TL;DR: Findings provide insight for understanding the behavioral variability in the activity patterns of adults and suggest that reliable measures of activity behaviors require at least 7 d of monitoring.

TL;DR: Differences in mean steps per day detected may be due to differences in set instrument sensitivity thresholds and/or attachment, and additional studies with different populations are needed to confirm a recommended number of Steps per day associated with the duration and intensity of public health recommendations for ambulatory activity.

TL;DR: Evaluating the absolute and relative validity of three contemporary activity monitors under both laboratory and field conditions found the CSA yielded accurate predictions of energy expenditure (EE), whereas the Tritrac and Biotrainer tended to overestimate the EE (101-136% of measured value).

TL;DR: Findings were consistent with findings from other PA validation studies that show motion sensors, PA logs, and surveys reflect PA; however, these methods do not always provide similar estimates of the time spent in resting/light, moderate, or hard/very hard PA.

TL;DR: Pedometers provide a useful indicator of daily step counts but variability in activity patterns make it difficult to establish step count guidelines that correspond with other public health guidelines.
