The 2014 JJIF General Assembly voted for the United Society of Jujitsu Organizations to become the USA National Member.
The Duo system has three competition categories: male, female or mixed, and the athletes are judged for their speed, accuracy, control and realism.
It is arguably the most spectacular form of Ju-jitsu competition and it requires great technical preparation, synchronicity and elevated athletic qualities.
Here points are given for immobilisation techniques, controlled strangulations or levers on body joints that bring the opponent to yield.
The ne-waza fight starts in standing position, and the competitors try to gain points with several throwing, take-down and immobilization techniques, sweeps (changing from lower to upper position starting with a guard), or to win the fight ultimately with submission techniques.
