Future research should assess the accuracy of arm-worn and wrist-worn wearable devices in these conditions. Third, in

In Part 2, the number of steps per walking bout was held constant at four for each trial, and the rest interval varied (i.e., 1, 2, 4, 6, 8 and 10 s). Participants took four steps per bout to simulate free-living activities; a bout consisting
