The “GDV Bio-Well” computer appliance used in the study yields a sufficiently accurate estimation of the parameters of the psychophysiological state of athletes. Through investigating the fluorescent fingertip images, which dynamically change with emotional and energy states, one can identify areas of congestion of energy in the whole system. “GDV Bio-Well” computer appliance enables prompt monitoring of the process of adaptation to the high athletes during the pre-competition and competition periods and timely implementation of the necessary corrective measures.
