Abstract des Autors

It is a well known fact that endurance training increases the blood volume, which is due to a higher increase of plasma volume (PV) than of the erythrocyte mass. Whereas an increase of PV can already be observed at the beginning of a training period, a marked elevation of red cell mass can be detected not before 3-4 weeks of a regular training programme. A single bout of exercise leads to increased reticulocyte counts in the peripheral blood, which is attributed to a predicted increased erythropoietin activity. But the first measurements of erythropoietin concentrations in the blood serum during and up to 5 hours after maximal and submaximal bicycle exercise by using a specific radioimmunoassay demonstrate no rapid exercise influences on this parameter. Thus, we may state that the erythropoietin system is not responsible for the reticulocytosis occurring immediately and up to two days after exercise. Other factors as the human growth hormon and testosterone must be considered for this effect. Verf.-Referat
