The fight between Edson Barboza and Shane Burgos at UFC 262 this weekend took a somewhat unusual turn when, after being hit twice by Barboza, Burgos appeared to be well and planning his next strike, before he seemed to have a delayed reaction to his opponent’s successes and shutting down 5 seconds later.
In a new video on his YouTube channel, Dr. Brian Sutterer, an expert in physical medicine and rehabilitation, provides some clarification on what exactly happened during this delay.
“Those punches were certainly hard enough to trigger a knockout,” he says. “But Burgos doesn’t even seem crazy … It doesn’t seem to have affected him at all, until we went down almost 5 seconds later, when he started moving backwards and stumbled, and he finally went down. that concussions can be so complicated, because not everyone responds in exactly the same way. “
Sutterer explains that a concussion occurs when the brain hits the inside of the skull as a result of a sudden impact or trauma, causing a cumulative cascade of events that can lead to loss of consciousness. “Most of the time it happens very quickly,” he says. “A severe delayed response is not so common.”
This cascade includes nerve damage and a massive release of neurotransmitters such as dopamine. And while in many cases the KO may be immediate, there is no single specific medical reason in Burgos to explain the delay or why it took longer to lose consciousness. “An elimination or a concussion is not a‘ boom, it happened ’like a broken bone or a broken ACL,” Sutterer says. “This series of events usually happens faster, but they can be delayed and each case is different.”
“There’s a lot going on in the brain cells, the electrical charges inside those cells, the neurochemicals that send signals back and forth,” he adds. “It’s a complex process in terms of what really happens to the brain when someone is eliminated.”
