Background To date, nearly all research on physical activity and the built environment is based on self-reported physical activity arid perceived assessment of the built environment. Objective To assess how objectively measured levels of physical activity are related with objectively measured aspects of the physical environment around each participant’s ...
Objective The purpose of this study was to identify the psychosocial and environmental correlates of objectively measured physical activity behavior in a diverse sample of sixth-grade students. Design Cross-sectional. Participants and Settings One hundred ninety-eight sixth-grade students from 4 public middle schools in Columbia, South Carolina. The study group was 52.0% female, 55.1% ...
Purpose The primary purpose of this study was to compare the health-related physical times and physical activity behaviors of Old Order Mennonite children to both rural and. urban-dwelling children living a contemporary Canadian lifestyle. Methods A cross-sectional study design was used to compare the physical fitness and physical activity characteristics ...
There is growing recognition of the role of the environment in influencing health and health behaviours, and an environment that encourages excess energy intake and reduced energy expenditure is widely considered to be a driving force behind population-wide weight gain. Expert bodies have highlighted the importance of environmental factors on ...
Objectives To investigate the use of accelerometers to monitor change in physical activity in a childhood obesity treatment intervention. Methods 28 children aged 7–13 taking part in “Families for Health” were asked to wear an accelerometer (Actigraph) for 7-days, and complete an accompanying activity diary, at baseline, 3-months and 9-months. Interviews with 12 ...
Purpose Three methods for measuring time spent in daily physical activity (PA) were compared during a 21-d period among 83 adults (38 men and 45 women). Methods Each day, participants wore a Computer Science and Applications, inc (CSA) monitor and completed a 1-page, 48-item PA log that reflected time spent in household, occupational, ...
Purpose The purpose of this investigation was 1) to evaluate agreement between dual-mode CSA accelerometer outputs and Yamax pedometer outputs assessed concurrently under free-living conditions; 2) to determine the relationship between pedometer-steps per day and CSA-time spent in inactivity and in light-, moderate-, and vigorous-intensity activities; and 3) to identify a value of ...
Purpose The purpose of this investigation was to compare the concurrent accuracy of the CSA accelerometer and the Yamax pedometer under two conditions: 1) on a treadmill at five different speeds and 2) riding in a motorized vehicle on paved roads. Methods In study 1, motion sensor performance was evaluated against actual steps ...
Purpose The purpose of this study was to establish the accuracy of five published accelerometer regression equations that predict time spent in different intensity classifications during free-living activities. Methods Ten participants completed physical tasks in a field setting for a near-continuous 5 - 6 h-period while oxygen uptake and accelerometer data were ...
Purpose To evaluate the validity of five physical activity monitors available for research: the CSA, the TriTrac-R3D, the RT3, the SenseWear Armband, and the BioTrainer-Pro. Methods A total of 10 healthy men and 11 healthy women performed 10 mm of treadmill walking at 54, 80, and 107 m·min-1 and treadmill running at 134, 161, 188, and 214 m·...
