Resumo: This study aims to verify the visual behavior using the analysis of both quan-tity and duration of visual fixation and the quality of the DM in volleyball players and athletes from other sports in extreming attacking (EA), cental attack (CA), setting (SE) and blocking (BL) situations. The visual behavior was analyzed during the evaluation of volleyball scenes with an eye-tracking system. The first decision the volunteer voiced was determined as his solution for the scene presented and it was used for analyzing the DM quality. For the quantity of visual fixations, the independent t-test was used to compare groups in the following situtations, EA, SE and BL. For analyzing the quality of DM, the chi-square test of proportions was used. Moreover, for the analysis of the duration and number of visual fixations, the independent t test was addopet (or Mann-Whitney test when some of the assumptions were not met for parametric analysis). Significantly higher values were observed on duration of visual fixations in athletes from other sports comparing to volleyball players at CA (p = 0.042). The DM were significantly different in EA (p = 0.024) and CA (p = 0.001) between groups, showing higher frequency of correct answers for the volleyball players. We conclude that volleyball players perform faster fixations in situations of CA and take more correct decisions in attacking situation (EA and CA) compared to athletes from other sports.

Analisou-se o comportamento visual durante a avaliação de cenas de voleibol com o eye-tracking (sistema de rastreamento ocular). A primeira decisão do voluntário verbalizada foi considerada como a sua solução para a cena apresentada e foi utilizada para analisar a qualidade da TD. Para a quantidade de fixações visuais, o teste t independente foi utilizado para comparar os grupos nas seguintes situações, AE, LE e BL. Para a análise da qualidade da TD, utilizou-se o teste qui-quadrado de proporções. Já para a análise da duração e número de fixações visuais recorreu-se ao teste t independente (ou teste de Mann-Whitney quando algum dos pressupostos para a análise paramétrica não foi atendido). Valores significativamente maiores foram encontrados na duração das fixações visuais em atletas de outros esportes quando comparados a atletas de voleibol no AC (p=0,042). As TDs foram significativamente diferentes em AE (p=0,024) e AC (p=0,001) entre os grupos, mostrando maior frequência de respostas corretas para os atletas de voleibol. Conclui-se que os atletas de voleibol realizam fixações mais rápidas em situações de AC e tomam decisões mais corretas em situações de ataque (AE e AC) em comparação com os atletas de outros esportes.Universidade Federal de Minas GeraisBrasilEEF - DEPARTAMENTO DE ESPORTESUFMG2024-04-17T18:34:24Z2024-04-17T18:34:24Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf10.5007/1980-0037.2016v18n6p6381980-0037http://hdl.handle.net/1843/67335porRevista Brasileira de Cineantropometria e Desempenho HumanoHenrique de Oliveira CastroGibson Moreira PraçaGustavo de Conti Teixeira CostaGustavo Ferreira PedrosaPablo Juan Grecoinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMG2024-04-17T20:26:13Zoai:repositorio.ufmg.br:1843/67335Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oairepositorio@ufmg.bropendoar:2024-04-17T20:26:13Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
