In one study, the hydration and electrolyte levels of runners were monitored. Those who got cramps (during athletic activities) did not have hydration or electrolyte levels significantly different from those who did not. Bear in mind that all started the activity with proper levels.
As always with population studies, we may have two very different groups of people getting pooled together. There is the possibility that those who get cramps may just be biologically different in the way they process water and electrolytes. As a crude example: only 40% of hypertensive people are salt-sensitive. The other folks with high blood pressure are pretty much unaffected by the Na in foods (within reasonable limits).
