Submission Fighting/ Cage Fighting / Mixed Martial Arts/ Vale Tudo. This sport is a hybrid combination of grappling styles like Pancras, Ju Jitsu, Combat Sombo, Wrestling and Greco Roman combined with the striking style of western boxing and Muay Thai. It arose to world wide fame in the 90's with the emergence of the UFC events. Since then it has travelled to all parts of the world and become as big as Muay Thai and boxing. Sometimes the fights are in rings and other times in the octagonal cage. The rules vary between associations and countries. The instructor at Keddle's Gym is Lee Johnstone who also promotes the Extreme Fighter events and was one of the few pioneers of the mixed martial arts styles in the UK in the nineties. Obviously the styles within the MMA environment all have history but now it has become its own hybrid style. Most of the practioners are from Ju Jitsu backgrounds after the domination of Gracie Ju Jitsu in the early UFC events.
