Resumo
A observação e análise no desporto têm sido cada vez mais utilizadas. Nas últimas
décadas tem se assistido a uma grande evolução como ferramentas para avaliar objetivamente
o desempenho desportivo, tanto nas modalidades individuais como nas coletivas. Sendo ausente
a investigação e estudos em observação e análise técnico-tática na modalidade de Corfebol, este
trabalho é tido como pertinente e pretende contribuir para a evolução da modalidade em
Portugal. Esta dissertação tem como objetivos: a) construir e validar um sistema de observação
e análise técnico-tática, do ataque, na modalidade de Corfebol (SOATTAC), que permita
fornecer informações relevantes para o treino e competição; b) estudar a eficácia de dois
sistemas ofensivos utilizados pela Seleção Portuguesa de Corfebol, no Campeonato da Europa
de 2018, 3:1 com assistência e ressalto dinâmico ou 2:2 com ressaltador fixo.
O trabalho foi desenvolvido em duas fases 1ª fase: a) levantamento dos critérios e
comportamentos tendo como base a literatura, a observação de vários jogos, a experiência
enquanto atleta internacional e Selecionadora Nacional. A revisão crítica da literatura permitiu
selecionar artigos que desenvolvem e validam instrumentos de observação e análise técnico tática de modalidades coletivas, que serviram de referência para a elaboração deste trabalho; b)
recolhida a opinião de peritos sobre a pertinência das variáveis em relação aos aspetos
fundamentais do jogo com a aplicação de um questionário. Após a definição de critérios e das
categorias foi realizado um questionário a 8 peritos e os dados foram considerados, na sua
maioria, confiáveis; c) construção de um sistema de categorias com códigos; 2ª fase: a)
aplicação na observação e análise do ataque, de Portugal, no Campeonato da Europa de 2018.
Foi utilizado o Software Lince para a recolha dos dados e para a sua análise o Programa IBM
SPSS. A aplicação incidiu em 231 ações ofensivas, de três jogos de Portugal, e foi verificado
que este sistema é de grande utilidade pois permite fazer uma análise muito completa e precisa
de vários indicadores de jogo, no ataque, e é fiável. Foi ainda possível obter, com a aplicação
do instrumento observacional, a eficácia de dois sistemas ofensivos, em que o 3:1 com
assistência (ressalto dinâmico) mostrou-se mais eficaz que o 2:2 com ressaltador (ressalto fixo)
com uma diferença considerável, 38% e 13%, respetivamente.
Sugiro que no futuro seja criado um Sistema de Observação e Análise Técnico-Tática
que contemple também em conjunto os aspetos defensivos.
Observation and analysis in sports have been increasingly used. In the last decades, there has been a significant evolution in using them as tools to objectively evaluate sports performance, both in individual and collective sports. According to the absence of research and studies in the area of observation and technical-tactical analysis in Korfball, this work is considered relevant and it intends to contribute to the evolution of this sport in Portugal. This dissertation aims to: a) build and validate a system of observation and technical-tactical analysis, of the attack of Korfball (SOATTAC), that allows providing relevant information for the training and competition; b) study the effectiveness of two offensive systems used by the Portuguese Korfball National Team, in the 2018 European Championship, 3:1 with assistance and dynamic rebound or 2:2 with a fixed rebounder. The work was developed in two phases: 1st phase: a) survey of criteria and behaviors based on literature, observation of several games, and experience as an international athlete and National Coach. The critical review of the literature allowed to select articles that develop and validate instruments of observation and technical-tactical analysis of collective modalities, which served as a reference for the elaboration of this work; b) collected the opinion of experts on the relevance of the variables concerning the fundamental aspects of the game with the application of a questionnaire. After defining criteria and categories, a questionnaire to experts was carried out (n=8) and the data were mostly considered reliable; c) construction of a system of categories with codes; 2nd phase: a) application in the observation and analysis of the Portuguese team attack in the 2018 European Championship. Lince Software was used for data collection and the IBM SPSS Program was used for analysis. The application focused on 231 offensive actions, from three games in Portugal, and it was verified that this system is very useful because it allows a very complete and accurate analysis of several game indicators in the attack, and it is also reliable. It was also possible to obtain, with the application of the observational instrument, the effectiveness of two offensive systems, in which the 3:1 with assistance (dynamic rebound) was more effective than the 2:2 with rebounder (fixed rebound) with a considerable difference, 38%, and 13%, respectively. I suggest that, in the future, should be created a Technical-Tactical Observation and Analysis System that also includes defensive aspects together.
