The more dangerous Vale Tudo style bouts of the early UFCs were made safer with the implementation of additional rules, leading to the popular regulated form of MMA seen today. Originally promoted as a competition with the intention of finding the most effective martial arts for real unarmed combat situations, competitors were pitted against one another with minimal rules. Later, fighters employed multiple martial arts into their style while promoters adopted additional rules aimed at increasing safety for competitors and to promote mainstream acceptance of the sport. The name mixed martial arts was coined by television critic Howard Rosenberg, in 1993, in his review of UFC 1. Following these changes, the sport has seen increased popularity with a pay per view business that rivals boxing and professional wrestling.
A strike is a directed physical attack with either an inanimate object (such as a weapon) or with a part of the human body intended to cause blunt trauma or penetrating trauma upon an opponent. There are many different varieties of strikes. An attack with the hand closed into a fist is called a punch; an attack with the leg or foot is referred to as a kick; and an attack with the head is called a headbutt. There are also other variations employed in martial arts and combat sports. Buffet or beat refer to repeatedly and violently striking an opponent. Also commonly referred to as a combination, or combo, especially in boxing or fighting video games.
