Neighborhood Built Environment and Income: Examining Multiple Health Outcomes (2009, background): “Actigraph (Actigraph, Inc; Fort Walton Beach, FL) model 7164 or 71256 accelerometers, with established reliability and validity (Welk, 2002) were used to objectively assess moderate-tovigorous physical activity (MVPA).”
Physical activity in the United States measured by accelerometer. (2008, background): “to certain types of activity, such as bicycling or swimming, not being captured by accelerometers (33).”
IPAQ environmental module; reliability testing (2006, background): “Greater variability within the population and familiarity with the methodology may increase reliability (Welk 2002).”
A Review of Physical Activity Levels During Elementary School Physical Education (2006, background): “Although each of the methods has demonstrated sound validity and reliability amongst pediatric populations, they also have limitations (Welk, 2002).”
Standardizing and Optimizing the Use of Accelerometer Data for Free-Living Physical Activity Monitoring (2005, background): “Human-generated accelerations range from approximately 0 to 60 m/s2 with a frequency response typically less than 10 Hz.9 The capability of these devices, in terms of measuring accelerations in various planes, is dependent on the configuration and orientation of the piezosensor(s).”
