Safeword (sports)
A safeword, as used in sports, is a code word used by a player to avoid impending injury. In certain contact sports, such as rugby and professional wrestling, when a player feels an opposing player's actions will cause the player serious injury, the player may utter a safeword to tell the opponent to stop the actions. Professional rugby union footballers recognize the safeword "neck". A player may say "neck" during a scrum due to fear of a possible neck injury. Players on both teams will recognize this and immediately release any downward pressure. A more common example is "matte" (pronounced "mah-teh", meaning "Wait!") in most Japanese martial arts, including judo, which indicates surrender, usually due to an arm lock or a choke. In professional competition, saying "stop" or "help" does not indicate surrender and the opponent may continue combat. In catch wrestling and early competitive professional wrestling, a wrestler would say "uncle" when put in a submission hold to sig ...

BDSM
BDSM is a variety of often erotic practices or roleplaying involving bondage, discipline, dominance and submission, sadomasochism, and other related interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves to be practising BDSM, inclusion in the BDSM community or subculture often is said to depend on self-identification and shared experience. The initialism ''BDSM'' is first recorded in a Usenet post from 1991, and is interpreted as a combination of the abbreviations B/D (Bondage and Discipline), D/s (Dominance and submission), and S/M (Sadism and Masochism). ''BDSM'' is now used as a catch-all phrase covering a wide range of activities, forms of interpersonal relationships, and distinct subcultures. BDSM communities generally welcome anyone with a non-normative streak who identifies with the community; this may include cross-dressers, body modification enthusiasts, animal roleplayers, rubber fe ...

Injury
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rugby Football
Rugby football is the collective name for the team sports of rugby union and rugby league. Canadian football and, to a lesser extent, American football were once considered forms of rugby football, but are seldom now referred to as such. The governing body of Canadian football, Football Canada, was known as the Canadian Rugby Union as late as 1967, more than fifty years after the sport parted ways with rugby rules. Rugby football started about 1845 at Rugby School in Rugby, Warwickshire, England, although forms of football in which the ball was carried and tossed date to the Middle Ages (see medieval football). Rugby football spread to other Public school (United Kingdom), English public schools in the 19th century and across the British Empire as former pupils continued to play it. Rugby football split into two codes in 1895, when twenty-one clubs from the North of England left the Rugby Football Union to form the Rugby Football League, Northern Rugby Football Union (renamed ...

Professional Wrestling
Professional wrestling is a form of theater that revolves around staged wrestling matches. The mock combat is performed in a ring similar to the kind used in boxing, and the dramatic aspects of pro wrestling may be performed both in the ring or—as in televised wrestling shows—in backstage areas of the venue, in similar form to reality television. Professional wrestling as a form of theater evolved out of the widespread practice of match fixing among wrestlers in the early 20th century. Rather than sanction the wrestlers for their deceit as was done with boxers, the public instead came to see professional wrestling as a performance art rather than a sport. Professional wrestlers responded to the public's attitude by dispensing with verisimilitude in favor of entertainment, adding melodrama and outlandish stuntwork to their performances. Although the mock combat they performed ceased to resemble any authentic wrestling form, the wrestlers nevertheless continued to pr ...

Rugby Union
Rugby union, commonly known simply as rugby, is a close-contact team sport that originated at Rugby School in the first half of the 19th century. One of the two codes of rugby football, it is based on running with the ball in hand. In its most common form, a game is played between two teams of 15 players each, using an oval-shaped ball on a rectangular field called a pitch. The field has H-shaped goalposts at both ends. Rugby union is a popular sport around the world, played by people of all genders, ages and sizes. In 2014, there were more than 6 million people playing worldwide, of whom 2.36 million were registered players. World Rugby, previously called the International Rugby Football Board (IRFB) and the International Rugby Board (IRB), has been the governing body for rugby union since 1886, and currently has 101 countries as full members and 18 associate members. In 1845, the first laws were written by students attending Rugby School; other significant even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrum (rugby Union)
In rugby union a scrum is a means of restarting play after a minor infringement. It involves up to eight players from each team, known as the pack or forward pack, binding together in three rows and interlocking with the three opposing teams front row. At this point the ball is fed into the gap between the two forward packs and they both compete for the ball to win possession. Teams can be penalised for intentionally causing the scrum to collapse, and for not putting the ball into the scrum correctly. A scrum is most commonly awarded when the ball is knocked forward, or passed forward, or when a ball becomes trapped in a ruck or maul. Because of the physical nature of scrums, injuries can occur, especially in the front row. Overview To prepare for a scrum, each team's eight forwards (referred to as the ''pack'' or ''forward pack'') bind together in three rows — the front row, second row and back row. The front row is composed of the two ''props'' and the '' hooker''. To the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Martial Arts
Martial arts are codified systems and traditions of combat practiced for a number of reasons such as self-defense; military and law enforcement applications; combat sport, competition; physical, mental, and spiritual development; entertainment; and the preservation of a nation's intangible cultural heritage. Etymology According to Paul Bowman, the term ''martial arts'' was popularized by mainstream popular culture during the 1960s to 1970s, notably by Hong Kong martial arts films (most famously those of Bruce Lee) during the so-called "chopsocky" wave of the early 1970s. According to John Clements, the term '':wikt:martial art, martial arts'' itself is derived from an older Latin (language), Latin term meaning "arts of Mars (mythology), Mars", the Roman mythology, Roman god of war, and was used to refer to the combat systems of Europe (European martial arts) as early as the 1550s. The term martial science, or martial sciences, was commonly used to refer to the fighting arts of E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judo
is an unarmed gendai budō, modern Japanese martial art, Olympic sport (since 1964), and the most prominent form of jacket wrestling competed internationally.『日本大百科全書』電子版【柔道】(CD-ROM version of Encyclopedia Nipponica, "Judo"). Judo was created in 1882 by Kanō Jigorō () as an eclectic martial art, distinguishing itself from its predecessors (primarily Tenjin Shin'yō-ryū, Tenjin Shinyo-ryu jujutsu and Kitō-ryū jujutsu) due to an emphasis on "randori" (, lit. 'free sparring') instead of "kata" (pre-arranged forms) alongside its removal of striking and weapon training elements. Judo rose to prominence for its dominance over Kodokan–Totsuka rivalry, 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 , and the judo uniform is called . The objective of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arm Lock
An armlock in grappling is a single or double joint lock that hyperextends, hyperflexes or hyperrotates the elbow joint or shoulder joint. An armlock that hyper-extends the arm is known as an armbar, and it includes the traditional armbar, pressing their elbow into your thigh, and the triangle armbar, like a triangle choke, but you press their elbow into your thigh. 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 hyper-rotate only the shoulder joint, only the elbow joint, or both the elbow joint and shoulder joint. Generally, armcoils hurt more than armbars, as they attack several joints at the bone and muscle. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chokehold
A chokehold, choke, stranglehold or, in Judo, shime-waza ( ja, 絞技, translation=constriction technique) is a general term for a grappling hold that critically reduces or prevents either air (choking)''The New Oxford Dictionary of English'' (1999). Oxford University press. . or blood ( strangling) from passing through the neck of an opponent. The restriction may be of one or both and depends on the hold used and the reaction of the victim. While the time it takes for the choke to render an opponent unconscious varies depending on the type of choke, the average across all has been recorded as 9 seconds. The lack of blood or air often leads to unconsciousness or even death if the hold is maintained. Chokeholds are used in martial arts, combat sports, self-defense, law enforcement and in military hand to hand combat applications. They are considered superior to brute-force manual strangling, which generally requires a large disparity in physical strength to be effective.Jones, R ...
