Poland's Tomasz Zakolski, Giannis Ballas of Greece and Fabio Carril of Portugal ran the event which attracted 75 people from six different countries.

Three languages were used during the seminar - English, French and Portuguese.

It was divided into two parts, with Ballas first presenting on body movement, timing, distance and competition scenario training.

He also covered solo, one-on-one and one-on-two drills, mixing technical ability with fun and playful approaches.

A student of Ballas then presented two techniques, one for passing guard position and the second a sweep from the bottom position.

It is hoped that the seminar - the first of three - will help spread ju-jitsu in African countries.

The fighting system of ju-jitsu splits combat into three different parts.

In part one, athletes are involved in distant combat with their arms and legs, including kicks and punches.

Once a strike has been made, the bout enters into part two.

Fighters then try to bring each other down with various throwing techniques, with points awarded for how effective the manoeuvres are.

Once on the floor, the fight can enter the third stage.

Points are given here for submission techniques which cause an opponent to yield.

The winner is the athlete who gains the most points from the duration of the fight.

If a fighter performs a perfect technique in all three parts, they win automatically by ippon.

Example of moves registering ippon include an unblocked punch or kick, a perfect throw or takedown or forcing your opponent to tap out to a submission move.
