What is the role of Ca and K as related to post exercise cramps?

Welcome to Just Answer:

A shift in the muscle cellular compartment levels of potassium and/or calcium can cause significant muscle cramps. Increase exercise can cause dehydration, with imbalance in the muscle cells concentration of potassium and calcium, and hence muscle cramps. On the other hand, there could be loss of potassium with exercise causing which can also cause muscle cramps. The solution is optimal level of potassium. I suggest that you maintain adequate potassium supplement through eating banana regularly, and/or good multivitamin supplement with potassium and calcium. Post exercise cramps is more of a problem with potassium than calcium, and can be significantly resolved with good electrolyte fluid hydration such as Gatorade, and regular intake of banana or potassium supplement if you frequently engage in high intensity exercise.
