Equestrians' Competition is a sport that involves the skillful riding of horses. It includes two main disciplines: DRESSAGE and POLO. DRESSAGE is a form of riding in which the horse and rider perform a series of predetermined movements, while POLO is a team sport played on horseback in which players use long-handled mallets to hit a ball through a goal. Both disciplines require riders to have excellent control of their horses and to be able to maneuver them with precision.
