CATECHOLAMINE EXCRETION IN INDIVIDUALS ENGAGED IN EXTREME SPORTS

The specific features of the excretion of catecholamines in parachutists at various stages of preparation for and after performing the jump have been studied. It was revealed that the beginners engaged in parachuting, i.e. parachutists inexperienced in jumps react with a significant release of epinephrine and cortisol before boarding during the jump. At the same time, the excretion of norepinephrine in these athletes under the same conditions does not change significantly in comparison with the initial data. Mass class parachutists, i.e. athletes having a certain experience in jumping during preparation for and in the process of the jump react with a significant release of epinephrine, cortisol and norepinephrine. At the same time, these athletes had significantly higher level of excreted norepinephrine than adrenaline and cortisol. Highly skilled parachutists (masters of sports and masters of sports of the international class) react with a significant release of only norepinephrine during the preparation for and performance of the jump. Consequently, the excretion of catecholamines in sportsmen regularly engaged in parachuting depends on the level of athletes' qualification. The higher the level of training of parachutists is, the less changes occur in the values of excretion of catecholamines.
