How does a fighter rehydrate higher than their 7 day in?

Seriously. Fighters weighing in 3-7 days before fight night, only to rehydrate higher than that... How long are they avoiding food and water? Or are they draining for their check in weights too? Take Brook and Golovkin for example: Brook supposedly weighs 148 a whole week before fight night, despite allegedly being a huge welterweight, but will probably rehydrate to 157ish. Golovkin will weigh 165 or so a week or so out, then rehydrate to 172 (not his last fight). Are they just guzzling water or finally gorging?

Someone cleanse my ignorance.

 

They are bone dry. After the weigh in they fill those muscles up with water

 

I get that, but are they dehydrated the whole week? Or do they cut down a day or two before check in weight, then cut down again for official weight a week later?

 

Its best to start trimming down getting closer and closer to fight weight. You want to do it gradually though sometimes some get the timing wrong and it can have adverse effects. The last week before the event they are not doing any real training, and its to concentrate on weight, recovery to time their peak.

 

However its done it simply cant be good. To work your body on little to no fuel

 

I think they generally do 2 cuts when they have these 7 day weigh in's, obviously the 1st one is a fair bit easier then the 2nd.

Staying low for that long would make your body go catabolic

I said before GGG cuts weight for the 30 day and 7 day weigh in and I was proven right.

The bloke doesn't walk around at 162-165 ffs that is just delusional!

How much do you think GGG weighed vs Jacobs Alex? He was 170 @ the morning weigh in and even an average Joe is heavier at night? I think he was just as big as Jacobs tbh

Brook will be much bigger than 157 on fight night

 

Arturo Gatti once said he didn't drink for several days before a weigh in. HARSH!!! This is a reason why fighters were getting kidney damage on same day weigh ins. If a fighter didn't properly rehydrate his poor ol kidneys had to go into overdrive with little to no fluids in the system.

 

Fighters cut weight for the 7 day weigh-in.

I suspect they use it to make sure they'll be able to make weight on the day.

 

yea but how for example Canelo is able to make 155 lbs catchweight on the day of the weight and then come around 175 lbs on fight night? 20 lbs for one day is LOL.

 

Cutting weight really is a fine art these days, as we all know if done correctly there shouldn't be that many problems but if done incorrectly then it can have serious consequences.

It's about knowing the individuals body and what to do at the right times, for example no fighter would eat after stepping off the scales, it takes time and some rehydration before the digestive enzymes start to work, so it's a specially designed "shake" with salts, sodium, sugar and other ingredients that's needed.

Ideally you need a professional and the reason so many fighters use IV's now is they or there team are not confident they can rehydrate properly orally even though studies have shown if you know how to rehydrate orally then there is no real difference between the two methods.

Using an IV isn't just a case of sticking it in and everything is good. Rehydrating using an IV can be very tricky also, collapsed veins are common and if you over do the IV it can lead to all sorts of problems, for example severe diarrhea.

I'm not any sort of expert but I believe it isn't just a case of avoiding water, it's about cutting calories but also getting the right electrolytes in your body for muscle contraction.

It can be a complicated business but if you know what you're doing then the two weigh ins, especially the first shouldn't be a problem.

I'm sure somebody on here will correct me if I have talked utter rubbish or misunderstood things I have heard and read and I am very happy to be educated on the subject, I find the subject rather interesting (yes I'm that boring).

 

The human body is anything between 50%-70% (ish) water, depending on the individual. There's a lot of wriggle room for cutting on that basis alone (although I take note of the post above). I suspect boxers such as Canelo have a very high water percentage and that allows rehydration to be even more dramatic without serious risk to health.

But it's complex. Muscle is approx 75% water, which I guess is why we feel weak when dehydrated. Get rehydration wrong and it's dangerous as the brain is made up of an even higher percentage of water than body muscle, and this reason alone is why same-day weigh-ins carry a health risk and why the IBF gives 10llbs leeway for the check weight on the morning of the fight.

The IBF live in the real world when it comes to how boxers make weight, they recognise the significance of rehydration and merely ask boxers (and trainers) to keep is sensible.

 

Some people are more talented at weight-cutting than others. Also, being young helps too!

 

I am young too but to gain 10 kilograms for a day is insane

 

In all likelihood they're dehydrated for their 7 day weigh in too.

 

Logically they'd have to be cutting for both the 7 day weigh in and the real thing, maybe using the first as a sort of dry run (pardon the pun). Cutting down to near the fight night weight limit and maintaining that for a week would wreak havoc on your body, and if any fighter states they do that they're either lying or heading for early kidney damage.
