    Entrenamiento de fuerza en futbolistas jóvenes: hacia una óptima relación entre la magnitud de la carga y la mejora del rendimiento
    (Universidad de Murcia. Servicio de publicaciones, 2022) Magallanes, Adrián; Parodi, Andrés; Magallanes, Carlos; Gonzalez Ramírez, Andrés
    In soccer, sprinting speed and vertical jump are critical skills to achieve high performance. Controversy exists about which type of training is most appropriate to improve these skills in youth players with no previous experience in programmed strength training. The aim of this study was to evaluate the efficacy and efficiency of a 16-week programme of resistance (weight) and plyometric training on sprinting and vertical and horizontal jumping in male youth soccer players. The study involved 18 soccer players, 14.1 ± 0.3 years old, with no previous experience in programmed strength training. They performed a combined cycle of resistance and plyometric training on different days, twice a week, respectively. Before and after the experimental intervention, the athletes were tested in countermovement vertical jump, bipodal horizontal jump, unipodal horizontal jump and 30 m linear sprint. After the intervention, significant improvements were observed in all the variables analyzed (p ≤ 0.05). Given that the relationship between the improvement in performance and the magnitude of the loads applied was shown to be superior to other similar interventions, it is possible to conclude that this type of training programme is both effective and efficient in the population studied.

    The effects of plyometric and resistance training on linear sprinting speed and repeated sprinting ability of youth players in Ethiopia
    (Universidad de Murcia. Servicio de Publicaciones, 2025) Chekle, Belayneh; Sin departamento asociado
    The study investigated the effects of resistance training, plyometric training, and resistance and plyometric training combined on linear-speed and repeated sprinting ability (RSA) of youth soccer players. The authors used a randomized block design, randomly assigning thirty-six male soccer players (aged 18 ± 1.212 years, with a body weight of 57 ± 3.580 kg) to one of three groups: plyometric exercise, combined plyometric and resistance exercise, and resistance exercise. The authors analyzed each group's performance gains by comparing the pretest and post-test performance scores using paired sample t-test. All three training groups achieved significant performance gains in linear speed and repeated sprinting ability (RSA) (p<0.05). The plyometric and combined groups achieved higher linear-speed performance than the resistance training group (p<0.05). However, there was no significant difference among the three groups in repeated-sprinting-ability scores (p>0.05). In conclusion, plyometric and combined exercises are important training methods to impact speed for soccer players. Thus, when the focus is on soccer-specific linear speed and repeated sprinting ability, coaches and their training programs should emphasize methods that incorporate appropriate plyometrics and resistance training. This fitness-oriented training has to be considered in line with the technical and tactical trainings as they are helpful to get the most from the players’ technical-tactical qualities.
