Can muscles tune foot stiffness to enhance efficiency of human locomotion? This project aims to understand the key role that muscles might play in supporting the arch of the foot and determine if this improves the efficiency of human walking and running. The human foot is known to act like a spring to store and return energy during walking and running. The project hypothesises that this function is enhanced by muscular contributions within the foot that act to tune the stiffness of the foot and ....Can muscles tune foot stiffness to enhance efficiency of human locomotion? This project aims to understand the key role that muscles might play in supporting the arch of the foot and determine if this improves the efficiency of human walking and running. The human foot is known to act like a spring to store and return energy during walking and running. The project hypothesises that this function is enhanced by muscular contributions within the foot that act to tune the stiffness of the foot and maximise efficiency of force production. Exploration of how foot stiffness is controlled during human movement is expected to improve our understanding of the evolution of human walking and running and contribute to improving the design of modern footwear.Read moreRead less
