Joint lock in the context of "Karate"

Wrestling is a martial art, combat sport, and form of entertainment that involves grappling with an opponent and striving to obtain a position of advantage through different throws or techniques, within a given ruleset. Wrestling involves different grappling-type techniques, such as clinch fighting, throws and takedowns, joint locks, pins, and other grappling holds. Many different wrestling techniques have been incorporated into martial arts, combat sports, and military systems.

Wrestling comes in different forms, the most popular being professional wrestling, which is a form of athletic theatre. Other legitimate competitive forms include Greco-Roman, freestyle, judo, sambo, folkstyle, catch, shoot, luta livre, submission, sumo, pehlwani, shuai jiao, and more. Wrestling first appeared in the ancient Olympic Games as an event during the 18th Olympiad in 708 BC. There are a wide range of styles with varying rules, with both traditional historic and modern styles. The term "wrestling" in Modern English originated from the late Old English term wræstlunge.

Judo (Japanese: 柔道, Hepburn: Jūdō; lit. 'gentle way') is an unarmed modern Japanese martial art, combat sport, Olympic sport (since 1964), and the most prominent form of jacket wrestling competed internationally. Judo was created in 1882 by Kanō Jigorō (嘉納 治五郎) as an eclectic martial art, distinguishing itself from its predecessors (primarily Tenjin Shinyo-ryu jujutsu and Kitō-ryū jujutsu) due to an emphasis on "randori" (乱取り, lit. 'free sparring') instead of kata (形, kata; pre-arranged forms) alongside its removal of striking and weapon training elements. Judo rose to prominence for its dominance over established jujutsu schools in tournaments hosted by the Tokyo Metropolitan Police Department (警視庁武術大会, Keishicho Bujutsu Taikai), resulting in its adoption as the department's primary martial art. A judo practitioner is called a "judoka" (柔道家, jūdōka), and the judo uniform is called "judogi" (柔道着, jūdōgi; lit. 'judo attire').

The objective of competitive judo is to throw an opponent forcefully onto their backs, immobilize them with a pin, or force an opponent to submit with a joint lock or a choke. While strikes and use of weapons are included in some pre-arranged forms (kata), they are not frequently trained and are illegal in judo competition or free practice. Judo's international governing body is the International Judo Federation, and competitors compete in the international IJF professional circuit.

Catch wrestling (also known as catch-as-catch-can) is an English wrestling style with fewer restrictions than other wrestling styles. It allows techniques using or targeting the legs (unlike Greco-Roman wrestling), it allows joint locks (unlike freestyle wrestling and Greco-Roman wrestling), and there are no mandatory grips. It was spread by wrestlers of travelling funfairs who developed their own submission holds, referred to as "hooks" and "stretches", into their wrestling to increase their effectiveness against their opponents, as well as immigrants through Europe and the Anglosphere.

Catch-as-catch-can was included in the 1904 Olympic Games and continued through the 1936 Games; it had new rules and weight categories introduced similar to other amateur wrestling styles, and dangerous moves – including all submission holds – were banned. At the amateur level, FILA developed and codified new rules and regulations to replace catch wrestling with freestyle wrestling, which was then considered separate from the dangerous, professional catch style. After a revival effort starting in the 1980s, competitive catch wrestling gradually made a return, leading to The Snake Pit's Catch Wrestling World Championships and notable competitions such as the Snake Pit British Championships and ACWA US Open.

An armlock in grappling is a single or double joint lock that hyperextends, hyperflexes or hyperrotates the elbow joint or shoulder joint. An armpit lock can be useful; it will immobilize an opponent and pin them on the ground. An armlock that hyperextends the elbow is known as an armbar, and it includes the traditional armbar (pressing the elbow against the thigh or hips), the shoulder triangle armbar (where a figure-four is locked with the legs), and the shotgun armbar (where the opponent's wrist is placed in the armpit, using the forearm as a fulcrum). An armlock that hyper-rotates the arm is known as an armcoil, and includes the Americana, kimura, and omaplata. Depending on the joint flexibility of a person, armcoils can either hyperrotate only the shoulder joint, only the elbow joint, or both the elbow joint and shoulder joint.

Obtaining an armlock requires effective use of full-body leverage in order to initiate and secure a lock on the targeted arm, while preventing the opponent from escaping the lock. Therefore, performing an armlock is less problematic on the ground, from positions such as the mount, side control, or guard. Armlocks are more difficult to perform when both combatants are standing up, though the stand-up variants are a focus in certain systems such as Chin Na.

Hapkido (UK: /ˌhæpkiːˈdoʊ/ HAP-kee-DOH, US: /hɑːpˈkiːdoʊ/ hahp-KEE-doh, Korean: 합기도; RR: hapgido; pronounced [hap̚.ki.do]), also spelled hap ki do or hapki-do is a Korean martial art. It is a hybrid form of self-defense that employs joint locks, grappling, chokeholds, throwing techniques, kicks, punches, and other striking attacks. It also teaches the use of traditional weapons, including knife, sword, rope, nunchaku (ssang juhl bong), cane (ji pang ee), short stick (dan bong), and middle-length staff (joong bong), gun (analogous to the Japanese jō), and bō (Japanese), which vary in emphasis depending on the particular tradition examined.

Hapkido employs both long-range and close-range fighting techniques, utilizing jumping kicks and percussive hand strikes at longer ranges, and pressure point strikes, joint locks, and throws at closer fighting distances. Hapkido emphasizes circular motion, redirection of force, and control of the opponent. Practitioners seek to gain advantage over their opponents through footwork and body positioning to incorporate the use of leverage, avoiding the use of brute strength against brute strength.

Brazilian jiu-jitsu (Portuguese: jiu-jitsu brasileiro [ʒiw ˈʒitsu bɾaziˈlejɾu, ʒu -]), often abbreviated to BJJ, is a self-defense system, martial art, and combat sport based on grappling, ground fighting, and submission holds. It is primarily a ground-based fighting style and involves taking one's opponent down to the ground, gaining a dominant position, and then using a number of techniques to force them into submission such as joint locks, chokeholds, or compression locks.

Brazilian jiu-jitsu was first developed by the Brazilian brothers Carlos, Oswaldo, Gastão Jr., and Hélio Gracie around 1925, after Carlos was taught jujutsu and catch wrestling in 1917 by either Mitsuyo Maeda, a travelling Japanese judoka, or one of Maeda's students Jacyntho Ferro. Later, the Gracie family developed their own self-defense system that they named Gracie jiu-jitsu. BJJ eventually became a distinct combat sport of its own through innovations and practices, and is considered essential for modern mixed martial arts.

Savate (French pronunciation: [savat]), also known as French Boxing (French: Boxe Française) or French Foot Fighting, is a French hybrid martial art and full-contact combat sport that combines principles of western boxing with a wide variety of kicking techniques. Unlike kickboxing which allow knee and/or shin strikes in competitive bouts, savate involves kicking exclusively with one's feet, but participants can nonetheless target any part of the body. The sport is also notable for requiring footwear to be worn by the competitors, as would be expected from individuals fighting in the streets. A male practitioner of savate is called a "tireur" while a female one is a "tireuse".

Savate de rue (lit. 'street savate'), the term used to differentiate the original martial art meant for self-defense from the subsequent combat sport, is an overarching hand-to-hand combat discipline that incorporates knee and elbow strikes as well as joint locks, sweeps, throws, headbutts and takedowns, in addition to punches and kicks.
