    Desequilibrio de los jugadores y las jugadoras centrales en balonmano: Análisis de coordenadas polares y estimación de funciones
    (Universidad de Murcia. Servicio de publicaciones, 2025) Ortolani, Joaquina; Quiñones Rodríguez, Yarisel; Pastrana Brincones, José Luís; Hernández Mendo, Antonio; Morales Sánchez, Verónica; Sin departamento asociado
    The objective of this study was to examine the imbalance generated by central players in positional play in indoor handball, in the junior women's and men's national teams of Argentina, using polar coordinate analysis and validating non-observed data through function estimation. An observational tool composed of 12 criteria and 62 categories, previously validated for the study of positional play in handball, was employed. Six international matches were observed, with 149 multi-events coded in the women's category and 121 in the men's category. The effect size of the sample was calculated, yielding a significant result of 0.74. Subsequently, a polar coordinate analysis was performed to identify statistically significant relationships (Z ≥ 1.96) between the categories of the taxonomic system. Additionally, a function estimation analysis was conducted as a model for validating and predicting non-observed data. The results revealed notable differences between categories: in the women's team, central players' imbalance was associated with harassment actions and transformation of the offensive system, while in the men's team, it was linked to technical faults and subsequent tactical deactivation. These findings allow for the proposal of differentiated psychological intervention strategies for each team, aimed at optimizing sports performance by strengthening variables such as self-efficacy, self-confidence, decision-making, and emotional regulation. This comprehensive approach, integrating technical-tactical and psychological aspects, provides a solid foundation for designing training strategies adapted to the high-performance competitive context

    Mejora de la dureza mental en halteristas universitarios mediante una intervención con biorretroalimentación basada en el modelo IZOF
    (Universidad de Murcia. Servicio de publicaciones, 2023) Fernández Barradas, Erick Yael; Juvera Portilla, José Luis; Rodenas Cuenca, Luis Tomas; Hernández Cruz, Germán; Reynoso Sánchez, Luis Felipe
    La intervención psicológica en el contexto del deporte ha intentado detectar un modelo que pueda predecir el máximo rendimiento deportivo; los estudios en donde se utilizan programas de intervención psicológica en las fases competitivas han mostrado cierta influencia en la mejora de habilidades psicológicas específicas para la práctica deportiva. El presente estudio tuvo como objetivo evaluar el efecto de un programa de control de activación basado enla Zona Individual de Funcionamiento Óptimo (IZOF), sobre los niveles de dureza mental en deportistas universitarios de halterofilia. La muestra constó de tres participantes, seleccionados por conveniencia. Se utilizó un diseño preexperimental de pretest-postest con un grupo único. Se aplicaron el Inventario Psicológico de Ejecución Deportiva y el Inventario de Ansiedad Estado Competitiva-2RD, este último de manera retrospectiva considerando tres momentos deportivos: a) Peor Rendimiento; b)Rendimiento Regular; c) Mejor Rendimiento; y uno de forma prospectiva, d) Post-intervención. Se registro la frecuencia cardiaca como herramienta para determinar la IZOF. El programa de intervención constó de 17 sesiones para la enseñanza y aplicación técnicas de control de activación. Se analizaron las variables psicológicas mediante la prueba T de Wilcoxon y el mínimo cambio apreciable, mientras que se obtuvieron medias para la frecuencia cardiaca para evaluar su comportamiento durante las ejecuciones de rendimiento. Losresultados posteriores a la intervención muestran cambios positivos en los niveles de ansiedad y autoconfianza, así como de las habilidades psicológicas para la práctica deportiva, y, la obtención y mantenimiento de la IZOF en los participantes.
