Women’s football is currently a phenomenon in expansion, both in the number of practitioners and federative records. Scientific research must be at the forefront of this growth, proposing solutions with empirical support that help improve performance not only during training but also during competition. The objective of this study was to propose a multivariate model based on the decision tree technique, with the aim of classifying and predicting the criteria that modulated the attack depending on the part of the match (either the first or second part). To do this, 6063 attacks from the two most recent world championships have been collected and analysed. The available results indicate that, although more attacks occur during the first part, it is in the second part when the goals are scored. In addition, the presented model confirms that the most successful attacks (goal, shot or sending to the area) occur with the score winning or losing, and with a duration of less than 20 seconds. The results of this study can help female soccer coaches to improve the training process of offensive actions and attack

El fútbol femenino está experimentando un notable crecimiento desde hace unos años a esta parte. La investigación científica debe estar a la vanguardia de este crecimiento, proponiendo recomendaciones con aval científico que ayude a mejorar la toma de decisiones en el campo aplicado. En el presente estudio se analiza una de las variables contextuales más estudiadas en fútbol masculino de alto rendimiento, como es la influencia del resultado parcial en las posesiones de balón. Para ello, se han recogido y analizado 6063 posesiones de balón realizadas durante los dos campeonatos del mundo más recientes, el FIFA Women´s World Cup 2015 y 2019. Para ello, se han llevado a cabo dos tipos de análisis: en primer lugar, un análisis univariado para conocer incidencia, eficacia y prácticas habituales de este tipo de acciones; en segundo lugar, a nivel bivariado, se pretende conocer la posible influencia del resultado parcial (ganando, empatando o perdiendo) en los diferentes criterios considerados. Los resultados disponibles indican que las posesiones de balón son acciones que tienen una alta incidencia durante los partidos, pero con un índice de eficacia muy reducido). A nivel bivariado, el resultado parcial sí modula el comportamiento de ciertos criterios como la forma de inicio de la posesión, la duración, el número de pases o el contexto de interacción. Los resultados del presente estudio pueden ayudar a las entrenadoras de fútbol durante su labor al frente de los equipos., Women's football has been experiencing notable growth for a few years now. Scientific research must be at the forefront of this growth, proposing scientifically backed recommendations that help improve decision-making in the applied field. In the present study, one of the most studied contextual variables in high performance men's soccer is analyzed, such as the influence of the partial result on ball possessions. To do this, 6063 ball possessions made during the two most recent world championships, the FIFA Women's World Cup 2015 and 2019, have been collected and analyzed. To do this, two types of analysis have been carried out: firstly, a univariate analysis to find out the incidence, efficacy and habitual practices of this type of actions; secondly, at a bivariate level, it is intended to know the possible influence of the partial result (winning, drawing or losing) on the different criteria considered. The available results indicate that ball possessions are actions that have a high incidence during matches, but with a very low efficiency rate). At a bivariate level, the partial result does modulate the behavior of certain criteria such as the manner in which possession begins, the duration, the number of passes or the context of interaction. The results of this study can help soccer coaches during their work in charge of the teams, O futebol feminino vem experimentando um crescimento notável há alguns anos. A pesquisa científica deve estar na vanguarda desse crescimento, propondo recomendações cientificamente respaldadas que ajudem a melhorar a tomada de decisões no campo aplicado. No presente estudo, analisa-se uma das variáveis contextuais mais estudadas no futebol masculino de alto rendimento, como a influência do resultado parcial na posse de bola. Para isso, foram coletadas e analisadas 6.063 posses de bola feitas durante os dois últimos campeonatos mundiais, a Copa do Mundo Feminina da FIFA 2015 e 2019. Para isso, dois tipos de análise foram realizados: em primeiro lugar, uma análise univariada para conhecer a incidência, eficácia e práticas habituais deste tipo de ação; em segundo lugar, a nível bivariado, pretendese conhecer a possível influência do resultado parcial (vitória, empate ou derrota) nos diferentes critérios considerados. Os resultados disponíveis indicam que as posses de bola são ações com alta incidência durante as partidas, mas com baixíssimo índice de eficiência). A nível bivariado, o resultado parcial modula o comportamento de certos critérios como a forma de início da posse, a duração, o número de passes ou o contexto da interação. Os resultados deste estudo podem auxiliar os treinadores de futebol durante seu trabalho à frente das equipes.

The aim of this study was to identify variables associated with direct recovery of the ball during defensive transitions in elite soccer and to propose a model with certain guarantees of success based on a multivariate analysis in which binary logistic regression was used to explore interaction between variables. 1,722 defensive transitions were analysed in the final stages of the FIFA World Cup 2014 in Brazil and investigated the following variables: duration of defensive transition; possession loss zone; position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, period of the match, position of defence line, zone in which the offensive transition ends, match status, and outcome of the defensive transition. The variables found to significantly associated with ball recovery were the area of the pitch in which the ball is lost prior to the transition (p < .05), the duration of the transition (p < .01), the position of the defence lines (p < .01), the zone in which the transition ends (p < .001), and end spatial interaction configuration (p < .001). The model that provided the best guarantees of recovering possession was characterized by a defensive transition lasting 15 seconds or less that ends in the holding midfield with the attacking team under pressure
