Differences in Technical Development and Playing Space in Three UEFA Champions Leagues
2021
[Abstract] The analysis of football grows exponentially, with many researchers adopting it as an object of study. The thematic range that addresses it, as well as the different methodologies used, are of a very different nature—physical, psychological, technical, tactical—enriching every day the knowledge, and understanding of the game itself. The objective of this study has been to identify the differences between the different styles of play that lead to becoming the champion of the UEFA Champions League in the last 3 years of the pre-COVID stage, by analyzing the spatial performance developed, the association between the players that make up the different lines of the game system and the…
Identification of Explanatory Variables in Possession of the Ball in High-Performance Women’s Football
2021
[Abstrac] Women’s football is a phenomenon that is experiencing an unstoppable increase in recent years. The objective of this study was to analyze how ball possessions are performed in highperformance women’s football. For this, the 52 matches played by all the national teams participating in the Women’s World Cup 2015 were analyzed. A total of 3740 ball possessions were examined. Using the “move outcome” variable as a reference criterion, a statistically significant relationship was found between possessions that ended in success and possessions that have failed. Specifically, the successful possessions were those that were made in the offensive zone, with a clear intention to progress to…
Identification of Defensive Performance Factors in the 2010 FIFA World Cup South Africa
2016
The aim of this study was to determine the efficacy of defensive play in elite football, to identify variables associated with the direct recovery of ball possession, and to propose a model for predicting the success of defensive transitions. We analyzed 804 transitions in the final stages of the Fedération Internationale Football Association (FIFA) World Cup 2010, and investigated the following variables using univariate, bivariate, and multivariate analyses: duration of defensive transition, possession loss zone, position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, time of the match, position of defense, zone in which t…
El papel que desempeñan las teorías en la Biología
2006
Resumen basado en el de la publicación Resumen en inglés Se trata de enfatizar la importancia del término interpretación de la teoría y su uso indebido en la educación científica. También se discute la conveniencia de enseñar biología como una ciencia hipotético-deductiva, y el papel que el mapeo conceptual juega en estos elementos. ESP
Multivariate analysis of defensive phase in football: Identification of successful behavior patterns of 2014 Brazil FIFA World Cup
2021
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…
Podria Descartes embarcar en la nau de Neurath?
1999
En aquest article Josep Lluís Blasco reflexiona sobre els suggeriments epistemològics de Descartes, des de la perspectiva de la teoria del coneixement del segle XX, i es pregunta fins a quin punt es pot considerar que Descartes inaugurà l’epistemologia moderna i quina és la vigència del seu legat. Enceta la seua anàlisi amb la metàfora de la nau d’Otto Neurath, segons la qual el coneixement científic no té uns fonaments sòlids perquè és un constructe teòric que s’ha de revisar de manera contínua, i afegeix la modificació que en fa Quine en situar a la mateixa nau la filosofia i la ciència. Blasco examina si Descartes podria embarcar en dita nau, i conclou que la resposta no és tan senzilla …
Offensive Transitions in High-Performance Football: Differences Between UEFA Euro 2008 and UEFA Euro 2016
2019
[Abstract] Coaches, footballers and researchers agree that offensive transitions are one of the most important moments in football today. In a sport where defense over attack dominates, with low scores on the scoreboard, the importance of these actions from the offensive point of view becomes very important. Despite this, scientific literature is still very limited on this topic. Therefore, the objectives set out in the present investigation have been two: first, by means of a proportion analysis and the application of a chisquare test, it was intended to describe the possible differences between the offensive transitions made in the UEFA Euro 2008 and UEFA Euro 2016; then, through differen…
Documentació i Metodologia Científica. Grau Farmácia
2013
El document forma part dels materials docents programats mitjançant l'ajut del Servei de Política Lingüística de la Universitat de València. El que habitualment es denomina “mètode científic” és un conjunt de pràctiques teòriques i experimentals molt diverses. Les seues característiques varien al llarg del temps i l'espai, així com a través de les disciplines i les diverses especialitats de la ciència. Fins i tot dins d'una mateixa disciplina científica, existeixen punts de vista diversos al voltant dels procediments més adients per produir nous coneixements suficientment contrastats. Per això, s'empra l'expressió “metodologia científica” per fer referència a l'heterogeni conjunt d'estratèg…
La influencia del estado del partido en la posesión del balón en el fútbol femenino de alto rendimiento
2020
[Abstract] The objective of this study was to examine the effect of the situational match status variable on the ball possession of the teams that participated in the 2015 FIFA Women’s World Cup. The 52 games played during the championship have been collected, and 3,740 ball possessions made by the teams were analyzed. The teams have been divided into successful and unsuccessful. Three types of analysis have been carried out: a univariate analysis for both groups with the categorical and continuous variables selected; a bivariate analysis, using chi-square tests and the exact Fischer test; and finally, a multivariable technique such as the decision trees was incorporated. The available resu…
