This study was designed to assess and characterize the physical activity levels and patterns of participants in a hospital-based Phase III cardiac rehabilitation (CR) program.
Subjects consisted of 25 men with a history of coronary artery disease ranging in age from 39 to 69 years who were participating in a Phase ...
The aims of this study were to develop an equation to predict energy expenditure and to derive cut-points for moderate and vigorous physical activity intensity from the Actigraph accelerometer output in children aged 12 years.
The children performed a series of activities (lying, sitting, slow walking, fast walking, hopscotch ...
Understanding the determinants of physical activity behavior in children and youths is essential to the design and implementation of intervention studies to increase physical activity. Objective methods to assess physical activity behavior using various types of motion detectors have been recommended as an alternative to self-report for this population because ...
Research has indicated that actigraphy is valid and reliable for measuring low levels of physical activity among ambulatory individuals, and that it may be a valid indicator of energy expenditure for wheelchair users in laboratory conditions, but there are no reports of its evaluation in free-living conditions.
We established accelerometer count ranges for the Computer Science and Applications, Inc. (CSA) activity monitor corresponding to commonly employed MET categories.
Data were obtained from 50 adults (25 males, 25 females) during treadmill exercise at three different speeds (4.8, 6.4, and 9.7 km x h(-1)).
Activity counts and steady-state oxygen consumption were ...
