There is one coach who has broke down exactly why Conor McGregor gases out in fights.

There has been a lot of people who have taken shots at the former UFC lightweight and featherweight champion over his recent antics that put people in jeopardy. This has put his MMA career on the back burner.

It’s well known by now that McGregor and several members of his entourage decided it was a good idea to fly from Ireland to Brooklyn, New York, which is the site of the UFC 223 pay-per-view event on Thursday, April 5, 2018.

McGregor and his crew were let in by members of MacLife and they made their way down to where the buses were.

This is when everything went down as McGregor started throwing trash cans, chairs, barricades and other items at the buses. It was pure chaos, to say the least.

As a result of this incident, it led to three fights being pulled from the card as two fighters suffered injuries. McGregor turned himself into the NYPD following his destruction. Authorities say he’s facing assault charges stemming the incident.

McGregor is no doubt the biggest MMA star in the world right now and some could argue that he’s the most popular fighter that the UFC has ever created. Most fight fans would agree with that assessment.

UFC President Dana White has made it clear in the public that he won’t beg McGregor to make a return to the world famous Octagon.

Make no mistake about it, the UFC President has no concerns about a power struggle with UFC lightweight champion as he works on getting the biggest fighter in the world back in the octagon for his next fight.

There was some speculation that McGregor may fight his arch-rival Nate Diaz for a trilogy fight as both fighters hold a win over each other. That is not the case.

McGregor raised eyebrows last year when he declared he wouldn't return to the UFC unless he’s a co-promoter for the event.

McGregor then fought in a boxing match with Floyd Mayweather. The first boxing match between these fighters took place last August in Las Vegas, Nevada and aired live on PPV (pay-per-view) for the low price of $100 for HD and $90 for SD.

As seen in the fight, the UFC champion did show some good things in the ring considering that it was his first outing as a professional. However, he ultimately lost by TKO in the tenth round.

Georges St-Pierre’s coach, Firas Zahabi told longtime UFC commentator Joe Rogan on his MMA show exactly why McGregor gases out (via Bloody Elbow):

“It think it’s partly genetic,” Zahabi said. “I call it the touch of death. He’s got that left hand, it’s the touch of death. That touch of death comes at a cost. How do you have the touch of death? Where does power come from? Number one on the list, number one, is where your muscle is attached to the bone. It’s genetic. So, Mike Tyson, he has a powerful left hook not because his coach taught him how to hit a left hook.

“He could have hit a left hook like that if he had a mediocre trainer. It has to do with the leverage of his bones,” he continued. “So, for instance, imagine a really heavy pole that weighs a hundred pounds, and I want to stand it up. Well, depending on where I grab it, I’m gonna have more resistance or less resistance. If I grab it near the end, I have more leverage. So where your muscles are attached to the bone is gonna dictate how much leverage you get out of it.”

“If you have a fast-twitch muscle fiber, you can hold less oxygen, but it can twitch faster. Hence the name,” Zahabi explained. “So, if you’re a slow-twitch muscle fiber guy, you can metabolize more oxygen, but you can’t twitch as fast. So, there’s a give and take. So you have a guy like Nick Diaz who needs to knock you out with volume. He can’t knock you out with one shot,” he added. “Look at B.J. Penn. If round one, he doesn’t knock you out, the likelihood of him knocking you out in round two is less. Diaz is the opposite.

“The likelihood of him knocking you out in round three is higher than round one, because of the cumulative attack. McGregor, look at his stats. It’s all round one knockout, round two knockout (using) his fast-twitch, high-leverage left hand. If you take him into deep waters, his fast-twitch muscle fibers cannot metabolize with Mayweather. Mayweather’s so smart, he let McGregor work for three rounds. ’I knew you’re getting excited, keep working. And when you have nothing left, I’m gonna put you out.’ That was such a brilliant strategy.”
