Again, I feel like we're having two separate debates on this thread. Some, like the poster quoted above, are discussing the potential of untrained young adults to run sub-60 in the 400. Some, like myself, are debating the potential of properly trained young adults to run sub-60.
In the case of "rokurunner"'s 250 students in the 12-14 age range, we're almost certainly talking about a group of students who are not properly trained for the 400m. Not to mention the fact that we're talking about 12-14 year olds who have barely begun to experience puberty and adult-like muscle development.
Most post-high school males don't ever do any kind of prolonged sprint-specific training. They have no reason to. They aren't in competitive sports anymore. So of course they can't break 60. I referenced my high school track team because I believe it's a more realistic sampling of what can happen when you take a group of average young males and actually have them participate in a full season of sprint training. Again, my track team was not very good. We didn't have try outs, and our 4x400 team was never even top 3 in our own conference, to my recollection. And even on our very mediocre track team, running a 57-59 second quarter wasn't good enough to be on the 4x400 team. We had about half a dozen guys with 57-59 second speed who were considered emergency alternates, or perhaps participants on the rare "B" squad at dual meets or something.
Ummm...pretty sure that folks who go out for a track team do not exactly represent an unbiased sampling for purposes of running ability.
