no it's the opposite

eh, I'm willing to believe either.

So what is it guys? Show me your sources and prove to me which one of you are correct.

True for the most part.
Distance Runners --> Majority slow-twitch
Sprinters --> Majority fast-twitch

but the comes the chicken or the egg question

does the sport MAKE one's muscle fiber composition that way?

or does one automatically get drawn to the sport he or she has the composition for (this is true in the very hi end levels, but what of high school sports?)

You try sprinting,and I mean seriously trying it.That is some shit right there,can honestly replace squatting once you get your quads looking how you want to

Very good query. I myself don't have an answer for it.

i would like to say that there exists a relative amount of muscle 'plasticity' that each person possesses, regardless of how one's fibers are divided, PLUS there has been shown to be muscle fiber type 'switching' (if you will) in certain models.

but i imagine most anyone can make a ton of gains in sprinting by practice/technique, getting a shitton stronger (squats), and increased neuromuscular control.

to get better at distance is a very different beast.
just run a ton, and lose weight, preferably muscle, as its metabolically expensive, hence the relatively high BF% all distance runners (minus the VERY top) have, especially to sprinters. and why joggers have as high a likely hood of CVD as the general population (altho joggers do not get metabolic syndrome)

it's a combination of both genetics and environment. Some are genetically predisposed towards slow twitch fibers and as such will make better long distance runners. However, if that same person trained for sprints instead of distance, say, from the time he was born, he'd have a diff composition.

also, don't forget about pink muscle (which would be slow + fast twitch/ dark + light meat)

you have to be THIS tall (points over your head) before you can participate in this discussion.

in dialogues about muscle plasticity and hybrid fiber conversions, i doubt we need your 7th grade commentary on 'pink' mussels, that is, unless you have (tartar) sauce.

Would be favorably genetics to sprint powerfully and distance run well assuming one had mostly pink tissue?

No, actually it's in the genetics, but when you train for a specific sport the muscles which hypertrophy are the ones you are using most. So that explains the slow-twitch endurance on distance runners and fast-twitch muscle power on sprinters.
