Zusammenfassung
Bei 131 Untersuchungen unter standardisierten Laufband- resp. Fahrradergometerbelastungen sowie im Leichtathletiktraining resp. beim Marathonlauf wurden Prolaktin- und FSH-Bestimmungen durchgeführt. Drei verschiedene Trainingszustände bei Frauen (Untrainierte, Hobby- und Hochleistungssportlerinnen) wurden untereinander sowie mit dem Fitnesszustand von Hobbyläufern verglichen. Prolaktin stieg mit zunehmender aerober Kapazität und damit zunehmender Belastungsdauer im Labor signifikant an. Die Prolaktinmaxima nach einer disziplintypischen Trainingseinheit wie nach dem Marathonlauf waren höher als unter Laborbedingungen, doch ebenfalls erst 5–10 min nach Belastungsende. Männer wiesen signifikant niedrigere Prolaktinantworten auf als Frauen. Zwischen der Höhe der Prolaktinantwort auf die körperliche Belastung bestehen signifikante Beziehungen zur Zyklusinstabilität. Damit läßt sich ein großer Teil der sportassoziierten Zyklusstörungen erklären und gegebenenfalls gezielt therapieren.
Summary
In 131 investigations prolactin and FSH were measured during standardized treadmill or bicycle ergometer exercise as well as during track and field training or a marathon run. The different physical fitness states in women (untrained, hobby and top athletes) were compared to each other as well as to male hobby runners. In the laboratory exercise tests, prolactin increased with higher aerobic capacity and, hence, with longer exercise time. The maxima of prolactin were significantly higher after discipline-specific training and after the marathon run than under laboratory conditions, but the maxima occurred at the same time: 5 to 10 min after the end of exercise. Men had a significantly lower prolactin response to physical effort. Significant correlations were found between the irregularity of the menstrual cycle and the level of the prolactin response to exercise, in absolute values as well as in the area under the hormonal curves. With these findings some of the sport-associated menstrual dysfunctions could be clarified and successfully treated.
