Mixed Martial Arts, or MMA, is a full-contact combat sport that combines various techniques from different martial arts disciplines. Fighters use striking and grappling skills, allowing them to compete in a variety of ways, including punches, kicks, and submissions. MMA competitions are typically held in an octagonal cage, known as the Octagon, where fighters face off under a set of rules that ensure safety and fairness. Organizations like the UFC (Ultimate Fighting Championship) have popularized the sport, showcasing athletes from around the world and drawing large audiences.
