Discrepancies between methods of identifying objectively determined physical activity
Article Abstract:
Published Actigraph accelerometer intensity cut points are compared with cut points based on intensity thresholds for heart response to physical activity (PA) in order to determine the probable causes for weak associations in validation studies. It was suggested that the technique used for studying the Actigraph activity data could cause great discrepancies in the summary measure of minutes of moderate and vigorous activity during free-living movement.

Compendium of physical activities: an update of activity codes and MET intensities
Article Abstract:
This article presents a standardized method of classifying physical activities according to activity type and intensity level. Each activity is assigned a numerical code and a MET value that represents a ratio of the working metabolic rate for the task and a standard resting rate.
