Common Mistakes That Can Cost You Victory In A Jiu-jitsu Competition (and How To Avoid Them)

In high-level Jiu-Jitsu competition, technical skill alone does not guarantee victory. As a referee in major international tournaments and a strength and conditioning coach for elite athletes, I have seen countless talented fighters lose matches—not due to lack of technique, but because of strategic errors, poor mental preparation, or failure to understand the competition system.

As a third-degree black belt, personal trainer, and strength and conditioning expert, I have spent years helping Jiu-Jitsu athletes refine not only their techniques but also their physical preparation and competitive strategy. Since 2017, I have worked as a referee in world-class Jiu-Jitsu competitions, including the World IBJJF Jiu-Jitsu Championship, Master International, and major events organized by Jiu-Jitsu World League, AGF, Grappling Industries, Battleground, and FBMMA.

I have also coached and trained elite competitors, such as Felipe Amorim, Felipe Porto, Nathiely de Jesus (5x IBJJF World Champion), Richar Nogueira (Brazilian, South American, and American Jiu-Jitsu Champion), Leilani Bernales, Alexandre de Jesus "Robinho," and Cláudio Calasans (IBJJF World Champion and ADCC Absolute Champion).

Throughout my career, I have seen many promising athletes fail—not because of lack of talent, but because they made fundamental mistakes in competitions. Winning at the highest levels of Jiu-Jitsu is not just about technique; it is also about strategy, preparation, and execution. Below, I highlight the most common mistakes that cost athletes their matches and, more importantly, how to avoid them.

 

1. Not Knowing the Competition Rules

One of the worst ways to lose a match is due to a lack of knowledge about the rules. Many athletes train hard but do not take the time to understand the specific regulations of the federation in which they will compete. This can lead to penalties, disqualifications, and unnecessary losses.

Common Mistakes:

Illegal Moves – Some competitors attempt techniques that are prohibited for their age or belt level, such as heel hooks for blue belts in certain federations.
Positioning Errors – Athletes deliberately stepping out of bounds to avoid a sweep without realizing this can lead to penalties.
Unawareness of Penalties – Fighters stalling in a position for too long without attacking and ending up penalized for passivity.

How to Avoid Them:

Read the rulebook of the federation in which you are competing.
Attend arbitration seminars – Many event organizers offer courses and updates on rule changes.
Watch competitions and observe how referees apply penalties in real time.

 

2. Not Adapting Gym Jiu-Jitsu to Competition Jiu-Jitsu

The Jiu-Jitsu you practice in the gym does not always translate well to the competitive setting. Many athletes spend hours refining techniques but fail to adjust their game for an environment where time, points, and strategy make all the difference.

Common Mistakes:

Focusing only on submissions without securing points – Ignoring scoring opportunities and going straight for risky submissions without position control. Against a strategic opponent, this can cost the match.
Lack of tactical planning – Entering a match without a clear strategy for different types of opponents (guard players, passers, explosive fighters, defensive players).
Ignoring the importance of advantages – Many athletes overlook advantages and lose due to technical details, failing to realize that a well-structured near attack can determine victory.

How to Avoid Them:

Train match simulations with a scoreboard and timer, improving your ability to manage time effectively.
Study your opponents whenever possible, analyzing their previous fights to understand their style.
Develop a clear game plan for different types of fighters.
Train to accumulate advantages strategically, mastering near-sweeps, near-passes, and well-applied submission attempts.

 

3. Poor Breath Control and Fight Pace Management

Premature fatigue is one of the biggest enemies of a competitor. The adrenaline of a championship can cause many athletes to burn excessive energy in the first minutes, harming their performance for the rest of the match.

Common Mistakes:

Starting too fast – Fighters who go all out in the first few minutes and end up completely exhausted by the end.
Holding their breath when applying force – This increases oxygen consumption and accelerates fatigue.
Failing to adapt to the opponent's pace – An explosive fighter may try to impose a frantic rhythm, while a more technical opponent may slow the pace down. If you don’t adjust, you end up playing their game instead of imposing your own.

How to Avoid Them:

Practice controlled breathing, adjusting your breath to movements and bursts of strength.
Work on fight pace strategies, knowing when to accelerate and when to slow down to recover energy.
Analyze the first seconds of the fight to understand your opponent’s game and adjust your strategy.
Use strong grips and constant pressure to slow down an explosive opponent. If your opponent plays a slow game, increase your movement and grip exchanges to destabilize them.

 

4. Poor Equipment Adjustment and Weight Management Before the Competition

Small details can cost a match before it even starts. A gi rejected during inspection or a mistake on the scale can lead to an unnecessary disqualification.

Common Mistakes:

Gi rejected during inspection – A gi that does not meet competition standards due to collar thickness, sleeve length, or pant fit may result in disqualification.
Misjudging weight measurements – Many athletes fail to check the calibration of the official event scale and only realize they are over the limit at weigh-in.
Poorly managed weight cuts – Last-minute weight cuts can lead to loss of strength, endurance, and, in extreme cases, even fainting before the match.

How to Avoid Them:

Test your gi beforehand – Measure sleeve length, collar, and pants according to the federation’s standards. If possible, bring a backup gi.
Use a reliable and calibrated scale – Compare your scale with the official tournament scale days before the event.
Make gradual weight adjustments, avoiding drastic last-minute cuts that may compromise your performance.

 

Simple Adjustments, Big Results

Competitive Jiu-Jitsu is not just about technique and strength it is also about strategy, intelligence, and preparation. Every detail can influence the outcome of a match, and the mistakes mentioned here are common at all levels, from beginner to black belt.

The next time you step on the mat, ask yourself: Am I just training Jiu-Jitsu, or am I training to compete?

If your answer is the latter, then study the rules, plan your strategy, and pay attention to the details. These small adjustments can be the difference between a frustrating loss and a well-planned victory.
