Resumo: | Aim: This study aimed to validate an observational instrument of footvolley's tactics (FtVi) and use it in an empirical investigation of tactical-technical tendencies in high-level footvolley matches. Methods: The validation followed five steps: i) design; ii) pilot analysis; iii) content validation; iv) reproducibility; v) empirical study. We analyzed women's and men's matches from the Brazilian Footvolley's Circuit - 2019. Content validity and reproducibility were evaluated with Aiken's V and Cohen's Kappa coefficients, respectively. The Chi-square test of independence was applied to infer about sexes' tactical tendencies. Results: The FtVi encompassed the following categories: i) match context; ii) game situation; iii) rally's outcome; iv) game actions. Aiken's V coefficients were greater than 0.90. Intraand inter-observer reproducibility presented near perfect agreement (0.92; 0.89). Assessment of the game dynamics did not point to a significantly greater proportion of complex II (w: 60.6%; m: 57.5%) than complex I (w: 39.4%, m: 42.5%), p > 0.05. The median rallies' length was close to three court exchanges for both sexes. The attack efficiency did not present significantly greater frequency of continuation attacks (w: 70.4.5%, m: 66.8%) in relation to points (w: 19.4. %, m: 22.9%), p > 0.05. For all attacks and scoring attacks, backcourt and net zone were respectively more frequent. Most frequent techniques were different between sexes and all related to upper body (women - head: 29.7%, shoulder: 23.0%; men - chest: 30.3%, head: 24.8%). Conclusion: FtVi successfully supported gathering evidence about footvolley's tactics, which may help coaches' practice. The absence of hands-arm use in the footvolley's techniques may contribute both to longer rallies since steep attacks are limited and, counter-intuitively, to a greater emphasis on upperbody than foot techniques. |

Métodos: A validação seguiu cinco etapas: i) desenho; ii) análise piloto; iii) validação de conteúdo; iv) reprodutibilidade; v) estudo empírico. Nós analisamos partidas femininas e masculinas do Circuito Brasileiro de Futevôlei - 2019. A validade de conteúdo e a reprodutibilidade foram avaliados com os coeficientes V de Aiken e Kappa de Cohen, respectivamente. O teste Qui-quadrado de independência foi aplicado para inferir sobre as tendências táticas dos sexos. Resultados: O FtVi englobou as seguintes categorias: i) correspondência contexto; ii) situação de jogo; iii) resultado do rali; iv) ações do jogo. Os coeficientes V de Aiken foram superiores a 0,90. A reprodutibilidade intra e interobservador apresentou concordância quase perfeita (0,92; 0,89). A avaliação da dinâmica do jogo fez não apontam para uma proporção significativamente maior de complexo II (w: 60,6%; m: 57,5%) do que complexo I (w: 39,4%, m: 42,5%), p > 0,05. A duração média dos comícios foi próxima de três trocas de quadra para ambos os sexos. A eficiência do ataque fez não apresentam frequência significativamente maior de ataques continuados (w: 70,4,5%, m: 66,8%) em relação aos pontos (w: 19,4. %, m: 22,9%), p > 0,05. Para todos os ataques e ataques de gol, a zona de defesa e a zona de rede foram respectivamente mais frequentes. As técnicas mais frequentes foram diferentes entre os sexos e todas relacionadas com a parte superior do corpo (mulheres - cabeça: 29,7%, ombro: 23,0%; homens - tórax: 30,3%, cabeça: 24,8%). Conclusão: A FtVi apoiou com sucesso a coleta de evidências sobre as táticas do futevôlei, o que pode ajudar na prática dos treinadores. A ausência do uso mãos-braços nas técnicas do futevôlei pode contribuem tanto para rallies mais longos, uma vez que os ataques íngremes são limitados, como, contra-intuitivamente, para uma maior ênfase na parte superior do corpo do que nas técnicas de pé.Universidade Estadual Paulista - Câmpus de Rio Claro2024-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionDocumento Avaliado por Paresapplication/pdfhttps://www.periodicos.rc.biblioteca.unesp.br/index.php/motriz/article/view/1835710.5016/s1980-6574e10240082Motriz.
