Fifty Plus (50+) - Go Faster?? - First Freeze Your Butt Off

“Endurance athletes who precool can keep their body temperature below that threshold and perform at their highest level 10 to 20 percent longer than those who don’t precool,” says Stacy Sims, a Stanford University sports physiologist who works with a number of professional athletes and is one of the *nation’s top authorities on thermoregulation.

I still sweat at 20F...While my thumbs freeze.

I guess I should forget the hot chocolate and instead, lollygag on the porch for 15 minutes before I commute, maybe I'll get to work faster!

Same with me only it's my finger tips and the temperature is more like 40F.

The quote you supplied says "10 to 20 percent longer"; nothing about faster.

PERFORM AT HIGHEST LEVEL 10-20% longer. That infers faster if you can perform at peak for longer. In assumption that peak performance means faster.
But, as one that spent many years with ice strapped to his throwing arm........they can have it.

All the icing does is restore the potential you already have. You won't slow down due to heat.

If you could only do a century at mild temps in 5 hours, icing in hot weather is not going to make you be able to do the same ride in 4.5 hours. Icing does not make you any faster than what you've trained for.

OK, so how long does this last? An hour? two? days? Doesn't seem like precooling would help for an event lasting more than a couple hours, but...

I don't precool, I just ice real good on the ride. My butt cheeks were so cold they hurt this morning...another new-found joy of commuting in winter.

What a bunch of crap. You've got to get your core temp up to perform at optimum levels in MOST situations. Why do TT cyclists warm up for 40 min. to get core temp and HR up to optimum levels? Check how many cyclists "pre-cool" at Paris-Roubaix. pfft

And consider swimming. You MUST warm up your core before competition.

Well, if it is based on research at Stanford, it certainly was a very expensive, highly educated bunch of crap.

Pretty much sums it up. Government grant that WE paid for most likely.
