Could it not just he that now there are more big men therefore more big boxers therefore more big elite boxers? The average height has increased by 3 inches in the last 90 years. That is directly in line with the evolution stats you posted. The idea that giants of yesteryear would be as good as the elite giants of today is folly.
Let's quit talking about evolution as a rational explanation for the height increase because it's not. Evolution occurs over hundreds of thousands of years. Not 100. Another thing, evolution is not needless change. It is adaptation. Growing taller for the sake of growing taller is not evolution. There is nothing that necessitates that humans grow bigger, if anything the being smaller is far more advantageous than being bigger. From a survival perspective at least. Also, evolution has problems with it just like all other scientific theories it just happens to be one of the more plausible theories so let's not throw it around as if it is scientific law.
Whether it's evolution or not, man is over 2 inches taller in average than they were 100 years ago. Not just in boxing, in the world. Call that phenomenon whatever you want, but it is totally sensible that boxing has been subjected to the same phenomenon since the height as increased at the same rate. The taller the man, the shorter the fight, the larger the weigh in window, the heavier the man.
The heavyweight division in boxing is nothing to do with the average population this is an extreme category.Extreme power and size. Is Mike Tyson an average Joe because he has similar height ? I doubt it.
yes that could be a good enough reason if this is what happened when America produced the worlds biggest people.
yes but if the heavyweights are 3" taller in 90years what do you make of the weight increase? Does the three extra inches correspond with the increase in weight that arrived with that 3 inches? The weight has went up by how much? And does "evolution" explain why men of the same height as years ago weigh more? I think we need to look beyond evolution for the answer.
Fights went from 15 to 12 rounds. That's a 20% change. Fighters have 24 hours to rehydrate now. More than that if a guy can last 12 rounds weighing 17 stone he's no reason to trim weight.
Heavyweights on average haven't grown that much taller in the last 30-40 years. You can almost guarantee that they are about two inches shorter than listed. They do it for the same reason that high school/college athletes list themselves a few inches taller than they really are. Recruiting/management purposes.
