          Abstract

          RESUMEN El objetivo del presente estudio fue determinar el grado de relación (activación e inhibición) inter-líneas y respecto a su rival que presenta la Selección Española de fútbol cuando se encuentra en posesión del balón. Para ello se analizaron los partidos de España durante la UEFA Euro 2012 (6861 multieventos han sido codificados). Se ha utilizado un instrumento de observación ad hoc, formado por 8 criterios y 96 categorías, que permitieron registrar cuatro líneas o niveles de organización: POR (portero), DEF (defensas), CEN (centrocampistas) y DEL (delanteros), así como también su relación con el rival (JR). Los datos fueron sometidos a un análisis de coordenadas polares, utilizando cada línea como conducta focal. Los resultados muestran la relación y cohesión inter-líneas que presenta el equipo, así como la activación de jugadores rivales. Esto nos permite conocer el componente táctico de la selección española y su relación con los jugadores rivales. También se ha destacado la eficacia de la metodología observacional como un filtro metodológico óptimo para el estudio del comportamiento espontáneo de los jugadores, incluyendo poderosos técnicas como el análisis de coordenadas polares. Los estudios futuros pasan por profundizar en la realidad del jugador en particular, para a continuación construir la compleja estructura que conforman las interrelaciones entre los diferentes integrantes de un equipo. Sin duda esto redundará en un mejor desempeño de la realidad del fútbol en los campos de juego.

          ABSTRACT The objective of the present study was to determine the degree of inter-line relation (activation and inhibition) and with respect to its rival that presents the Spanish Selection of soccer when in possession of the ball. For this we analyzed the matches of Spain during the UEFA Euro 2012 (6861 multi-events have been coded). An ad hoc observation instrument, consisting of 8 criteria and 96 categories, was used to record four lines or levels of organization: POR (goalkeeper), DEF (defenses), CEN (midfielders) and DEL (forward). also his relationship with the rival (JR). The data were subjected to polar coordinate analysis using each line as focal behavior. The results show the relationship and cohesion inter-lines that the equipment presents, as well as the activation of rival players. This allows us to know the tactical component of the Spanish team and its relationship with the rival players. The effectiveness of observational methodology has also been highlighted as an optimal methodological filter for the study of players' spontaneous behavior, including powerful techniques such as polar coordinate analysis. Future studies go deep into the reality of the player in particular, and then build the complex structure that make up the interrelationships between the different members of a team. Undoubtedly this will result in a better performance of the reality of football on the playing fields.

          RESUMO O objetivo do presente estudo foi determinar o grau de relação inter-line (ativação e inibição) e em relação ao seu rival que apresenta a seleção espanhola de futebol quando em posse da bola. Para isso, analisamos os jogos de Espanha durante a UEFA Euro 2012 (6861 multi-eventos foram codificados). Um instrumento de observação ad hoc, composto por 8 critérios e 96 categorias, foi usado para registrar quatro linhas ou níveis de organização: POR (goleiro), DEF (defesas), CEN (meio-campo) e DEL (para frente). também sua relação com o rival (JR). Os dados foram submetidos a análise de coordenadas polares usando cada linha como comportamento focal. Os resultados mostram as inter-linhas de relacionamento e coesão que o equipamento apresenta, bem como a ativação de jogadores rivais. Isso nos permite conhecer o componente tático da equipe espanhola e sua relação com os jogadores rivais. A eficácia da metodologia observacional também foi destacada como um ótimo filtro metodológico para o estudo do comportamento espontâneo dos jogadores, incluindo técnicas poderosas como a análise de coordenadas polares. Estudos futuros abordam a realidade do jogador em particular e, em seguida, criam a estrutura complexa que compõe as inter-relações entre os diferentes membros de uma equipe. Sem dúvida, isso resultará em um melhor desempenho da realidade do futebol nos campos de jogo.

            Analysis of high intensity activity in Premier League soccer.

            The aim of the present investigation was to provide a detailed analysis of the high intensity running activity completed by elite soccer players during match-play. A further aim of the study was to evaluate the importance of high intensity running activity to overall team success. Observations on individual match performance measures were undertaken on 563 outfield players (median of 8 games per player; range=1-57) competing in the English Premier League from 2003/2004 to 2005/2006 using a computerised tracking system (Prozone, Leeds, England). High intensity activities selected for analysis included total high intensity running distance (THIR), total sprint distance (TSD) and the number and type of sprints undertaken. Total high intensity running distance in possession and without possession of the ball was also analysed. The THIR was dependant upon playing position with wide midfield (1,049+/-106 m) and central defenders (681+/-128 m) completing the highest and lowest distance respectively (p<0.001). High intensity activity was also related to team success with teams finishing in the bottom five (919+/-128 m) and middle ten (917+/-143 m) league positions completing significantly more THIR compared with teams in the top five (885+/-113 m) (p=0.003). The THIR and TSD also significantly declined during the 2nd half with the greatest decrements observed in wide midfield and attacking players (p<0.05). Both positional differences in high intensity activity and the observed change in activity throughout the game were also influenced by team success (p<0.05). The results of the present study indicate that high intensity activity in elite soccer match-play is influenced by both playing position and previous activity in the game. These activity patterns are also dependant upon success of the team. This may indicate that overall technical and tactical effectiveness of the team rather than high levels of physical performance per se are more important in determining success in soccer.

              The Use of Match Statistics that Discriminate Between Successful and Unsuccessful Soccer Teams

              Three soccer World Cups were analysed with the aim of identifying the match statistics which best discriminated between winning, drawing and losing teams. The analysis was based on 177 matches played during the three most recent World Cup tournaments: Korea/Japan 2002 (59), Germany 2006 (59) and South Africa 2010 (59). Two categories of variables were studied: 1) those related to attacking play: goals scored, total shots, shots on target, shots off target, ball possession, number of off-sides committed, fouls received and corners; and 2) those related to defence: total shots received, shots on target received, shots off target received, off-sides received, fouls committed, corners against, yellow cards and red cards. Discriminant analysis of these matches revealed the following: (a) the variables related to attacking play that best differentiated between winning, drawing and losing teams were total shots, shots on target and ball possession; and (b) the most discriminating variables related to defence were total shots received and shots on target received. These results suggest that winning, drawing and losing national teams may be discriminated from one another on the basis of variables such as ball possession and the effectiveness of their attacking play. This information may be of benefit to both coaches and players, adding to their knowledge about soccer performance indicators and helping to guide the training process.
