Need Answers about potassium

[JessicaP]

During exercise potassium accumulates in the fluid around themuscles. How does the body counteract this condition?

I have searched all over for a direct answer to this question but all the sites I went to were trying to sell supplements and I could not find anything to get the answer to this.

i don't see why K would accumulate around muscles during physical exercise. But the answer is probably the Na/K pump.
