Accelerometer Data Collection and Processing Criteria to Assess Physical Activity and Other Outcomes: A Systematic Review and Practical Considerations

  • Published on March 16, 2017

Background: Accelerometers are widely used to measure sedentary time, physical activity, physical activity energy expenditure (PAEE), and sleep-related behaviors, with the ActiGraph being the most frequently used brand by researchers. However, data collection and processing criteria have evolved in a myriad of ways out of the need to answer unique ...


Assessing physical activity in people with posttraumatic stress disorder: feasibility and concurrent validity of the International Physical Activity Questionnaire– short form and actigraph accelerometers

  • Published on Aug. 27, 2014

Background: Posttraumatic stress disorder (PTSD) is reportedly associated with lower rates of physical activity participation despite the known benefits of regular physical activity for improving both mental and physical health. However, no studies have evaluated the validity or feasibility of assessing physical activity within this population resulting in uncertainty around ...


Using accelerometers to measure physical activity in large-scale epidemiological studies: issues and challenges

  • Published on Feb. 2014

Background: The current guidelines for aerobic activity require that adults carry out ≥150 min/week of moderate-intensity physical activity, with a large body of epidemiological evidence showing this level of activity to decrease the incidence of many chronic diseases. Less is known about whether light-intensity activities also have such ...


Safety and feasibility of a home-based six week resistance training program in juvenile idiopathic arthritis

  • Published on Dec. 20, 2013

Background: Juvenile idiopathic arthritis (JIA), among the most common chronic diseases of childhood, can be associated with attenuated physical activity levels, reduced fitness, decreased functionality and pain. This pilot study aimed to determine the safety, feasibility and effect of a six week resistance training program in children with JIA. Methods: ...


Qualitative feasibility of using three accelerometers with 2-3-year-old children and both parents.

  • Published on Sept. 2013

Purpose: This study assessed mothers' opinions about the feasibility and acceptability of using the ActiGraph GT3X+, Actiheart, and activPAL3 with their 2- to 3-year-old children, as well as with themselves and their husbands/partners, for an 8-day period. Method: Six focus groups were run with Pakistani and White British ...


Pre-schoolers in the playground" an outdoor physical activity intervention for children aged 18 months to 4 years old: study protocol for a pilot cluster randomised controlled trial

  • Published on Oct. 9, 2013

Background The pre-school years are considered critical for establishing healthy lifestyle behaviours such as physical activity. Levels of physical activity track through childhood into adulthood, thus establishing habitual physical activity early in life is vital. Time spent outdoors is associated with greater physical activity and playground interventions have been shown ...


Feasibility of using a compact elliptical device to increase energy expenditure during sedentary activities

  • Published on Aug. 8, 2013

Objectives This study aimed to evaluate the feasibility of using a compact elliptical device to increase energy expenditure during sedentary activities. A secondary aim was to evaluate if two accelerometers attached to the elliptical device could provide reliable and valid assessments of participants' frequency and duration of elliptical device use ...


Feasibility study: Comparison of performance status with objective physical activity monitors in lung cancer patients

  • Published on July 21, 2010

Context Performance status (PS) is a predictor of response to chemotherapy but difficult to identify in patients with advanced lung cancer. It is measured using the ECOG scale, which relies on simple questions to assign a score. Accuracy in measurement is a concern. PS is closely related to physical activity, ...


Modelling accelerometer data from 7-year old British children using functional analysis of variance

  • Published on Sept. 2011

Background There is increasing evidence of the impact of physical activity (PA) in childhood on future health and well-being. The use of accelerometers in population-based studies provides objectively measured activity levels, although there are very few studies using this technology to collect data from young children. The resulting data are ...
