Hands-free way to prevent athletes dehydrating

According to research, if you're running you can't absorb more than about 28 fl. oz of water per hour through your stomach, and it's a hard thing to carry around a big bottle of water anyway (since you'll be assymetrically loading your arms, apart from anything else). You could put the water into a hydration pack (eg a Camelbak) but you're still limited by the capacity of your stomach to allow fluid into your body. So, why not have a stent put in, and run the water/saline/gatorade/whatever straight into your body? What I'm not sure about is how to make sure the fluid goes in, and that we don't get any air bubbles, but apart from that it should be possible for the athlete to never dehydrate, as long as there's enough fluid in the pack, **but** it removes from them the worry about drinking enough to forestall dehydration.

IV vs. oral rehydration between exercises http://sportsci.org/news/compeat/iv.html
Study participants felt thirstier using IV rehydration than with oral rehydration; maybe there's some psychological effect to actually drinking something. [jutta, Jan 05 2007]


       Thats gross no athlete would ever want that. Just No.

       Yeah, who's ever heard of athletes doing gross things to their bodies in the name of performance.   

       But seriously - the problem seems to be doing IV drips while on the move. Nobody is doing that. If you stick'em with a drip, you want them where you can monitor their vitals. There have been IV drips with saline solution in subjects that exercised (e.g. on a tread mill), but not to study dehyrdration that I could find.

       I read this as some form of athletic Robocop.

       so true..

       There's is always the threat of the drip coming out when running- depending where the drip is inserted (cough)- so there would have to be some kind of secure way of keeping it in... alas for once, sellotape is not the answer to our prayers.

       deoxyribonucleic: the more I think about it, the better it seems to have the stent a bit more permanent - maybe we should insert it in the back somewhere.   

       And jutta: that's a good point I hadn't thought of. At the moment I only run with a GPS and a heart rate monitor attached to me. Perhaps we could get some telemetry attached to that, and use that to pass data back to somewhere else. Then you should get more accurate data from in the field, rather than just someone running on a treadmill

       One could infuse large volumes of saline into handy soft tissues, where it would remain for a time. This puffiness could be resorbed as the marathoner exercised. One might need to cinch up one's drawstrings as the puffy lumps soaked in.   

       I had thought of an idea like this as a way to produce temporary breast augmentation lasting only a few hours (Cinderella breasts).
