And for this subject we go back to Biochem 480 with Dr. McRae and your friendly neighborhood EWU Chemistry faculty. Sodium, Potassium, Calcium and Water. Calcium is the minor player, generally we have plenty in our system and not likely to be the culprit. The other three are the major players, however, as our doctors all like to remind us, we all get more than our fair share of sodium from the salt rich american diet. So not a likely culprit. Water is a huge issue, athletes almost always need more of it but may not know how and when to do it. Talk to your marathon runners and your triathletes, they almost always have a measured intake to make sure that they are hydrated well in the days leading to competition as well as how much and when to take more in during competition. Team sport athletes often don't have this well mapped out as some of us have already mentioned. Potassium, is the under the radar element, just as important a sodium but not nearly as prevalent in our diet. Easily remedied at breakfast time the morning of the game. Those are my picks for likely culprits, pregame hydration and potassium intake.
And since jobs are scarce, that is the most ive made use of my Chem Degree since I graduated, outside of helping my sister with her chemistry and math homework now that she is at EWU.
