Amherst Youth Physical Activity Study

Overview

There we two phases to the Amherst study. In the first phase children were consented into an ActiGraph calibration study. Children 6- to 18-years completed two treadmill walking speeds and one running speed. Respiratory gas exchange was measured using indirect calorimetry and the ActiGraph was worn on the hip and programmed to collect minute-by-minute counts. ( Freedson et al., 2005);

In the second phase of the study children 6- to 18- wore accelerometers and parents of all children completed questionnaires. Children in grades 7-12 also completed questionnaires. Questionnaire data included physical activity and determinants of physical activity. Main study data was collected in Amherst, Mass. under the direction of Patty Freedson. Analyses were performed at the University of South Carolina under the direction of Russell Pate. Reliability data were collected in Texas under the direction of Wendel l Taylor.
