Abstract des Autors

The aim of this study is to explore the Atrial Natriuretic Peptide (ANP) response during competitive sports activity in a natural environment. The types of exercise which we studied, were: swimming, football and long distance running. We applied five different experimental protocols: 1. Immersion and 20 min swimming (7 subjects), 2. Swimming 60 min (8 subjects), 3. Long distance swimming in the sea (15 subjects), 4. Football in training match and championship game (8 subjects), 5. Long distance running 60 min (10 subjects). Venous blood was sampled before and after each activity for the determination of plasma ANP and cortisol concentrations. The basal ANP plasma levels of the above examined subjects did not present any differences from those of the sedentary population but we found statistically significant variations in all activities studied. In long distance swimming we observed higher variations (106%) than those found in short distance swimming (28-39%) and immersion (46%). In football the higher ANP increments were found after the championship game (57%) in relation to the training match (27%). The highest ANP increments were observed in long distance running (582%) in comparison to all others under study activities. Plasma cortisol concentration increased in the following activities: swimming 60 min, long distance swimming, football game and running 60 min. The results of this study suggest that the increase of ANP plasma levels seems to be directly related to both the intensity and the duration of exercise. We come to the conclusion that the ANP increase during exercise appears to be influenced by more than one of the stimulating factors which seem to interact in various modes, depending on the physical exercise conditions.
