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 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 ...
Background and Purpose Research has shown that features of the home, work, and neighborhood environments are associated with sedentary and physical activity in adults. However, little is known about the extent to which objectively measured levels of sedentary and physical activity differ across these settings. According to behavior setting theory, ...
Background and Purpose A growing body of research has linked children‘s physical activity to neighborhood built environmental characteristics. in particular, neighborhood parks and open spaces have garnered much research attention for the opportunities they provide children to engage in physical activity. Studies in this area typically investigate the availability ...
Background Research has suggested that green and natural spaces within the built environment are associated with increased physical activity in children. in particular, parks have been identified as important features in the community for promoting active living. Presence of a neighborhood park may encourage active living simply by drawing residents ...
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 ...
