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 ...

Combining Accelerometers with GPS to Investigate Children’s Outdoor Physical Activity

  • Added on June 16, 2011

Introduction With increasing interest in how the physical environment may influence physical activity, methods are needed that can be used to investigate the environmental context of activity. The aim of this study is to use combined accelerometer and GPS data to describe the level and location of children’s physical ...

Identification of Children's Activity Type with Accelerometer-Based Neural Networks

  • Added on June 16, 2011

Introduction Children’s physical activity has traditionally been measured with self-reports. Self-reports are easily administered, low-cost measurements. However, they do not capture the sporadic short-burst nature of children’s physical activity very well. Accelerometers have therefore, in recent times, become the method of choice in physical activity research. These devices ...

Measuring Total Sitting Time in Working Adults

  • Added on June 16, 2011

Introduction Much of the research about sitting measurement has focused on total sitting time [1] (Rosenberg et al) and leisure-time sedentary behaviours [2] (Clark et al 2009), with less attention given to other domains in which sitting and sedentary behaviours occur. This study aimed to assess the measurement properties of a measure of ...
