    Análisis de las interacciones de la línea de medios de un equipo de fútbol de élite. Estudio de caso
    (Universidad de Murcia. Servicio de publicaciones, 2023) Amatria Jiménez, Mario; Marqués Millán, Raúl; Ramírez San José, Javier
    El análisis de las interacciones que se producen entre jugadores de un equipo de fútbol durante una competición tiene una gran importancia ya que del resultado de las mismas se alcanzan los resultados de los encuentros. Unas interacciones que a priori parecen ser fruto de la casualidad, pero se ha demostrado que no son el resultado del azar. La capacidad de anticiparse y/o estar preparado a estos comportamientos del adversario, aumentará las posibilidades de éxito. Por ello se ha establecido un doble objetivo de estudio; identificar mediante análisis de coordenadas polares las relaciones y vínculos que se establecen entre los jugadores que componen la línea de medios, centrocampistas, del equipo campeón de la Supercopa de España 2020, el Real Madrid CF entre sí. Así como identificar las sinergias que se producen entre esta línea de jugadores, en su conjunto, con las diferentes líneas que conforman la estructura táctica del equipo.Para ello se ha hecho uso de un instrumento de observación contrastado para la recogida de datos los cuales se trataron, posteriormente, mediante el análisis de coordenadas polares. En ellos se constata que la línea de medios, en referencia a las relaciones inter-líneas, manifiesta una desconexión de la línea de medios con la defensa y portero, y se relaciona consigo misma de forma significativa, aunque no con la misma intensidad en todos sus miembros (relaciones intra-línea).

    Análisis observacional de las acciones con balón de los delanteros centro en la UEFA euro 2020
    (Universidad de Murcia : servicio de publicaciones, 2026) Fernández-Sante, Daniel; Iván-Baragaño, Iyán; Maneiro, Rubén; Ardá, Antonio; Sin departamento asociado
    The objectives of this study were to analyze the offensive ball actions performed by center forwards in UEFA EURO 2020, to understand the relationship among various analyzed technical–tactical criteria and categories -including spatial, interactional, and intentional criteria-and the result of the action, and to establish a predictive model of the action results. To do so, 599 UEFA EURO offensive forwards actions were analyzed using observational methodology by means of an ad hoc observation instrument composed of 4 dimensions, 14 criteria and 129 categories, with an inter-observer reliability of κ = 0.842. Three types of analysis were carried out: a descriptive analysis by counting absolute and relative frequencies, a bivariate analysis using contingency tables between the criteria included in the observation instrument and the action result, and finally a predictive model based on binary logistic regression. The results obtained showed that the criteria modifying the result of the forwards' actions were: Area where the ball comes from (χ²= 140.3; p< .001; ES=.342), Area where the action takes place(χ²= 148.7; p< .001; ES=.352), Initial interaction context(χ²= 57.7; p< .001; ES=.219), Previous action(χ²= 78.2; p< .001; ES=.256), First-contact surface(χ²= 20.5; p= .002; ES=.131), Field area where the ball goes(χ²= 498;p< .001; ES=.645), Tactical intention(χ²= 73.9; p< .001; ES=.351), Action performed(χ²= 557.9; p< .001; ES=.682), and Final interaction context(χ²= 348.2; p< .001; ES=.539). From the multivariate approach, the logistic regression model has shown a predictive capacity of 80% when it came to predicting the ability of center forwards to maintain ball possession. The significant predictor variables were the Initial interaction context, the Tactical intention and theAction performed. These results can be useful when preparing and training for the specific position of the center forward as well as increasing their performanc

    Caracterización de los saques de esquina en el Campeonato Brasileño de Fútbol
    (Universidad de Murcia: servicio de publicaciones, 2025) Silva,Eduardo Henrique Amancio; Clavijo, Fabian Alberto Romero; Reame, Giovani Augusto Galindo; Burkle, Bruno Feijo; Drews, Ricardo; Sin departamento asociado
    This study characterized the corner kicks performed in the Brazilian Football Championship games. 1450 corner kicks from 148 games of the Championship edition held in 2020 were analyzed, with all sampled games taken from the broadcast coverage of closed television channels. The observation instrument used was adapted from different studies that investigated corner kicks in international competitions. The data were analyzed descriptively, from absolute (N) and relative (%) values and through cluster analysis using the maximum distance method between Cita: Silva, E. H. A.,Clavijo, F. A. R.,Reame, G. A. G.,Burkle, B.F.&Drews, R.Characterization of corner kicks in the Brazilian Soccer Championship. Cuadernos de Psicología del Deporte,25(2), 245-263 grouping values, based on the gower method for mixed variables. In addition, a bivariate analysis was performed with contingency tables using a chi-square test for categorical criteria, with the criterion variable being the result of the corner kick (Goal x no Goal). The results indicated that, on average, 9.81 corner kicks were taken per match, most of which were directed to the penalty area, executed between the 60th and 75th minutes of the game, and delivered with a high trajectory and external arc, and finalized mainly with the head. On the other hand, only thirty-two corner kicks (2.58%) resulted in goal. Inferential analysis revealed that the final contact surface was related to the result of the corner kick (X2 = 16.878, p = 0.002, Cramer’s V = 0.12). It is concluded that the corner kicks in the Brazilian Soccer Championship share similar characteristics to those found in other countries, and these characteristics may be aimed at deceiving the opponent to score

    Comparación de las variables de rendimiento en las principales ligas europeas de hockey sobre patines
    (Universidad de Murcia. Servicio de Publicaciones, 2023) Trabal Tañà, Guillem; Peña, Javier; Moreno-Galcerán, Daniel; Merino, Jordi; Buscà, Bernat; Arboix Alió, Jordi
    El presente estudio tuvo como objetivo comparar las variables de rendimiento del hockey patines en los campeonatos nacionales de la máxima categoría masculina en España (OK Liga), Portugal (Primeira Divisao) e Italia (Serie A1). Se analizaron un total de 1.665 partidos disputados entre las temporadas 2018-2019 y 2020-2021, correspondientes a la OK Liga (654), Primeira Divisao (497) y la Serie A1 (514). Se realizaron comparaciones utilizando el análisis de varianza (ANOVA) con post hoc de Bonferroni y la prueba t-Student para comparar las variables según la localización del partido. Los resultados muestran que en España se marcan menos goles por partido, que en Italia se marcan más goles por partido y que en Portugal hay más ejecuciones y goles de penalti y de falta directa, mayor cantidad de faltas y de tarjetas y un mayor porcentaje de goles de pelota parada respecto a los goles totales. En los tres campeonatos las variables de rendimiento asociadas a la victoria fueron favorables a los equipos locales. La comparación de los campeonatos puede permitir a los entrenadores tener un mejor conocimiento de las variables de rendimiento de cada competición y ayudar a las federaciones a conocer que competiciones están mejor asociadas con las variables determinantes del espectáculo deportivo, especialmente los goles, para diseñar propuestas de mejoras en los campeonatos pertinentes

    Diferences between ofensive and defensive ratings of rookies and sophomores in the NBA basketball league
    (Murcia: Servicio de publicaciones de la Universidad de Murcia, 2017) Prieto Bermejo, Jaime
    Te purpose of this study was to analyse and compare the ofensive and defensive performance of rookies (frst-year players) and sophomores (second-year players) in the NBA basketball league, in order to ascertain whether a second year of experience in the league results in higher performances. We hypothesised to fnd overall higher ofensive and defensive performances in second-year players when compared to frst-year. Ofensive and defensive rating statistics for rookies and sophomores for seasons 2014/2015 and 2015/2016 were downloaded and fltered from the stats section of the NBA ofcial web portal for a total of 144 players under analysis. A multivariate analysis of covariance (MANCOVA) was computed. ‘Ofensive Rating’ and ‘Defensive Rating’ were used as dependent variables; ‘Level of Experience’ (rookie vs. sophomore) was used as independent variable. Te average number of minutes played by each player during the league was considered as a covariate. Contrary to what was hypothesised, although both ofensive and defensive ratings showed slightly higher values for second-year players when compared to frst-year players, the diferences were not statistically signifcant. Tese results suggest that one more year of experience in the league is not sufcient to signifcantly increase the performance of the players on their way from rookies to sophomores. Hence, the results might suggest that the road to excellence has begun to be travelled, with two seasons in the league still being insufcient to show signifcant diferences in the overall performance of these yet novice players.

    Evaluación de la coherencia estratégico-táctica entre la preparación y el rendimiento de un equipo femenino de baloncesto
    (Universidad de Murcia : servicio de publicaciones, 2026) Monteiro, Alan; Rangel, Wellington; Fellingham, Gilbert; Heiner, Matthew; Lamas, Leonardo; Sin departamento asociado
    Integrative assessment of a basketball team combining the preparation phase and match performance is key for preventing coaches from misleading interpretations about outcomes. The goal of the study was to evaluate the coherence between team preparation and match performance in a women basketball team supported by data and considering the emphasis and efficiency on tactical contents. Coherence was evaluated based on the emphasis given to pre-defined basketball contents, and respective efficiency, during practices and match. Data were gathered a women’s college team (15 players; 20.0 ± 2.5 years old), in preparation for the national tournament. Team strategy was assessed from the season’s playbook. Practice data was gathered from the full pre-season period. Competitive performance was analyzed from a match. Bayesian methods were used to compute the posterior distributions of the parameters for time of training tasks. Set offense was emphasized more than transition during both practice and match, although their match efficiencies were similar. Team plays were prioritized over group tactics throughout practices (posterior mean difference: 42.3 min/week, SD: 10.1, 90% CI [25.8–58.9]) and in match performance, demonstrating higher efficiency. Our approach successfully traced preparation–performance coherence in a basketball team. Practices reflected a game-based approach that emphasized offense–defense integration and set offense supported by team plays. Coherence was demonstrated by the higher proportion of set offenses relative to transitions, both during practices and match. Similarly, a greater proportion and efficiency of team plays compared with individual or group actions. The approach should provide objective coaching support

    Short-term effects of adding 1-m wide to each side of the basketball court on youth players’ performance
    (Murcia: Servicio de publicaciones de la Universidad de Murcia, 2020) Mateus, Nuno; Gonçalves, Bruno; Exel, Juliana; Esteves, Pedro; Sampaio, Jaime
    This study aimed to identify short-term effects on basketball players’ physical responses, technical performance, and tactical behaviour when the court dimension is increased 1-m wide to each side. Fourteen youth players participated in 5 vs. 5 simulated basketball games, under two different conditions: regular court (28x15m) and wider court (28x17m, 1-m wider for each side). Besides the assessment of physical and technical indicators, positional data were also used to compute the following variables: distance to the nearest opponent, distance to the nearest teammate, stretch-index and distance between centroids. Results indicated that in the wider court condition, the dispersion of player’s displacement trajectories duringthe offensive phase increased, which had slight repercussions on their physical responses and in the teams’ playing patterns. Conversely, during the defensive phase, players tended to move within the regular spatial references, regardless of court width manipulation. Overall, this study emphasizes that short-term effects of changing the court dimensions are relatively negligible, suggesting that informational constraints might require longer time-scales to yield robust changes in players’ performance.
