    Efectos del entrenamiento en la habilidad para repetir sprints (RSA) en arbitros de baloncesto
    (Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2015) Bayón, P.; Vaquera, A.; García-Tormo, J.V.; Dehesa, R.
    La mayor parte de los estudios en baloncesto se han centrado en el estudio de los jugadores existiendo pocos que se hayan centrado en el estudio de los árbitros de baloncesto. La habilidad para repetir sprints (RSA) es uno de los componentes claves en el rendimiento físico en baloncesto. Por ello, el objetivo de este estudio es analizar la RSA y los valores cineantropométricos en árbitros de baloncesto después de un periodo de entrenamiento de 5 semanas. 24 árbitros fueron analizados, divididos en Grupo Control (GC) y Grupo Experimental (GE). Se les realizó una determinación cineantropométrica (Talla, Peso, % Graso y IMC) y un test de RSA de 7x20 m. en dos ocasiones, antes y después de estas semanas de entrenamiento (PRE y POST). Encontramos pequeñas diferencias en el peso en ambos grupos entre el PRE y POST así como diferencias en el % graso, donde ambos disminuyeron, 2.5% el GC y 5.29% el GE. Las mejoras en el RSA fueron evidentes, siendo 0.67% para el GC y 5.10% para el GE. En conclusión, después de un entrenamiento específico, las mejoras en RSA en árbitros de baloncesto claramente mejorarán su condición física así como sus valores cineantropométricos.

    Effects of a 10-week dry-land strength and conditioning program in physical capacities and start of previouslyfederated and regular swimming practitioners
    (Universidad de Murcia. Servicio de publicaciones, 2022) Silva, Carlos; Jesus, João; Vilarigues, Iuri; Aranha, Ivo; Candeias, Iuri; Santos, Fernando; Figueiredo, Teresa; Espada, Mário
    The aim of this study was to evaluate the effects of a 10-week strength and conditioning (S&C)program in physical capacities and start in previously federated and regular swimming practitioners. 16 swimmers (9 male, 17.00±2.16 years of age, 179.14±5.76 cm of height and 69.79±3.11 kg of weight; 7 female, 15.86±2.34 years of age, 163.86±4.98 cm of height and 60.19±3.60 kg of weigh) were equality, but randomly separated in two groups (control group and experimental group, CG and EG, respectively). In the pre-test, swimmers performed three starts in two different models, grab start and track start, the best start was registered. Kinematic parameters of the swimming start and time at 15 m were determined. Flexibility, countermovement jump and 3 kg medicine ball throw were also assessed. In post-test, 10-weeks after a regular 2-sessions week specific dry-land S&C program of 60 min was performed by the EG, all tests were repeated. Flexibility, strength and muscular power gains were significant in EG, contrarily to CG. Swimming start flight phase variables improved more in EG compared to CG, with specificities observed in grab and track start but not a linear consequence with performance in 15-m mark in both groups. A 10-week dry-land S&C program can provide benefits in physical capacities in regular swimming practitioners, fact that may improve the initial phase of the swimming start, prior to the underwater moment, which should deserve attention by the coaches in daily training aiming performance enhancement at 15 m.

    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
