The purpose of this study was to investigate the changes in muscle activity levels in treadmill running while using wearable resistance as a function of running speed. Nine recreational runners participated in this study; they were requested to perform the running without and with wearable resistance at four discrete speeds ranging from 2.5 to 7.0 m/s on a treadmill. The mass of wearable resistance was set at one third of each participant’s shank and foot mass. Repeated-measures two-way ANOVA analysis was then used to explore the effect of loaded and speed. The data showed that shank loading enlarged the activation amplitude of the biceps femoris (BF) for the concentric action of hip extension following the stretch of knee extension at a high running speed. The loaded condition facilitated the rectus femoris (RF) to be stretched.
