When and why did super heavyweights improve?

The onus isn't on me to do your google searches for you or to crack open a text book. You've got the entire internet at your fingertips. Use it. All im going to say is it's not entire generations of people growing a foot taller than their parents and all of a suddenly being being D1 athletes. I'm not going to waste my time and pay because you didn't pay attention in biology.

 

1. I have a biology degree from a top science program. I also have a doctorate.
2. You just filled a paragraph full of things I never said.
3. You just stepped into a very quiet thread and started acting aggro for reasons that are not clear.

 

Did it start with Bowe and Lewis?

 

Did I mention I'm Santa Claus? Yeah right pal.

 

I completed a portion of the physical for a boxer who is a champion last year. Maybe you should use the search function.

Americans from 100 years ago were several inches shorter on average. A lot of that is due to differences in gene expression. That is called an epigenetic change.

 

A portion of the physical? What does that even mean? I had multiple physicals for the military and they are done by one doctor in about 30 minutes or less. Did you check his balls then realize you had to go home or something? You're definitely not a doctor. Nice try though.

 

Do you think a primary care doctor can examine a retina?

It’s telling how you’re making personal attacks instead of providing a shred of evidence that you know about gene expression.

 

You're claiming to be something you aren't to impress strangers on the internet. You have no idea what is on a physical either clearly and yes.

 

Agreed,, this was a major factor in championship fights

 

Foreman's amateur career wasn't that extensive to win a gold medal was it?

 

Maybe the weakest am record in history to walk away with gold.

 

We have a winner
Next to improving SHWs (which is true to some extend), its simply chance to find some who are top notch and well known.

I´ll repeat my post here:

"According to Ourworlddata: https://d33wubrfki0l68.cloudfront.n...s-interpolation-baten-blum-2012-0-579x500.png
there has been an increase in height since 1940.

Read here https://investing.calsci.com/statistics.html Height (and for our understanding weight) is normal distributed. And keep in mind: The width of the distribution (or probability to find very tall or very short people is extremely dependend on the standard deviation (STD). Your mean doesn´t tell the whole story if you simply do not know further distribution of your data. If you realy want to know how many SHWs existed back then you have to know the deviation sinces small changes are dramatic for the tails of the distribution!

You can add mean + standard deviation here and check what happens: http://onlinestatbook.com/2/calculators/normal_dist.html Check for probabilty for beeing height above (probability for beeing that tall or even taller)

For example, beeing born in 1930 with avarage height 173cm and STD of 3 inch (7,6cm) compared to born in 1960 with the same STD:

Probability to find men with >= 6`4" with mean 173 and STD 3" = 0,0029 -> 0,29% of men are 6`4" or taller

Probability to find men with >= 6`4" with mean 177 and STD 3" = 0,0128 -> 1,28% of men are 6`4" or taller

There is no ratio!!!! If the mean changes like 4cm you will get 4,5 higher probability beeing that tall or taller. But keep in mind if the STD changes your distribution tails change dramatically as well!

Today data: Probability to find men with >= 6`4" with mean 180cm and STD 3" = 0.0331 -> 3,31% of men are 6`4" or taller --> 11,4 times more SHWs than born in 1930. There is no ratio!!!

Now multiplicate the probability with the amount of people in the US: 1950 = 150M, 1980 = 225M, 2015 = 320M Lets say 1/6 of the population are men in the age for boxing.

In 1950 for 20 year old boxers: 72.500 men 6´4" or taller
In 1980 for 20 year old boxers: 480.000 men 6´4" or taller. (6,6 times more than 1950)
In 2015 for 20 year old boxers: 1.765.333 men 6´4" or taller. (24,3 times more than 1950)

@NoNeck Forget about this fellow, he´s not even able to understand that a body mass index for athletes with the same bodyfat% becomes geometrical ratio...

 

The population also includes most of the world now, not just Western Europe and the Americas.

 

True. As well as thousands of poor black boys who simply had no chance to show their talent prior the 70/80s in the US.

 

What has this to do with my post you quoted ?
Not sure if you are agreeing or disagreeing.
