What happens to a fighters speed and power as he moves up weight classes?

Does it go down?

How significantly does it go down?


Can you name some examples of fighters that were very fast or powerful and then went up weight divisions, lots of them?

I think it depends on why they move up. If they move up bc they’re killing themselves to make weight, then I would expect their power and speed to still be there or be a little better. It they move up while still being able to make the previous weight just fine, then their power probably won’t be as impressive. For example lomachenko at 135.

Thomas Hearns went from welterweight all the way to cruiserweight and carried his power with him. Still looked fast in every weight class.


Roy Jones jr retained his speed and power though all of his weight classes.


Robero Duran seemed to lose some power past 147. He appeared to still have the quickness though.


I think it depends on the fighter.

If he takes HGH and steroids he keeps the power

The more weight you put on your frame means the harder your internals gotta work to keep you moving.

This is why people have a natural weight class that the scale doesn't dictate, your bone structure and natural muscletone does. Very few on this forum get that, in fact most modern trainers don't even understand this, because they decided one day someone with a kinesiology degree and no prior experience with boxing somehow knows how to get a fighter in shape better than 200 years of on the job practice.

If you are smaller with more weight on you and are going up against a bigger guy with less weight on his frame, all the disadvantages are in your court (unless you are just a more skilled / confident fighter) but all things considered the same.

So when you. Move up, your shot. Doesn't hurt a bigger guy as.

You probably. Marginally gain a bit of power and punch resistance going up, but it doesn't scale. Proportionately, and with it comes fatigue and a loss of agility.

I feel. Some. Fighters actually hit harder at lighter weights. They were. More limber and had more velocity on their shots. Duran campaigning at 135 would have probably torn a lot of 147 lb fighters up even if he came in light.

I knew a man who could take off four or five inches for a fight. A tall man coming in short like that is a dangerous thing!

Do you mean raw speed and power, or speed and power relative to the weight class they are in?

I'd rather add 4 or 5 inches, if you know what I mean.

Fact!



From my own experience. I can only speak for myself.

3 pounds more and there's a touch less speed with a touch more power. I'm fighting

In between was the happy medium.

3 pounds less and the speed was uncontrollable with less power.
I was able to tag you and throw combinations or just throw flurries. Better for the point system. I'm boxing
