The UFC is the premiere Mixed Martial Arts (MMA) organization in North America, and probably the world. It held its first show in 1993, and is now selling out arenas around the world.
Mixed Martial Arts is a martial arts combat sport that allows for striking (punches, kicks, knees, elbows) and grappling (throws, takedowns, joint locks, chokes, pinning, transitions). Small, open-fingered gloves are usually worn. Generally, strikes are allowed on the feet and on the ground, although the type of ground strike that is legal varies between countries and organizations. Common fouls include head butts, small joint manipulation (twisting the fingers and toes), attacks to the groin, spine, and back of the head, pulling the hair, and scratching or twisting the skin. The action may take place in a cage or a ring; the UFC prefers to use an octagonal cage.
The UFC operates under the Unified Rules, which have been adopted by most US states. Under these rules, it's illegal to kick, stomp, or knee the head of an opponent who isn't standing. The fighters are also restricted to wearing, in addition to protective equipment (mouth guard, groin protector, gloves), only fight shorts, so wrestling shoes, head gear, shin guards, or traditional martial arts uniforms are not allowed. It should be noted that many UFC fighters make their way to the cage wearing traditional martial arts uniforms in order to pay tribute to their background or their teachers, but strip down to just fight shorts before the fight begins.
The UFC has five weight classes: Heavyweight (265lb limit), Light Heavyweight (205lbs), Middleweight (185lbs), Welterweight (170lbs), and Lightweight (155lbs). Other organizations will feature lighter weight classes, different weight classes entirely, and women's matches (also separated by weight division).
