Classic Walking Sequence (IMAGE) University of Utah Caption English photographer Eadweard Muybridge (1830-1904), who pioneered the use of multiple cameras to capture motion, is shown walking heel-first as humans usually do. A new University of Utah study shows that stepping onto the heel first requires much less energy than putting the ball of the foot or the toes onto the ground first.
