Old myths die hard.
It used to be thought that low potassium was the major reason for cramping - hence the emphasis on eating bananas that are rich in potassium.
But that is no longer believed.
[Still eating a banana after a match or practice is not a bad idea. It is fairly easy to digest and contains enough carbohydrates to start replacing muscle glycogen (muscle's immediate energy supply) lost during play.
During a match, some can tolerate eating a banana - others develop intestinal cramping.]
