Mineral metabolism and oxidative stress in Brazilian military under undergoing strenuous exercise

After strenuous exercise performed by the Brazilian military, there was a moderate increase in oxidative stress confirmed by the increment in TBARS, so the health risk should have been minimal. The basic blood count showed values considered healthy indicating a rigorous homeostatic control of the hematological parameters for this type of exercise. The remaining parameters suffered significant alterations: decrease in sodium, increase in potassium, decrease in chlorine, decrease in magnesium and increase in copper. So there was a good metabolic adaptation to the conditions of physical overload, without representing a risk of mineral misbalance.
