[Seasonal variations in hematochemical and urine parameters in a group of professional cyclists]. / Analisi delle variazioni stagionali dei parametri ematochimici ed urinari in un gruppo di ciclisti professionisti (c.p.).

Purpose of this study was to evaluate the modification of some biohumoral parameters in a group of road-race cyclists during a sporting season. The following conclusions can be drawn: at the beginning of physical exercise, an inverse relationship between serum iron and haemoglobin content can be found. This can be probably attributed to the physiological response to fatigue. Hepatic and renal functions were normal during continuous and severe physical stress like Giro d'Italia. This can be due either to correct alimentary and hydric intake and to an appropriate pharmacological therapy.
