EFECT OF INTENSIVE PHYSICAL LOADS ON TESTOSTERONE, CORTISOL AND INSULIN BLOOD CONCENTRATIONS IN ELITE ATHLETES

The aim of the work was to investigate effect intense physical activity on testosterone, cortisol and insulin blood concentration in elite athletes. study conducted with participation 26 athletes endurance events. This assessed resting hormones before exercise acute response after intensive loads. influence loads different direction (strength speed vs incremental load VO2 max achievement) investigated.
 average values total testosterone serum, measured at rest state were 28,2 nmol·l-1, 40 minutes – 19,2 nmol·l-1. mean 506,2 518,1 value morning 6,6 μIU·l-1, loading 5,6 μIU·l-1. It established a significant (p = 0.001) decrease loads; registered changes concentrations not statistically significant. A correlation ≤ 0.05) between maximum oxygen consumption (VO2max, ml·min·kg-1) (r 0.76 concentration, r 0.87 loads), 0.69) 0.51) exercising.
 differences due various achievement). difference depending test found this study.
