The term vaulting horse may also be used literally. There is an offshoot of equestrianism which uses a specially trained live horse. Competitors perform a one to two minute dance/gymnastics routine on the back of their horses either solo or in pairs or trios. This is an adaptation of the horseback performers you may have seen at the circus.
