Background Active commuting to/from school is an important source of physical activity that has been declining over the past years. Although it is an affordable and simple way of increasing physical activity levels it is still unclear whether it has enough potential to improve health. Therefore, the aim of ...
Background Despite overwhelming evidence of the health benefits of physical activity, most American youth are not meeting the 60 minutes per day recommendation for moderate- to vigorous-intensity physical activity (MVPA). Policy changes have the potential to bring about substantial increases in physical activity in youth, within school and community settings. Purpose ...
Background During childhood and adolescence, both physical activity (PA) and sedentary behaviour seem to influence cardiorespiratory fitness (CRF); however, the combined association of PA and sedentary behaviour remains to be understood. We analysed the combined association of objectively measured sedentary behaviour and moderate-to-vigorous intensity PA (MVPA) on CRF in Portuguese ...
Objective To explore the effects of an innovative school-based intervention for increasing physical activity. Methods 226 children (5–7 years old) randomly selected from 12 Australian primary schools were recruited to a cluster randomised trial with schools randomly allocated to intervention or control conditions. The 13-week intervention comprised: (1) altering the school playground by introducing ...
Background Although school-based interventions to promote physical activity in adolescents have been suggested in several recent reviews, questions have been raised regarding the effects of the strategies and the methodology applied and for whom the interventions are effective. The aim of the present study was to investigate effects of a ...
Purpose To review recently published studies on the reproducibility, validity, and feasibility of motion sensors used to assess physical activity in healthy children and adolescents (2-l1 yr). Methods In October 2004, a systematic literature search in PubMed, EMBASE, and PsyclNFO was performed. This search has been updated in October 2007. In this ...
Background and Purpose Building on interventions promoting active physical education (PE) and other strategies, school districts and states have initiated policies and programs to improve physical activity levels. in March 2010, the Boston Public Health Commission received Communities Putting Prevention to Work (CPPW) funding. in one initiative, the Boston Public Schools (...
Background and Purpose Schools are an important setting for providing physical activity opportunities, but children's physical activity varies drastically across schools. Identifying specific school practices that are related to children's physical activity during school could inform policies and interventions. Objectives To investigate the relation of elementary school physical activity practices ...
Background and Purpose Active travel to school has been widely promoted as a means to reverse the obesity epidemic. Abundant evidence indicates built environments influence parental decisions on children’s school commuting mode. There has been a growing interest in using portable instruments such as Global Positioning System (GPS) units ...
Background and Purpose Youth across the United States are insufficiently active. Emerging literature has identified numerous perceived correlates of physical activity in youth but many studies rely on associations with self-reported physical activity. However, a recent review of studies utilizing perceived environmental correlates and objectively-measured physical activity in youth concluded ...
