Head trainer Rudimar Fedrigo later expanded the program in 1991 to include other aspects of modern mixed martial arts, such as wrestling and submission grappling.

[2] In the 1970s, in search of a more full contact martial art, Taekwondo black belt Nélio "Naja" Borges de Souza [pt] learned Muay Thai and brought it to Brazil.

Coming off of a disappointing five-round decision loss to Tito Ortiz at UFC 25: Ultimate Japan, Silva would return to PRIDE to earn the biggest victory of his career to that point over the Lion's Den's Guy Mezger.

During this span he defeated notable fighters Kazushi Sakuraba (three times), Quinton "Rampage" Jackson (twice), Yuki Kondo, Ikuhisa Minowa, Hidehiko Yoshida, Kiyoshi Tamura, Dan Henderson, Alexander Otsuka, Shungo Oyama, Hiromitsu Kanehara, and would draw with Mirko "Cro Cop" Filipović.

His younger brother Mauricio "Shogun" Rua would also enter the PRIDE fighting championships and would prove the most successful fighter produced by Chute Boxe under Wanderlei Silva's and Ninja's guidance.

Younger than Murilo by about a year and a half, "Shogun" has defeated a who's who list of fighters including Evangelista "Cyborg" Santos, Akira Shoji, Akihiro Gono, Quinton "Rampage" Jackson, Alistair Overeem (twice), Antônio Rogério "Minotouro" Nogueira, Ricardo Arona, Kevin Randleman, Mark Coleman, Chuck Liddell, and Lyoto Machida.

His exciting, fan-friendly style includes much of the standard Chute Boxe Muay Thai clinch work, knees, stomps, and soccer kicks, as well as polished Brazilian Jiu Jitsu.

While there were some tensions between the team, the rivalry was thought ended after a discussion-turned-brawl between Ricardo Arona and Wanderlei Silva at the Tokyo Hilton hotel in the eve of Pride 20 in 2002.

[8] With the demise of PRIDE FC in late 2007, coinciding with the departure of its first mass-appeal superstar Wanderlei Silva around the same time, Chute Boxe entered a new era.

[10] In 2018 UFC fighter Charles "do Bronx" Oliveira joined Chute Boxe Diego Lima in São Paulo[11] starting a 10-fight win streak.
