Mixed martial arts (MMA) is a full contact combat sport that allows the use of both striking and grappling techniques, both standing and on the ground, including boxing, wrestling, Brazilian jiu-jitsu, muay Thai, kickboxing, taekwondo, karate, judo and other styles. The roots of modern mixed martial arts can be traced back to the ancient Olympics where one of the earliest documented systems of codified full range unarmed combat was utilized in the sport of Pankration. Various mixed style contests took place throughout Europe, Japan and the Pacific Rim during the early 1900s. The combat sport of Vale Tudo that had developed in Brazil from the 1920s was brought to the United States by the Gracie family in 1993 with the founding of the Ultimate Fighting Championship (UFC), which is the largest MMA promotion company worldwide.1
