Document Summary

The recommendation is to consume any needed fluids several hours before the event to make sure there is already absorption taking place and that the fluid is(cid:374)"t just s(cid:449)ishi(cid:374)g i(cid:374) the athlete"s stomach. It also gives the athlete e(cid:374)ough ti(cid:373)e to pee out (cid:449)hat they do(cid:374)"t (cid:374)eed. Co(cid:374)su(cid:373)i(cid:374)g (cid:271)e(cid:448)erages with a little sodium or a small salted snack before the event can help stimulate thirst and retain the needed fluids. About 5 -7 ml per kg body weight is the recommendation.

That means the however fast the water and nutrients empty into the small intestine from the stomach will be a limiting factor of absorption. Any rehydration fluids that we choose, for example water or gatorade should have a quick gastric emptying rate to optimize hydration.
