Results:
Although increasing or decreasing differences were observed in BC and AC blood electrolyte levels of participating subjects, variables were found to be within regular limits, which makes us consider that acute competition-condition exercises do not have any effect on blood electrolyte levels. In order to further describe the correlation between blood electrolyte level and exercise,such studies should be repeated on more subjects, which
will also provide more realistic interpretations.
Yes, exercise leads to sweat, and sweat contains electrolytes. No, you're not, during the average training class, going to significantly alter your electrolyte levels.
Showing me a study that Gatordade (tm) paid for that says you ought to drink electrolye fluids is really not going to be convincing.
Incidentially, do you know how we treat lactic acidosis (which is quite common in septic and trauma patients)? Water. Couple liters of saline to hydrate them and it resolves. Saline, as I'm sure you know, is just about as inert as it is possible for a substance infused into the human body can be.
