In martial arts and combat sports, stand-up fighting is hand-to-hand combat between opponents in a standing position, as distinguished from ground fighting. Clinch fighting is stand-up grappling. Fighters employ striking, including striking combinations, using either body parts or mêlée weapons, to incapacitate or injure the opponent. Combattants use blocking techniques to block the opponent's attacks. Martial arts and combat sports that emphasize stand-up fighting include boxing (including bare-knuckle boxing), jōdō, karate, kendo, kickboxing, kung fu, Muay Thai, savate, silat, and Taekwondo.
