Submission wrestling (also known as
submission fighting,
submission grappling,
sport grappling, or simply as
no-) or
combat wrestling (in
Japan), is a formula of competition and a general term for
martial arts and
combat sports that focus on
clinch and
ground fighting with the aim of obtaining a
submission through the use of
submission holds. The term "submission wrestling" usually refers only to the form of competition and training that does not use a
gi, or "combat kimono", of the sort often worn with belts that establish rank by color, though some may use the loose trousers of such a uniform, without the jacket.
