“…While studies have previously explored how a change in steadystate locomotion speed affects lower-limb joint work and power (Winter, 1983a,b;Ae et al, 1987;Chen et al, 1997;Belli et al, 2002;Teixeira-Salmela et al, 2008;Schache et al, 2011;Farris and Sawicki, 2012a;Pires et al, 2014), no single study has included data for the entire spectrum of speeds that humans can attain. Studies have also quantified the relative contribution from each joint towards the total (sum of hip, knee and ankle) amount of work and power produced by the lower limb during locomotion (TeixeiraSalmela et al, 2008;Rubenson et al, 2011;Farris and Sawicki, 2012a;Stearne et al, 2014); however, locomotion speeds exceeding 4.5 m s −1 have not been considered and some inconsistent results have been reported.…”
