Kickboxing (/ˈkɪkbɒksɪŋ/ KIK-boks-ing) is a full-contact hybrid martial art and boxing type based on punching and kicking. Kickboxing originated in the 1950s to 1970s.^[2] The fight takes place in a boxing ring, normally with boxing gloves, mouth guards, shorts, and bare feet to favor the use of kicks. Kickboxing is practiced for self-defense, general fitness, or for competition.^[3][4][5] Some styles of kickboxing include: full contact karate, Muay Thai, Japanese kickboxing, Lethwei, Sanda, and Savate.

Although since the dawn of humanity people have faced each other in hand-to-hand combat, the first documentation on the use of kicking and punching in sports combat is from ancient Greece^[1] and ancient India.^[6] But nevertheless, the term kickboxing originated in Japan, in the 1960s, and developed in the late 1950s from karate mixed with boxing, having some influence,^{[7][8][9][10]} with competitions held since then.^{[11][12][13][14]} American kickboxing originated in the 1970s and was brought to prominence in September 1974, when the Professional Karate Association (PKA) held the first World Championships. Historically, kickboxing can be considered a hybrid martial art formed from the combination of elements of various traditional styles. This approach became increasingly popular since the 1970s, and since the 1990s, kickboxing has contributed to the emergence of mixed martial arts via further hybridization with ground fighting techniques from Brazilian jiu-jitsu, and folk wrestling.

There is no single international governing body, although some international governing bodies include the World Association of Kickboxing Organizations (also known as WAKO), World Kickboxing Association, the Professional Kickboxing Association (PKA), International Sport Karate Association, International Kickboxing Federation, and World Kickboxing Network, among others. Consequently, there is no single kickboxing world championship, and champion titles are issued by individual promotions, such as Glory, K-1 and ONE Championship among others. Bouts organized under different governing bodies apply different rules, such as allowing the use of knees or clinching etc.^[15]

The term "kickboxing" (キックボクシング, kikkubokushingu) can be used in a narrow and in a broad sense.

• The narrow use is restricted to the styles that self-identify as kickboxing, i.e., Japanese kickboxing (with its spin-off styles or rules such as shootboxing and K-1), Dutch kickboxing, and American kickboxing.
• In the wider sense, it includes all modern stand-up combat sports that allow both punching and kicking, including those mentioned above, Sanda, Muay Thai, Lethwei, Savate, Adithada, Musti-yuddha, and certain styles of karate (especially full contact karate).

The term itself was introduced in the 1960s as a Japanese anglicism by Japanese boxing promoter Osamu Noguchi^[16] for a hybrid martial art combining Muay Thai and karate which he had introduced in 1958. The term was later also adopted by the American variant. Since there has been a lot of cross-fertilization between these styles, with many practitioners training or competing under the rules of more than one style, the history of the individual styles cannot be seen in isolation from one another.

The French term Boxe pieds-poings (literally "feet-fists-boxing") is also used in the sense of "kickboxing" in the general meaning, including French boxing (Savate) as well as American, Dutch and Japanese kickboxing, and Burmese and Thai boxing, any style of full contact karate, etc.

Arts labelled as kickboxing in the general sense include:

• Japanese kickboxing — combat style created in Japan, and origin of the term "kickboxing".
• Any style of Full contact karate
• Sanda (Chinese kickboxing) — The applicable component of wushu/kung fu of which takedowns and throws are legal in competition as well as all other sorts of striking (use of arms and legs).^[17]
• Shootboxing — A Japanese form of kickboxing which allows throwing and submission while standing, similar to Sanda.
• American kickboxing — a style originating in the United States.
• Dutch Kickboxing — incorporate from three combat arts — Muay Thai, Boxing, and Kyokushin style of Karate.
• French Savate — a historical sport which developed in the 19th century.^[18] It is mostly known for its foot-kicking techniques.
• Ukrainian Combat Hopak is mostly built around punching and kicking techniques.
• Indian Musti yuddha (also known as Muki boxing) and Adithada, a form of kickboxing that uses knee, elbow and forehead strikes in Southern kalaripayattu.
• Korean Kickboxing - Also Known as Kun Gek Do, it's a martial art created in South Korea which is a mixture of Boxing and Taekwondo.^[19]
• The Southeast Asian family of kickboxing sports (also known as the ethnic neutral term of "muay" at the Southeast Asian Games^[20]) including:
  • Thai Muay Boran (Ancient boxing) — Predecessor of Muay Thai, allows the use of headbutts.
  • Thai kickboxing or Muay Thai — a modern Thai martial art that allows punching, kicking, knee and elbow strikes.^[21]
  • Burmese Lethwei — a traditional Burmese martial art of which has now grown into a popular kickboxing event that allows headbutts, knees and elbow strikes. It bears resemblance to neighboring Muay Thai, but Lethwei uses more punches and less kicks.^[22] Head butt, choking and throwing techniques are also used. The fighting intensity and momentum is also considered faster. No boxing gloves are used. There is also no scoring system and knockout is the only way to win a match.
  • Laotian Muay Lao — Laotian boxing which is similar to Muay Thai
  • Filipino Yaw-Yan — Sayaw ng Kamatayan (Dance of Death) is the proper name for Yaw-Yan, a Filipino martial art developed by Napoleon Fernandez. The art resembles Muay Thai in a sense, but differs in the hip torquing motion as well as downward-cutting nature of its kicks and with strong emphasis on delivering attacks from long range.

Since kickboxing is a broad term, understanding the history can be somewhat difficult, since combat is an inherent part of being human. Kicking and punching as an act of human aggression have probably existed throughout the world since prehistory.^[23]

The earliest known depiction of any type of boxing comes from a Sumerian relief in Iraq from the 3rd millennium BC. Forms of kickboxing existed in ancient India. The earliest references to musti-yuddha come from classical Vedic epics such as the Ramayana and Rig Veda, compiled in the middle of the 2nd millennium BC. The Mahabharata describes two combatants boxing with clenched fists and fighting with kicks, finger strikes, knee strikes and headbutts.^[6] Mushti Yuddha has travelled along the Indosphere and has been a preceder and a strong influence in many famous martial arts of Southeast Asia such as Muay Thai and Muay Laos.

In the Pankration, a mixed martial art from ancient Greece, a form of kickboxing was used in its Anō Pankration modality, being able to use any extremity to hit. In addition, it is debated whether kicks were allowed in ancient Greek boxing, and while there is some evidence of kicks,^[24][25][1] this is the subject of debate among scholars.^[26][27]

The French were the first to include boxing gloves into a sport that included kicking and boxing techniques. In 1743, modern boxing gloves were invented by Englishman Jack Broughton.^[28] Frenchman Charles Lecour added English boxing gloves to la boxe française.^[29] Charles Lecour was a pioneer of modern savate or la boxe française. He created a form where both kicking and punching was used.^[30] Lecour was the first to view savate as a sport and self-defense system. The French colonists introduced European boxing gloves into the native Asian martial arts in French Indochina. The use of European boxing gloves spread to neighboring Siam.

It was during the 1950s that a Japanese karateka named Tatsuo Yamada first established an outline of a new sport that combined karate and Muay Thai. This was further explored during the early 1960s, when competitions between karate and Muay Thai began, which allowed for rule modifications to take place. In the middle of the decade, the first events with the term kickboxing were held in Osaka.

By the 1970s and 1980s, kickboxing expanded beyond Japan and had reached North America and Europe. It was during this time that many of the most prominent governing bodies were formed.

• In Japan the sport was widely popular and was regularly broadcast on television before going into a dark period during the 1980s.
• In North America the sport had unclear rules so kickboxing and full contact karate were essentially the same thing.
• In Europe the sport found marginal success but did not thrive until the 1990s.

Since the 1990s kickboxing has been mostly dominated by the Japanese K-1 promotion, with some competition coming from other promotions and mostly pre-existing governing bodies.

Along with the growing popularity in competition, there has been an increased amount of participation and exposure in the mass media, fitness, and self-defense.

On December 20, 1959, a Muay Thai match among Thai fighters was held at Asakusa town hall in Tokyo. Tatsuo Yamada, who established "Nihon Kempo Karate-do", was interested in Muay Thai because he wanted to perform karate matches with full-contact rules since practitioners are not allowed to hit each other directly in karate matches. He had already announced his plan which was named "The draft principles of project of establishment of a new martial art and its industrialization" in November 1959, and he proposed the tentative name of "karate-boxing" for this new art.^[31] It is still unknown whether Nak Muay was invited by Yamada, but it is clear that Yamada was the only karateka who was really interested in Muay Thai. Yamada invited a champion Nak Muay (and formerly his son Kan Yamada's sparring partner), and started studying Muay Thai. At this time, the Thai fighter was taken by Osamu Noguchi who was a promoter of boxing and was also interested in Muay Thai.^[13][32] The Thai fighter's photo was on the magazine "The Primer of Nihon Kempo Karate-do, the first number" which was published by Yamada.

There were "Karate vs. Muay Thai fights" on February 12, 1963. The three karate fighters from Oyama dojo (kyokushin later) went to the Lumpinee Boxing Stadium in Thailand and fought against three Muay Thai fighters. The three kyokushin karate fighters' names are Tadashi Nakamura, Kenji Kurosaki and Akio Fujihira (also known as Noboru Osawa). The Muay Thai team were composed of only one Thai-born fighter.^[33] Japan won by 2–1: Tadashi Nakamura and Akio Fujihira both KOed opponents by punch while Kenji Kurosaki, who fought the Thai, was KOed by elbow. The only Japanese loser Kenji Kurosaki was then a kyokushin instructor rather than a contender and temporarily designated as a substitute for the absent chosen fighter. On June of the same year, karateka and future kickboxer Tadashi Sawamura faced against top Thai fighter Samarn Sor Adisorn, in which Sawamura was knocked down 16 times and defeated.^[33] Sawamura would use what he learned in that fight to incorporate in the evolving kickboxing tournaments.

Noguchi studied Muay Thai and developed a combined martial art which Noguchi named kick boxing, which absorbed and adopted more rules than techniques from Muay Thai. The main techniques of kickboxing are still derived from a form of Japanese full contact karate where kicks to the legs are allowed, kyokushin. In early competitions, throwing and butting were allowed to distinguish it from Muay Thai. This was later repealed. The Kickboxing Association, the first kickboxing sanctioning body, was founded by Osamu Noguchi in 1966 soon after that. Then the first kickboxing event was held in Osaka on April 11, 1966.

Tatsu Yamada died in 1967, but his dojo changed its name to Suginami Gym, and kept sending kickboxers off to support kickboxing.^[34]

Kickboxing boomed and became popular in Japan as it began to be broadcast on TV.^[35] By 1970, kickboxing was telecast in Japan on three different channels three times weekly. The fight cards regularly included bouts between Japanese (kickboxers) and Thai (Muay Thai) boxers. Tadashi Sawamura was an especially popular early kickboxer.^[36][37] In 1971 the All Japan Kickboxing Association (AJKA) was established and it registered approximately 700 kickboxers. The first AJKA Commissioner was Shintaro Ishihara, the longtime Governor of Tokyo. Champions were in each weight division from fly to middle. Longtime Kyokushin practitioner Noboru Osawa won the AJKA bantamweight title, which he held for years. Raymond Edler, an American university student studying at Sophia University in Tokyo, took up kickboxing and won the AJKC middleweight title in 1972; he was the first non-Thai to be officially ranked in the sport of Thai boxing, when in 1972 Rajadamnern ranked him no. 3 in the Middleweight division. Edler defended the All Japan title several times and abandoned it. Other popular champions were Toshio Fujiwara and Mitsuo Shima. Most notably, Fujiwara was the first non-Thai to win an official Thai boxing title, when he defeated his Thai opponent in 1978 at Rajadamnern Stadium winning the lightweight championship bout.

By 1980, due to poor ratings and then infrequent television coverage, the golden-age of kickboxing in Japan was suddenly finished. Kickboxing had not been seen on TV until K-1 was founded in 1993.^[38][39]

In 1993, as Kazuyoshi Ishii (founder of Seidokaikan karate) produced K-1 under special kickboxing rules (no elbow and neck wrestling) in 1993, kickboxing became famous again.^[40][41] In the mid-1980s to early 1990s, before the first k-1, Kazuyoshi Ishii also partook in the formation of glove karate as an amateur sport in Japan. Glove karate is based on knockdown karate rules, but wearing boxing gloves and allowing punches to the head. In effect, it is oriental rules kickboxing with scoring based on knockdowns and aggression rather than the number of hits. As K-1 grew in popularity, Glove karate for a while became the fastest-growing amateur sport in Japan.

Count Dante, Ray Scarica and Maung Gyi held the United States' earliest cross-style full-contact style martial arts tournaments as early as 1962. Between 1970 and 1973 a handful of kickboxing promotions were staged across the US. The first recognized bout of this kind occurred on January 17, 1970, and came about when Joe Lewis, a Shorin Ryu stylist who had also studied Jeet Kune Do with the legendary Bruce Lee, and noted champion in the Karate tournament circuit, grew disillusioned with the point-sparring format and sought to create an event that would allow martial artists to fight to the knock out. Enlisting the help of promoter Lee Faulkner,^[42] training in boxing and combining the techniques of boxing and Karate for the first time in America, Lewis arranged the bout to be held at the 1st Pro Team Karate Championships. Lewis faced Kenpo stylist Greg "Om" Baines,^[43] who had defeated two opponents in years pasts. Lewis won the fight by knockout in the second round. The event was advertised as "Full contact" but the announcers referred to it as Kickboxing, and rules included knees, elbows and sweeps.^[43] Lewis would defend his U.S. Heavyweight champion title 10 times, remaining undefeated until he came back from his retirement. In the early days, the rules were never clear; one of the first tournaments had no weight divisions, and all the competitors fought off until one was left. During this early time, kickboxing and full contact karate are essentially the same sport.

The institutional separation of American full-contact karate from kickboxing occurred with the formation of the Professional Karate Association (PKA) in 1974 and of the World Kickboxing Association (WKA) in 1976. They were the first organised body of martial arts on a global scale to sanction fights, create ranking systems, and institute a development programme.

The International Kickboxing Federation (IKF) and the International Sport Kickboxing Association (ISKA) have been the only organizations to have thrived in the modern era.

The International Kickboxing Federation (IKF) was founded in 1992 by Steve Fossum and Dan Stell. Stell eventually stepped down to go back to fighting while Fossum continued with the organization. In 1999 Fossum and Joe Taylor of Ringside Products created the first amateur open North American tournament for Kickboxing and Muay Thai, now the IKF World Classic.

After ending its venture with K-1 in 2006, ISKA co-operated the World Combat League with Chuck Norris, and Strikeforce MMA in partnership with Silicon Valley Entertainment (SVE), an investor group who also own the San Jose Sharks. Norris passed the WCL to his son-in-law Damien Diciolli in 2007, and it has since become inactive. Strikeforce MMA was sold to UFC in 2011.

The ISKA expanded into sport (tournament) martial arts about 15 years ago,^[when?] and is a co-operator along with WAKO and Global Marketing Ventures (GMV) in the global Open World Tour (OWT) the first worldwide pro circuit of sport karate professional competitors. It sanctions and assists in the annual US Open & ISKA World Championships that anchors the OWT and the North American-based NASKA Tour. The US Open & ISKA World Championships is broadcast live on ESPN2 and ESPN3 each year.

Other kickboxing sanctioning bodies include World Association of Kickboxing Organizations (primarily amateurs) and KICK International.

In West Germany, American-styled kickboxing was promulgated from its inception in the 1970s by Georg F. Bruckner, who in 1976 was the co-founder of the World Association of Kickboxing Organizations. The term "kickboxing" as used in German-speaking Europe is therefore mostly synonymous with American kickboxing. The low-kick and knee techniques allowed in Japanese kickboxing, by contrast, were associated with Muay Thai, and Japanese kickboxing went mostly unnoticed in German-speaking Europe before the launch of K-1 in 1993.

By contrast, in the Netherlands kickboxing was introduced in its Japanese form, by Jan Plas and Thom Harinck who founded NKBB (The Dutch Kickboxing Association) in 1976. Harinck also founded the MTBN (Dutch Muay Thai Association) in 1983, and the WMTA (World Muay Thai Association) and the EMTA (European Muay Thai Association) in 1984. The most prominent kickboxing gyms in the Netherlands, Mejiro Gym, Chakuriki Gym and Golden Glory, were all derived from or were significantly influenced by Japanese kickboxing and kyokushin karate.

Dutch athletes have been very successful in the K-1 competitions. Out of the 19 K-1 World Grand Prix championship titles issued from 1993 to 2012, 15 went to Dutch participants (Peter Aerts, Ernesto Hoost, Remy Bonjasky, Semmy Schilt and Alistair Overeem). The remaining four titles were won by Branko Cikatić of Croatia in 1993, Andy Hug of Switzerland in 1996, Mark Hunt of New Zealand in 2001 and Mirko Filipović of Croatia in 2012.

Some of the top kickboxing promotions in the world are:

• Glory
• K-1
• PKA
• ISKA
• ONE Championship
• Karate Combat
• RISE
• WAKO
• World Kickboxing Network
• Enfusion

Some of the notable kickboxing promoters in the world are:

• Chatri Sityodtong - ONE Championship
• Eduard Irimia - Superkombat
• Kazuyoshi Ishii - K-1
• Pierre Andurand - Glory
• Joe Corley - PKA
• Sadaharu Tanikawa - Fighting and Entertainment Group

Kickboxing has a number of different rulesets. For example, Oriental/K-1 rules allow punches, high and low kicks and even knee strikes, while American kickboxing is limited to punches and kicks only above the belt (high kicks).

In the first two decades of the 21st century, several larger kickboxing promotions such as Glory, One Championship and Bellator Kickboxing have adopted the k1/oriental rule set, which allows knee strikes, kicking and punching.^[44][45][46]

Oriental rules (also known as K-1 rules or unified rules,^[47][48] and sometimes referred to as Japanese kickboxing) was the first combat sport that adopted the name of "kickboxing" in 1966, later termed "Japanese kickboxing" as a retronym.^[12] Since the 1990s, many of the largest kickboxing promotions such as K-1, ONE Championship, Glory and Bellator Kickboxing adopted this ruleset.^{[44][45][46][49]} Oriental rules began to be developed by the Japanese boxing promoter Osamu Noguchi and Karate practitioner Tatsuo Yamada, and it was initially intended as a mix of Karate and Muay Thai,^[50] but it was later affected also by the Dutch rules, which were first formalised in the Netherlands in the 1970s. The primary difference between Muay Thai and Oriental Kickboxing was the prohibition of elbow strikes and throws. In addition, the amount of clinch fighting is drastically decreased. These changes were aimed at reducing injuries and making bouts more accessible to TV viewers. Oriental rules bouts were traditionally fought over 5, 3-minute rounds but 3 round bouts have since become popular. The male kickboxers are bare-chested wearing shorts (although trousers and karate gis have been worn) and protective gear including: mouth-guard, hand-wraps, shin-wraps, 10 oz (280 g) gloves.

• Bouts are 3 to 5 rounds (lasting 3 minutes each) with a 1-minute rest in between rounds.

Gwon Gyokdo, also known as Kun Gek Do and Kyuk Too Ki is a style of Kickboxing from Korea which was founded by Jung Mo-Do. It is a hybrid style which is composed by Taekwondo, Western Boxing and Muay Thai rules and techniques. Korean Kickboxing uses the basic kicking style of Taekwondo, but also adds typical Muay Thai techniques, as well as footwork and dodging tactics of Western Boxing.

Dutch rules (sometimes referred to as Dutch Kickboxing) came about when Japanese kickboxing and Muay Thai were first introduced in Holland in the 1970s. European rules began to be developed by the Netherland Kick Boxing Bond in the 1970s when the late Jan Plas brought the sport from Japan to his native country. The primary difference between Dutch rules and full Muay Thai rules was the prohibition of elbow strikes and the limited knees strikes (only to the body). However, elbows were allowed when both parties agree to it. These changes were aimed at reducing injuries and making bouts more accessible to TV viewers. Like the Thai counterpart, the fights are accompanied with the traditional Thai music during a battle. The Dutch kickboxing rules were instrumental to the development of the K-1 rules.

Punching techniques are very much identical to boxing punches, including

• Jab – straight punch from the front hand. The arm extends from the side of the torso which is quickly turned concurrently with this action. A jab may be directed at an opponent's head or body, and is often used in conjunction with the cross.
• Cross – straight punch from the back hand
• Hook – rounded punch to either the head or body in an arching motion, usually not scored in points scoring
• Uppercut – rising punch striking to the chin
• Backfist usually from the front hand, reverse-back fist and spinning back-fist both usually from the back hand – are strikes to the head, raising the arm and bending the arm at the elbow and then straightening the arm quickly to strike to the side of the head with the rear of the knuckles.
• Flying-punch struck usually from the rear hand, the combatant hops on the front foot, kicking back with the rear foot and simultaneously extending the rear hand as a punch, in the form of "superman" flying through the sky.
• Overhand (overcut or drop) – a semi-circular and vertical punch thrown with the rear hand. It is usually performed when the opponent is bobbing or slipping. The strategic utility of the drop relying on body weight can deliver a great deal of power.
• Bolo punch – a combination of a wide uppercut/right cross/swing that was delivered seemingly from the floor.
• Haymaker - The Haymaker is a wide angle punch similar to a hook, but instead of getting power from body rotation, it gets its power from its large loop. It is considered an unsophisticated punch, and leaves one open to a counter.

The standard kicking techniques are:

• Roundhouse kick or circle kick – Striking with the front of the foot or the shin to the head or the body in a chopping motion
• Front kick or push Kick/high Kick – Striking face or chest on with the balls of the foot
• Side kick – Striking with the heel of the foot with leg parallel to the ground, can be performed to either the head, leg or body
• Semi-circular kick or forty five degree roundhouse kick

There are a large number of special or variant kicking techniques, including spinning kicks, jumping kicks, and other variants such as

• Hook kick (heel kick) – Extending the leg out to the side of the body, and hooking the leg back to strike the head with either the heel or sole
• Crescent kick and forward crescent kick
• Axe kick – is a stomp out kick or axe kick. The stomp kick normally travels downward, striking with the side or base heel (typically the base heel)
• Back kick – is delivered with the base heel of the foot.
• Sweeping – One foot or both feet of an opponent may be swept depending upon their position, balance and strength.

Spinning versions of the back, side, hook and axe kicks can also be performed along with jumping versions of all kicks.

The knee techniques in Japanese kickboxing, indicative of its Muay Thai heritage, are the main difference that separates this style from other kickboxing rules.^[75] See ti khao for details.

• Straight knee (long-range knee kick or front heel kick). This knee strike is delivered with the back or reverse foot against an opponent's stomach, groin, hip or spine an opponent forward by the neck, shoulder or arm.
• Flying knee – can be delivered with the front or back foot. It makes an explosive snap upwards to strike an opponent's face, chin, throat or chest.
• Hook knee – can be delivered with the front or back foot. It makes a half circle spin and strikes the sides of an opponent.
• Side knee – is a highly-deceptive knee technique used in close-range fighting. The knee is lifted to the toes or lifted up, and is snapped to left and right, striking an opponent's sensitive knee joints, insides of thighs, groin.

There are three main defensive positions (guards or styles) used in kickboxing. Within each style, there is considerable variation among fighters, as some fighters may have their guard higher for more head protection while others have their guard lower to provide better protection against body punches. Many fighters vary their defensive style throughout a bout in order to adapt to the situation of the moment, choosing the position best suited to protect them.

• Slip – Slipping rotates the body slightly so that an incoming punch passes harmlessly next to the head. As the opponent's punch arrives, the boxer sharply rotates the hips and shoulders. This turns the chin sideways and allows the punch to "slip" past. Muhammad Ali was famous for extremely fast and close slips.
• Bob and weave – bobbing moves the head laterally and beneath an incoming punch. As the opponent's punch arrives, the kickboxer bends the legs quickly and simultaneously shifts the body either slightly right or left. Once the punch has been evaded, the kickboxer "weaves" back to an upright position, emerging on either the outside or inside of the opponent's still-extended arm. To move outside the opponent's extended arm is called "bobbing to the outside". To move inside the opponent's extended arm is called "bobbing to the inside".
• Blocking – defender's hard blocks to stop a strike in its path so preventing it reaching its target (e.g. the shin block described in more detail below)
• Parry/Block – Parrying or blocking uses the kickboxer's hands as defensive tools to deflect incoming attacks. As the opponent's punch arrives, the boxer delivers a sharp, lateral, open-handed blow to the opponent's wrist or forearm, redirecting the punch.
• The cover-up – Covering up is the last opportunity to avoid an incoming strike to an unprotected face or body. Generally speaking, the hands are held high to protect the head and chin and the forearms are tucked against the torso to impede body shots. When protecting the body, the kickboxer rotates the hips and lets incoming punches "roll" off the guard. To protect the head, the kickboxer presses both fists against the front of the face with the forearms parallel and facing outwards. This type of guard is weak against attacks from below.
• The clinch – Clinching is a form of standing grappling and occurs when the distance between both fighters has closed and straight punches cannot be employed. In this situation, the kickboxer attempts to hold or "tie up" the opponent's hands or enter neck wrestling position. In one way to perform a clinch, the kickboxer loops both hands around the outside of the opponent's shoulders, scooping back under the forearms to grasp the opponent's arms tightly against his own body. In this position, the opponent's arms are pinned and cannot be used to attack. Other forms of clinch involve getting control of opponents neck by collar tie or upper body by underhooks, overhooks and body lock. It is often in the clinch where knee, elbow, sweep and throw techniques are used.

Knocking a person unconscious or even causing a concussion may cause permanent brain damage.^[76] There is no clear division between the force required to knock a person out and the force likely to kill a person.^[77] Also, contact sports, especially combat sports, are directly related to a brain disease called chronic traumatic encephalopathy (CTE). This disease begins to develop during the life of the athlete, and continues to develop even after sports activity has ceased. In addition, repetitive and subconcussive blows to the head, and not just concussions, cause CTE.^{[78][79][80][81][82][83]}
