- PublicationOpen AccessComparación de los ritmos de juego en Liga Femenina y ACB(Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2016) Romarís Durán, Iria Uxía; Refoyo, Ignacio; Lorenzo, J.En esta investigación se pretende comparar el ritmo de juego en baloncesto masculino y femenino analizando el número de posesiones que se realizan por partido, su duración y la influencia del uso de distintos tipos de ataque. Aplicando la metodología observacional se estudiaron las posesiones de 14 partidos de Liga ACB y 12 de Liga Femenina (LF) de la temporada 2009/10. Los análisis realizados ponen en evidencia que el ritmo de juego es un factor que distingue el baloncesto masculino y femenino, puesto que se encontraron diferencias estadísticamente significativas entre las dos categorías en todas las variables analizadas. Los resultados muestran que el ritmo de juego en LF es mayor que en ACB por tener un número medio de posesiones por partido superior (ACB 172 - LF 180,58) y porque la duración media de las mismas es menor (ACB 12,73 seg. - LF 11,82 seg.). Además en LF se juega a un ritmo más elevado que en Liga ACB debido al mayor uso de contraataques (ACB 10% - LF 12,8% del total de posesiones) y transiciones (ACB 3,9% - LF 5,2%) y la menor duración de los ataques posicionales (ACB 14,11 seg. - LF 13,2 seg.).
- PublicationOpen AccessComparing accuracy between global positioningsy stems and ultra-wideband-based position tracking systems used for tactical analyses in soccer(Willey, 2025-01-21) Bastida-Castillo, Alejandro; Gómez-Carmona, Carlos D.; Cruz Sánchez, Ernesto de la; Pino Ortega, José; Actividad Física y DeporteCurrent studies have reported high accuracy in global positioning system (GPS) and recently developed ultra-wideband (UWB)-based tracking systems for monitoring time – motion patterns. The accuracy and reliability of both systems may be different in tactical analysis application, an aspect that has never been studied previously. The aims of the present study were: (i) to determine and compare the accuracy of GPS and UWB technologies in soccer players’ positions (ii) to compare the tactical application of both systems. Following institutional ethical approval and familiarisation, 14 welltrained soccer players performed tests around five courses: (a) field perimeter, (b) halfway line, (c) centre circle, (d) perimeter of the penalty area, and (e) semicircle penalty area. Also, a small-sided game was played monitored with WIMUPRO™ to determine real and practical differences in accuracy of both systems in tactical analysis. For the GPS, the mean absolute error (N= 9445) of “x” and “y” coordinates was 41.23 ± 17.31 cm and 47.6 ± 8.97 cm, respectively. For UWB, it was 9.57 ± 2.66 cm and 7.15 ± 2.62 cm. The results of the “x” and “y” accuracy comparison were significantly lower in all cases (p < 0.05) with an ES of 0.78 and 0.95, respectively. In a real practical application, the differences of both systems reached 8.31% in typical tactical variables (ES = 0.11). In contrast to GPS-10Hz, UWB WIMUPRO™-20 Hz has been demonstrated to be an acceptable technology to estimate the position of players on the pitch with high accuracy and be a useful, automatic, and portable instrument for tactical analysis measurement.
- PublicationOpen AccessEffect of training day, match, and length of the microcycle on the worst-case scenarios in professional soccer players(Taylor and Francis Group Routledge, 2025-01-21) Oliva-Lozano, José M.; Gómez-Carmona, Carlos D.; Rojas-Valverde, Daniel; Fortes, Víctor; Pino Ortega, José; Actividad Física y DeporteThis study aimed to describe in-season worst-case scenarios (WCS) of professional soccer players and compare the WCS between training and match days (MD), considering the length of microcycle. A cohort study was designed for four competitive mesocycles in LaLiga123. The WCS of distance covered (DIS), high-speed running distance (HSRD), and sprinting distance (SPD) for four different WCS durations (1ʹ, 3ʹ, 5ʹ, 10ʹ) were analysed. Statistical differences between the WCS from training and MD were found at all intensities and periods. The magnitude of differences was moderate in DIS-1ʹ (F= 15.49; p< 0.01; ωp 2= 0.09) and DIS-3ʹ (F= 20.99; p< 0.01; ωp 2= 0.12), and high in the rest of variables (F= 26.53–89.41; p< 0.01; ωp 2= 0.15–0.38). Specifically, the WCS from MD reported the highest values at all intensities and periods. Regarding training days, the greatest WCS of DIS, HSRD, and SPD were found on MD-4, MD-3, and MD+1. Considering the length of microcycle, significant differences (p< 0.05) in training-days' WCS, but not in MD (p> 0.05). In conclusion, specific WCS training programmes (e.g., including 1 min to 10-min training drills in MD-4) may be useful to prepare the demands required on MD.
- PublicationOpen AccessPolar Coordinate Analysis to Study Counterattacks in Senior and Under-16 Men’s Handball(Murcia: Servicio de publicaciones de la Universidad de Murcia, 2020) Jiménez Salas, Jorge; Morillo Baro, Juan Pablo; Reigal Garrido, Rafael E.; Morales Sánchez, Verónica; Hernández-Mendo, AntonioThe aim of this study was to analyze counterattack actions by elite and under-16 players in men’s handballusing a methodologically validated taxonomic system. We analyzed counterattack actions in 17 games involving elite players as well as 10 games in Spanish championship of under-16 regional teams. We used the HOISAN software package and employed the polar coordinate analysis technique from the perspective of genuine retrospectivity. The taxonomy of the coding system was developed through a combination of a field format system and an exhaustive and mutually exclusive (E/ME) system of categories. The instrument includes 19 criteria and 148 categories. The focal categories used in this study were behaviors having to do with ball recovery, ball transport and counterattack completion. Differences between the studied populations were found for counterattack completion, deployment, transport and ball recovery. Technical errors were associated with the 6:0 defense in the elite categories and with the 5:1 defense in the under-16 category. In the senior categories, the number of players participating in counterattacks tended to be higher and a numerical advantage in the opponent’s half of the court was associated with the team being ahead in the score; in the under-16 category, this behavior was associated with trailing in the score. We also observed that greater defender and goalkeeper effectiveness gives rise to more counterattack situations and under more favorable circumstances, and that this effectiveness is a determining factor in the success of a counterattack. The polar coordinate technique has estimated the technical-tactical relations in competition, which will allow to determine the psychological intervention strategies that improve performance.
