RAPID ANALYSIS OF REGULATORY MECHANISMS IN HIGHLY SKILLED VOLLEYBALL PLAYERS OF DIFFERENT POSITIONS IN A COMPETITIVE MACROCYCLE (BY DATA ON HEART RATE VARIABILITY)

Abstract

Aim. The authors aim to identify the hierarchy of the mechanisms of heart rhythm regulation in solving competitive problems among highly skilled volleyball players, depending on their positions. Materials and methods. A rapid analysis of the state of regulation centers at individual structural and functional levels was performed on highly skilled volleyball players of different positions (Super League and Major League A, Russian Championship): outside hitters (n = 8), liberos (n = 4), blockers (n = 8), opposites (n = 4), and setters (n = 4). Heart rhythm recording was performed with the Omega-Sport software and hardware complex (Dinamika, St. Petersburg, Russia). Results. Depending on the volleyball position, a different participation of the centers responsible for heart rhythm regulation was recorded in highly skilled volleyball players. Conclusion. Control over regulatory processes allows for maintaining the high performance of volleyball players throughout the entire competitive period.
