[1][2] The Federation of Guanabara was chaired by Hélio Gracie and had sports bases, regulations, etc.
The foundation of the Federation was the first step to make the Jiu-Jitsu a sport and not a street fighting art.
The orders of belt rank tracks were regulated: white, blue, purple, brown, and black.
In the rules, maneuvers like takedowns, mount with both knees on the floor or back with hooks award the competitor points.
