Wext, GCw, RPECw, and Recovery at fixed walking speeds. Circles represent PWS and triangles OWS. *Significant difference with PWS (p < 0.05). †Significant difference with OWS for Recovery (p < 0.05). ‡Significant difference with OWS for GCw (p < 0.05). §Significant difference with OWS for RPECw (p < 0.05). GCw, gross energy cost of walking; OWS, optimal walking speed; PWS, preferred walking speed; Recovery, fraction of mechanical energy recovered by the pendular mechanism; RPECw, rated perceived exertion cost of walking; Wext, external mechanical work.
