2. locomotor functions; 4가지
1) a propulsive force is generated (propulsion)
2) upright stability is maintained, despite an ever-changing posture (stance stability)
3) the shock of floor impact at the onset of each stride is minimized (shock absorption)
4) energy is conserved by these functions being performed in a manner that reduces the amount of muscular effort required (energy conservation)

1) standing stability
