In page Pankration:

"

The athletes engaged in a pankration competition – i.e., the pankratiasts (sg. παγκρατιαστής, pl. παγκρατιασταί[1] – employed a variety of techniques in order to strike their opponent as well as take him to the ground in order to use a submission technique. When the pankratiasts fought standing, the combat was called Anō Pankration (ἄνω παγκράτιον, "upper Pankration");[2] and when they took the fight to the ground, that stage of pankration competition was called Katō pankration (κάτω παγκράτιον, "lower Pankration").[citation needed]
