i've seen this in football and heayweight combat sports but i'm sure they exist elsewhere

absolute tubby, fat motherfuckers have world class conditioning, cardio, and strength. meanwhile lean muscular athletes gas out all the time.

Genetics, shit diet, if you got fat in your youth there’s a very good chance you never lose a lot of that fat later

>football
All the FOOTBALL players are lean as fuck, wtf are you on about. Or are you trying to make assumptions based on an American sport? Americans are so fat, their sportsmen are fat, more news at 11.
>heayweight combat sports
Styles, punching power, technique can all bridge the gap for one fight. Case in point - your picrel.

Because they eat a lot of food.
Fat cells aren't nearly as O2 demanding as muscle cells, you can still have good cardio when fat, especially at weight adjusted sports(both people are the same weight)
It fucks you a little when your weight gets so much (250 or so give or take) where aerobic activities like jogging become anaerobic, but again if both people are erhe same weight they have the same issue.

This particular phenomena had absolutely nothing to do with style or technique and very little to do with punching power Ruiz lucked way the fuck out and landed a one in a million shot to the side of Joshua’s head which was turned in a way it never should’ve been and sent his brain rattling around his skull he was cooked after that

He's talking about the rugby adjacent foot, not soccer
It's technically impossible to be perform well at soccer and fat

There are sports where weight is less of a detriment
And some people are just born with an absurd gas tank
