Ítem Analysis of speeds in the 400-meter hurdles and gender differences: A study from the Paris 2024 Olympics(Asociacion Espanola de Analisis del Rendimiento Deportivo, 0025-04) de Souza-Lima, Josivaldo; Giakoni-Ramírez, Frano; Muñoz-Strale, Catalina; Yáñez-Sepúlveda, Rodrigo; Duclos-Bastias, Daniel; Cortés-Roco, Guillermo; Bonilla, Diego A.; Olivares-Arancibia, Jorge; Valdivia-Moral, PedroBackground/objectives. This study aims to analyse the speed differences between men and women in the 400 meters during the Paris 2024 Olympic Games. Average speeds in each segment of the race were evaluated, highlighting gender variations and performance across the different rounds of the competition. Methods. A descriptive observational study was conducted using data from 208 athletes (50% women). Average speeds per 50-meter segments were analysed across all rounds (heats, semifinals, and final), applying Student's t-tests to compare results between genders. The significance level was set at p <.05. Results. The average speeds showed significant differences between sexes in all segments of the race (p <.05). The largest difference was observed in the first 150 meters, where men outpaced women by a margin of 0.97 km/h. By 250 meters, the difference decreased to 0.43 km/h. In the final rounds, the winners reached maximum speeds of 36.87 km/h (men) and 32.48 km/h (women). Conclusion. Men exhibit a biomechanical advantage in the race's early stages, while both sexes strategically adjust their pacing in the final rounds. These findings suggest that gender differences in performance are linked to both physiological and biomechanical fact ors. © 2025 ARD Asociación Española.Ítem Analysis of speeds in the 400-meter hurdles and gender differences: A study from the Paris 2024 Olympics(Asociacion Espanola de Analisis del Rendimiento Deportivo, 0025) de Souza-Lima, Josivaldo; Giakoni-Ramírez, Frano; Muñoz-Strale, Catalina; Yáñez-Sepúlveda, Rodrigo; Duclos-Bastias, Daniel; Cortés-Roco, Guillermo; Bonilla, Diego A.; Olivares-Arancibia, Jorge; Valdivia-Moral, PedroBackground/objectives.

Method: Quantitative and descriptive study based on data provided by the National Institute of Sports of Chile. The study analyzed funding requests, and the investment received by each sport and region, using descriptive statistical techniques to identify trends over time. Both traditional and emerging sports were included, and a comparative analysis between regions was conducted. Results: The Metropolitan Region was the primary recipient of funds, concentrating a significant portion of the total investment. Soccer led the requests with a total of 2,078 applications and over 12 billion USD in investment, followed by tennis with 1,518 applications and over 11 billion USD. A notable increase in investment was observed in 2023, linked to the preparation for the Pan American Games in Santiago and the 2024 Olympics. However, other emerging disciplines showed lower participation in funding requests. Conclusion: Sports investment in Chile has shown significant growth, particularly in popular sports and in the Metropolitan Region. However, there is a need for more equitable support for less traditional disciplines and regions with less access to resources, to promote more inclusive sports development across the countryÍtem Physical Activity in Immersive Virtual Reality: A Scoping Review(MDPI, 2023-06) Giakoni-Ramírez, Frano; Godoy-Cumillaf, Andrés; Espoz-Lazo, Sebastián; Duclos-Bastias, Daniel; del Val Martín, PabloPhysical activity has benefits for health, but many adolescents are inactive. However, video games such as Immersive Virtual Reality (IVR) have grown in popularity as a leisure activity among young people, allowing them to manipulate objects in virtual environments increasing the practice of physical activity. The evidence indicates that the interest in physical activity through IVR is greater than in traditional methods, and different experiences have been reported. However, few studies indicate the sample evaluated, the effects found, or the IVR instruments used. Due to this, is the aim of this study is to identify the publications referring to IVR and physical activity, characterize them, and present the obtained main findings. For this, the guidelines described in the PRISMA-ScR for scoping reviews were applied. After the use of the inclusion and exclusion criteria, eight articles were included. Results show evidence regarding physiological outcomes, perceptual variables, interest and enjoyment, and psychological effects regarding physical activity through IVR. Additionally, the use of different devices and their prescriptions are explored. It is concluded that there is interest from the scientific community for the practice of physical activity through IVR, as well as for its application for the maintenance of active habits. This is important as it positions IVR as a method that can be a more experiential and effective way to develop and maintain a healthy lifestyle. © 2023 by the authors.
