Purpose: To analyze and compare the effects of 4 different resisted sprint training (RST) modalities on youth soccer players’ performance after 8 weeks of training. Methods: Forty-eight youth soccer players were first randomly assigned to 4 groups and only then completed 8 weeks of RST: horizontal resisted sprint, vertical resisted sprint (VRS), combined resisted sprint, and unresisted sprint. Performance in horizontal and vertical jumps, sprint, and change of direction (COD) ability were assessed 1 week before and after the training intervention. Magnitude-based inference analysis was performed for calculating within-group pre–post differences. In addition, an analysis of covariance test was performed for between-group comparison, using the pretest values as covariates. After that, the analysis of covariance P values and the effect statistic were transformed to magnitude-based inference. Results: Within-group outcomes showed that all resisted training modalities experienced improvements in sprint (small to moderate) and COD (small to large) performance. Moreover, all groups, except unresisted sprint, enhanced the horizontal jump performance. However, only VRS improved on vertical jump. Between-group comparison outcomes revealed that only VRS improved the sprint time compared with horizontal resisted sprint (moderate) and COD performance compared with all groups (moderate to large). In addition, VRS enhanced the countermovement jump performance (small to large) compared with the other groups. Conclusions: Independent of the orientation of the resistance applied, RST is an effective training method for improving sprinting and COD performance. Nevertheless, VRS may promote greater improvements on sprint and COD ability and have a positive additional effect on countermovement jump performance and the reduction of COD deficit.

El objetivo del presente estudio fue analizar la influencia del puesto específico desarrollado en el terreno de juego por jóvenes futbolistas en la capacidad de salto, sprint, agilidad y velocidad de golpeo. Participaron 36 jugadores de nivel sub-élite provenientes de las categorías inferiores (cadete y juvenil) de equipos de fútbol andaluces (edad: 15.87 ± 1,43 años; masa corporal: 65.38 ± 10,84 kg; altura: 1.71 ± .06 m). Se evaluó la composición corporal, el rendimiento en salto vertical (CMJ), la agilidad mediante el test de Balsom, velocidad de sprint en 5, 10, 20 y 30 metros, y la velocidad de golpeo con ambas piernas. Los análisis mostraron que existen diferencias entre delanteros y defensas en la velocidad en 20m (p = .012) y entre delanteros y mediocampistas en la velocidad en 30m (p = .008). En las demás variables no existen diferencias entre las distintas posiciones de juego. Se concluye que durante la etapa de formación del futbolista, en este caso adolescencia, el nivel de especialización de los mismos no es alto y, en consecuencia, su condición física no presenta unos rasgos marcados, específicos de una determinada posición en el campo, probablemente debido a que en estas edades y niveles, se persigue una formación integral del deportista y un desarrollo lo más amplio posible, tanto a nivel físico como técnico-táctico.Palabras clave.

The main objective of this paper was to analyze the influence of specific position in vertical jump ability, sprint, agility and kicking speed in young soccer players. 36 soccer players of sub-elite level from Andalusian youth soccer academies participated voluntarily in this study (age: 15.87 ± 1.43 years; body mass: 65.38 ± 10.84 kg; height: 1.71 ± .06 m). Body composition, vertical jump performance (CMJ), agility through Agility Balsom Test, sprint in 5, 10, 20 and 30 meters, and kicking speed with both legs, were performed. Analysis showed differences between forwards and defenders with respect to 20m speed test (p = .012), and between forwards and midfielders with respect to 30m speed test (p = .008). In other variables there were not significant differences according to the specific position. It is concluded that during the formation stage of a soccer placer, in this case, for adolescence, specialization level is not high, therefore differences were not found by specific position probably because in these ages and levels, the aims are a comprehensive training and physical and technical-tactical soccer player development.KeyWords.

(1) Background: An improved understanding of soccer players’ match-related physical performance and recovery may help conditioning programs and re-warm up strategies to increase team performance during official competitions. Therefore, the aim of this study was to analyze the acute effects of 45 min of official competition (first half in matches) on physical performance variables in U-16 youth soccer players. (2) Methods: 20 male soccer players (age: 14.4 ± 0.5 years; height: 1.70 ± 0.05 cm; body mass: 65.1 ± 11.6 kg) were recruited to participate in this study. Data was collected from five official matches. Participants performed the assessments in two stages of each match: after the pre-match warm-up and after the first half. Tests included rate of perceived exertion (RPE), 30-m sprint and countermovement (CMJ). (3) Results: Statistically significant differences were found (p < 0.001) when the measurements prior to the game were compared with those recorded after half time across all variables. Effect sizes (ES) were very large for RPE (ES = 1.82), moderate for 30-m sprint times (ES = 0.64) and small for CMJ (ES = −0.25). (4) Conclusions: After 45 min of official competition, our results suggest that U-16 soccer players demonstrated a reduction in sprint and jump performance, in addition to a higher RPE. Hence, this information could be useful when designing re-warming strategies that can be performed before the second half.
