This is an excellent instrument, very convenient, easy to use and informative. I am using it both at the institute and on my travels and I find it very accurate and reliable.
The "GDV Bio-Well" computing device used in the study provides a sufficiently accurate estimate of the parameters of the psychophysiological state of athletes. Through investigation of fluorescent finger images, which dynamically change with emotional and health states, areas of system-wide health congestion can be identified. The “GDV Bio-Well” computing device allows rapid monitoring of the adaptation process to high-level athletes during the pre-competition and competition periods and the timely implementation of the necessary corrective measures.
