Abstract

INTRODUCTION: Zinc (Zn) is involved in more tan 70 enzymes of cellular metabolism, like lipids, pro-tein, DNA and carbohydrates metab-olism, protein synthesis. Zn also pre-vents lipids peroxidation and helps in the maintenance of membrane struc-tures. During exercise organic Zn is redistributed in order to face the ex-ercise-induced metabolic stress. In heat conditions body fluids are dis-placed from plasma, a Zn containing matrix, to the skin to decrease body core temperature by mean of sweat-ing. This process can induce Zn loss-es. AIM: The aim the present work was to evaluate the acute effect of heat stress in serum, urine and erythrocyte concentrations of Zn. METHODS: 19 young males per-formed two incremental effort tests in cycloergometer until voluntary exhaustion. Both test were separated with 48 hours of full recovery. The first one was performed in nor-motermic (23ºC) conditions and the second one in hipertermic (43ºC) conditions. Before and after each test 24ml of blood were extracted from the ante-cubital vein. Urine samples were also collected in both moments. Once obtained, samples were pro-cessed to isolate different matrixes and it were frozen until their analysis with ICP-MS. RESULTS: No signif-icant differences were found in se-rum, urine or erythrocyte in both tests. CONCLUSION: This data manifest that acute maximal effort tests do not induce organic modifica-tions of Zn values
