Anybody know the history of the body types?

[Infinite`Eternal`Forever]

There's 3 body types:

Ectomorph, endormorph, and mesmomorph (sp?)

The first are the skinny types of people. They have a hard time gaining muscle and burn calories easily.

The second are the fatasses. They gain weight easily.

The last gain muscle easily and usually look built without having acquired any muscle mass at all.

My question is, how did those body types become the way they are? What conditions did our ancestors have to live under in order to possess the body types that operate they do?

I'd say its more to do with geographic location than anything...

People in climates with long winters would gain an evolutionary advantage to storing fat quickly... for both insulation and future energy...

I imagine that all three body types could be linked to similar types of climactic influences.

You don't have to believe in that schema for body types, at all.

Why do you say that?

In a nutshell it's the ratio of fast twitch to slow twitch muscle fibers comprised in the over all muscle tissue.

Here's a good read... http://en.wikipedia.org/wiki/Muscle

Aerobic events, which rely primarily on the aerobic (with oxygen) system, use a higher percentage of Type I (or slow-twitch) muscle fibers, consume a mixture of fat, protein and carbohydrates for energy, consume large amounts of oxygen and produce little lactic acid. Anaerobic exercise involves short bursts of higher intensity contractions at a much greater percentage of their maximum contraction strength. Examples of anaerobic exercise include sprinting and weight lifting (http://en.wikipedia.org/wiki/Weight_training). The anaerobic energy delivery system uses predominantly Type II or fast-twitch muscle fibers, relies mainly on ATP or glucose for fuel, consumes relatively little oxygen, protein and fat, produces large amounts of lactic acid and can not be sustained for as long a period as aerobic exercise.

Hmm. Well then would you suppose that the ninjas of feduel Japan became ectomorphs? Sounds a little out there at first glance..but could be plausible.

naw, not for that reason at least...

I'm talking from an evolutionary standpoint... it would take many generations for a climate to work its course through natural selection...

[WhispersInTheDark]

Some 'science' tends to oversimplify phenomena into 'averages' that are not a true reflection of diversity or 'types' at all. So it is in the case of Sheldon's somatotypes, in my view... trying to type personality fit with body type is an even less valid part of the model, and that is what it was designed to do. Crap.

Anyway, using this categorization you will find one accuracy... that 70%+ of all Americans are now bloated endomorphs.

Ok. I see what you're saying now.

[pack3tg0st]

ya know, now that I think about it... the reverse could be true as well IEF...

Suppose you come from an evolutionary branch that developed where food was short and in constant demand... then a 'stick skinny' genetic code would do you well... but then suppose ove rthe years your genetics to sustain yourself off of minute amounts of food is no longer necessary...

now suddenly you've got a situation where your body is 'trained' genetically to store as much food away as possible for sustainablilty through famine... but its not needed... thus, you just keep gaining weight...

I dunno, I guess either could be possible... I'm not an evolutionarly biologist.. (but I play one on TV)

:D

I'd be willing to bet that you're right on this one. But let's get back to the ninja thing for a bit:

Are you sure we can't rule out the possiblity of their fedual environment playing a role in determining their tradtionally small frame? I mean they've always been protrayed as very fast, agile, and quick warriors. Which would serve them well for their battles with the samurai. But then again, it's been disputed if they ever even existed at all. So who really knows.

The same situation could be said for cavemen. They had to lift a lot of heavy ass shit like boulders and shit. They also had to deal with the dinosaurs. So that environment could have been a reason why they were (or portrayed as) very muscular. Which would make them mesmomorphes.

lol you're timeline is goofed up methinks...

Cave men were way before 'ninja's'.

I'd wager that feudal japan falls significantly short of the the thousands of years necessary for natural selection to work its course.

Now, its possible that it is diet related... i.e. the japanese have historically had a diet based off seafood, veggies, and rice... Maybe their stature is in response to the body having such food for thousands of years...

I don't know, when we start speaking of body frames and the likes, I would think you have to take into account the traits also inherent in the three branches of humanity (Caucasiod, Negroid and Mongoloid).

if we could see statistics that break each of the branches of mankind into the three body types you mention... then we'd be getting somewhere...

But then agian... we're all Mutts these days, so it may actually be quite difficult...

Sounds like a Human Genome question to me.

I knew this man, lol..I just added that in there for something else to think about.

Not necessarily. Humans aren't giraffes. Cultural influences began to affect natural selection as soon as people began to form tribes, the dates of which get earlier and earlier.

I'm a bit woozy atm so I may not have phrased that correctly and reserve the right ot put it more coherently tomorrow.

That's if you can actually find the thread again....
