Conference Paper
Introduction A reduction in gait speed has been associated with many health-related problems in older adults. Importantly, aging is often characterized by a series of biomechanical and neuromuscular alterations, which could increase the energy cost of walking (ECW) and explain, at least partly, the observed reductions in gait speed. However, most o...
