Dynamic, moving bridge
Locomotion modes
Cursorial - running
Arboreal - in trees
Saltatorial - hopping
Fossorial - digging
Aerial – flying
Bipedal – us!
Cursorial
Increasing speed is due to increasing:
1. Stride length - distance between footfalls during a whole stride
and / or
2. Stride frequency - number of strides per unit time
Limb length
Increasing stride length
Posture changes
Drop scapula down to add to limb
length – clavicle becomes reduced
Cursorial stride length
Extension of vertebral column
Cursorial stride length Add a suspension phase to gait
