When the World Champion Leaves on a Stretcher: Notes from the JFKO All Japan 2026

At the 10th JFKO All Japan Full Contact Karate Championship in Tokyo, the reigning WFKO world heavyweight champion entered as top seed and did not make the final four. Yuta Goto was eliminated by ippon in the quarterfinals and carried from the arena. In knockdown karate, a world title is context, not protection.

Shinkyokushinkai claimed nine of the ten available titles across men's and women's divisions. Tatsuya Enda won the heavyweight crown. Tenshin Sawai took the lightweight title for the second time. Three hundred and fifty-four competitors. Two days. No margin for error.

The One-Strike Fight-Ender: What Muay Thai Science Tells Us About Real KO Power

Most fighters assume knockout power is something you either have or you don't. The science says otherwise.

A 2017 biomechanics study recorded elite Muay Thai practitioners generating up to 6,400 Newtons of impact force with the roundhouse kick — at peak foot velocities of 18.3 metres per second, the fastest kick measured across all combat sports. That kind of force doesn't come from raw size. It comes from the efficiency of the kinetic chain, and the kinetic chain is trainable.

On dojoandring.com we break down exactly what builds finishing power in Muay Thai: from hip extension velocity (the single strongest predictor of kick impact force across Muay Thai, karate, and taekwondo) to the strength base that makes explosive output possible, to the accuracy that turns a solid strike into a fight-ending one.

Five training variables. One coherent system. No filler.

When the Score Changes the Mission: The Hidden Structure of Team Kendo

Most people watching a team Kendo match see five consecutive duels. One athlete follows another, the scores accumulate, the team with the most wins takes the encounter.

That reading is not wrong. It is just incomplete.

Underneath the sequence there is a system. Each position carries a specific tactical mission, and that mission is not fixed. It shifts with every result. The Chuken entering with the team two matches down is fighting a completely different battle than the Chuken entering with the team two matches ahead, even if the technique looks identical from the outside.

The full breakdown of all five positions and the logic that connects them is on Dojo and Ring.

The Martial Art the Warsaw Pact Trained With — And Almost Nobody Knows

In 1988, North Korean military instructors traveled to East Germany to teach a combat system most of the world has never heard of. East German airborne troops trained in it. Polish soldiers trained in it. It was called Kyeok Sul Do — or Gjogsul, depending on which side of the Iron Curtain you were on.

This is not a historical curiosity. It is a martial art still practiced today, still tied to the ideology that created it, and still almost entirely opaque to outside observers.

The full analysis, including the only authentic footage released by North Korean state media, is on Dojo and Ring.

The Hidden Reason Fighters Gas Out Before the Final Round

Conditioning matters. But there is a reason some fighters look fresh in the fifth round while others are visibly struggling after the second, even when both have trained equally hard. The answer is not aerobic capacity. It is structural organization, specifically how efficiently a fighter transmits force through the body and returns to a ready position between efforts. Before your next training session, read this. It will change how you watch a fight, and how you prepare for one.

The Fight That Never Happened: Inside the Mayweather-Zambidis Cancellation

The Mayweather-Zambidis exhibition was cancelled days before it was due to take place, brought down by a legal dispute that shut down tickets, promotion, and distribution in one move.

Cambodia Shows Its Hand: A Martial Art the Khmer Rouge Banned Is Now Going Global

On June 27, 2026, four Kun Khmer bouts were broadcast worldwide for the first time from the Kombat Stadium in Phnom Penh.
