Can somebody explain to me how being weight-drained affects a boxers chin?

[CFH]

For example, whenever people bring up Cotto being badly rocked by Corley and Torres they point to the fact that he was weight-drained from having to make 140. I don't doubt that this could be true, but I have never seen convincing evidence presented as to how it would affect his chin. Is it just something as simple as the fact that being dehydrated etc. would make a person more prone to passing out/dizziness? I can easily understand it eroding a fighters resistance to body punches, but how does it affect a fighters ability to take head shots?

weight drained can be a factor as so to speak in the manner of upseting your system by not eating solid foods for upto 3 days for some guys and taking a limited amount of liquids which will weaken a fighter and lessen there reflexs and decrese the stamina in turn they may not see in coming punches as well as they norm do...........the classic case of " the punch you dont see is the one that gets you" some boxer can do it better then others..........bottomline it doesnt give you a weaker chin just tires you quicker which lowers your ability to take punches

I would kind of see it like taking a punch first thing in the morning right after you wake up and eat breakfast as opposed to that same punch later on in the afternoon after being at work all day right before dinner after not having lunch.

When a fighter is weight-drained, the water that would normally protect the brain is no longer there. Therefore the brain is bashed about which could lead to brain damage. The effect of a punch on the chin is also much greater as the brain is bashed around much more when it has no water surrounding it.

That's a very simple way of explaining it.

ono correct, plus you are more likely to get hit, it affects the muscle nuerons and eyesight.

Thats why the weigh in is 24hrs before a fight ,it allows the fighters to rehydrate their bodies before going into combat.

That's what I assumed, but no one ever spelled it out for me before. Thanks.

Erik Morales is a good example too. He was well known to have a granite chin. But that chin slowly deterioted when he started having some weight issues.
