ABSTRACT In sports medicine, very little attention has been given to magnesium compared with potassium and calcium. Magnesium ions (Mg2+) play a central role of neuronal activity, cardiac excitability, neuromuscular transmission, muscular contraction, vasomotor tone, and blood pressure significantly related to physical performance. Exercise is a potent stressor that appears to lead to magnesium depletion through alterations on blood magnesium levels as well as increased sweat and urine excretion. After exhausted swimming (3-4 hrs) in rats, the iCa2+/iMg2+ were significantly decreased. The Na+, iCa2+, iMg2+, and anion gap were significantly increased. These data suggest that exercise could alter blood iMg2+, iCa2+ and the ratio of iCa2+/iMg2+ and point to important uses for iMg2+ and the ratio of iCa2+/iMg2+ during the training and examination of athletic performance in sports medicine.
