    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

    Portuguese adults’ concerns on the return to indoor sports practice after confinement due to COVID-19 pandemic -mitigation strategies proposals
    (Universidad de Murcia. Servicio de publicaciones, 2021) Matos, Rui; Amaro, Nuno; Antunes, Raul; Rosa, Marlene
    Objective: This study aimed to get an insight of Portuguese adult people concerns about returning to physical activity and sports practice at indoor sports facilities, after confinement due to COVID-19’ pandemic. Subsequently, an additional approach to the traditional mitigation strategies was to be proposed. Methods: A total of 173 Portuguese practitioners on indoor physical activity or sports before pandemic participated in this study. A questionnaire asking how much concerned (1 –nothing, to 5 –completely) would they be on different contexts and aspects related to this return was applied. Results: respondents were considerably concerned about this theme, especially with touching on common surfaces and proximity to others. Although considerable concerned if having to travel by public transport to the training facility, using locker rooms and with features of the sports’ practice itself, the former received the highest concerns. Additionally, we have suggested modifying some objects (or creating others) that may allow their use with body parts other than hands -an important contagion source -and exploiting the possibility of using intermediate instruments on objects and sports equipment manipulation, preventing users from touching their surfaces directly. Conclusion: touching on common surfaces and proximity to others revealed high degrees of concern on the return to indoor sports practice after confinement due to COVID-19 pandemic. Alongside the rules of personal distancing, respiratory etiquette and surfaces hygiene, it is suggested that sports practitioners, whenever possible, use alternative body parts and intermediate instruments that avoid direct contact of hands with surfaces and sport objects.
