"It's pretty clear that the higher your VO2max, the more quickly your glands respond to the signal to start sweating."
is it?
this study is a little more updated
A 2011 study published in the American Journal of Physiology found that sweat rate depends on your physical work and your body’s surface area rather than on VO2 max. In other words, you’ll sweat the same amount running a seven-minute mile whether you’re in tip top shape or not, assuming you haven’t gained or lost any weight. This study concludes that sweat is an indicator of the physical work you’re doing, not how fit you are. (Read more about this study at Sweat Science.)

which in my experience means that an untrained person in anything will tend to reach their max work load rate faster then someone who is trained.
having run cross country my self as a youngre man, if my memory severs me people who never run before broke a sweat before those who had.
in other words, running for example 2 miles out of 12 was nothing for those used to it, for those not they reached their max work load rate faster.
makes sense to me, and also what I've experienced,,,,could be wrong...
