    Las diferencias en la preparación deportiva entre los deportistas del PlaDAR y Club URBA
    (Universidad de Flores, 2011) Zabaloy, Carlos Santiago; Gómez, Valeria; Gómez Smyth, Leonardo
    En el presente trabajo de investigación hemos estudiado las diferencias en la preparación deportiva de los deportistas del PlaDAR y de Club URBA. Como objetivo principal hemos tenido que identificar las diferencias existentes y luego hemos intentado clasificar a estos deportistas de acuerdo al nivel de preparación deportiva.

    Effects of plyometric training performed on different surfaces and with different types of footwear on the neuromuscular performance of team-sport athletes : A systematic review
    (Termedia, 2025) Sanchez-Ottado, Gastón R.; Spyrou, Konstantinos; Pereira, Lucas A.; Alcaraz, Pedro E.; Zabaloy, Carlos Santiago; Loturco, Irineu; Freitas, Tomás T.
    This systematic review aimed to analyze the effects of plyometric training (PT) performed on different surfaces and with different types of footwear on the neuromuscular performance of team-sport athletes, and to properly delineate the role of these specific factors (i.e., surface type and footwear) on PT outcomes. A systematic search was conducted according to the preferred reporting items for systematic reviews and meta analyses guidelines using PubMed, Scopus, and Web of Science for articles published before May 2024. From the total of 2832 articles, 35 met the inclusion criteria for the systematic review. The results indicate that sand surfaces seem to be more effective than other surfaces in increasing neuromuscular performance. Specifically, studies that investigated the intervention process found significant improvements in performance metrics after plyometric sand training. In terms of acute effects, the results were diverse and inconclusive, with no clear pattern of evidence. Despite presenting lower improvements overall, rigid surfaces required a lower number of contacts compared to other types of surfaces to achieve similar performance gains. PT in water is also recommended to promote neuromuscular adaptations. Regarding footwear, minimalist and rigid options were found to lead to higher improvements in various neuromuscular performance variables, likely due to enhanced energy efficiency and stability during PT sessions. The included studies indicated that PT on sand is highly effective for improving neuromuscular adaptations. However, training on rigid surfaces is more time-efficient, while aquatic surfaces are also recommended. Additionally, minimalist or rigid footwear acutely improves various athletic performance variables. Overall, when designing a PT program, it is crucial to consider both the surface and footwear to maximize neuromuscular adaptations.

    A randomized controlled trial of unresisted vs. heavy resisted sprint training programs : Effects on strength, jump, unresisted and resisted sprint performance in youth rugby union players
    (Termedia, 2025) Zabaloy, Carlos Santiago; Healy, Robin; Pereira, Lucas A.; Tondelli, Eduardo; Tomaghelli, Luciano; Aparicio, Juan; Vega, Franco; Medrano, Joaquín; Giráldez, Julián; Comyns, Thomas; Freitas, Tomás T.; Loturco, Irineu
    This study aimed to compare: 1) the effects of a 4-week unresisted vs. resisted sprint training programs (UST and RST with 50% body mass, respectively) on both resisted and unresisted sprint performance; and 2) the effects of these sprint training schemes on various strength-power measures (i.e., one-repetition maximum [1RM] and the isometric squat test (ISqT), eccentric hamstring strength in the Nordic hamstring exercise [NHE], and vertical and horizontal jump distances). Thirty-five under-19 male academy rugby players participated in the study and were randomly assigned to one of the two training groups. Players’ unresisted and resisted (50% BM) 30-m sprint performance, squat 1RM, ISqT, NHE, and jump capabilities were tested on different occasions. Only UST produced a significant reduction in unresisted 30-m sprint time (p < 0.05), whereas both groups exhibited significant changes in resisted sprint times at 10 m and 30 m, as well as maximum velocity (p < 0.005; ES: large). Regarding strength measures, RST led to significant increases in ISqT peak force, horizontal jump distance, and NHE strength (p < 0.011; ES: large). Overall, no significant differences were detected between UST and RST in any of the primary or secondary measures after the intervention. Both training methods were equally effective in improving resisted sprint performance in youth male rugby players. Moreover, UST and RST could be effective options for maintaining or even improving various neuromuscular measures (e.g., dynamic-explosive, isometric, and eccentric strength) when lower limb resistance training is reduced during the competitive season due to the congested schedule.
