Análise do desempenho de saltos de uma equipe feminina de voleibol profissional ao longo de uma temporada competitiva

Abstract

The present study aimed to compare the vertical jump performance of female athletes from Praia Clube between the first and second rounds of the Brazilian Women's Volleyball Super League regular season, considering only jumps performed during official matches. This is a quantitative, descriptive, and comparative study based on data collected using a vertical jump monitoring system. The sample consisted of 12 professional athletes, and 21 matches were analyzed, including 10 games from the first round and 11 from the second round. Training sessions, playoff matches, and jumps below 15 cm were excluded, resulting in the removal of 777 jumps. Data were analyzed using descriptive and inferential statistics, applying the Mann-Whitney test (p < 0.05). The results showed a significant increase in mean jump height from the first to the second round (38.25 ± 13.63 cm vs. 40.19 ± 13.45 cm; p < 0.05), with no significant differences in jump frequency per match or maximum values (TOP_1 and TOP_10). It is concluded that there was an improvement in neuromuscular capacity throughout the competition, while maintaining stability in external load. Vertical jump monitoring proved to be an important tool for assessing physical performance in volleyball athletes.
