Are some people unable to get the stamina required for boxing despite training hard ?

Yes. Throughout a population you are going to see differing inclinations towards athleticism, not to mention the high bar of mental fortitude that boxing requires. Since you asked specifically about stamina, let's just leave it at that: some people are going to have to work twice as hard to get half the max results. Just the way the cookie happens to crumble.

 

Yeah, what Butt said. Being genetically predisposed to having great stamina is a physical talent, much like running speed, coordination or anything else. You can most certainly improve it, but some a just gifted.

 

we are all genetically different. some hearts and lungs are naturally designed at conception to be more efficient, with higher capacities. its a bell curve between 2 extremes. luck of the draw.

 

Well Shannon Briggs had asthma so by nature his stamina was never going to be peak. Depends where you fight as well, you could be fit where you usually fight and that can change once you fight somewhere High altitude.

 

Just a casual guess but do nerves play into it, my man James Toney was a fat blob but could go 12 rounds all day. Conversely I saw physical specimen Wlad crumble in exhaustion against Brewster....

 

Look at guys like Andy Ruiz and David Tua. They wouldn't win a sprint or a marathon against decent competition but the fact they are relaxed in the ring means they can cruise through 12 rounds of action.

Compare that to an endurance athlete who is anxious about getting hit and switched on at all times. You see it in the crossover boxing events where people from non combat sports fight. Even after months of training they are gassed by the second round because they have no composure in the ring.

 

There's 2 types of stamina as well. People refer to stamina as the ability to go for a long time before getting tired. The other is your ability to recover. If you tire, but recover faster than the average person, you have an advantage.

 

I think this post really knocks it on it's head. Some people get close to having anxiety attacks when fighting. Look at David Price, always looks fit as a fiddle and granted he has a weak chin but he will gas quickly purely from his inability to stay calm. His anxiety cripples him. In the code war heavyweight fight a bit back between Barry Hall and Paul Gallen. Hall is in theory a far superior boxer. However for numerous reasons he got very nervous which in turn gassed him early and it was only 4 rounds of 2 mins.

 

The fighter that I impressed his stamina the most was Julio C. Chavez Sr. His stamina was incredible during his prime. The guy could fight relentlessly from the first bell ring to the final one. Amazing!

 

Johnny Lewis, the aussie trainer out of Sydney, his fighters were always tremendously fit, Jeff Fenech and Jeff Harding especially.

 

Tommy Morrison early in his career would really load up on his punches and seemed very intense. That probably helped to drain his stamina as he was usually blowing up after 3-4 rounds. After the Mercer disaster he seemed to relax a bit more and it helped his stamina somewhat. He was always noted as having stamina issues though and his trainer said he really only trained properly for the fight against Foreman whom he respected and was intimidated by. Being HIV positive most of his career probably didn't help his stamina either.

 

I was going to raise one point but saw this and have to double down SO MUCH on this. There are boxers I've definitely seen "guilty" of this, heaps of it is how they pace themselves and manage themselves in the ring. Oleksander Usyk is a real good example where while his endurance is no doubt exceptional, a lot of it is his calm and picking his moments. He throws a lot of punches where he isn't really forcing the punch out, using some body rotation to get maybe a bit of leverage behind some of them but not heavily committing - doing stuff to keep the other guy busy and land points... but staying loose.

Compare that with a lot of AJ's stuff where he does big tight eye catching jabs and hooks, looks awesome and does the damage when they land but probably take a lot out of it and mean he has to budget them a lot more carefully. He also is quite tense/jumpy when there is return fire, while Usyk moves with and around his opponent - he trusts his ability to keep himself well enoguh out of trouble and doesn't panic, if a shot is coming through he'll work to make sure he doesn't allow a second and maybe will get something back in.... but not push all the buttons on the controller at once.

The other thing is while we aren't in camps to see what the pros do, it seems people do shitloads of cardio but not heaps of aerobic. There is a BIG difference in your endurance and recovery depending on how you train, training more and for longer isn't training better and can really affect things. I feel like I've seen signs of overtraining in some people before fights, often being "off days". Too much intensity training, not enough recovery, and the body never getting to peak correctly.

Could be complete **** but I have definitely felt (at an infinitely lower level) the effects both have had on me when getting more confident in my ability, defnitely the best I'd been at being able to do back to back roundsin the ring was when I had spent a year or so away from fight training and taken up distance trail running, so when I came back I was a bit rusty but still confident in my ability and with more endurance training and an appreciation for the good in not burning energy where it wasn't going to be helpful. Honestly it was massively different from when I was training most nights, not doing specific endurance training, and especially when I was not as comfortable with the idea of being hit

 

A good amount of it just pacing and relaxation. I couldn't run a mile if my life depended on it but I could easily go 4 rounds or grapple for a half hour.

 

This is interesting. I have mostly done weight training.
So boxing is 3 minute rounds, often intense...Why do you think the traditional, less intense aerobics is better overall?
And how do you know when you have done too much cardio?
I have used the terms interchangeably, I see you mean the latter is short, harder work, often intervals.
