BIOMECHANICS

BIOMECHANICS

The walking cycle is divided into the stance (60%) and swing (40%) phases. The stance phase is divided into three intervals: (i) heel strike to foot flat; (ii) foot flat until the body passes over the ankle; and (iii) ankle joint plantarflexion to toe-o ff . During walking up to 12% of the gait cycle is spent with both feet in the stance phase, but with running there is a period when neither foot is in contact with the gr ound – the ‘float’ phase. During running the cycle time is shortened but the forces generated are very much increased. Summary box 41.2 Biomechanics /uni25CF /uni25CF

The gait cycle is divided into swing and stance phases Running generates increased forces, shortens the gait cycle and has a /f_l oat phase when neither foot touches the ground
