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.
