Walking velocity (m.s^− 1) (mean (SE)) for males and females for each decade across the lifespan. Mean ± SE gait speed (m.s^− 1) is provided for fastest and preferred level, downhill and uphill 10MWT trials separated by sex. * p < 0.05 for males compared with females for fastest speeds in the same decade. † p < 0.05 for males compared with females for preferred speeds in the same decade
