I speculated that they began the season with a huge advantage over their opponents in heat adaptation, which became decreasingly relevant as the autumn progressed.
In 1978 I attended a dinner sponsored by Tau Beta Pi (an engineering society) at which Dr. Cade was the featured speaker. In his words, the player told him that his drink "tastes like ****!" Dr. Cade continued, "Having never tasted ****, myself, I could not vouch for his claim. Nevertheless, we did work to improve its flavor."
As to the original issue, I recommend drinking water and snacking on any food high in potassium.
Orange juice is high in potassium. But, I think it's a good idea to keep your electrolites in balance. I don't think it's helpful to supplement with only one.
