- ItemOpen AccessEl área de histéresis de las variables psicobiológicas. ¿Nuevo biomarcador no invasivo de la acumulación de esfuerzo?(Institut Nacional d’Educació Física de Catalunya (INEFC), 2023) Montull, Lluc; Abenza, Óscar; Hristovski, Robert; Balagué Serre, NatàliaEl área de histéresis, que refleja la dependencia de los parámetros psicobiológicos respecto a los antecedentes, se ha sugerido recientemente como nuevo marcador no invasivo del estrés y la tolerancia en relación con el ejercicio. Sin embargo, aún no se han explorado adecuadamente sus prometedoras aplicaciones. El objetivo de este estudio es comprobar si el área de histéresis del esfuerzo percibido (TEP), la frecuencia cardiaca (FC) y la concentración de oxihemoglobina muscular (O2Hb muscular) son sensibles a la acumulación de esfuerzo a lo largo de series múltiples de ejercicio de carrera. Diez estudiantes de Educación Física realizaron cinco series consecutivas de carrera a velocidad aeróbica máxima. Las series consecutivas comenzaban cuando los participantes comunicaban al menos una TEP ≤ 11 (escala de 6 a 20 de Borg). Se calcularon las áreas de histéresis de la TEP, la FC y la O2Hb muscular para cada serie y se comparó su magnitud utilizando la prueba ANOVA de Friedman y la prueba de Wilcoxon. Los tamaños del efecto se calcularon mediante la d de Cohen. Las áreas de histéresis de todas las variables estudiadas cambiaron entre las series iniciales y finales: la TEP y la FC aumentaron (entre las series 1-4): Z = –1.99, p = .04; Z = –2.19, p = .03, respectivamente), y la O2Hb muscular disminuyó (entre las series 1-4: Z = –2.80, p < .01). Se observaron efectos de gran tamaño (d = 1.22 - 1.81) en la FC entre las series 1-4, 1-5, 2-4, 2-5, y en la O2Hb muscular entre las series 1-4 y 1-5. Los resultados mostraron que las áreas de histéresis de la TEP, la FC y la O2Hb muscular eran sensibles a la acumulación de esfuerzo durante ejercicios repetidos de carrera realizados a velocidad aeróbica máxima. Si bien es necesario seguir investigando, el área de histéresis de las variables psicobiológicas apunta a ser un biomarcador sensible para la supervisión de la fatiga aguda.
- ItemOpen AccessHighlighting Shooting Opportunities in Football(MDPI, 2023) Loutfi , Ilias; Gómez Jordana, Luis Ignacio; Ric Diez, Ángel; Milho, João; Passos, PedroThe purpose of the present study was to create a two-dimensional model which illustrates a landscape of shooting opportunities at goal during a competitive football match. For that purpose, we analysed exemplar attacking subphases of each team when the ball was in the last 30 m of the field. The player’s positional data (x and y coordinates) and the ball were captured at 25 fps and processed to create heatmaps that illustrated the shooting opportunities that were available in the first and second half in different field areas. Moreover, the time that the shooting opportunities were available was estimated. Results show that in the observed match, most of the shooting opportunities lasted between 1 and 2 s, with only a few opportunities lasting more than 2 s. The shooting opportunities did not display a homogenous distribution over the field. The obtained heatmaps provide valuable and specific information about each team’s shooting opportunities, allowing the identification of the most vulnerable areas. Additionally, the amount, duration, and location of the shooting opportunities have shown significant differences between teams. This customizable model is sensitive to the features of shooting opportunities and can be used in real-time video analysis for individual and collective performance analysis.
- ItemOpen AccessSqueezing the most from volunteered geographic information to monitor mountain biking in peri-urban protected and recreational areas at a metropolitan scale(Elsevier, 2023) Nogueira Mendes, Ricardo Manuel; Farías Torbidoni, Estela Inés; Pereira da Silva, CarlosRecent studies have proved that volunteered geographic information is a valid data source to monitor outdoor activities within protected and recreational areas. However, these studies were carried out mainly at local scales, overlooking the real potential of such data for managing recreational activities on larger scales. In this research, using 9526 mountain bike tracks shared by 1319 identified riders, we studied 5 different peri-urban parks in a large metropolitan area. We learned that mountain biking actively targets these areas and that recreational behaviours shift according to each location. Users' commitment could be inferred from the dataset, adding new value to previous studies. This broader scale can also provide insights regarding riders’ preferences and behaviours, providing park staff and managers with better information ranging from use intensity in the entire area to identifying environmental and social conflicts, thereby allowing measures to be taken to mitigate these. Management implications •GPS tracks from volunteered geographic information (VGI) can provide park managers with information regarding recreational uses in their territories. •Uses and behaviours vary among local protected and recreational areas (P&RAs) regarding mountain biking in a metropolitan context. •These datasets can help managers of P&RAs to monitor mountain biking activity, its displacement and intensity. The datasets also help to identify suitable locations for implementing real counts, surveys, or awareness campaigns targeting this particular user group.
- ItemOpen AccessRoles, relationships, and motor aggressions: Keys to unveiling the emotions of a traditional sporting game(Frontiers Media, 2023) Lavega i Burgués, Pere; Alcaraz-Muñoz, Verónica; Mallén-Lacambra, Carlos; Pic, MiguelInternational organizations such as the UN and UNESCO set priority goals for education in the 21st century. This article shows the educational contribution of the Traditional Sporting Game (TSG) of Bear Guardian and Hunters that involves the three-chained roles. The three roles test players who share a unique social interaction ritual. This study was part of a training experience for university students in physical activity and sports sciences in the theory and practice of motor games subject at INEFC, University of Lleida (Spain). This research investigated the emotional intensity in these three roles, the emotional meaning units, and their correspondence with the emotional triad. This study is a mixed-methods research. After playing the game involved, 131 university students (46 women and 85 men) aged 18–35 years (M = 20.19, SD = 2.42) answered the validated GES-II scale indicating the intensity and causes of five basic emotions. The data were analyzed using different strategies (qualitative data: content analysis; quantitative data: descriptive statistical analysis, inferential and association rules). The methodology employed has revealed part of this game’s secret (intimate and subjective) code: the affectivity invisible to external observation. Among the findings, we highlight: (a) each role originates different intensities and units of emotional meaning; (b) the three roles feedback, need and complement each other in this socio-affective network of interdependent relationships; (c) the Bear is the central role of the game. The emotional meanings concerning the motor aggression of the Bear operate as a magnet that attracts four itineraries of association rules of meanings and emotional triads. In the hands of intelligent, prepared and sustainable teachers, this game can help students learn to live together and educate them to control and respectfully channel motor aggression. In this way, students will be active actors in the process of civilization in favor of sustainable development.
- ItemOpen AccessGame-Based Learning and Gamification in Physical Education: A Systematic Review(MDPI, 2023) Camacho Sánchez, Rubén; Manzano-León, Ana; Rodríguez-Ferrer, José Miguel; Serna, Jorge; Lavega i Burgués, PereThe use of educational games or some aspects of games in the educational context is known as game-based learning (GBL) or educational gamification. The objectives of this study are to assess the existing evidence about how GBL and gamification have affected the variables studied in each investigation over the past ten years; to analyse the educational levels, variables, dynamics, and types of games; and to determine the advantages of implementing these games in the classroom. A systematic review is proposed utilising the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology across five multidisciplinary databases by conducting an exhaustive search with inclusion and exclusion criteria, examining quantitative experimental studies exploring the use of gamification and GBL in physical education. The results identify GBL and gamification as significant learning methods due to their impact on student motivation, academic performance, and commitment to improving health and physical performance. Consequently, this study implies that more research is needed on the needs and challenges of students when they are learning through GBL or gamification.
