The decision to stop it is yours

Everything else on this site describes what a fighter does in the final days.

This describes what the person watching him is responsible for, and it comes down to one decision that almost nobody prepares to make.

The case that changed the rules in some places

In November and December 1997, three American collegiate wrestlers died within about a month of each other. All three had been restricting food and fluid while exercising in vapour-impermeable suits in hot environments.

The response in the United States was structural: weigh-ins in high school and collegiate wrestling moved to 1 or 2 hours before competition, minimum weight programmes based on body composition, and hydration testing as part of certification.

Reform has since travelled further than it once had. United World Wrestling and the International Judo Federation both run competition-day morning weigh-ins for the same reason.

Where it has not travelled is professional boxing and the major MMA promotions, where day-before weigh-ins and a full recovery window remain standard, and where the conditions that produced those deaths remain available.

If your athlete competes under a day-before system, the rules are not going to stop him. You are the check.

The mechanism that actually kills

Worth understanding, because the signs make sense once you know it and look like ordinary fatigue if you do not.

Intense exercise damages muscle, which releases myoglobin into the bloodstream. In volume, myoglobin is toxic to the kidneys. A dehydrated kidney has less fluid available to clear it.

So the two problems multiply rather than add. That is exertional rhabdomyolysis, and it is the process documented in the 1997 deaths and in published fatal weight-cut cases in combat sport since.

The signs the corner should know

Observable without equipment, and they mean stop rather than push.

• Muscle cramps that will not release.
• Pain in the calves, lower back or jaw that does not match what the athlete has been doing.
• Jaw clamping involuntarily, as distinct from jaw ache. That is a sign of serious electrolyte disturbance rather than of effort.
• Resting heart rate substantially above his own baseline, in the region of 20 beats or more.
• Nausea, vomiting, or an inability to keep fluids down.
• Skin that is hot and dry during sauna or suit work. When sweating stops, thermoregulation is failing, and that is a heat stroke sign.
• Confusion, disorientation or a personality change that the people who know him would notice.
• Brown or cola-coloured urine together with muscle pain.

That last combination is the rhabdomyolysis pattern. It is an emergency department, not a decision to make in a corridor, and not something to reassess in an hour.

What to do while waiting for help

This part is where well-meaning staff cause harm, so I will be exact.

If there is any suspicion of heat illness, cool him actively while you wait. Get him out of the heat and out of the suit, ice or cold wet towels to the neck, armpits and groin where large vessels run close to the surface, and keep going until help arrives.

Cooling is the intervention that changes outcomes in heat stroke, and the time spent waiting without doing it is the time that matters.

Oral rehydration solution belongs in the bag for the athlete who is tired, thirsty and lucid. It has no role in the one who is not.

Why the decision has to exist before the week

The practical problem is not medical.

By Thursday evening the athlete has done 8 weeks of work, the family has travelled, the opponent is confirmed, and everybody in the room has something invested.

That is the worst possible moment to make a judgement call about somebody's kidneys, and it is exactly when the call arrives.

A staff that has not decided in advance will decide under those conditions, and the decision will be worse.

So write it down before the camp starts. Not as a philosophy, as a list: which signs end the cut regardless of what is at stake, who has the authority to say so, and what happens next.

Naming a person matters more than the list. A staff where everybody assumes somebody else will call it is a staff where nobody does.

Who should hold it

Not the head coach, if the club has any alternative.

The head coach has the strongest investment in the athlete competing, and asking him to be the person who stops it is asking him to be two things at once.

A doctor if you have one. A designated welfare officer if you do not. In a small club, the person whose job it is on that day, named in advance, and understood by the athlete before the week begins.

The public case for naming that person in advance is Max Holloway in 2018: the call to stop his six-day cut was made on weigh-in morning by a commission doctor, because nobody inside the camp had been given it. The case study.

The athlete knowing who holds it is part of the protection. It gives him somebody to tell.

And if you are the only coach

Most clubs do not have a doctor, a welfare officer or a second senior staff member. Telling a single coach to delegate the decision is advice he cannot use.

Three things work in that situation, and none of them require another salary.

Write the criteria before the camp and give a copy to the athlete. If the rule exists on paper, agreed weeks earlier, you are not making a judgement on Thursday night. You are applying something you both signed up to. That removes most of the conflict of interest without removing you.

Name somebody outside the gym. A parent for a junior, a spouse, a training partner from another club, a physiotherapist you use occasionally. Somebody who will take a call and whose only stake is the athlete. The requirement is not authority, it is distance.

Use an instrument. A urine refractometer costs less than a pair of gloves and converts a judgement into a reading, which is much harder to argue with at 11 at night. The hydration testing page covers what the number means and what it does not.

The point of a named third person was never the person. It was removing the decision from the moment. A written rule and a number on a device do the same job in a club of one.

And the hardest part: he will not tell you

An athlete 4 days into a cut is not a reliable narrator about his own condition, and the reasons are not character failings.

He has been taught that this is what it feels like. He has done it before and survived it. He does not want to be the reason the thing is called off. And cognitively he is not at his sharpest, which is a documented effect of the state rather than an accusation.

A staff relying on the athlete to raise a problem has no system at all.

A minimum standard for the last 3 days

A club doing those four things has removed most of the circumstances in which people have died, and none of them cost anything.

The conversation when you pull somebody

How it is handled decides whether the athlete ever tells anybody anything again.

Say what you saw rather than what you concluded. He is not being accused of weakness, he is being removed from a situation you assessed.

Do it privately if the situation allows and immediately if it does not. Safety beats dignity when they conflict, and they rarely do.

Make the reason structural rather than personal. The rule existed before this week, it applies to everybody, and it was not written about him.

An athlete who is pulled and treated as having failed will hide the signs next time. An athlete who is pulled and treated as having been protected by a system will report earlier.

What happens afterwards

He needs a medical review before returning, particularly if any of the rhabdomyolysis signs were present. Not optional, and not a judgement about how bad it was.

And the staff needs to look at why it got there. A cut that had to be stopped was either too large, started too late, or run without adequate monitoring, and all three are staff decisions rather than athlete failures.

If the answer is that he was in the wrong weight class, that is the finding, and it changes next season rather than being noted and repeated.

Somebody in the room has to be it

In the systems that reformed, the rules do most of the work. In professional boxing and MMA they do not.

The athlete will not stop it. The head coach is the least suitable person to stop it.

Which leaves a decision that has to be assigned in advance, to a named person, with written criteria, before anybody has anything invested in the answer.
