Energy intake and expenditure during sedentary screen time and motion-controlled video gaming

submitted by: LIZ_LYONS
BACKGROUND: Television watching and playing of video games (VGs) are associated with higher energy intakes. Motion-controlled video games (MC) may be a healthier alternative to sedentary screen-based activities because of higher energy expenditures, but little is known about the effects of these games on energy intakes. OBJECTIVE: Energy intake, expenditure, and surplus (intake - expenditure) were compared during sedentary (television and VG) and active (MC) screen-time use. DESIGN: Young...

Physical Activity and Other Health-Risk Behaviors During the Transition into Early Adulthood

submitted by: mattkwan
Background: Research consistently demonstrates that physical activity declines with age. However, such declines do not occur linearly. The transition into early adulthood is one period where disproportionate declines in physical activity have been evident, but much of our understanding of such declines among young adults has been based on cross-sectional data or with prospective studies exclusively focused on college/university students. Purpose & Methods: The purpose of the current...

Effects of active video games on body composition: a randomized controlled trial

submitted by: Lfoley
Background: Sedentary activities such as video gaming are independently associated with obesity. Active video games, in which players physically interact with images on screen, may help increase physical activity and improve body composition. Objective: The aim of this study was to evaluate the effect of active video games over a 6-mo period on weight, body composition, physical activity, and physical fitness. Design: We conducted a 2-arm, parallel, randomized controlled trial in...

Integrating Social Capital Into a Park-Use and Active-Living Framework

submitted by: sbroyl
Background: Parks have been proposed as a feature of the built environment that may promote increased physical activity. Little, if any, research has investigated the role of the park social environment in promoting physical activity within parks, however. Purpose: To examine whether social capital is a collective feature of the park environment and whether it is associated with park use and park-based physical activity. Methods: Adult park users (n=222) were surveyed in 27 neighborhood...

Active living for rural children: community perspectives using PhotoVOICE

submitted by: ehenness
BACKGROUND: Active living integrates physical activity into one's daily routine. Current understanding of active living among children and their families living in rural communities is limited. A community perspective is critical to understand the contextual factors that influence children's physical activity in rural areas. PURPOSE: The purpose of this study was to identify the perceived environmental factors that support or hinder physical activity among rural children to develop...

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...

The Bikeability and Walkability Evaluation Table: Reliability and Application

submitted by: shoedl
Background: With increased research on the influence of the built environment on physical activity, methods of assessing environmental attributes have to be developed according to different research requirements. Purpose: The purpose of this paper is to describe the approach to develop and test a simple and eff?cient audit tool to get a quick overview of environmental characteristics along a route or in a neighborhood. Methods: Based on a selection of existing audit instruments, the...
