Reliability and validity of the French version of the global physical activity questionnaire

  • Published on Aug 15, 2016

Background: The Global Physical Activity Questionnaire (GPAQ) has been used to measure physical activity (PA) and sedentary time in France, but no study has assessed its psychometric properties. This study aimed to compare the reliability as well as criterion and concurrent validity of the French version of the GPAQ with ...


Does home equipment contribute to socioeconomic gradients in Australian children’s physical activity, sedentary time and screen time?

  • Published on Aug 5, 2016

Background: Activity behaviours (physical activity, sedentary time and screen time) have been linked to health outcomes in childhood. Furthermore, socioeconomic disparities have been observed in both children’s activity behaviours and health outcomes. Children’s physical home environments may play a role in these relationships. This study aimed to examine ...


Permanent play facility provision is associated with children’s time spent sedentary and in light physical activity during school hours: A cross-sectional study

  • Published on Dec 2016

Objective: To study the associations between: 1) number of permanent outdoor play facilities per pupil and 2) the size of the outdoor play area per pupil with sedentary time and physical activity (PA) during school hours in six-, nine-, and 15-year olds. We conducted a cross-sectional study of nationally representative samples of ...


Measuring moderate-intensity walkingin older adults using the ActiGraph accelerometer

  • Published on 2016

Background: Accelerometry is the method of choice for objectively assessing physical activity in older adults. Many studies have used an accelerometer count cut point corresponding to 3 metabolic equivalents (METs ) derived in young adults during treadmill walking and running with a resting metabolic rate (RMR) assumed at 3.5 mL · kg−1·...


Methodology to Promote Physical Activity Monitoring Adherence in Youth with Autism Spectrum Disorder

  • Published on Sep 27, 2016

Background: Objective physical activity (PA) monitoring via accelerometry is both costly and time consuming. Furthermore, overall adherence to a monitoring protocol is often complicated by disability. Therefore, it is essential that strategies for supporting accelerometer wear for youth with disabilities are maximized. The purpose of this perspective was to provide ...


Calibrating physical activity intensity for hip-worn accelerometry in women age 60 to 91 years: The Women’s Health Initiative OPACH Calibration Study

  • Published on 2015

Objective: We conducted a laboratory-based calibration study to determine relevant cutpoints for a hip-worn accelerometer among women ≥60 years, considering both type and filtering of counts. Methods: Two hundred women wore an ActiGraph GT3X+ accelerometer on their hip while performing eight laboratory-based activities. Oxygen uptake was measured using an ...


Comparison of physical activity assessed using hip- and wrist-worn accelerometers

  • Published on Feb 2016

Objectives: It is unclear how physical activity estimates differ when assessed using hip- vs wrist-worn accelerometers. The objective of this study was to compare physical activity assessed by hip- and wrist-worn accelerometers in free-living older women. Design: A cross-sectional study collecting data in free-living environment. Methods: Participants were from the ...


Classification of physical activity intensities using a wrist-worn accelerometer in 8-12-year-old children.

  • Published on 11 Apr, 2016

Background: Population-specific accelerometer cut-points are required to accurately determine the accumulation of physical activity of various intensities. Objectives: A calibration study was conducted (i) to determine the cut-points for the ActiGraph GT3X+, non-dominant, wrist-mounted accelerometer in children aged 8-12 years and (ii) to compare classification accuracies among the accelerometer's ...


Correlates of objectively measured physical activity in cardiac patients.

  • Published on 6 Oct, 2014

Cardiac patients would benefit from increasing their physical activity (PA) levels. Understanding of factors that influence cardiac patients' PA participation would benefit the development of effective interventions. Therefore, the purpose of this study was to determine correlates of objectively-measured PA in cardiac patients. Participants were 65 cardiac patients (74% male, 95% white), age 58.6...


Independent and joint associations of physical activity and fitness with fibromyalgia symptoms and severity: The al-Ándalus project

  • Published on 12 Sep, 2016

We examined independent and joint associations of objectively measured physical activity (PA) and physical fitness (PF) with pain, fatigue and the overall impact of fibromyalgia in 386 fibromyalgia women aged 51.2 ± 7.6 years. Levels of PA (light, moderate and vigorous) and PF were measured with triaxial accelerometry and the Senior Fitness Test, ...
