Stanford's Cooling Glove Stanford University

Almost all mammals have a network of veins near a hairless part of their skin that controls rapid temperature management--and it's no different for people. For us it's the palms (as opposed to, say, a dog's dangling tongue). But like some other biological processes, the technique can be gamed, with engineering topping physiology. That's the case with a body-cooling glove out of Stanford that researchers say might be more potent--and obviously much more legal--than steroids.

These hairless patches are the dominant places for heat transfer with the environment; take a thermal scan of a bear (carefully) and you can see the nose and feet light up. The networks of veins beneath the skin, called AVAs (arteriovenous anastomoses), let only negligible blood flow during cold weather (to keep a person insulated) but can account for as much as 60 percent of cardiac output during warm weather or exercise.

The glove plays off this reaction. We have other AVAs, but the palms are the most prominent, so that, of course, is where the glove does its work. The setup sounds simple: it doesn't look like much more than a plastic glove hooked up to a portable cooler. But when a hand goes into the glove it creates a slight vacuum, which causes the veins in the palm to expand and draw blood through the AVAs. A lining of chilly water in the glove cools off the blood as it starts to circulate throughout the body.

The researchers claim that the cooling helps in recovering from exercise or competition so much that it could be more helpful to an athlete than steroids, and some teams--including the San Francisco 49ers, Oakland Raiders, and Manchester United--are using a version of the glove in the hopes that it really does.

I have to call B.S. on this. Not saying this dosn't have some effect but the only thing better than steroids are better steroids plan and simple and if you don't agree you obviously haven't done them.

I have heard taking a cold shower after a strong work out, allows for the person to go back and repeat the same work out for over all better strength gains.

For the above article, I wonder how they eliminated the placebo effect?

I guess the above article is suggesting we put our hand in a bucket of ice water after a good work out in preparation for another work out. Seems easy enought to do. I will give it a try.;)

This is some real old news. I mean it was at least a year ago when they showed a prototype of this kind of thing on Discovery Channel(I don't remember what show). There they didn't use vacuum just some plate with specific temperature to cool down your heart and other intestents. It showed real improvements on athlets.
The point is, I don't see the news here. It's like saying that Curiosity went to the Mars using a rocketship and that rocketship is newer seen before new invention.

Sorry for my bad english, it's not my first language.

chasepcc,

Your own suggested self use of steroids not withstanding, we would all love to see your peer-reviewed data on why the work of those at Stanford is "B.S."

I would also like to know your metric for "better". Are you suggesting that the the body-cooling glove perhaps won't cause as much Gynocomastia as steroids do?

wow, talk about old news, I saw this on the science channel like 2 years ago, they had the host put an internal thermometer down his throat so they could get an accurate core temp, then they had him run until exhaustion, they then kicked in the glove, lowered his core back to normal temps and he just kept running, to his amazement he could just keep going.

@chasepcc,

Follow the link at the bottom for a more in depth article. One guys went from doing 180 pull ups in a workout session to over 600 in a matter of weeks. That is incredible and that is the exact kind of thing a person such as myself is looking for. I could go out and run a hard sub 12 minute 2 mile, cool myself off with the glove and then go out and do it again! Talk about rapid performance gains!

I hope it hits the market ASAP, I will definately be getting one. Hopefully before my upcoming deployment to Afghanistan because if I do get one and bring it with me myself and the rest of my squad will use it after every combat mission.

I'm going to wait for the genetic manipulations and enhancements that are coming within the next century.

i'm still gonna call bs and gyno really! not even addressing that one. like i said i didn't say the glove didn't have an affect but no way i will believe sticking my hand in ice water (or ice water vacuum) is better than the juice. Bigger stronger faster...start there

@chasepcc,

It is not sticking your hand in ice water. Read the article posted by Standford on how it works. This thing acts like a heat exchanger for the human body and allows a user to have incredible muscular endurance. One really tough set in the weight room is one thing, being able to do 4 really tough sets in succession is another entirely. The pull up example test Standford did speaks for its self. I really hope it works as well as it claimed.

ok now hooah who said i didn't understand what a heat exchange was? or even the affects this would have on the body i get it lol they only thing beating some good gear here is cookiee's comment but that's far away and the powers that be will thrown the ban hammer at this as they have band steroids hyperbolic chambers and blood doping as well as everything else that works. if your worried about something working as well as they are claiming a good cycle of gear is tried and true. isn't it against the rules to hyperventilate at the Olympics now... anyways another good place to start on info is the history channels science of steroids.

@ chasepcc
The effect has been shown in multiple trials. And yes the pacibo effect has been tested as well. This cooling technique has benefitted many of our deployed soldiers.

The best way to understand and apreciate the effect is to try it! If you know what you're capable of in the gym, then put it to the test, you should see a significant increase in work the very first time!
There's more going on than just a cooling of the core and the muscles. While ice water and cold showers may feel good, they do not produce the same benefits.

This technology, vacuum and all, was first tested 5 years ago. Do a web search for "military cooling glove" and you will find several articles on it from May 2007. Would have been nice to know if there is anything new about this or if it really is 5 year old technology.

lol holly crap get it threw you head i understand what it does and the benefits. still does not will not no way no how trump good gear. plus old news as several other ppl have stated the title of the article is all that's messed up the genetic mods are the only thing that's going to beat steroids period damn and as i stated before this will be banned. i mean i'ed hate for someone to have an unfair advantage over someone else who didn't use an ice water vacuum glove or didn't have the right genetics either way.

Guys, the benefits this offers and the benefits of steroids are completely different. Steroids are for quick muscle mass and toning, this is used for recovery after/between workouts. And this IS the same concept as a cold shower after a workout, as anyone who has taken a cold shower after a workout will tell you: your body feels great, like you're superman or something.

why not just look at statistics from athletes in cold climates ?

Ardent Ward,

You should do some research before you post an argument.

Steroids are not designed to build quick muscle and "tone" as you call it. In fact, the "tone" I think you refer to has only to do with diet and body fat percentage. Steroids on the other hand ARE used for recovery. In the case of Human Growth Hormone (HGH), anabolic steroids are used to help the muscles recover and repair more quickly. In turn, this allows an athlete to train harder, and for longer periods of time with none of the negative signs of overwork.

In fact, Stanford's temperature regulation glove and traditional anabolic steroids are very similar in what they accomplish, they just take different paths to the same goal. What is amazing about this technology, though, is that it accomplishes the same end goal without any of the negative side effects associated with long term steroid use (i.e. Gynecomastia, shrinking of the testicles, and premature balding).

In addition, this is different from ice baths and cold showers in that the pressure difference actually keeps the blood vessels open, allowing the body temperature to change much more rapidly.

So we cool the muscles, so that they are not as stretched and prone to damage. Ok. But the innards is key here too. When cooling the muscles, we are affecting both oxygen consumption and acidosis as well. We are also slowing the proteins and putting our monthly cycle of natural cell replacement by mitosis into a different biorhythm. Without any of these base questions having answers, this has no business being tested on any animal, let alone a human.
