    La clasificación como variable diferenciadora de las características de la colocación en etapas de formación
    (Universidad de Murcia, 2018) González-Silva, Jara; Moreno Domínguez, Alberto; Fernández-Echeverría, Carmen; Claver Rabaz, Fernando; Moreno Arroyo, M. Perla
    El objetivo de la investigación fue conocer la asociación existente entre la clasificación del equipo en competición y variables de colocación, en ambos géneros y en etapas de formación. La muestra de estudio estuvo compuesta por 1638 colocaciones, realizadas por los 34 equipos (16 masculinos, 18 femeninos) participantes en el Campeonato de España cadete de Selecciones Autonómicas. Las variables de estudio fueron la clasificación y variables de colocación (zona de colocación, tipo de colocación, técnica de colocación, zona hacia donde se envía la colocación, tiempo de colocación). Los resultados mostraron asociación significativa entre la clasificación y zona de colocación, técnica de colocación y eficacia de colocación, en ambos géneros; entre clasificación y tipo de colocación, en género masculino; y entre clasificación y tiempo de colocación, en género femenino. Estos resultados ponen de manifiesto que, a pesar de que la colocación es una acción intermedia, tiene una importancia fundamental en el juego, pudiendo afectar a la clasificación final del equipo en competición.

    Shooting strategies and efectiveness after ofensive rebound and its impact on game result in Euroleague basketball teams
    (Murcia: Servicio de publicaciones de la Universidad de Murcia, 2017) Suárez Cadenas, Ernesto; Courel Ibáñez, Javier
    Ofensive rebound dominance has been widely shown as a key factor to success in basketball, since provide an extra attack. However, knowledge on how these second-options may results more efective is scarce. Tus, we aimed to discover the infuence of shooting after ofensive rebound on efectiveness, comparing diferences between winners and losers. Te sample consisted of 3010 shot attempts from Euroleague-Top-16. Variables pertaining to shooting efectiveness, shooting zone, and game result were registered through systematic observation. Statistical analyses included series of binomial logistic regression analyses. Results showed that shooting efectiveness increases by 67% when shooting after ofensive rebound (OR= 1.67; p< 0.01). Additionally, winning teams were more efective after ofensive rebound compared to losers (OR= 1.43; p= 0.03). Particularly, winners signifcantly scored more from the outside than defeated (OR= 3.40; p< 0.01), not fnding diferences in the inside (p= 0.62). In general, fndings point out important advantages of shooting after ofensive rebound, showing diferences between winners and losers tactics. Tus, it is suggested developing specifc tactical behaviours after ofensive rebound situations to increase scoring opportunities and winning chances.

    The mental fatigue impaired beach volleyball attack technical-tactical performance: a crossover and randomized study
    (Universidad de Murcia. Servicio de publicaciones, 2024) Costa, Yago; Domingos Gomes, Jarbas; Lima-Junior, Dalton de; Lanzoni, Ivan; Batista, Giklmário
    The aim of this study was to investigate the effect of mental fatigue on the technical-tactical performance of beach volleyball players. Twelve males young beach volleyball players (16.1 ± 0.9 years old)were recruited to participate in this crossover and randomized study. The simulated match was performed under two conditions (control: 30 min without performing cognitive activities; mental fatigue: 30 min performing Stroop Task). The match is recorded and technical-tactical performance was calculated (coefficient of performance and/or efficiency of serve, serve reception, set, attack, block, and dig actions). The mental fatigue was “moderate” after Stroop Task, and statistically significant compared to the control condition [Mental fatigue: 62.5mm ± 8.8 Vs. Control: 6.4mm ± 4.1; p=.0001; ES: 0.9 (moderate effect)]. Moreover, attack coefficient of performance and efficiency was lower in mental fatigue condition that control condition (CP: Mental Fatigue= 1.5 ± 0.4 Vs. Control= 2.3 ± 0.2, p= .001; Eff: Mental Fatigue= 23.7 ± 7.0 Vs. Control= 36.0 ± 9.5; p=.004). In conclusion, mental fatigue impaired attack performance of beach volleyball players (one of the main key to win in this sport). Thus, is recommended avoid cognitive tasks or high cognitive effort before training and matches.
