athletes, testosterone, cortisol, insulin, physical activity


The aim of the work was to investigate the effect of intense physical activity on testosterone, cortisol and insulin blood concentration in elite athletes. The study was conducted with the participation of 26 elite athletes of endurance events. This study assessed the resting hormones concentration before exercise and acute response of hormones concentration after intensive physical loads. The influence of intensive physical loads with different direction (strength and speed vs incremental load to VO2 max achievement) was investigated.

The average values of total testosterone in blood serum, measured at rest state before exercise were 28,2 nmol·l-1, 40 minutes after exercise – 19,2 nmol·l-1. The mean concentration of cortisol was 506,2 nmol·l-1, after physical activity – 518,1 nmol·l-1. The average value morning insulin concentration was 6,6 μIU·l-1, after loading 5,6 μIU·l-1. It was established a significant (p = 0.001) decrease of the total testosterone concentration after intensive physical loads; the registered changes in the blood cortisol and insulin concentrations were not statistically significant. A significant correlation was established (p ≤ 0.05) between the maximum oxygen consumption (VO2max, ml·min·kg-1) and testosterone concentration (r = 0.76 resting morning concentration, r = 0.87 after intensive physical loads), cortisol (r = 0.69) and insulin (r = 0.51) after exercising.

It was established the differences in testosterone concentration due intensive physical loads with various direction (strength and speed vs incremental load to VO2 max achievement). The significant difference of cortisol and insulin concentration depending the physical test was not found in this study.
