Definition of Ground game

Ground fighting (in martial arts sometimes referred to as "ground work" or "ground game") is hand-to-hand combat which takes place while the combatants are on the ground, generally involving a degree of grappling. The term is commonly used in martial arts and combat sports to designate the set of techniques employed by a combatant that is on the ground, as opposed to techniques employed in stand-up fighting. Martial arts and combat sports that emphasize ground fighting include Brazilian Jiu-Jitsu, catch wrestling and mixed martial arts. It is also an important ingredient in judo, sambo and most types of wrestling.
