Comparison of Two Accelerometers for Assessment of Physical Activity in Preschool Children

  • Published on 2004

Purpose The primary aim of this study was to test the validity of two accelerometers, CSA/MTI WAM-7164 and Actiwatch, against direct observation of physical activity using the Children’s Physical Activity Form (CPAF). Methods CSA/MTI WAM-7164 and Actiwatch accelerometers simultaneously measured activity during structured-play classes in 3- to 4...


Commuting to School: Are Children Who Walk More Physically Active?

  • Published on 2003

Background The journey to school is an opportunity for increasing children’s daily physical activity. However, the contribution that active commuting to school makes to overall physical activity is unknown. This study used objective measurement to investigate the physical activity patterns of children by mode of travel To school. Methods ...


Clinimetric Review of Motion Sensors in Children and Adolescents

  • Published on November 2006

Background and Objectives To review the clinimetric quality of motion sensors used to assess physical activity in healthy children and adolescents (2-18 years). Methods A systematic literature search was performed in PubMed, Embase, and SpycINFO. The clinimetric quality of two pedometers (Digi-Walker3 Pedoboy), four one-dimensional accelerometers (LSI, Caltrac, Actiwatch, CSA/...


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 ...
