Methodology of Assessment of Athletes' Jumping Skills Using Electronic Equipment

Background and Study. Vertical jump performance is a critical factor in volleyball, significantly influencing actions like spiking, blocking, and serving. Accurate assessment of jump height is essential for optimizing training strategies, especially at the elite level. Purpose: The aim of this study was to evaluate the validity and reliability of a novel computerized diagnostic equipment (CDE-A, Patent No. 001144) designed for precise measurement of vertical jump height in volleyball players. Materials and Methods. The study involved the development and validation of the CDE-A system to assess vertical jump performance. Participants included elite volleyball players from the Uzbekistan national team, various club teams, and students from the State University of Physical Education and Sports of Uzbekistan. The system's accuracy and reliability were tested through rigorous procedures, including data storage and analysis capabilities for maximum jump height and functional performance. The research involved developing and testing a specialized device (CDE-A) to evaluate elite volleyball players' vertical jump capabilities. Participants included 18 athletes aged 13–14, 16 athletes aged 15–16, and 50 students from the Uzbekistan State University of Physical Education and Sports. Measurements were conducted across age groups and educational levels. A pedagogical experiment compared traditional training (control group, CG) with specialized exercises for agility and jumping endurance (experimental group, EG). Results. The CDE-A device demonstrated high reliability and precision in measuring vertical jump height. Key features include the capability to store maximal jump data in computer memory and analyze its functional significance for training and performance evaluation. The device enables coaches to monitor and enhance athletes' jump performance with greater efficiency and accuracy. Conclusions. This research highlights the utility of the CDE-A system for assessing and improving vertical jump capabilities in volleyball players across all age groups. The study underscores its potential to revolutionize training methodologies by providing coaches with reliable, evidence-based insights into athletes' performance. The findings offer a foundation for further advancements in jump height measurement technologies and their application in sports science. This study establishes the CDE-A as a valuable tool for sports performance evaluation, with implications extending to volleyball and other sports requiring explosive jump abilities.
