The dynamics of adaptive hormones in the qualifying round of games in basketball

Abstract

The article focuses on the dynamics of catecholamines and glucocorticoids under competitive stress during the qualifying round to the big league in basketball. The participants in the experiment were 5 players of the same women team, among them are candidates for the master and the masters of sport, at the age of 19 to 29 years. Adaptive hormones were identified by spectrophotometry on the samples of urine that was collected in the morning, 15 minutes before the game and 15 minutes after the game, and in the evening. The hormones were identified by the method of spectrophotometry. The results show that during the game round disturbance of circadian rhythm of adaptive hormones secretion is characterised by fluctuations. The maximum level of 17-oks was observed just before the game and during the game — at 15–18 hours. The maximum level of adrenaline was detected before the game, but after the game it is considerably reduced. The highest levels of norepinephrine and catecholamine index were recorded after the game. Differences of these oscillations depending on the strength and success of the game were shown.
