Accelerometers are commonly used in clinical and epidemiological research for more
detailed measures of physical activity and to target the limitations of self‐report methods …

Background Structured settings, such as school, childcare, afterschool programs, summer
camps, and physical activity/sport programs are crucial to promoting physical activity (PA) …

Abstract Purpose The Structured Days Hypothesis (SDH) posits that children's behaviors
associated with obesity–such as physical activity–are more favorable on days that contain …

Background Movement behaviours performed over a finite period such as a 24 h day are
compositional data. Compositional data exist in a constrained simplex geometry that is …

Background Over the last decade use of raw acceleration metrics to assess physical activity
has increased. Metrics such as Euclidean Norm Minus One (ENMO), and Mean Amplitude …

The GT3X+ worn at the wrist promotes greater compliance than at the hip. Minutes in SB and
PA calculated from raw accelerations at the hip and wrist provide contrasting estimates and …

Background This study examined the volume and patterns of physical activity (PA) and
sedentary time (ST) across different segments of the week among boys and girls. Methods A …

Self-reported youth physical activity (PA) is typically overestimated. We aimed to calibrate
and validate a self-report tool among English youth. Four-hundred-and-two participants …

This review re‐examines the use of accelerometer and oxygen uptake data for the
assessment of activity intensity. Accelerometers capture mechanical work, while oxygen …

Schools are key environments in which physical activity (PA) can be promoted. Various
strategies and opportunities should be used to engage children in PA within schools. The …
