Sensory equipment for monitoring and assessing the jumping ability of volleyball players.

: The objective of this research was to develop a sensor device to control and evaluate the jumping ability of elite volleyball athletes and to test its efficacy in a pedagogical experiment. : The study involved determining the pulsometric and respiratory parameters during test loads, indicative of the endurance and speed-strength aspects essential for volleyball performance. Additionally, the necessity for post-training and post-competition jump performance restoration via short-term relaxation exercises was identified.
