Comparison of postural classification from thigh-worn Actigraph GT3X+ and ActivPal3 accelerometers under laboratory and free-living conditions

  • Presented on May 21, 2014

Purpose: This study compared sitting, standing, and stepping classifications from thigh-worn Actigraph and ActivPAL monitors under laboratory and free-living conditions. Methods: Adults wore both monitors on the right thigh while performing 6 sitting, 2 standing, 8 stepping, and 1 cycling activity under laboratory observation (n=21), and during three days free-living (n=18). Percent of time ...

SenseCam-coded body positions associated with accelerometer-determined cadence

  • Presented on May 21, 2014

Purpose: To quantify the proportion (%) of time spent in different body positions within incremental bands of accelerometer determined cadence (steps/min). Methods: This was a secondary analysis of SenseCam camera images and ActiGraph GT3X+ accelerometer data concurrently worn during waking hours by 40 adults (70% male; 36±12 years-old; BMI=23±3 kg/m2) for 3...

Relationships between PA, sedentary behavior, and subjective well-being in Latinas as a function of measurement method

  • Presented on May 21, 2014

Purpose: To examine (1) associations between objectively measured physical activity (PA) and Subjective Wellbeing (SWB), (2) associations between objectively measured Sedentary Behavior (SB) and SWB; and (3) whether the relationship of PA and SB with SWB varies by PA or SB measurement method (objective vs. self-report). Methods: 146 adult Latinas recruited to a PA ...

The impact of missing Global Positioning System (GPS) signal data on relationships between environmental variables and objectively measured physical activity and sedentary behavior

  • Presented on May 21, 2014

Purpose: Explore environment-related patterns of GPS signal-loss, levels of objectively measured physical activity (PA) during periods of GPS signal loss, and the effect of missing GPS data on relationships between environmental variables, PA and sedentary behavior. Methods: Eight free-living studies using GPS and accelerometer devices were pooled, representing a range ...

Go out and play: Children’s outdoor time and context-specific physical activity by gender

  • Presented on May 21, 2014

Purpose: Being outdoors is as a correlate for enhanced physical activity (PA), but the association has seldom been investigated using objective measures. This paper investigates the association between week day outdoor time and context-specific moderate to vigorous PA (MVPA) by gender. Methods: Children (n=170, 11-16 years old) from the When ...
