The reward for a second win over Briton Dubois is a spot in a really elite membership as a two-time undisputed heavyweight champion.
Solely George Foreman, Evander Holyfield, Lennox Lewis and Muhammad Ali have achieved that feat, however Usyk would be the first to do it within the four-belt period if he’s profitable.
Usyk is not any stranger to going through an opponent for a second time – he has twice crushed Tyson Fury and Anthony Joshua – however his preparations by no means centre across the opponent.
As an alternative, Usyk is put below immense bodily fatigue earlier than being tasked with psychological exams to strengthen his capacity to assume on the spot when he is within the ring.
Throughout robust bodily exercises, Usyk is requested to resolve a Schulte desk, which is a grid crammed with numbers or letters that should be ordered into a particular sequence.
One other activity is juggling balls with the aim of preserving his thoughts centered as he recovers from a interval of cardio coaching.
“We all know all the pieces about Usyk’s physiology and the way his physique works below totally different stresses,” Chycki added.
“We all know how we should always learn his indicators and signs. We did not change something.
“Now we have a spherical desk each Saturday and have a look at what we have finished and what wants to alter. We do not change to the opponents’ technique.”
One of many main well being dangers involved with boxing is power traumatic encephalopathy (CTE) – a mind situation linked to repeated blows to the top and concussion. CTE results in dementia and might solely be identified autopsy.
Chycki instructed one of many causes they monitor Usyk and do cognitive coaching is to assist with the “prevention of mind harm”.
However Dr Thom Wilcockson, a senior lecturer of psychology at Loughborough College, says the scientific proof will not be robust sufficient to recommend cognitive coaching prevents CTE.
“It will add a robustness in opposition to fatigue induced cognitive decline however not essentially the long-term results that CTE may trigger,” he mentioned.
“It will give Usyk a bigger cognitive reserve which could assist mitigate different varieties of dementia like Alzheimer’s illness.”
