    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

    El uso del ciclo del juego como variable pedagógica en las tareas de entrenamiento en fútbol
    (Universidad de Murcia, Servicio de Publicaciones, 2022) Martín Babarro, Alberto; Martínez Cabrera, Francisco Ignacio
    El objetivo de esta investigación es conocer el efecto que provoca en los comportamientos cinemáticos de los jugadores de fútbol la introducción, en el diseño de tareas, del ciclo completo del juego (cambios constantes de cambios de fases ataque-defensa y defensa-ataque). Se utilizaron jugadores (n=20) de un equipo de élite español (15.69±1.14 años; 64.84±6.04 kg. de peso; 1.71±0.5 m. de altura). Se compararon las diferentes variables cinemáticas (distancia total relativa, aceleraciones relativas, desaceleraciones relativas, carga relativa del jugador, velocidad máxima y potencia metabólica relativa) en dos tipos de tareas: a) tarea 1: con fase ofensiva y b) tarea 2: con fase ofensiva y defensiva. Los datos mostraron que hubo diferencias significativas (p<.05) en todas las variables excepto en las desaceleraciones relativas y la velocidad máxima. Se puede concluir que el uso de tareas de entrenamiento donde se lleven a cabo fases de ataque y defensa incrementa la carga externa, aproximándose más a las demandas de la competición.
