Calibration of accelerometer output for children

  • Added on August 5, 2013

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 ...


A Comparison of Young Children’s Physical Activity Levels in Physical Education, Recess and Exergaming

  • Presented on May 30, 2013

Purpose Recess and other school-based physical activity (PA) programs are important avenues for school children to participate in PA beyond physical education at school (NASPE, 2006). However, the quantification of the contributions of these programs, as compared with physical education, remains largely unexplored. This study was designed to compare young children’...


Development of a New Cell Phone-Based Physical Activity Recall Using Daily Activity Pictures

  • Presented on May 31, 2013

Purpose Self-reported physical activity (PA) has several challenges, including recall errors, social desirability, incomplete answers and misunderstanding of questionnaires. All of these affect PA estimates. To reduce recall errors, daily PA diaries have been used as a criterion for other types of PA questionnaires. The purposes of this study were ...


Contribution of Active Video Game Play to Daily Physical Activity among College Students

  • Presented on May 31, 2013

National surveys indicate less than half of college-age students meet physical activity (PA) guidelines (ACHA, 2009). Additionally, 65% of college students are active video game (AVG) players (Jones, 2003). AVGs incorporate PA into game play and could be used to increase PA. A key step in establishing their efficacy as an intervention tool ...



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

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 ...


Actigraphy as a measure of physical activity for wheelchair users with spinal cord injury

  • Added on March 1, 2004

Background: 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. Objective: To ...
