Dressage is a form of horse riding performed in exhibition and competition, as well as an art sometimes pursued solely for the sake of mastery. As an equestrian sport defined by the International Equestrian Federation, dressage is described as "the highest expression of horse training" where "horse and rider are expected to perform from memory a series of predetermined movements".
Horses can use various gaits during locomotion across solid ground, either naturally or as a result of specialized training by humans.
Classical dressage evolved from cavalry movements and training for the battlefield, and has since developed into the competitive dressage seen today. Classical riding is the art of riding in harmony with, rather than against, the horse.
The trot is a two-beat diagonal horse gait where the diagonal pairs of legs move forward at the same time with a moment of suspension between each beat. It has a wide variation in possible speeds, but averages about 13 kilometres per hour (8.1 mph). A very slow trot is sometimes referred to as a jog. An extremely fast trot has no special name, but in harness racing, the trot of a Standardbred is faster than the gallop of the average non-racehorse, and has been clocked at over 30 miles per hour (48 km/h).
The canter and gallop are variations on the fastest gait that can be performed by a horse or other equine. The canter is a controlled three-beat gait, while the gallop is a faster, four-beat variation of the same gait. It is a natural gait possessed by all horses, faster than most horses' trot, or ambling gaits. The gallop is the fastest gait of the horse, averaging about 40 to 48 kilometres per hour. The speed of the canter varies between 16 and 27 kilometres per hour depending on the length of the horse's stride. A variation of the canter, seen in western riding, is called a lope, and is generally quite slow, no more than 13–19 kilometres per hour (8–12 mph).
The airs above the ground or school jumps are a series of higher-level, Haute ecole, classical dressage movements in which the horse leaves the ground. They include the capriole, the courbette, the mezair, the croupade and the levade. None are typically seen in modern competitive dressage. They are performed by horses of various riding academies such as the Spanish Riding School in Vienna and the Cadre Noir in Saumur, and may be seen in other dressage performances. The levade and courbette are a particular feature of the Doma Menorquina, the riding tradition of the island of Menorca. Horses such as the Andalusian, Lusitano, Lipizzan and Menorquín are the breeds most often trained to perform the airs today, in part due to their powerfully conformed hindquarters, which allow them the strength to perform these difficult movements. There were originally seven airs, many of which were used to build into the movements performed today.
Equine conformation evaluates a horse's bone structure, musculature, and its body proportions in relation to each other. Undesirable conformation can limit the ability to perform a specific task. Although there are several faults with universal disadvantages, a horse's conformation is usually judged according to its intended use. Thus "form to function" is one of the first set of traits considered in judging conformation. A horse with poor form for a show jumper could have excellent conformation for a cutting horse or draft horse. Every horse has good and bad points of conformation and many horses excel even with conformation faults.
The passage is a movement seen in upper-level dressage, in which the horse performs a highly elevated and extremely powerful trot. The horse is very collected and moves with great impulsion.
The half-pass is a lateral movement seen in dressage, in which the horse moves forward and sideways at the same time. Unlike the easier leg-yield, the horse is bent in the direction of travel, slightly around the rider's inside leg. The outside hind and forelegs should cross over the inside legs, with the horse's body parallel to the arena wall and his forehand leading. The horse should remain forward, balanced, and bent, moving with cadence. The inside hind leg remains engaged throughout the half-pass, and the horse should not lose its rhythm.
A pirouette is a two-track lateral movement asked of a horse in dressage, in which the animal makes a circle with its front end around a smaller circle made by the hind end. Specifically, the front legs and outside hind leg should travel around the inside hind leg, with the horse remaining slightly bent in the direction of travel. From the part of the rider it needs "much practice in collecting and balancing the horse and in using the aids correctly." The horse may perform the movement at the walk or canter, although the pirouette at the walk is more commonly called the turn on the haunches. It "can also be executed at piaffe."
"Rein-back" is a dressage term to indicate the two-beat movement in which a horse is asked to back up. The horse picks up and sets down its feet almost in diagonal pairs, and moves straight backwards with the line of his forelegs following those of his hind. The horse should remain on the aids during the rein-back.
Turn on the forehand is a lateral movement in equestrian schooling that involves moving the horse's hindquarters around his front legs. Although a basic movement, it is an important training tool for both horse and rider.
A "baucher" is also a type of bit, named after the man.
Riding aids are the cues a rider gives to a horse to communicate what they want the animal to do. Riding aids are broken into the natural aids and the artificial aids.
Lateral movements or lateral flexions within equestrianism, have a specific meaning, used to refer to movements made by a horse where the animal is moving in a direction other than straight forward. They are used both in training and in competition, vary in difficulty, and are used in a progressive manner, according to the training and physical limitations of the animal.
Impulsion is the movement of a horse when it is going forward with controlled power. Related to the concept of collection, impulsion helps a horse effectively use the power in its hindquarters. To achieve impulsion, a horse is not using speed, but muscular control; the horse exhibits a relaxed spinal column, which allows its hindquarters to come well under its body and "engage" so that they can be used in the most effective manner to move the horse forward at any speed.
The turn of the haunches is a lateral movement performed at the halt and walk, used in horse training. It requires the horse, while bent in the direction of the turn, to move his forehand around his hindquarters so that he makes a very small circle with the inside foreleg. The horse should pivot around a hind-leg, as seen in the spin. Additionally, the horse should continue to display basic requirements of dressage, such as an even and regular rhythm, relaxation, acceptance of the aids, balance, and freedom of movement.
Haunches-in, also called travers or tête au mur, is a lateral movement used in the dressage discipline of horse training. It has a close cousin, haunches-out, renvers, or croupe au mur, that is slightly more difficult. Both movements are four-track, meaning they produce four lines of hoof prints in the sand, as opposed to the usual two seen if the horse is straight and to the three-track shoulder-in.
The shoulder-in is a lateral movement in dressage used to supple and balance the horse and encourage use of its hindquarters. It is performed on three tracks, where the horse is bent around the rider's inside leg so that the horse's inside hind leg and outside foreleg travel on the same line. For some authors it is a "key lesson" of dressage, performed on a daily basis.
The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus, which locks major joints in the limbs, allowing horses to remain standing while relaxed or asleep. The limbs play a major part in the movement of the horse, with the legs performing the functions of absorbing impact, bearing weight, and providing thrust. In general, the majority of the weight is borne by the front legs, while the rear legs provide propulsion. The hooves are also important structures, providing support, traction and shock absorption, and containing structures that provide blood flow through the lower leg. As the horse developed as a cursorial animal, with a primary defense mechanism of running over hard ground, its legs evolved to the long, sturdy, light-weight, one-toed form seen today.
