Ridecamp: Re: [RC] Potassium in electrolyes

Interesting...are they suggesting that it the accepted elyte formulas create
a situation where there is an excess of potassium?  I can see where it would
decrease acid production in the stomach (it is required for acid secretion
to occur), but by the same token it seems to me to be a metabolic alkalosis
waiting to happen.  Not to mention which, I would think that if you leave
the potassium out, but continue to give sodium that would interfere with the
proper functioning of the sodium/potassium pumps that are so important in
the cells.  I'm also not convinced that it will reduce the incidence of
abnormal heart rhythms, since a deficiency of potassium can also cause
cardiac arrhythmias.

I'd be interested in reading that article--is it available online anywhere?
