擊倒 Knock out（也稱為K.O.）是搏擊運動（像是拳擊、泰拳、綜合格鬥）中的一種勝利判定。當一名參賽者被打倒在擂台上，經過一段規定的時間仍無法站起來，即為擊倒。典型的原因是因為疲勞、受傷（例如臉部上方流血導致選手暫時失明）、失去平衡、失去意識。
技術擊倒（也稱為T.K.O.）是指裁判或醫生判定該名選手無法再繼續比賽，或是選手本身、選手教練決定放棄比賽（通常是丟毛巾進場），即使該名選手並未被打倒在地或是被數完10秒。在某些比賽中，選手被打倒三次也會被判定為技術擊倒[1]在英國則將技術擊倒記錄為「棄權」。
---------------
Knock out (also known as K.O.) is a victory judgment in combat sports (such as boxing, Muay Thai, and MMA). When an entrant is knocked down in the ring, after a certain period of time, he still cannot stand up and is knocked down. The typical cause is fatigue, injury (such as bleeding from the top of the face causing the player to temporarily blind), loss of balance, loss of consciousness.
Technical knockdown (also known as TKO) means that the referee or doctor determines that the player can no longer continue the game, or that the player himself or the player coach decides to abandon the game (usually throwing a towel into the game) even if the player is not knocked down. At the ground or after being counted for 10 seconds. In some competitions, the player is judged to be a technical knockdown when he is defeated three times. [1] In the UK, the technical knockdown is recorded as "abstain".
