The Brazilian Jiu-Jitsu community is mourning the passing of Claudio de Mattos Cardoso, widely known as Caloquinha, who passed away on Christmas Day at the age of 44. A black belt under Vinicius “Draculino” Magalhães, he had been hospitalized at Hospital Vila da Serra in Belo Horizonte while undergoing treatment for lung cancer.
Caloquinha’s impact extended well beyond competition. As a professor and entrepreneur at Gracie Barra BH, he played a central role in the development of Brazilian Jiu-Jitsu in Minas Gerais, overseeing three academies in Belo Horizonte’s Santa Lúcia, Alphaville and Santa Efigênia neighborhoods.
On the mats, his career was marked by consistency and technical precision. He won the Brazilian National Championship, took gold at the South American Championship and earned silver at the World Pro Championship in Abu Dhabi. Competing primarily at lightweight, 167 lbs (75 kg), he was known for his half guard control and a dangerous leg lock game.
His most influential work came as an event organizer. In 2022, Caloquinha founded BJJ Storm, which quickly became one of Brazil’s leading competition circuits. The concept was straightforward, run events that respected athletes and treated them professionally.
In an interview earlier this year, Caloquinha explained his approach.
“The purpose is greater than profit.”
He emphasized doing things from the heart, investing in high-quality medals, championship belts and organizational standards rarely seen in regional tournaments.
BJJ Storm became known for strict punctuality, prize purses exceeding 150,000 reais and operational standards that raised expectations across the scene. He also introduced a ranking system that awarded top athletes in each belt division with travel packages to compete at the IBJJF World Championship in California.
Social work was another pillar of his life. Through the Jiu-Jitsu Consciente project, he worked with underserved communities, including the Morro do Papagaio neighborhood in Belo Horizonte. The initiative went beyond training, offering psychological support, financial education and English classes to help young people build long-term opportunities.
“I want to show the importance of jiu-jitsu in pulling many children away from crime and showing the correct path.”
Tributes poured in following his passing. Five-time IBJJF world champion and ADCC winner Romulo Barral shared photos alongside his longtime friend.
“You will never stop. Eternal love. Until we meet again, my little brother. You were one of the best people I have ever known. Rest in peace.”
Draculino, his longtime coach, published an open letter honoring his student.
“You leave now after doing what you always did, moving forward with courage. Gracie Barra BH today loses one of its greatest heroes and pillars.”
Felipe Preguiça highlighted Caloquinha’s character beyond competition.
“I always admired your truth, something increasingly rare today. A huge heart, many projects, social actions and a genuine desire to help others. I will always remember your kindness, sincerity and the warrior you were at every moment.”
Born July 16, 1981, in Belo Horizonte, Caloquinha began training at 16 after being influenced by his older brother’s involvement in martial arts. His nickname came from his brother’s moniker Caloca, inspired by a childhood resemblance to a cartoon character. Caloquinha roughly translates to Little Caloca.
He trained exclusively under Draculino from the beginning, absorbing both technical instruction and the values of the Gracie Barra lineage. As a purple belt, he began assisting in classes and later became head instructor at Rio Sport Center in Belo Horizonte.
The peak of his competitive career came between 2008 and 2009, when he posted strong results across multiple continents. In 2010, he won the Brazilian Trials for the World Pro Cup, submitting every opponent before reaching the final against Gilbert “Durinho” Burns. That same year, he captured the SP Cup title, finishing all matches by submission and earning an invitation to the World Championships.
Services will be held Friday, December 26, at 2 p.m. at Cemitério e Crematório Bosque da Esperança. He leaves behind family, students and a significant absence in the Minas Gerais jiu-jitsu community.
