Association between maternal education and objectively measured physical activity and sedentary time in adolescents.

Background: Investigating socioeconomic variation in physical activity (PA) and sedentary time is important as it may represent a pathway by which socioeconomic position (SEP) leads to ill health. Findings on the association between children's SEP and objectively assessed PA and/or sedentary time are mixed, and few studies have included international samples.

Objective: Examine the associations between maternal education and adolescent's objectively assessed PA and sedentary time.

Evaluation of the walkable neighborhoods for seniors project in Sacramento County.

The Walkable Neighborhoods for Seniors project was implemented to foster the creation and promotion of safe and accessible neighborhood walking routes for seniors. This article describes a case study of the efforts put forth by a local task force jointly managed by the Sacramento County Department of Health Services and WALK Sacramento. To facilitate environmental and policy changes that would enable and encourage walking by older adults, these local lead agencies implemented several strategies including organizing a community task force with broad professional and civic representation, conducting environmental audits of selected walking routes, creating walking groups, and advocating for environmental and policy change.

Evaluating the sustainability of SPARK physical education: a case study of translating research into practice.

Dissemination and sustainability of evidence-based physical education programs (PE) has been studied rarely. The sustainability of a health-related PE program (SPARK) was independently evaluated in 111 elementary schools in 7 states. Surveys were mailed to schools that had received SPARK curriculum books, training and follow-up (response rate = 47%).

Exercise Intensity Reproduction: Children versus Adults.

Seventeen children, ages 8-14 years, were compared to an adult group ( = 19) in their ability to execute prescriptive exercise using the Borg 6-20 rating of perceived exertion (RPE) scale. Subjects cycled at a controlled pace (setting resistance) for 2 minutes or traveled one lap of a 400-meter track at four RPE levels: 7, 10, 13, and 16. Results indicated that for pace-controlled cycling, children were similar to adults, reproducing four incremental intensities.
