Union between Martial Arts forces of Brazil and Japan

As we have seen in recent years, many teams, fighters and even training 'camps' expand through alliances aimed at exchange, improvement and various forms of expansion of their teams and activities. On Saturday (04.Sep.2021), two references in martial arts and combat sports sealed a new partnership. The teams of black belts and MMA Champions Carlos Toyota, leader of Carlos Toyota Jiu-Jitsu and Marcelo Barreira, leader of the Barreira Team, started a new phase of projects aimed at the exchange between Brazil and Japan.

Carlos Toyota has an extensive trajectory in MMA having fought important events such as: Deep, Mars, Heat, B-Fight, Fortissimo, Pride Challenge, K-1 Energy, Gladiator, Real Fight, Arzalet, Revolution, Accel, Road FC, Rizin and Ganryujima.

In addition to having a network of affiliated and partner academies in Japan and around the world.

Marcelo Barreira, in turn, also has many years of practice in martial arts and has extensive experience in participating in events and leagues such as: WUFC, Hombres de Honor, XFC, MRWF, Áspera FC, MMA Champions League and Araça FC, in addition to of having ranked among the 16 most voted participants in the 'Global Proving Ground' to participate in the Reality Series “Warrior Island”, in 2013, in the USA.

Barreira has been active in the field of martial arts as a fighter, coach and athlete's agent for many years, with affiliates and partners throughout Latin America and around the world. Among the main Barreira titles we have: WUFC MMA Champion, Hombres de Honor MMA Champion, Araça MMA Champion, MRWF MMA Champion, South American MMA Champion in Odisea Combat, UIAMA World Martial Arts Champion in MMA, Submission and Kickboxing in the years 2005, 2006 and 2017.

The São Paulo native says he is very enthusiastic and happy with this new partnership:

-“I'm a big fan of Japanese MMA, I'm an admirer of Carlos Toyota, who in addition to being a 'thick skin', as everyone knows, is a great master, manager and human being. I've had the opportunity to talk a few times and see about your trajectory. Toyota always helps Brazilians with training and is a 'friendly shoulder', in addition to masterfully carrying the name of our country and I want to be able, together with my students, to help you to continue contributing to the growth of your team and name. I am a great friend and I was a student of Mestre Jailton da Cunha, as well as of his Uncle, the Grão Mestre José Gomes.”-commented Marcelo Barreira.

Responsible for initiating communication between the two MMA Champions, Jailton or “Kaká”, as many call him, boasts the titles of Japanese and Asian Jiu-Jitsu Champion. He is a member of the academy, a professor and a great friend of Mestre Toyota. Jailton has also won countless other Jiu-Jitsu tournaments in “absolute” matches and in his weight class, in addition to accumulating a 2-0 record in MMA.

For those who don't know, Jailton da Cunha is the son of Jaildo Gomes (who was the first teacher of Romero “Jacaré”, founder of Alliance) and nephew of GM José Gomes (brother of the famous Vale Tudo fighter, Ivan Gomes, one of the introducers from Vale Tudo - today MMA - in Japan).

Titãs Fight Communities with MMA, Boxing, Kickboxing, Muay Thai and Jiu-Jitsu fights in Florianópolis - SC

Little by little, we came back to see some movement in the Brazilian MMA scene. Inspired by the MMA events currently held in Japan and in some other countries on the Asian continent - besides the USA, of course - promoters, athletes and coaches promise for August 9th, in Florianópolis-SC, the Titãs Fight Communities, with fights MMA, Boxing, Kickboxing, Muay Thai and Jiu-Jitsu (with and without the gi).

Athletes from the states of Rio Grande do Sul, Paraná and São Paulo have already confirmed their presence on the 'card'. There is still the possibility of including two fighters from Cuba.

The event will take place in the Chico Mendes community, lacking in this type of entertainment and the organizers' intention is to promote sport as a form of social inclusion, in addition to revealing new names for world MMA, like the international fighter Mauricio “Bad Boy”, who still maintains the CT Guetto Diamond Chico Mendes Fight Project. In addition, prosecutors will also collect food for those in need, because while many people are gradually returning to their activities and others remain safe at home, there are thousands on the peripheries who have lost their jobs and are unassisted in many ways.

Titãs Fight Communities - which has the support of community president Chico Mendes Edson Jesus - will be the 1st event to return to Florianópolis after the total stoppage of the city due to the coronavirus pandemic, and it will be done responsibly.

The event can be held with the public and its creators will place the chairs at a safe distance, as part of the necessary safety measures, in addition to requiring the use of masks by sports fans and making alcohol at the box office available to everyone.

According to organizer Thiago Lapolli Fiorenzano da Silveira, also known as “Tubarão”, Titãs Fight Communities has everything to be one of the most beautiful events ever organized in the southern region of Brazil.


The participating athletes agreed to fight for free to promote the sport and are paying for their visits to the competition, as the event is running without financial income, such as tickets or registration, and is entirely dependent on volunteer work and donations of materials. There are already a few supporters.

Still, the organizers need to pay for an ambulance to ensure the fighters' safety, as well as the services of a professional rescuer, renting the octagon, chairs for the public present, purchase of hygiene supplies, among other items.

All this movement is important because it will give opportunity to young people who dream of following the path of sport, because if a child is not guided by the right people from an early age, the whole society may suffer later.

For this reason, the creators of the competition are open to establish partnerships with sponsors who want to link their brand to Titãs Fight and also to the CT Guetto Diamond Chico Mendes Fight Project (social project).

- “And whoever can help with any amount, please contribute to our Vakinha. Don't be ashamed to donate the minimum amount, everything is valuable for the event to exist and many objectives are at stake. Thank you very much. ”- thanks Thiago Lapolli,“ Tubarão ”.

Exclusive interview with Grandmaster João Rezende, Red Belt 9th Degree of Jiu-Jítsu

Today we are going to have a chat with Grandmaster João Rezende de Souza Filho, a follower of Grandmaster Oswaldo Baptista Fadda and one of the pioneers of Jiu-Jítsu and Judo in the Ilhabela Region *, as well as in many regions of Brazil.
Grandmaster João Rezende is originally from the city of Muriqui, in the state of Rio de Janeiro, and is a 9th Degree Red Belt nominated by FJJRio since 2007.
One of the main GMs in the history of Jiu-Jitsu, Grandmaster Rezende has a life of contribution to the Smooth Art.
Throughout his sports career, Grand Master Rezende trained more than 500 black belt athletes, always with the same objective: to train citizens through sport, more precisely through Jiu-Jitsu.
He is the founder, Professor and Master of the PREV Jiu-Jitsu team.

Check out the exclusive interview below:

1) Master, how many years have you been practicing martial arts and what were your original arts?

Grandmaster João Rezende: I started at the age of 7 to practice Judo with Mestre Ricardo Andrade and Jiu-Jítsu with Mestre Olandi Pinto Tavares, the 'Faxada', also responsible for the Police academy under the supervision of GM Osvaldo Fadda. I have been practicing Martial Arts for seventy years and now I am seventy-seven years old.

2) How was your experience of living with Grand Master Fadda? Tell us a little about your migration to the Matriz Fadda academy.

Grand Master João Rezende : I was approximately ten years old, I was already training under the tutelage of GM Osvaldo Fadda, and my previous degrees had been recognized by him. One day, my teacher - GM Olandi Pinto Tavares at the time - arrived and transferred me to the Fadda academy due to the mobility difficulties I had to train Judo and Jiu-Jitsu in different academies. He transferred me to the headquarters so that I could train in a single gym and also have a daily relationship with GM Osvaldo Fadda.

3) Tell us a little about your childhood life and what led you to practice martial arts?

Grand Master João Rezende: Since I was little I was an active boy in a family of fourteen brothers. I always had to defend myself, because the beating ate among the boys, (hahaha), “survival instinct”, I think. I believe that the interest was natural. Once, at the age of 14, I remember that it was my last fight with a brother, I was in great physical shape, training every day. My brother, for a trivial reason, like most fights of teenagers and young people came to attack me and for the simple fact of my avoidance and projection he cut himself at the window of the house, even giving the police (laughs). From then on, my techniques were proven only in the ring and in my defense away from home.

4) Despite being a Fadda, we know that he has a great relationship with members of the Gracie family. Tell us a little about that fact.

Grand Master João Rezende : Firstly, for me the martial art was made for the union and for the evolution of the human being. I don't have, and never had, why I have something against them, who on the contrary, are great friends I have. For ex: I love Robson - "GM Carlos Robson Gracie, President of FJJRio" - I had training experience with great friends Rolker, Royler and Rickson, people I cherish a lot, as well as experience in events from my time with Carlson and Helium, among others.

5) We know that you participated in both Jiu-Jítsu, Vale Tudo, Luta Livre, and Judo competitions as well as in 'Telecatch'. Tell us a little bit about it.

Grand Master João Rezende : There are ... We lived in a time when the sport needed to be publicized and shown to the country and competing in those times was not easy, because "anything went", the aggressiveness was very strong and it was not always possible to give a 'show' as competitions. From there came the idea of ​​'Telecatch', because in addition to showing the techniques, each one had a character. Mine was the “brave cock”.

6) Which sport did you like to play the most?

Grandmaster João Rezende: At the beginning, I liked Judo very much, but after time passed and the rules of Judo became more and more restricted, I joined Jiu-Jítsu and Vale Tudo.

7) Talk about the Jiu-Jítsu vs. rivalry. Wrestling.

Grandmaster João Rezende: I would not say rivalry, as this would denote an enmity, which is unrealistic, as martial arts sports seek the same goals, a healthy body and mind. The desire to dominate others is not part of the philosophy of Jiu-Jitsu. Violence and the intention to inflict damage on anyone, is never done by legitimate members of our group, even when there are extreme tensions, as this is not what is taught in the academies. Fighters with an inclination to violence, homophobia, misogyny, are scolded or expelled from our coexistence. There is no incentive for this behavior.

8) Tell us a little more about your routine during your boyhood at Academia Fadda.

Grand Master João Rezende: Every day I walked approximately 15 km to Bangu Atlético Clube, a place where we trained at the time, times when we trained the physical part and the technical part, and in the physical part we did a lot of training together with Football team, in addition to Jiu-Jitsu.

9) Tell us about some of your achievements as a Master of Jiu-Jitsu, formed black belts, number of students who passed through your team, awards and so on.

Grandmaster João Rezende: First of all, my greatest honor was to have trained great men in different areas of life, as Jiu-Jitsu and martial art as a whole were made for that. After that, I had more than 5 students who passed me in those years, as well as more than five hundred black belts and honor as being the only one in Jiu-Jitsu to have carried the Olympic torch. I received the honorary commendation from Colonel Telhada with GM Otávio de Almeida.

10) Name some black belts that passed through your gym, just a few that you remember at that time.

Grand Master João Rezende: Roberto Penedo de Almeida, Vitor de Paula Souza, Eslim Viana, Giliard Xavier dos Santos, Pablo Rangel, Eber Pires, Fernando Rodrigues Mendes, Daniel Alves de Lucena, Thiago Gaia, Fabricio Medeiros, Ricardo Egídio, Alex Nogueira, Henrique 'Macarrão', Edson Silva, Renato Costa.

11) What were some of the main fighters you saw in your life?

Grandmaster João Rezende: Pedro Hemetério, Shiaki Uchi, Aurélio Miguel, Marco Ruas, Rickson Gracie, Ivan Gomes, Carlson Gracie.

12) To end our chat, what is your life mission?

Grand Master João Rezende : I like to prove that all people are capable, this is the mission. I like to teach respect and that we are all equal and we can get where you want.

22 years of Zenidim Cup of Jiu-Jitsu meets elite of Ponta Grossa, Paraná

One of the only families of fighters in action in MMA today is the city of Ponta Grossa, in the state of Paraná.
Paulo Bueno, Rani "Rex" and Rickson 'The King' are among the biggest finishers of Jiu-Jitsu in MMA alongside the legendary family Gracie, already traditional in this sport.

In a further proof that the family Jiu-Jitsu is the best, Clan Zenidim already adds 35 finalizations in professional MMA, and these victories have occurred in several countries in Latin America.

According to data that were compiled from Sherdog - site that was created by photographer Jeff Sherwood (nicknamed “Sherdog”) in 1997 and later refined with the help of Garrett Poe - Patriarch of Clan Zenidim, fighter Paulão “Imperador ” Bueno and his sons Rani “Rex” and Rickson 'The King' lead in submissions in professional MMA events, whether national or international.

Check out :
Paulão "Emperor" Bueno-10 of his 24 victories came through Jiu-Jitsu.
Rani "Rex" -16 of his 19 wins came through Jiu-Jitsu.
Rickson 'The King'-9 of his 10 victories came through Jiu-Jitsu.

In addition, Rani "Rex" is also considered the greatest finisher of the Campos Gerais region and owner of one of the fastest finalizations in the world in only 14 seconds.

It is easy to remember that Sherdog is the largest international reference in the midst of MMA and famous for keeping the individual records of the fighters, as well as cataloging all the fights held around the world, posting their results in English.

[NE: Sherdog also keeps articles from writers and site staff, exclusive news, interviews, radio shows and hosts 'live' and free MMA events. ]

To win so many victories, the family has always overcome difficulties, such as on Wednesday (30 of January of 2019) when another one of the stages of the CPGMMA (Championship Ponta Grossa de MMA) was celebrated in celebration of the 22 years of Cup Zenidim of Jiu- Jitsu and the 25 years of Paulão Fight.

Due to the bad weather, with lots of rain, many fighters could not attend the event that was held in Zenidim Square (this is the 1 MMA square in Brazil in the region of Jardim Conceição in Ponta Grossa, at the confluence of Avenida Bishop Dom Geraldo Pelanda with Rua Dimas Rudek Potosk).
Even so much of the community participated during the event.

The Ponta Grossa Championship is a seven-month championship. Its main purpose is to keep pace with the competitions of the MMA teams in preparation for national or international events that will take place during the year.
Other objectives of the tournament are to recycle the athletes who are unemployed and reveal new names of the sport in the municipality, besides collaborating with great social campaigns in the region of the Campos Gerais.

This stage of CPGMMA, baptized 22 years of Zenidim Cup of Jiu-Jitsu, brought the best representatives of the Jiu-Jitsu Pontagrossense in MMA, starring balanced struggles and technical level of the Brazilian Jiu-Jitsu elite.

Next Wednesday, 6 of February, we will have another stage of CPGMMA 2019 with the Cup of Falls, again in MMA square, bringing together the best of Judo without a kimono.

Strangulations have the potential to cause brain damage in Jiu-Jitsu and MMA

Last year, a study was published discussing the risk of vertebral artery dissection from strangulation in combat sports. A more recent study of this case was published suggesting that, in addition, repetitive strikes can, in fact, lead to brain damage in Jiu-Jitsu and MMA athletes. According to this study, blows like the rear naked choke and the guillotine have the potential to contribute to the increase of brain injuries in practitioners of both modalities (Jiu-Jitsu and MMA).

The most recent study of this possibility investigated a 40 man who had practiced MMA for a decade. He developed memory problems and other cognitive dysfunctions. Ultimately, he was diagnosed with "chronic traumatic encephalopathy" ("ETC"). The authors were of the opinion that "ETC" was probably caused by the concussive and subconcussive repetitive blows that the patient experienced in MMA, noting that "Our patient had symptoms of 'CTE' secondary to repetitive subconcussive brain injury received during training and competitions."

Interestingly, however, the authors noted that some of the fighter's dysfunctions may be due to repetitive asphyxia during training and Jiu-Jitsu and MMA competitions. The following observations were published:

“What is perhaps little discussed is the role of asphyxia in contributing to long-term behavior and memory changes in the MMA athlete over time. As mentioned, a strangulation (neck submission) is identified as the cause of the stoppage of the fight when a contestant submits to the blow or the referee interrupts the fight, as the afflicted contestant appears to be syncopated or asphyxiated…. In the course of an MMA athlete's career, it is certain that they would experience transient episodes of suffocation several times when participating in fights, or even during training, given the fact that strangulation (neck submission) is a commonly accepted attack. Neurological damage due to compression of the neck could occur. In studies regarding suspension suicide, a force of 2 kg was identified as sufficient to compress the jugular veins to the point of causing cerebral edema, followed by carotid arteries with 5 kg of force, which can cause hypoxic brain damage. Airway compression requires a greater force of about 15 kg, which leads to severe hypoxia and death [28]. Doppler ultrasound reveals that it is possible to completely interrupt the blood flow of the carotid and vertebral arteries in a strangulation (end in the neck), which is characterized by pressure on the sides of the neck [29]. The issue of hypoxic ischemic brain injury ( HI-BI ) may develop in the long term in MMA athletes, as they are subjected to frequent transient asphyxia and strangulation, leading to intermittent hypoxic events in the brain. Common mechanisms involved in the development of hypoxic ischemic brain injury include cardiorespiratory arrest, respiratory failure, and carbon monoxide poisoning. It is also known that about 30% to 60% of patients who develop hypoxic ischemic brain injury as a result of cardiac arrest will develop persistent cognitive, behavioral, and neurological problems [30]. Impaired attention, particularly speed of vigilance and processing, along with memory problems have been observed in survivors with hypoxic ischemic brain injury. In addition, there are also reports of visual spatial dysfunction, apraxia, agnosia and affective and personality changes in patients with hypoxic ischemic brain injury [30]. In our patient, we performed repeated neuropsychological tests, which revealed a decrease in the performance of his attention span and memory over time. There is a possibility that the patient also suffered some degree of hypoxic ischemic brain injury, in addition to the 'ETC', which reduced his general cognitive abilities.”

There is also another comprehensive study entitled "Dangers of Mixed Martial Arts in the Development of Chronic Traumatic Encephalopathy (ETC)" which can be found here.

[NE: Click on the above link or copy and paste into your browser].

In contrast, the MMA community came out in defense of the sport. His arguments are emphatic.
According to them, with the evolution of the rules of MMA, blows such as the kills and the guillotine - despite the great efficiency in the definition of a fight - are techniques that do not cause severe damages to the athlete, even if this one suffers a 'fainting' to the receive such blows.
In addition, it can also be said that the phenomenon of 'blackout' is a form of defense of the organism to reestablish the flow of oxygen to the brain.

It is also necessary to clarify that a blow as a bottleneck would only bring severe damage to a person if it were applied in a long and uninterrupted manner, which does not happen in combat sports with rules, as is the case of MMA, for example. In addition, athletes are highly trained and experienced people, to the point of being able to perceive an impending fainting and interrupt the stroke, even in the absence of the opponent's "three pat" sign of withdrawal.

It is easy to remember-yet-that the referees of the fights should also have the minimum of preparation.

But if you are one of those who remains shocked or believes that fighters might have a more serious problem in the future - despite the arguments cited above - I recommend reading the article "The Risks and Effects of MTA bottlenecks" which was published by Alexandre Matos on the Discovery Channel website, Discovery Channel Brasil.
I also recommend that you regularly read the Science of Struggle column, MMA Brazil website, to keep up to date on this and other topics.

PS: The article that addresses this issue was first published on Combat Sports Law, a blog founded and maintained by Erik Magraken, a contentious lawyer from British Columbia, also a legal counsel for combat sports.

Below: The rear naked choke and the guillotine are the most used submissions to end a fight, according to the UFC Research Institute. Also according to the scientific work released by the UFC, submissions (as well as knockouts) are losing more and more space in MMA. On the other hand, the number of fights that end in points (juries' decision) grows more and more. (Courtesy: LFA media).

Jiu-Jitsu Championship canceled in China after black belt scandal

The land of silk, porcelain, tea, ping pong and logically Kung Fu can also become the land of Jiu-Jitsu soon. Jiu-Jitsu is a sport that has experienced substantial growth in China, albeit in tandem with the popularization of MMA in that Asian country.

Many foreign black belts are helping to sow the seeds of BJJ in the most populous country in the world.

There are Jiu-Jitsu schools in the main cities of Beijing and Shanghai that have been around for years. But most Jiu-Jitsu practitioners in China are still in the early stages of their growth in the sport.

"There are approximately 25 to 30 black bands from Brazil and Japan that are teaching in the largest cities in China. But the first truly Chinese black belt graduated in their own country should be formed in the next few years. " Said Vinz Wong, head of a Jiu-Jitsu academy in Guangzhou City.

The growth of the BJJ in the country can be seen in the tournaments. One of the first performed there had about 50 competitors.
Recently, a major tournament in Hong Kong had more than three hundred competitors, with many brown and black bands from different Asian countries competing in the advanced division.

Some teachers are seeking to introduce jiu-jitsu into elementary schools as a way to further disseminate the modality across the country. Cooperation in bringing Jiu-Jitsu classes to schools may also attract the attention of the students' parents, given the educational factor of the martial arts in training young people.

“Chinese students like to meet at the gym, talk with friends, exchange some martial arts techniques and learn the art of Brazilian Jiu-Jitsu. The culture of the schools is one of less rivalry among students and we are sharing our love for our fellow beings who are still in training through the practice of Jiu-Jitsu”. Complemented Vinz Wong.

However, a recent scandal could "shake" the reputation of 'soft art' in the land of 'Shaolin warrior monks'. The development of the question in particular involves the bureaucratic part.

To better understand the problem, let's turn the globe to complete the way back to Brazil, where it all started.

On 2 in May a blue band from China was awarded an honorary black belt when traveling to Rio de Janeiro.
The newly graduated black belt was also assisting full-time in holding the China Open, a sporting Jiu-Jitsu championship in China under the seal of the IBJJF (International Brazilian Jiu-Jitsu Federation).

The athlete in question was Cui GuoQing (崔国卿), CEO of Shanxi New Culture & Cultural Exchange Ltd. Co. (山西 新 文 源 文化交流有限公司), who received the honorary black belt from the hands of Robson Gracie himself, master belt 9th grade red, pioneer of Jiu-Jitsu in Brazil and second son of Carlos Gracie, the founder of 'Gracie Jiu-Jitsu'.

The honor would have been awarded to the athlete in recognition for his contribution to the promotion and development of the BJJ in China.
In addition to being granted personally to the honorary black belt by Robson Gracie himself, the promotion with the issuance of the certificate also featured the great master red-track Dr. João Carlos Austregésilo of Athayde, a living legend of Jiu-Jitsu. Athayde is an 9 degree graduated by the brothers Gracie, Carlos and Helio.

Also according to some sources, Carlson Gracie Jr. (5th degree black belt) was also present along with some of the Brazilian Jiu-Jitsu practitioners from the old days.
These would be the master Márcio dos Santos (a choral band), Professor Alesandro Nascimento (black belt 5º degree) and Professor Ricardo Cavalcante (also black belt 5º degree), according to the biography of the academy.

As for Mr. Cui, he is very aware of this matter.
His passion to spend millions to allow an IBJJF competition to reach China has its foundation in allowing Brazil's Jiu-Jitsu enthusiasts to advance in the practice and development of their sport and even better by contacting direct with the main entity of promotion of the modality until reaching the technical level to participate of a world-wide competition.

But there was no way and after a planned and well coordinated protest by the Brazilian Jiu-Jitsu community of China, the championship ended up being canceled.

The Chinese BJJ community stays connected online mostly through Wechat, a mobile application that allows users to access news about BJJ events held in different cities across the country.

In turn, the information provided above is from an article published in the Chinese magazine Weixin.
According to another post (although this has not yet been confirmed), the IBJJF would also not be satisfied with Mr. Cui Guoqing's promotion to black belt and therefore would have canceled the IBJJF Open in China.


Has the IBJJF picked up a rope and, from now on, has the China Open been permanently canceled and withdrawn from its calendar by the protests of the Brazilian Chinese Jiu-Jitsu community itself or can the competition still be able to return at a later date?


It's hard to remember that Robson Gracie is the patriarch of the Gracie family and is also the honorary president of the Rio de Janeiro Jiu-Jitsu Federation (FJJERJ), which is the oldest federation of Jiu-Jitsu in the world.
So he does indeed have the powers to bestow the honorary black belt and, for many, the cancellation of the China Open is purely a political matter.

The IBJJF, in turn, has as president Carlos Gracie Júnior, brother of Robson. Its head office is currently in Irvine, California.
He is a red and white belt (8th degree) in Brazilian Jiu-Jitsu.
Carlos Gracie Júnior is also the founder of Gracie Barra, a network of Jiu-Jitsu schools with more than 700 affiliates on six continents.
