Q. I cramp easily even when I have not done anything strenuous, but more so after playing tennis. Drinking Gatorade before and after tennis helps some. What am I lacking?
A. If Gatorade helps somewhat, you may be low in some electrolytes. We have heard from another tennis player that drinking Pedialyte after a match can help prevent cramps. This liquid formulation is designed to help replenish lost fluids and minerals for babies who may become dehydrated from diarrhea or vomiting.
