When people say boxer A has a good chin but had no business at that weight etc. Obviously as a rule the bigger the weight the bigger the punches But what's the science behind the bigger you are the better chin you have? Punch resistance is not affiliated with size and muscles or is it?
Well for one, when you're dehydrated, you have a lower volume of cerebral fluid surrounding your brain, because it is depleted of water. Guys who cut too much weight and go into a fight dehydrated are much more prone to being knocked out; your cerebral fluid is the slowest to rehydrate as well. There were other factors, but one of the main reasons Foreman's chin was so much better in his second career was because he was properly hydrated. He had an idiotic trainer who used to dehydrate him for fights, believing it to be an advantage (this was before much of the known science on brain injury) so his stamina and chin were SUBSTANTIALLY WORSE. Despite being much older, the hydration factor was one of the main reasons his chin was so drastically improved. As far as punch resistance and muscles, I've never bought that argument. Guys like Hagler and Tyson had super thick trapezius (neck) muscles, while guys like Margarito and McCullough had thin necks. Hagler and Holyfield have thick skulls and round heads, while Margarito for instance has a long slender head. I'd say it's genetics and hydration mostly, because all arguments related to physical specifications don't seem to hold, since people possessing all different characteristics have had iron chins and bad chins! There isn't one specific physical characteristic of any iron chinned fighters that empirically shows anything really, iron chins come in all shapes and sizes. The only aspect I've seen that reliably has shown to make a difference is the hydration factor, and guys cutting too much weight. There is ample proof both in real life scenarios and scientifically to demonstrate dehydration lowers your cerebral fluid protecting your brain, making you prone to being knocked out. Oh and there is no science behind the bigger you are, the better chin you have, that isn't true. You're judged off your ability to take punches from people in your weight class, so it's relative to your division. LaMotta, McCullough, McCall, Margarito etc. these are all guys considered to have some of the greatest chins ever, and they come from all different weight classes.
:good I understand not cutting weight properly does you no good in that department. But say if iron chinnedMathysse was to move up and fight heavy hitting GGG would his chin hold out or are you only iron chinned relative to your weight class?
I edited my post, read the rest of it now. When a guy who is dehydrating too much goes up to a more normal weight class, his chin will usually improve, good example of that was Miguel Cotto. He has never been iron chinned, but his chin at LWW was pretty bad, because he has a stocky build and was having to kill himself to make weight. Once he went up to WW, he had a respectable chin. If a guy is already iron chinned, and comfortable at a weight, usually their chin will suffer when they move up, but not always. It depends on their body type and such, if they have room to properly grow, and if they rush jumping weights or not. A guy like James Toney is a SMW fighting at Heavyweight, yet has never been knocked out. My point being is that there is no absolutes, there are cases for everything, everyone is different. :good:good
What does getting his chest hit by a baseball bat have to do with his chin? His friend should of cracked his chin with the bat instead...
