This is from Geoff Thompson's "The Art of Protection" Please read carefully what he says about bracing for a punch. "There are many contributing factors that combine and intermingle to form a knock out on an adversary. The most important factor is not, as you might imagine, a powerful strike, but an accurate one. A powerful attack that is not accurate is very unlikely to knock an adversary out. ...The next most important factor to accuracy in achieving a KO, is deception. The adversary who does not expect the punch cannot prepare for the punch, therefore the impetus of the punch is maximised. To attain a KO you rely heavily on the looseness of the adversarys neck and jaw muscles,if they are not braced when you strike the jaw, a huge shaking of the adversarys brain will occur, it is this shaking of the brain that will cause unconsciousness. If, however, the adversary sees the strike coming, he will brace himself and thereby minimise the shaking, consequently unconsciousness does not occur so readily.
More from Geoff Thompson: "For best effect you should strike anywhere along the line of the jawbone, from the ear to the chin. This, if struck correctly, will cause the brain shaking that brings on unconsciousness. If you strike by the ear this will cause minimal shaking of the brain and a short spell of unconsciousness. The further down the jaw you strike the bigger the brain shake and the larger the probability of unconsciousness; if unconsciousness does occur, the longer the spell of unconsciousness. By the same count, the further down the jaw you strike the smaller the target area becomes. A punch on the point of the jaw will have maximum effect but holds the smallest target. The jawbone, when struck along the jaw line, causes a shaking of the brain. However, when it is struck on the point of the chin the knockout occurs in two phases. First the clivius and the anterior edge of the occipital bone are pushed against the lower portions of the pons and the anterior surface of the medula oblongata. Next, by virtue of the 're-bounding effect', the medula oblongata bounces back against the internal surface of the occipital bone and the posterior edge of the foramen magnum. In essence, the double impact causes the medula oblongata, the most sensitive part of the brain, to concuss, thus causing temporary cancellation of the functions of the central nervous system." ****ing morons. Case closed.
It's clear as day he wasn't faking, the people who say that he was are either haters, on a wind-up or just really do know nothing about the sport
more great info on jaw punches (different source): [url]http://www.livestrong.com/article/25152-punch-jaw-cause-knockout/[/url] Jaw Impact A punch to the jaw causes the head to suddenly spin around. This can be to the left, to the right, or to the back. This quick motion of the skull causes trauma to the brain that leads to a knockout. Points on the jaw that are especially vulnerable to knockouts are the sides of the chin, and where the jaw is attached to the rest of the skull. Acceleration and Deceleration When the jaw is punched, the head quickly accelerates around (CDobler: sound familiar?). After a fraction of a second, it quickly decelerates as muscles, tendons, and bones prevent the head from spinning any further. The brain inside the skull is floating in fluid. It accelerates slower than the rest of the head. This forces it to crash into the inside of the skull when the head stops. Brain Trauma When the brain slams into the inside of the skull, it suffers trauma. It then bounces off the inside of the skull and slams into the opposite side. This causes even more trauma. Depending on the force of the punch, this can happen several times before the brain comes to rest inside the skull. Nervous System Response The trauma to the brain stimulates an overwhelming number of neurotransmitters to fire at the same time. This essentially overloads the nervous system sending it into a state of temporary paralysis. The person who is hit in the jaw loses consciousness and their muscles relax. They fall to the ground with no memory of being hit. Recovery A person who is knocked out by a punch to the jaw suffers a severe concussion. It can take anywhere from several seconds to several minutes to regain consciousness. It all depends on the severity of the brain trauma. In mild cases, the person who is knocked out can shake off the punch with little more than a headache. In severe cases, brain trauma from a knockout punch to the jaw can cause cerebral bleeding and death. It is possible for someone to never wake up from a knockout punch.
The more Dirrell posts you make the more people will watch clips of the "KO". The more people watch the KO the more they will be able to see they were tooled by Andre Dirrell. Keep up the good work :good:yep
Geoff Thompson is pure bad-ass, I read one of his books, don't remember what it's called, but it was all about his career as a bouncer. The cover was him holding brass knucks I think, just a picture of his head. That's a BAAAD man. Honest and likable too.
Case closed? Alot of us already understand the science of the knock out punch, that was never in dispute.. it was the whole "look up with a pissed off look on his face, raise a glove to his head, turn back around and gently lay himself down on the mat and then close his eyes and shake" bit that is a hard sell.
Allow me to quote: "When the brain slams into the inside of the skull, it suffers trauma. It then bounces off the inside of the skull and slams into the opposite side. This causes even more trauma. Depending on the force of the punch, this can happen several times before the brain comes to rest inside the skull." The brain is bouncing all over the place, hitting the skull. This is happening slowly. That's why Dirrell didn't immediately go unconscious -- because his brain was still bouncing all over the place. Why was his brain bouncing so much. See Geoff Thompson quotes above, but basically because the punch was perfectly placed on the jaw, which caused his head to pivot violently and set his brain in motion, like a boat being rocked back and forth by a tide. The debate is over. Where's Pontius Pilate?
