Resumo(s)
No âmbito da Unidade Curricular de Estágio do 2.º ciclo em Ciências do Desporto – Treino Desportivo, da Universidade da Beira Interior (UBI), foi realizado um estágio curricular no Académico de Viseu Futebol Clube (AVFC), na equipa de Sub-23 que competiu na Liga Revelação. Durante o estágio, o estagiário integrou a equipa técnica, desempenhando funções de treinador estagiário e analista, no qual foram desenvolvidas competências de análise aos adversários. Ficou igualmente responsável pela gravação de treino e jogo, a fim de ter o controlo e registo de todo o processo. O futebol moderno tem evoluído com recurso a métricas de desempenho, como o xG (golos esperados), que permitem otimizar o rendimento individual e coletivo. Com o objetivo de potenciar o processo de treino, realizou-se um estudo que investigou a correlação do xG com diferentes variáveis físicas e indicadores-chave de desempenho, considerando variáveis contextuais como fase da época, local do jogo, resultado e nível do adversário. Foram analisados 29 jogos da equipa Sub-23, utilizando dados da plataforma Wyscout e informações físicas obtidas através de dispositivo GPS. Os resultados foram comparados por fase da época (1.ª fase vs 2.ª fase), local do jogo (casa vs fora), resultado (vitória vs empate vs derrota) e nível do adversário (alto vs médio vs baixo). Posteriormente, estabeleceram-se correlações entre o xG e as diversas variáveis, tendo em conta os distintos contextos. Os resultados indicaram que as variáveis ofensivas apresentam maior correlação com o xG, variando significativamente consoante o contexto e possivelmente entre equipas. Concluise que, embora o xG seja uma ferramenta eficaz para avaliar o desempenho ofensivo, a sua interpretação deve ser contextualizada para otimizar o processo de treino.
As part of the Internship Course Unit of the 2nd cycle in Sports Sciences – Sports Training, at the University of Beira Interior (UBI), an internship was carried out at Académico de Viseu Futebol Clube (AVFC), in the Under-23 team that competed in the Liga Revelação. During the internship, the intern joined the technical team, performing the duties of trainee coach and analyst, in which he developed skills in analysing opponents. He was also responsible for recording training sessions and matches in order to monitor and record the entire process. Modern football has evolved with the use of performance metrics, such as xG (expected goals), which allow for the optimisation of individual and collective performance. With the aim of enhancing the training process, a study was conducted to investigate the correlation between xG and different physical variables and key performance indicators, considering contextual variables such as stage of the season, location of the match, result and level of the opponent. Twenty-nine matches of the Under-23 team were analysed, using data from the Wyscout platform and physical information obtained via GPS. The results were compared by stage of the season (1st stage vs. 2nd stage), location of the game (home vs. away), result (win vs. draw vs. loss) and level of the opponent (high vs. medium vs. low). Subsequently, correlations were established between xG and the various variables, taking into account the different contexts. The results indicated that offensive variables show a higher correlation with xG, varying significantly depending on the context and possibly between teams. It was concluded that, although xG is an effective tool for assessing offensive performance, its interpretation must be contextualised in order to optimise the training process.
