Walking
- The walking allow
minimize the cost of locomotion
- Legs moves in pendulum-like swing
- The movement of legs are primary
determined by gravitational force
- Potential and kinetic energies
are continuously exchanged
- Joints of legs can stay
straight and save metabolic cost

- Although walking can save energy
comparing to running, faster walking is less
efficient due to higher oxygen intake than
slower walking.
