). Prior evidence of reliability of the MotionWatch 8 was based on the consistency between recordings across 3 days of wear. Evidence of validity of the MotionWatch 8 was based on a consistent match between the activity counts and recorded activity performed and a statistically significant difference in

accelerometer data. 12 However, raw data are voluminous (usually between 30 and 100 samples per second), making the data harder to manage and interpret. Compared with activity counts, raw data metrics such as Euclidean Norm Minus One have shown promise for improving comparability among different devices, 13

activity among adults living with HIV. Alternatively, Fillipas et al 53 found a weak correlation (.41) between the IPAQ MET-minutes per week with a WPAM (ActiGraph ® ) when recording activity counts (MET categories similar to the categories used in this study) among adults living with HIV. The IPAQ

boys). They wore an Actiheart (CamNtech, Cambridge, UK) for 3 days (2 week-days and one weekend day). This device recorded accelerometry (ACC) and heart rate (HR) data using an epoch setting of 15 s. PAEE was estimated using the branched model equations (activity counts + HR). Physical activity level

Amherst Recent studies have used triaxial accelerometer activity counts to distinguish standing time from sitting time. Further research is needed on methods for classifying standing versus sitting using step-based metrics. Sparsely detected steps peppered into strings of 0 steps/min (i.e., zero cadence

GM competence and PA were assessed using the Bayley Scales of Infant Development – 3rd ed. and ActiGraph GT3X-BT accelerometers. PA was measured over 3 days and the average activity counts per minute at the wrist and ankle were calculated. Rate of weight gain was calculated by entering each infants
