Which gaits are characterized by interconnected movement of the hind legs, gut diaphragm, chest, and neck?

The canter and gallop are the gaits characterized by interconnected movement of the hind legs, gut diaphragm, chest, and neck. This coordination is essential for these gaits because they are more dynamic and require a greater range of motion than the walk or trot.

In the canter, the rider experiences a distinct three-beat rhythm, and the horse's body engages significantly, using its hindquarters to push off, while the forelegs reach out in different phases. The gallop further elevates this coordinated movement, showcasing an even more powerful push from the hind legs and a longer stride, emphasizing the engagement of the whole body including the chest and neck as the horse moves forward.

The interconnected movement in these gaits is vital for maintaining balance and propulsion, enabling the horse to cover ground efficiently. This kinetic chain is less pronounced in the walk and trot, which are more diagonal and less forceful in nature. Thus, the canter and gallop uniquely highlight the complex motions of the horse’s anatomy in a way that other gaits do not.
