    Influencia de la ubicación de las miniporterías y los comodines en la enseñanza del fútbol
    (Universidad de Murcia: servicio de publicaciones, 2025) Martín-Barrero, Alberto; Pérez-Hierro, Carlos; Flores-Rodríguez, José; Sin departamento asociado
    This study analysed the influence of the location of floaters players and mini-goalposts on the technical-tactical behaviour of players in training tasks in grassroots football. The tactical behaviour of 12 players (11.6 ± .4 years old) belonging to the alevíncategory [U12]of a La Liga Santander team was analysed in 4 tasks (5vs 5 + 2 floaters players) with different constraints: i) floaters players and goalposts in the central area, ii) floaters players in the central area and goalposts in the side zone, iii) floaters players in the side zone and goalposts in the central area and iv) floaters players and goalposts in the side zone. The polar coordinates analysis showed different types of offensive and defensive tactical behaviour in the different tasks, highlighting the greater number of actions in the central area with floaters players and goalposts in the same area. On the other hand, it was highlighted that when the goalposts were located in lateral areas, on an offensive level the ball tended to be initiated in these areas, circulating through a greater number of areas of the field, through a greater number of passes and having greater variety and success in finishing. This would help to improve task design in relation to the type of behavior desired during training
