running

forward motion characterized by both feet being simultaneously off the ground surface at a point during the gait cycle (contrast with walking, where one of the feet is always in contact throughout the gait cycle); during running the lower limb adopts a more varus position, the centre of gravity follows a more vertical path, there is greater lower-limb/foot deceleration, and a need for greater shock absorption and propulsive forces than for walking Table 1
