Relación entre la velocidad media propulsiva y eficiencia de la acción motriz del ataque en Voleibol

Abstract

The main objective of this research was to determine the relationship between the average propulsive speed and the effectiveness of the attack in volleyball players belonging to the USTA Tunja, to evaluate the average speed the AXON JUMP jump platform was used, which consists of a device to measure the height and speed of an athlete's jump in real time, likewise body measurement instruments were implemented, such as the stadiometer and the electrical bioimpedance scale, in order to have a better characterization of the population, the assessment of the technical gesture was carried out through the KINOVEA software, obtaining relevant data in the analysis of the technical gesture of the attack. The data were stored and analyzed in the SPSS STADISTIC 30.0.0 program. After having carried out an exhaustive analysis and respective evaluations of the collected data, it is possible to deduce that the volleyball players of the Santo Tomás University have a good performance in jumping and propulsive speed compared to university volleyball players evaluated in studies highlighted in the present study, but with significant differences between them; The average college-level player achieves a vertical jump of 53.02 cm, compared to the maximum jump achieved by college athletes from Santo Tomas University, which is 59.30 cm, performed by subject #1. Similarly, the subject with the lowest jumping ability was #4 with a maximum jump of 32.10 cm. However, the average jumping ability of the total population evaluated was 44.40 cm. With the aforementioned, it can be determined that athlete #1 is above average values. Some exceeded the average jump compared to previous studies, while others were below, reflecting variability in their physical abilities. The good performance in the Abalakov jump, related to the technical gesture of the attack, stands out. Although the athletes have a good ability to generate power, deficiencies were identified in aspects such as space-time perception, wrist placement, and landing. These points can be improved with the data obtained, which will allow for more effective training planning. Finally, it is concluded that average propulsive speed is crucial for attack execution, since players with higher speed showed better mechanical performance, which could improve attack effectiveness and overall player performance.
