| Popis: | Age is a meaningful factor modulating the functioning of the human endocrine system. In our research, the factor stimulating the pituitary–gonadal axis was a 400 m race. In this type of effort, glycolytic and lactic acid transformations are dominant and a fundamental increase in lactic acid concentration is noted. The aim of the research was to compare the response of the pituitary–gonadal axis in physically active men of various ages after a 400 m race. Nine men aged 21.7 ± 0.7 years and nine men aged 60.0 ± 3.4 years took part in the study. Blood samples were taken from the elbow vein before the race at 08.00 and immediately after the effort. The levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), total testosterone and free testosterone were determined in blood sera. The concentration of lactic acid was measured in full blood at 5 min after the race. Before the effort, statistically significant differences in the concentration of FSH and free testosterone between the two age groups ... |
