GAMMA membership provides a competitive development pathway for participants from the age of eight-years-old upwards, utilising amateur MMA rules modified according to the relative physiological and learning stages of participants’ development and suited to the tournament format.

The foundational level of competition under GAMMA takes place under our member federations at the national or state level for all ages categories. The highest performing athletes may be advanced to continental and world level championships, organised by GAMMA, as part of their national team.

GAMMA organises annual World and Continental Championships on each continent, and creates opportunities for participation in international multi-sport games. Formally recognised in Africa by the African Union (AU), the Association of National Olympic Committees of Africa (ANOCA), the Association of African Sports Confederations (AASC) and the Supreme Council for Sport in Africa (SCSA), GAMMA ushered MMA onto the Olympic platform of the African Games in 2024.

In the senior (18 years+) category, GAMMA allows professional athletes to compete in its international competitions, considering its World Championships to represent the pinnacle of elite, athletic achievement in MMA under amateur, tournament rules.
