Summary
The levels of certain hormones and metabolites were investigated in 8 female physical education students, who were not taking part in any special training program, 6 female racing cyclists and 6 female septathalon athletes. The investigations with the students were carried out at two different points of time in the menstrual cycle, during the early follicular phase and in the liate luteal phase. The investigations with the high-performance athletes were independent of the menstrual cycle.
Stimulation of TRH leads to increased secretion of prolactin and STH which makes it possible to identify borderline basal levels of prolactin and thus improve the diagnosis.
The basal levels of the hormones prolactin, Cortisol, STH and the catecholamines were determined along with the metabolic indicators FFA, free glycerol and total serum protein. Following TRH stimulation the blood parameters were measured after 10, 20, 40, 60 and 150 minutes. The test persons were then subjected to step-wise increasing bicycle ergometric exercise whereby the heart rate, lactate and glucose levels were measured to exhaustion.
Directly following this exercise all the blood parameters were measured again and a second TRH stimulation was carried out with measurements of the above-mentioned parameters after 10, 20, 40 and 60 minutes.
