DESEMPENHO DE ATLETAS DE VOLEIBOL NO ALCANCE DO BLOQUEIO E NO ATAQUE

Abstract

The present Technical Report aimed to analyze the performance of university volleyball athletes in the execution of the vertical jump, with emphasis on block and attack reach. The study included 25 athletes—16 male and nine female—all members of the UFMS teams. This quantitative, descriptive, and cross-sectional research evaluated anthropometric variables and performance in three types of jumps: the squat jump (SJ), the countermovement jump without arm swing (CMJ), and the countermovement jump with arm swing (CMJA). Additionally, two vertical reach measurements were assessed: A1, corresponding to the maximum height reached by the athlete with one arm fully extended, and A2, referring to the maximum height reached with both arms fully extended. The results showed that male athletes presented higher averages of stature, body mass, and jump height, which was also reflected in superior attack and block reach. The CMJA stood out as the best-performing jump for both sexes, highlighting the relevance of intersegmental coordination in enhancing impulse production. It is concluded that the analysis of the performance of UFMS university athletes across different types of vertical jumps allowed for the objective identification of factors influencing block and attack reach. The findings demonstrate the importance of anthropometric characteristics and the mechanical efficiency of the jumps, especially the CMJA, for technical performance in volleyball. Key words: volleyball; vertical jump; attack reach; block reach; sports performance.
