Re: Core cooling and Work Output experiment

Bad idea to use frozen anything. Any time your skin gets too cold, it vacoconstricts. That means that all that blood that used to go to the surface of your hands is no longer going there. It is meant to prevent heat loss because your skin thinks it's too cold outside, and it has to keep your internal body warm.

Any object below 60 degrees on the surface of your skin is too cold, and will begin to induce vacoconstriction.

How about just a cold dunk?

Re: Core cooling and Work Output experiment

Put the ice packs on the sides of your neck, under your arm pits, and the tops of your thighs where they meet in the middle (watch out for the junk). Large superficial arteries in those locations, and even if you get any vasoconstricion from the cold, this is going to significantly cool the blood/body.

Re: Core cooling and Work Output experiment

Doesn't this contradict the "be ready for anything life throws at you" spirit of crossfit?

Not as I see it. The higher training volume just means you'll be more ready for what life throws at you, whether you have a $2,000 cooling device handy when that time comes or not.

Re: Core cooling and Work Output experiment

brandon

i was thinking the same lines

kiddie pool$25

couple bags of ice$5

water $0

jump in, and i'd bet its faster drop in core temp than hand device. and cheaper too, you just have to exercise wet.

ive been to spas where they have cold pools, i'd like to find one around here.

at hospital i've seen people packed in ice to drop core temp, given the above , the immersion process sounds promising

Re: Core cooling and Work Output experiment

Yeah, well, I don't know how useful it would be for regular training, but since we're just sort of experimenting right now, it'd be as good as anything.

Training volume wouldn't necessarily increase, though training efficiency may. Steroids are a lot more effective for increasing volume.

But my main contention is, what about being able to perform in hot/humid conditions without this crouch?

That said, I can certainly see your point about being able to push beyond one's normal boundaries.

Re: Core cooling and Work Output experiment

I think that's exactly the idea, Tim--it's a non-steroidal way to increase volume by decreasing recovery time. Coupled with the thread on how humans are supposedly well-designed for long-distance running primarily because we more effectively cool ourselves over the long haul, maybe there's something to it.

Re: Core cooling and Work Output experiment

If you want to do whatever you can to keep cool, and keep it on the cheap, just buy a Coolvest (www.coolvest.com (w/f safe)) - it's made to prevent vacoconstriction.
