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).
