Why do some human beings have good chins? Specifically, what makes a good chin?

[punchr]

how is kovalev chin? on /10

7/10 or 8/10

According to LaMotta it's mental if not metaphysical.

The more b*tch in you; the weaker your chin, in laymen terms.

[Dip_Slide]

Is it mental? spiritual?

Think back to the caveman days. Men would bash rocks on each other's skulls and those who had the good chins had a better chance of winning those fights and mating with the females.

But what makes a good chin in the first place?

This sig is extremely distasteful and uncalled for, the man is dead for fücksake!

Grow a pair of balls. Clay was POS.

Idk but this is a good question for some reason all UK fighters have a mediocre to awful chins

Yep.. they seem to have highest percentage guys at world level getting knocked ******ed you

[bojangles1987]

It has very little chance to do with the chin, the neck or the skull.

It's the brain.

Yep. Fighters get stunned or knocked out because they get hit with something that knocks their brain around and ****s with their consciousness. I'd assume pro boxers are among those people whose combination of protections for the brain (cerebral fluid between brain and skull, skull thickness, meninges, and such) secure the brain so it does not get knocked out of place or against the skull as easily as the normal human being.

And certain pro boxers have a better ability to take a punch for the same reason.

Obviously genetics plays a big role, but theres a load more to it than that imo.

They always say that the punch you dont see is the one that knocks you out, so having good eyes, and being able to see and anticipate your opponents attacks is a huge advantage (ie James Toney). If you havent got he reflexes being extremely relaxed (ie the SMW Andrade, Margarito etc) means your head will naturally deflect some the punches power.

Margarito was able to walk through hell vs a slower puncher like Cotto, but when Shane Mosley was smashing him with lightning punches he seemed to get hurt pretty easily. He didnt have time to brace himswlf for the punch or deflect any if the power. Same thing happened in the triangle of fights with Mtagwa vs Gamboa/Lopez.

The guys with poor chins like, say, Amir Khan or David Price, regularly get caught with big shots that they have not seen (both are terrible defensive boxers) and both are extremely stiff.

Lots of the fighters with historically great chins rarely got caught as cleanly as it looks live. They move with the punch at the last second, partly block it etc

If by chin you mean the amount of punishment a fighter can take i.e margarito in Pac fight , then its mental , but if you talk about Pac getting KTFO vs Marquez then its genetic as the guy with the science pictured showed 2 pages ago , his post is correct and explains why we get KO`d.
People confuse chin with punch resilience which are 2 different things , i guess it all depends what you are asking..... , you can take a knee from too much abuse i.e Cotto , it wasn't his chin that failed him in that moment , unlike Pac who just went to another universe due to brain failure.

Its mostly to do with the make up of the cell membrane of you the neurons in your brain.

neurons send signals via something called action potential. This works by having positively charged ions on the outside of the cell and negatively charged ions on the inside, creating a chemoelectrical gradient.

gates in the membrane open when stimulated and this causes the negative ions to rush in and this sends cascading signals down the neuron.



Now, when a hard blow to the head is recieved its beleived that this disrupts the ions and they are thrown out of balance, effecting the abiltiy of the neuron to function. Becuase the membrane is made up of fluid lipids its easy to disrupt it and have these tiny ions move in and out of the cell uncontrolled.



If the right part of the brain is effected, it will cause loss of equilibrium and if the blow is hard enough, the brain will shut down completely as a self defense mechanism to avoid serious damage, which is how you get KOed. The cells can realign the ion gradient using gated ion channles but this takes time and energy which is why being in better shape helps your chin.

As to why some have better chins than others that isnt really known as studies to discover that with any certainty would be unethical. It can be theorised that it would have something to do with number of ions, gated channels, fluidity of the cell membrane, mitochondria in the cells and a number of other factors.

So basically its the like how some people are smarter than others its just the make-up of your brain, and theres not a lot you can do about it, other than be in shape and not drained etc.

By far the best explanation.

To build on this I think legs are also very important in the second phase of brain trauma. So once this process has started and lets say the fighter hasn't been knocked out but his equilibrium has been scrambled, then its very important to have strong legs to survive the moment and/or lessen the effect/obviousness of how hurt you are. Guys with strong legs tend to show out less, and you don't get the bambi leg effect to the same extent.
