Martial arts
Martial arts are codified systems and traditions of combat. They are practiced for a number of reasons ranging from; violent street fighting, self-defense, military and law enforcement; to non-violent exercising, ceremonial, competition; physical, mental, and spiritual development; entertainment; and to preserve the intangible cultural heritage of a nation. The term "martial arts" was originally used to refer to the traditions of East Asia, but has subsequently been applied to other practices which originated outside that region.
