“…Commercially available wearable technology, and the biofeedback these devices provide, has been embraced by the heath and fitness field [1,2]. These devices have the ability to provide information regarding heart rate during exercise [3,4], overall step count [5,6], estimated energy expended [7,8], and even respiratory-associated measures [9,10]. There are many different wearable device types including wrist-worn monitors [3,4,6], monitors that attach to the hip [8,11,12], wearable garments [13,14], and earbuds [15,16].…”

Footpod monitors are wearable devices attaching to the shoe with the ability to sense oscillations in leg movement; however, few studies provide reliability. The purpose was to provide reliability data for outdoor tasks as measured by the Stryd Power Meter, which is a footpod monitor. Young healthy individuals (N=20, male n=12, female n=8) completed two 5-min self-paced walks along a trail, and two 5-min trail runs. Reliability of the tasks was determined using Coefficient of Variation (CV), Intraclass Correlation (ICC), and 95% confidence intervals (CI). Measures during trail running that returned a CV less than 10%, met the ICC threshold of 0.70, and displayed good to excellent 95% CI included pace, average elapsed power, average elapsed form power, average elapsed leg spring, and vertical oscillation. The only variable during walking to meet these criteria was maximal power (CV=4.02%, ICC=0.968, CI=0.902, 0.989). Running tasks completed on a trail generally return more consistent measures for variables that can be obtained from the Stryd footpod device than walking tasks.
