The definitive version is available at www.ingentaconnect.comThe aim of this study was to explore emergent patterns of game structure in male and female matches from elite soccer by using playing distances measured according to the ball location. Archive data based on carefully selected four male and four female matches from elite Spanish soccer seasons 2002-3, 2003-4 and 2004-5 were collected by help of AMISCO PRO® system. Differences across six ball locations were found in mean playing length (χ2 5=328.1 and 520.9, P<0.001) and playing width (χ2 5=39.6 and 26.9, P<0.001) from male and female matches, respectively. Both sexes displayed similar movements in playing length that vary with stretch-contraction-stretch patterns and in playing width that vary with opposite patterns of contraction-stretch-contraction, but these patterns varied to a significantly greater extent in male matches. For example, male matches (mean=44.93±8.34 m) produced significantly (U=128564.0, z=-8.2, P<0.001) longer playing width during transition phase in midfield compared with female matches (mean=41.80±8.00 m). Results suggest that female matches produced less favourable patterns of game structure with fewer penetration opportunities than male matches. Specific suggestions for coaching intervention were given. This study demonstrates the potential of analysing playing distances according to the ball location for studying patterns of game structure in real soccer matches.Seksjon for coaching og psykologi / Department of Coaching and Psycholog

Influencia del contexto deportivo en la formación de los futbolistas de la selección española de fútbol

This study seeks to determine the influence that sport context and its most important aspects have on the training process of elite soccer players, and the most effective way to control it to achieve sport success. Thus, this research took into account the view of eleven international elite players and directors of academies, fitness coaches, psychologists and sport doctors in the seven main soccer academies in Spain. Data were obtained through a qualitative methodology with the interview as an instrument of measurement. Sport context is one of the most influential dimensions in the training process of a soccer player. Sport training in a good soccer academy is key in achieving sport success, where the coach is its greatest exponent. The opportunities coaches provide their players as well as the comprehensive training they give them mean that talented players achieve success. Individual development is marked by the coordination of all the members of the soccer academy: psychologist, doctor, fitness coach and director

The half-time talk: A mixed-method examination of youth-elite football coaches’ behaviours and team-management strategies

Football, unlike some other team sports, includes limited game interruptions for coaches to easily communicate with players and affect their performance. However, a reduced number of studies have explored how coaches attempt to influence players during half-time. This study examined football coaches’ behaviours during half-time and their perceptions underpinning their talks’ delivery. Five Spanish coaches (Mage = 32.2, SD = 8.8) working for a La Liga academy were systematically observed during half-time talks (n = 20) and participated in a semi-structured interview each. Half-time talks were coded using a modified version of the Coach Analysis and Intervention System, and semi-structured interviews were analysed following thematic analysis procedures. Instruction and feedback were the most employed behaviours for four coaches, with younger age-group coaches employing greater divergent questioning and in-talk player participation. Furthermore, data suggested that coaches conferred with their staff, before entering the changing room and rapidly progressed from divergent to convergent questions and feedback and instruction. The team's ‘level of play’ was the most perceived relevant factor affecting the verbal and vocal strategies of coaches’ messages, albeit the score gained importance for coaches of older age-groups. This study is pioneering, examining how coaches attempt to influence their players during half-time talks of competitive youth football

La creación de conocimiento en los deportes de equipo. Sobre el tamaño de la muestra y la generalización de los resultados

La ciencia se ha incorporado de una manera definitiva al deporte. Las decisiones que toman los preparadores están soportadas cada vez más por el conocimiento científico. Al finalizar un entrenamiento o un partido, cualquier deportista traslada a los técnicos una enorme cantidad de datos de todo tipo. Si se ha utilizado un dispositivo de localización GPS, el preparador físico sabrá qué distancia ha recorrido cada jugador durante la sesión, a que velocidades, con qué frecuencia se han producido la acciones técnicotácticas, las aceleraciones y desaceleraciones, la potencia de golpeo,… Si además el club dispone de sistemas todavía más sofisticados de recogida de información podrá recopilar el número de pases, los lanzamientos, la distancia entre jugadores, los mapas de calor de cada jugador,… Incluso es posible que se interrogue al deportista acerca de su percepción subjetiva del esfuerzo o su estado de ánimo. Los grandes clubes deportivos son verdaderos centros de I+D+I, preocupados por investigar todos los aspectos que puedan mejorar el rendimiento de los deportistas. Cada equipo dispone de un pequeño ejército de analistas, preparadores físicos, fisioterapeutas, recuperadores, ayudantes,… que intentan aportar desde su parcela datos para incrementar la probabilidad de ganar.&nbsp
