Athletes (8 trained medium and long distance runners) have been explored before and after physical exercise under two testing procedures. After the ergometric test significant increases of Ca++ and Mg++ in serum and significant decrease of Mg++ in erythrocytes occurred. A marked increment of the cortisol level and lesser changes of the thyroid hormones have been found. After the specific training program, apart from the significant reduction of the erythrocyte Mg++, a very significant increase of the cortisol level and large increments of T3 occurred. All subjects showed good coping resources, with inter-individual differences for other three psychological variables.
