SAWICKI, G.S., C.L. LEWIS, and D.P. FERRIS. It pays to have a spring in Your step. Exerc. Sport Sci. Rev., Vol. 37, No. 3, pp. 130-138, 2009. In humans, a large portion of the mechanical work required for walking comes from muscle-tendons crossing the ankle joint. Elastic energy storage and return in the Achilles tendon during each step enhance the efficiency of ankle muscle-tendon mechanical work far beyond what is possible for work performed by knee and hip joint muscle-tendons.
