Feasibility Study to Simultaneously Objectively Assess Activity and Location of Hispanic-American

  • Added on June 14, 2012

Background Hispanic-American preschool children have higher rates of obesity and Hispanic-American youth may be at higher risk for sedentary lifestyles and metabolic syndrome. Both physical and social environmental factors influence young children’s physical activity. The ability to simultaneously capture objective measurement of physical activity and location of young Hispanic-American ...



Calibration of Two Objective Measures of Physical Activity for Children

  • Published on 12/01/2008

A calibration study was conducted to determine the threshold counts for two commonly used accelerometers, the ActiGraph and the Actical, to classify activities by intensity in children 5 to 8 years of age. Thirty-three children wore both accelerometers and a COSMED portable metabolic system during 15 min of rest and then performed up ...


The Contribution of School Breaks to the All-day Physical Activity of 9- and 10-year-old Overweight and Non-overweight Children

  • Published on August 2012

Objectives This study examines whether moderate-to-vigorous physical activity (MVPA), in at least 30-min school breaks (SB), helps to achieve the health-related amount of daily physical activity (PA) and whether these exercises influence after-school PA. Methods The ActiTrainer-based PA was monitored over two school days in 239 children aged from 9 to 10 (57.3% female; 20.1% ...


Schoolyard Physical Activity on 6 Schools in Denmark – Using GPS, Accelerometry and GIS

  • Added on March 13, 2012

Background Schools provide a unique setting for the promotion of physical activity (PA) in children through structured physical education, recesses, extracurricular sports and promotion of community activities. Because recesses may contribute up to 40% of moderate/vigorous activity, approaches that increase activity during recess are of interest. A number of recent ...



Agreement Between activPAL and ActiGraph for Assessing Children's Sedentary Time

  • Added on February 19, 2012

Background Accelerometers have been used to determine the amount of time that children spend sedentary. However, as time spent sitting may be detrimental to health, research is needed to examine whether accelerometer sedentary cut-points reflect the amount of time children spend sitting. The aim of this study was to: a) ...


Validation of a Hip-Worn Accelerometer in Measuring Sleep Time in Children

  • Added on January 3, 2012

This study compared measures of sleep from an accelerometer worn on the hip to measures obtained from an accelerometer worn on the wrist, the gold standard measure of sleep behavior in community research. The accelerometer worn on the hip provides a measure of total sleep time in 10- to 11-year-old ...


The Strathclyde Evaluation of Children's Active Travel (SE-CAT): Study Rationale and Methods

  • Added on December 30, 2011

The school commute is a prime opportunity to increase children's physical activity levels. However, active commuting has decreased over the past 40 years. Strategies that increase walking to school are therefore needed. Travelling Green (TG) is a school-based active travel resource aimed at increasing children's walking to school. The resource consists ...


Identification and Validity of Accelerometer Cut-Points for Toddlers

  • Added on December 15, 2011

The purpose of this study was to derive ActiGraph cut-points for sedentary (SED), light-intensity physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) in toddlers and evaluate their validity in an independent sample. The predictive validity of established preschool cut-points were also evaluated and compared. Twenty-two toddlers (mean age = 2.1 years ± 0.4 years) ...
