A Pair-Matched Comparison of Objectively Measured Sedentary and Physical Activity Levels of Obese/Overweight Dogs With Normal Weight Dogs

  • Presented on 2011

Introduction Accurate measurement of canine physical activity (PA) is important in obesity treatment and prevention in veterinary medicine [1]. Methods of PA measurement often rely on owner recall and thus open to the same cognitive problems recognised in human PA measurement [1]. Accelerometry has been shown to be a valid, practical and ...


Measuring Sitting and Standing at Work Separately: Validating the Brief Occupational Sitting and Physical Activity Questionnaire (OSPAQ)

  • Presented on 2011

Introduction Sitting at work is an emerging occupational health risk [1]. Few instruments designed for use in population-based research measure occupational sitting and standing as distinct behaviours [2]. The aim of this study was to develop and validate a brief measure of occupational sitting and physical activity. Methods A convenience sample (N=99, 61% ...





Patterns of Change in Daily Step Counts, Where Does the Change Happen?

  • Presented on 2011

Purpose To examine the change in the average daily steps taken at different cadence (steps/min) levels when a change in total steps/day occurs. Methods A total of 43 people participated in a one week intervention with the goal to increase time spent in moderate-to-vigorous physical activity. Participants wore a ...


Predicting Children's Free-living Energy Expenditure

  • Added on June 16, 2011

Introduction The assessment of energy cost in paediatric populations has typically occurred in laboratory settings, which usually obtain higher validity coefficients. However, laboratory based protocols may be limited in the assessment of free-living behaviours as creating environments that reflect such behaviours is difficult [1]. Few studies have provided children the option ...


Impact of Accelerometer Epochs on Classification of Children Activity Patterns

  • Added on June 16, 2011

Introduction Children have intermittent activity patterns and this must be considered when assessing activity with accelerometers. This study examines the impact of accelerometer epoch duration on the recorded time spent in physical activity during recess. A second goal was to determine whether variability in activity is associated with overall time ...



Comparison of Physical Activity Assessed by Uniaxial and Triaxial Accelerometry in Adolescents under Free-living Conditions: The HELENA Study

  • Added on June 16, 2011

Introduction Different types of accelerometers are available to assess physical activity (PA) patterns levels, and the choice about which to use depends on various factors: cost, physical characteristics (weight, size, and battery life), performance (number of axes, possible epochs, system of data transfer, recording duration, function of the epochs, and ...
