About Muay Thai
Muay thai is Thailand's national combat sport and a direct descendant of the older muay boran systems that served the army. The shift to its present form came in the early twentieth century: a ring, boxing gloves, weight classes and timed rounds were introduced, and the rope hand wraps disappeared. The nickname "the art of eight limbs" describes it exactly. Alongside fists and feet, elbows and knees are used in full, which is the fundamental difference from kickboxing — and with them the clinch, in which the opponent is held by the neck and worked with knees. The clinch is characteristic of the Thai style and is broken up under many other rulesets. Training rests on repeating a small number of techniques to perfection: shin kicks on pads, bag work, clinch and sparring. The signature technique is the shin kick delivered with the whole hip rather than the instep, so much of the work goes into conditioning and timing. A bout is preceded by the ritual dance wai kru ram muay, in which the fighter honours his teacher. The competitive base in Thailand runs deep: professionals start as children and have hundreds of fights behind them before reaching the big Bangkok stadiums. In Europe muay thai is widely available and serves both as a sport in its own right and as the standard striking component of MMA preparation.
History
Muay Thai derives from the older Thai art muay, today called muay boran, which also included holds and ground fighting. The attribute Thai was added at the start of the 20th century to distinguish it from Western boxing. A written mention of Thai wrestling is already contained in the palm-leaf manuscript of the Mungrai law from 1296. It received its modern form in the twenties and thirties of the 20th century. The first permanent ring was built in 1921 at Suan Kulap, and under King Rama VII (1925–1935) referees, timed rounds and, after a death in the ring, boxing gloves instead of hemp rope wrappings were added. Rajadamnern Stadium opened in 1945, Lumpinee in 1956. IFMA held the first World Championships in 1993 with participants from 20 countries, and the IOC recognised it provisionally in 2016 and fully on 10 June 2021.
Technique
Muay Thai is called the art of eight limbs: fists, elbows, knees and shins. Under the IFMA rules, punches, elbows, knees and kicks to the head, trunk and legs score if they hit an unblocked target, a hit on the glove, forearm or shin does not count. The clinch is allowed, and a distinction is made between the arm clinch, the side clinch, the low clinch and the so-called swan neck. The referee breaks it with the command yaek. Prohibited are groin strikes (low blow), strikes to the ankle and to the back of the head, and intentional headbutts. Elbows are allowed, and we have not found any special technique bans for younger categories in the IFMA rules. The related Burmese lethwei is described as the art of nine limbs, the ninth being the head. Since 1986, Thailand × Myanmar bare-knuckle shows have been held at Songkran, the Thai side fighting under the old rules including headbutts and throws.
Training
Training consists of many rounds of 3–5 minutes with a break usually of 1–2 minutes: running, shadow boxing, skipping rope, bodyweight exercises, medicine ball and above all work on Thai and boxing pads. Resistance is trained on pads, in the clinch and in sparring. We have not been able to document what share of a session is sparring. A Polish study (Sieńko-Awierianów et al., 2016) of 40 practitioners from one club reports training injuries in 55% of respondents, with contusions predominating. The most commonly affected were the thighs and lower legs (19.3%), knees (18.1%) and head (13.3%).
Ranks and progression
Muay Thai has no unified system of grades, and we have not been able to document minimum times between grades or mutual recognition of grades between federations. Some schools, mainly outside Thailand, mark grade with coloured armbands (pra jiad). Anderson Silva, the former UFC middleweight champion, has a black pra jiad, for example. Traditionally the trainer hands the fighter the mongkhon headband when he judges him ready to represent the gym in the ring. Level is otherwise measured by bouts and titles. The title belts of Lumpinee Stadium are awarded in weights from mini flyweight (105 pounds) to super welterweight (154 pounds).
Who it suits
The IFMA has youth categories from 10 years (10–11, 12–13, 14–15 and 16–17 years), an under-23 category and seniors from 17 to 40, and its rules have no veteran categories. Women compete in the same weights and under the same rules as men. At Lumpinee Stadium a boxer older than 15 may fight, and at Rajadamnern Stadium the first women’s bouts took place in 2022. According to The Nation, the Thai boxing law of 1999 sets an age over 15 for Muay Thai, yet younger children also fight. According to the Bangkok Post, boxers under 15 in a Ramathibodi Hospital study had an IQ about 10 points below the norm. A study of 195 fighters reports an injury in the last bout in 55.4% of them, mainly to the limbs (58%), and concussion was reported by 5.4% of fighters.
Competition
An IFMA senior bout has three rounds of three minutes, and youth have shorter rounds (ages 10–11 3 × 1 minute, ages 14–15 3 × 2 minutes). Senior men and women compete in 13 weight classes from 45 to 91+ kg. Scoring uses the ten-point system, judged by three or five judges. After a knockdown the referee must count to eight, and a third knockdown in a round ends the bout. After a knockout there are at least 30 days without a bout, and after three knockouts within a year 12 months. Professional bouts at Lumpinee Stadium have at most five rounds of three minutes with a two-minute break. IFMA also lists Muay Boran / Mae Mai Muaythai as a medal discipline. Muay Thai is on the programme of the World Games and the European Games, but is not yet an Olympic sport.
Gear
For IFMA competition, gloves of 10 ounces (284 g), a groin guard, a mouthguard, shin and elbow guards and a helmet without face and chin protection are compulsory. The fighter enters in a red or blue shirt. A trunk protector is worn by youth and the under-23 category, it is forbidden for senior men, and senior women have a chest protector. At Lumpinee Stadium fighters box in gloves of 8 or 10 ounces depending on weight.
Philosophy
Before a bout the fighter performs wai khru ram muay (wai greeting, khru teacher, ram dance), a ritual dance of respect for the teacher, parents and ancestors. Under IFMA rules it lasts at most two minutes and contains at least three bows. The ram muay is personal and often reveals who trained the fighter. The mongkhon headband is worn into the ring as a tribute to the gym, and the pra jiad armbands. The referee’s commands are Thai: yoot (stop), yaek (break) and chok (box). In Thailand 17 March is celebrated as Muay Thai Day after the legend of Nai Khanom Tom, which historians regard rather as a myth that arose in the 20th century.
Styles and schools
The older Thai art of muay boran had, according to the Siam Society, three main regional styles, summed up in the saying "heavy fist of Korat, cunning of Lopburi, graceful of Chaiya". The Korat style from the northeast is known for a precise, powerful short-range kick and swinging strikes, with the front foot firm and the rear one on the toes. Lopburi is associated with straight strikes and tactical dexterity, including hidden movements. Chaiya from the south uses tight, compact movement in a low, balanced stance in which every joint serves as both weapon and defense. The Siam Society also names the traditional schools Muay Chaiya Ban Khru Praeng, the school of master Tui in Korat and Muay Tha Sao Phraya Phichai.

Today's competitive muay thai under the IFMA distinguishes three forms: full contact, half contact (Muaythai Technical) and no contact. The medal disciplines also include the ritual wai kru and the performance of mai muay, both of which were recognized at the 2025 Asian Youth Games. A special discipline is Muay Talay, in which fighters box on a floating 4 × 4 m platform on the surface of a pool, and whoever falls into the water loses. Children aged 10 to 11 may not attack the head in it. Classical mae mai techniques, such as the flying knee or the spinning elbow, are according to a Vice report performed today mainly in muay boran demonstrations, and few try them in the ring.
Today
Amateur Muay Thai is governed by IFMA, and the professional sector by the World Muaythai Council. The WMC was created in 1995 by a resolution of the Thai parliament and merged with IFMA in 2019. IFMA became a member of GAISF in 2006 and of IWGA in 2013. Professional bouts in Thailand are governed by the Thai boxing association. ONE Championship has separate rules for Muay Thai with 4 oz gloves and has also held events at Lumpinee Stadium since 2023.

At the 2023 SEA Games in Cambodia the discipline was called Kun Khmer, and Thai athletes boycotted it. At a press conference on 9 February 2023, IFMA stated that it has no dispute with Kun Khmer and that Kun Khmer is not recognised in the Olympic movement. Muay Thai also stood at the beginnings of Japanese kickboxing. At Lumpinee Stadium three kyokushin karateka faced Thai boxers, and sources give February 1964 or 12 February 1963. The result was 2:1 for kyokushin, and Kenji Kurosaki lost by an elbow knockout. In 1969 Kurosaki then founded Mejiro Gym, from which Toshio Fujiwara in 1978 became the first foreigner to win a Rajadamnern Stadium title. In 1991 Ramon Dekkers defeated Superlek Sorn-esan in Thailand. After losses in Thailand, Dutch gyms increased their emphasis on the clinch, elbows and knees. Muay Thai also spread into MMA. In Curitiba, Brazil, Rudimar Fedrigo, a student of Nélio Borges de Souza, who had learned Muay Thai in Thailand, founded the Chute Boxe school in 1978. UFC champions Mauricio Rua and Anderson Silva came out of the academy.
In culture
According to Britannica, muay thai is the national sport of Thailand, and fights are accompanied at ringside by loud betting by spectators. Every fight has live music, and according to the International Centre for Martial Arts at UNESCO the ensemble plays oboe, cymbals and drums. A pi muay band also accompanied the wai kru and mai muay demonstrations at the 2025 Asian Youth Games. On 26 March 2024 the Thai government approved a proposal that the Ministry of Culture submit muay thai for inscription on the UNESCO list of intangible cultural heritage. The Thai embassy in Manila recalls the legend of Nai Khanom Tom, who as a prisoner in Burma in 1774 defeated ten Burmese fighters and won his freedom. According to the embassy, since 1923 fighters have been required to box in gloves and with a groin guard instead of rope wraps. The film that made muay thai famous was Ong-Bak of 2003 by director Prachya Pinkaew, the first major role of Tony Jaa. A critic of The New York Times, according to the NZIFF festival, stressed that the action scenes were created without wires or tricks.
Did you know
Muay thai was part of the Southeast Asian Games in 1995 and of the Asian Games in 1998 as a demonstration sport, and in 1999 the Olympic Council of Asia recognized it. It became a full medal discipline at the 2017 World Games in Wrocław and at the 2023 European Games in Poland. It received provisional IOC recognition on 6 December 2016, and in the same year the IFMA signed a memorandum with UNESCO. Under IFMA rules, a fighter may exceed his category at the weigh-in by at most five percent, otherwise he is disqualified. In a close round, factors such as exhaustion, bruises, willingness to lead the fight, defense and the style of muay thai decide. According to a 2015 Vice report, the Lumpinee and Rajadamnern stadiums paid a bonus of 10,000 baht for a knockout by a head kick and 20,000 baht for a knockout by a flying knee or spinning elbow. The International Centre for Martial Arts at UNESCO lists among related arts the Indian musti-yuddha, Lao muay lao, Burmese lethwei, Cambodian pradal serey and Malay tomoi.
