activity levels by weight status. The aims of this study were to examine non-overweight and overweight children’s physical activity levels during school recess, and examine the contribution ...
Background School recess provides an important opportunity for children to engage in physical activity. Previous studies indicate that children and adults of South Asian origin are less active than other ethnic groups in the United Kingdom, but have not investigated whether activity differs within the shared school environment. The aim ...
Purpose Examine whether nonbout physical activity (i.e., <10 minutes' duration of physical activity [PA]) demonstrates a stronger association with health outcomes than bout physical activity (i.e., ≥10 minutes' duration).
Design Cross-sectional study.
Setting NHANES 2003–2006.
Subjects A total of 6321 participants ranging in age from 18 to 85 years.
Measures Objectively measured PA ...
Aims Worldwide levels of daily physical activity (PA) in children are low. This has negative health consequences. Schools have been recognized as key settings to promote PA. This study evaluates the effectiveness of the playground programme PLAYgrounds on increasing PA.
Methods PLAYgrounds was evaluated by a controlled trial, with a ...
Background The magnitude of the association between physical activity (PA) and obesity has been difficult to establish using questionnaires. The aim of the study was to evaluate patterns of PA across BMI-defined weight categories and to examine the independent contribution of PA on weight status, using accelerometers.
Methods The study ...
Background Physical activity is essential for older peoples’ physical and mental health and for maintaining independence. Guidelines recommend at least 150 minutes weekly, of at least moderate intensity physical activity, with activity on most days. Older people’s most common physical activity is walking, light intensity if strolling, moderate if brisker. ...
