DYNAMIC CONTROL OF FUNCTIONAL FITNESS OF VOLLEYBALL PLAYERS THROUGH HEART RATE VARIABILITY ANALYSIS
Abstract
Abstract. Aim. The paper aims to identify the features of heart rate variability of volleyball players during the season depending on their court positions. Materials and methods. The study involved volleyball players (Russian Volleyball Super League) with different court positions: outside hitters, opposite hitters, middle blockers, and setters. Cardiac rhythm was recorded with the Varicard 2.8 system (Ryazan). Time and spectral domain indices were calculated with the Iskim 6.2 software. Results. The direction and gree of HRV changes were identified depending on court positions. The results obtained can be used for personal recommendations for optimal physical fitness and more efficient training. Conclusion. In volleyball, court positions should be allocated with respect to the type of autonomous regulation. Functional fitness levels allow to identify appropriate physical load, which is of particular importance when it comes to strength training.
