This is the first study to characterize the work contributions from
the Foot and Ankle+Foot during running over a long period of
time. Understanding how work is being performed by the
structures of the foot in combination with the shoe can be used to
optimize how these structures are interacting to enhance
performance. Furthermore, the characterization of the
Ankle+Foot can provide design criteria for running prostheses to
enhance running performance for persons with amputation.
