Measuring the Quality of Public Open Space Using Google Earth

submitted by: Bronwen_Taylor
Background: Proximity to public open space, such as parks and other green spaces, has considerable health benef?ts, and people have been shown to be more likely to use such space for physical activity if it is of high quality. This paper describes a new remote-assessment approach that makes use of Google Earth Pro (the free version of this program is Google Earth) to provide rapid and inexpensive measurement of the quality of public open space. Purpose: The aim of the study was to...

Walk Score as a Global Estimate of Neighborhood Walkability

submitted by: lcarr54
Background: Walk Score recently has been demonstrated as a valid and reliable tool for estimating access to nearby facilities, a critical component of the physical activity environment. It has not yet been determined whether Walk Score relates to other critical components of the physical activity environment, including street connectivity, access to public transit, residential density, and crime. Purpose: The aim of this study was to explore the relationship between Walk Score and...

Translating Physical Activity Recommendations into a Pedometer-Based Step Goal: 3000 Steps in 30 Minutes

submitted by: pssjm3
BACKGROUND: It is a public health recommendation to accumulate at least 150 minutes per week of moderate intensity physical activity. Although pedometers are widely used as a physical activity-monitoring tool, they are unable to measure activity intensity. Translating current physical activity recommendations into a pedometer-based guideline could increase the public health impact of physical activity interventions. METHODS: A community sample of 97 adults (60% women, with a mean age of 32.1...
