The Contribution of School Breaks to the All-day Physical Activity of 9- and 10-year-old Overweight and Non-overweight Children

  • Published on August 2012

Objectives This study examines whether moderate-to-vigorous physical activity (MVPA), in at least 30-min school breaks (SB), helps to achieve the health-related amount of daily physical activity (PA) and whether these exercises influence after-school PA. Methods The ActiTrainer-based PA was monitored over two school days in 239 children aged from 9 to 10 (57.3% female; 20.1% ...




Schoolyard Physical Activity on 6 Schools in Denmark – Using GPS, Accelerometry and GIS

  • Added on March 13, 2012

Background Schools provide a unique setting for the promotion of physical activity (PA) in children through structured physical education, recesses, extracurricular sports and promotion of community activities. Because recesses may contribute up to 40% of moderate/vigorous activity, approaches that increase activity during recess are of interest. A number of recent ...



Modeling Physical Activity Outcomes From Wearable Monitors

  • Added on January 23, 2012

Although the measurement of physical activity with wearable monitors may be considered objective, consensus guidelines for collecting and processing these objective data are lacking. This article presents an algorithm embodying best practice recommendations for collecting, processing, and reporting physical activity data routinely collected with accelerometry-based activity monitors. This algorithm is ...


The Strathclyde Evaluation of Children's Active Travel (SE-CAT): Study Rationale and Methods

  • Added on December 30, 2011

The school commute is a prime opportunity to increase children's physical activity levels. However, active commuting has decreased over the past 40 years. Strategies that increase walking to school are therefore needed. Travelling Green (TG) is a school-based active travel resource aimed at increasing children's walking to school. The resource consists ...


Identification and Validity of Accelerometer Cut-Points for Toddlers

  • Added on December 15, 2011

The purpose of this study was to derive ActiGraph cut-points for sedentary (SED), light-intensity physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) in toddlers and evaluate their validity in an independent sample. The predictive validity of established preschool cut-points were also evaluated and compared. Twenty-two toddlers (mean age = 2.1 years ± 0.4 years) ...


Association Between Objectively-Measured Physical Activity and Sleep, NHANES 2005–2006

  • Added on December 1, 2011

Statement of Problem Epidemiological studies examining the association between physical activity and sleep have relied on self-report measures of physical activity and have primarily been conducted in older adults. Therefore, to address these gaps in the literature, the purpose of the present study was to examine the association between objectively-measured ...


Day Length and Weather Effects on Children's Physical Activity and Participation in Play, Sports and Active Travel

  • Added on November 18, 2011

Background/Aims Proponents of the Daylight Saving Bill currently under consideration in the UK parliament have hypothesised that extending afternoon daylight would promote child physical activity. Our aim was to investigate the relative contribution of day length and weather to children's physical activity, and the behavioural mediators underlying these effects. ...
