Optimized, powered ankle exoskeleton assistance can reduce the energy cost of running by 25% wrt zero torque, 15% wrt no exo. Spring-like assistance was ineffective.— Steve Collins (@StevenHCollins) March 25, 2020

Steve Collins , associate professor of mechanical engineering at Stanford and co-author of the research published on Science Robotics, is convinced that experiments of this type are important for a better understanding of the efficiency of the human body in movement. For example, initially, it was assumed that since the legs act like a spring, a support of this type to be most effective; instead, it is motorised which proved successful.
