I know heavyweights can go on longer than other weights I would say 32-36 for a big heavyweight and 26-34 for a small heavyweight I mean on average, I'm not speaking for everyone
There is no definitive answer to this. Some peak early, and some peak later. Generally speaking almost every heavyweight starts declining at the age of 35 or even earlier (in this case if he has a unhealthy lifestyle, if he stopped training properly or if he had too many wars/injuries earlier in his career). If I had to pick a prime "age" for heavyweights, it would be from 30-33. It is the best combination of fight experience and physical abilities.
That's tough...Iron Mike was around 21, Larry Holmes about 30. I'll go out on a limb and say 24 or so, on average...knowing there are tons of exceptions.
Depends on who you ask. According to Tyson fans, a HW can be past his prime and washed up at 23, not even old enough to have a high school reunion. Marciano fans will tell you Walcott was prime and aged like wine at 38. Wladmir fans will tell you he wasn't in his prime when he lost to Sanders despite being a 26 year old world champion with 41 fights. Frazier fans might say he was washed up when he lost his title at 29 despite being undefeated. Funny how that works.
It seems to depend on a multitude of factors. Genetics, ring wars, gym wars, substance abuse, food abuse, fighting style, height, etc.
Nutrition and drugs, less frequency of fights, more protective matchmaking, improved conditioning methods to name a few.
Everyone is a late bloomer nowadays, you can still be a prospect at 26 if you've never stepped up. I'd say today, the average prime age for a Heavyweight is in his late 20's to early 30's.
It also somewhat depends on styles and whether a fighter can adapt well as he ages, similar to a pitcher in baseball. Sluggers with heavy hands can hang in there quite a while, for obvious reasons. Boxers who make up for loss of speed with experience and heart can hang in there. Swarmers/Brawlers tend to age quickly, unless they can adapt, and most can't. Some can. Pacman did.
It all depends on the fighter, most heavyweights are at peak age between 22-28, then some were defeated at age 24 because they were not at their peak, Ha, Ha, In some lighter weight fighters, between 28-32.
