Somebody sent this to AAT
http://groups.yahoo.com/group/AAT but I
think
this
sort of "discussions" are more suited for s.a.p [some comments between
brackets --MV]

Running Man
Couch potatoes may disagree, but people are fairly well built to run
in the heat.["people"?? A adult young men of a few remote
populations,
they mean?]
Marthons. Millions run in them and shorter races.
The first one who ran the marathon dropped dead... :-D
And the first one in the water probably drowned :-D
Yes, my boy, not unlikely: most aquatic mammals ultimately drown.
But they don't drown with their first long swim...
We sweat more per unit of body surface area than any
other animal, [Yes, never seen in cursorial mammals: it's a waste of
water+sodium: as Montagna said, "a real physiological blunder"]
and our upright posture exposes less body surface to
the sun than would walking on all fours, [yes, that's why all
cursorial
animals walk on all twos...
The upright/shadow "argument"
goes
back
to Lee 1950 (Schmidt-Nielsen "Desert animals"), but it holds only if
you
stand still & completely vertical at 12 o'clock... Nobody hunts
"upright",
of course: it's the best way to alarm your prey...)
and more surface to the
cooling wind. ["cooling" wind in "heat" where air temperatures at
midday
far exceed 37°C??]
When you run, you generate air flow.
:-D
Enough nonsense.
Just because you don't exercise doesn't mean no one else doesn't...
Apparently you are unaware that recent research suggests that endurance
training in athletes can causes cardial arrhythmias and sudden death.
J.Ector cs.2007 "Reduced right ventricular ejection fraction in endurance
athletes presenting with ventricular arrhythmias: a quantitative
angiographic assessment" Eur.Heart J.28:183-189.
Apparently you're unaware they had a sample size of only 47. There's
considerably
more than 47 in these pictures
