The influence of the auto-training technique on the excretion of catecholamine in archers under different psychological states

The aim of this study is to analyse the improvement of the archer's readiness based on a specialized psycho-regulatory training technique using biochemical methods of controlling the excretion of catecholamines. The sample consisted of fifteen archers (KMS and MS) aged between 18 and 20 (mean 19.3 +/- 0.28), divided into two groups (experimental and control). Before each training, the archers of the experimental group used the proposed technique of increasing the level of psychological readiness. The biochemical examination of the archers was carried out in two stages: during training and during competitions. Before physical activity, urine samples of the archers were taken, in which the content of the catecholamines was determined by the liquid chromatography in the columns. The application of the auto-training technique during the archer's meeting sessions did not change the excretion of catecholamine hormones. Whereas the systematic application of psycho-regulatory techniques during active competitions led to a decrease in the A concentration and an increase in the NA concentration in the experimental group archers (p < .001). The variance analysis established a significant contribution of the auto-training technique to changes in the excretion of Adrenalin (56.1% (p < .01)) and Noradrenaline (72.7% (p < .001)). The contribution of unaccounted factors to the performance of the archers remained significant but was unreliable. The systematic application of the method of increasing the level of psychological readiness allows you to adjust the level of catecholamines and, accordingly, positively influence the athlete's performance during active competitions.
