Physical activity in the United States measured by accelerometer

  • Added on June 1, 2008

PURPOSE To describe physical activity levels of children (6-11 yr), adolescents (12-19 yr), and adults (20+ yr), using objective data obtained with accelerometers from a representative sample of the U.S. population. METHODS These results were obtained from the 2003-2004 National Health and Nutritional Examination Survey (NHANES), a cross-sectional study of ...

Calibration of an accelerometer during free-living activities in children

  • Added on February 1, 2007

OBJECTIVE: 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. METHODS: The children performed a series of activities (lying, sitting, slow walking, fast walking, hopscotch ...

Calibration of accelerometer output for children

  • Added on November 1, 2005

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 ...
