With the increasing popularity of consumer activity trackers, which provide users with information about physical activity measures such as steps taken and energy expenditure along with easily monitored physical activity tools and goals, provides a potentially powerful tool for use in populations
The researchers compared different activity monitor results during treadmill and simulated free-living activities to manually counted steps using the StepWatch (SW). Hickey and colleagues recruited fifteen participants to perform laboratory-based treadmill exercise at varying speeds and simulated free-living activities, such as cleaning a room, while wearing different activity monitoring devices (including activPAL, Omron HJ720-ITC, Yamax Digi- Walker SW-200, two ActiGraph GT3Xs in “low-frequency extension” and in “normal-frequency” mode, an ActiGraph 7164, and an SW).
