Muay Thai (Thai: มวยไทย, rtgs: Muai Thai, pronounced [mūa̯j tʰāj] ( listen)) is a combat sport of Thailand that uses stand-up striking along with various clinching techniques. This physical and mental discipline which includes combat on shins is known as “the art of eight limbs” because it is characterized by the combined use of fists, elbows, knees, shins, being associated with a good physical preparation that makes a full-contact fighter very efficient. Muay Thai became widespread internationally in the twentieth century, when practitioners defeated notable practitioners of other martial arts. The professional league is governed by The Professional Boxing Association of Thailand (P.A.T) sanctioned by The Sport Authority of Thailand (S.A.T.), and World Muaythai Federation (WMF) overseas.
