Title: cold water and exercise
Post by: Ema on 06/11/2006 01:54:01

This is my very first topic in this forum.


So, it is recommended to have cold water after exercise, why?

I think it is just to aid in dropping the heat.

But our instructor said : it aids in stomach absorption ??? when I asked how , he said there are studies that showed certain minerals and vitamins are faster absorbed with cold water . I searched PubMed ..I didn't find such info.

Anyone knows ? why better to have cold water during exercise? do u know anything about absorption being correlated to temperature of drinking water?

Thanks.

Hi Ema

this sounds like rubbish to me. Once water enters the body it doesn't stay cold for long. The liquid runs down the oesophagus, behind the heart, picking up heat all the while. By the time it reaches the stomach it's close to body temperature, 37 degrees celsius.

All of the body's components are optimised to work at this temperature, including the processes that absorb nutrients and minerals.

I'd suggest to your gym instructor that he sticks to advising people about exercise and fitness and leaves gatroenterology to the people who know what they're talking about!

Thanks Chris.

I wasnt convinced at all with what my instructor said and this was the primary reason for me investigating abt the subject matter. I tried to explain it as possibly activation of thermo receptors in the GI tract might elicit some vagal stimulation or increase motility .. but this sounds as trying to make sense of  nonesense

you made a point, the optimun temp for almost all functions in our bodies is 37 degrees celius.
