About the year 1990, three styles were famous for their effectiveness in the competitions of the mixed martial arts: the wrestling, the Brazilian jiu-jitsu, and Muay Thai. This can be because of their attention given to the combat by means of holds. Before the year 1990, the promoters organized a lacking amount of the competitions of the mixed martial arts, and some martial arts base on blows. Therefore, probably, most instructors of these arts had given too little attention to the holds.
