Fig. 8. Equine head pitch rotation (solid line) and head vertical translation
(broken line) during representative walk, trot, and canter cycles. Thick
horizontal lines depict support phases for the left hind limb (LH), right hind
limb (RH), left forelimb (LF) and right forelimb (RF). The highly in-phase
relationship depicted in the walk example is characteristic of this gait. By
contrast, the highly out-of-phase relationships depicted in the trot and
gallop examples are common but do not occur consistently (see
Fig. 9).
