A
knockout (also referred to as a
K.O.) is a winning criterion in several full-contact combat sports, such as boxing,
kickboxing,
Muay Thai, mixed martial arts and others sports involving
strike (attack). A knockout is usually awarded when one participant is unable to rise from the
canvas within a specified period of time, typically because of fatigue, injury (serious or temporarily incapacitating, e.g. a bleeding cut above the eye can blind a fighter), loss of balance or unconsciousnessA
technical knockout (also referred to as a
T.K.O.) is often declared when the referee or other judges (such as official ring
physician, the fighter himself, or the fighter's cornerman) decide that a fighter cannot continue the match, even though he did not fail the count.Sugar, Bert. Boxing.

United Kingdom records refer to TKOs as either "retired", if the fighter refuses to continue, or "R.S.F.", for Referee Stopped Fight.
Physical characteristics
kickboxer is still knocked down while his adversary is being proclaimed the winnerThere is actually very little known about what exactly causes a knockout but many agree it has to do with minor trauma to the brain stem. This usually happens when the head rotates sharply, often caused by a strike. A common misconception is that a knockout is caused by compression put on the carotid arteries in the neck restricting blood flow, but this is in fact how a choke out works. Margaret Goodman, MD Ringside and training principles URL last accessed
June 20 2006 A basic principle of boxing is to defend against this vulnerability by keeping both hands raised about the face.
If a fighter suffers a concussion and becomes unconscious from a strike (attack) with sufficient knockout power, he or she is referred to as having been
knocked out or
kayoed (
KO'd). Losing balance without losing consciousness is referred to as being
knocked down ("down but not out"). Repeated blows to the head are known to gradually cause permanent
brain damage, with Alzheimer-like symptoms, and in severe cases may cause strokes or paralysis. This is commonly known as becoming "punch-drunk". Because of this, many physicians advise against sports involving knockouts.Lieberman, Abraham. Causing Parkinson: Boxing, Brain Injury.

As a winning outcome
In boxing, a knockout occurs when a fighter is knocked down and does not get up within 10 seconds, as counted by the referee.
In
mixed martial arts, the definitions of knockouts and technical knockouts vary according to organization and jurisdiction. According to its publicized rules, the Japanese
PRIDE FC promotion does not declare 'knockout' as an official type of victory, but rather only technical knockouts when the referee considers a fighter unable to continuePRIDE FC official website. Pride Rules.
