Abstract

Performance in football results from a combination of factors, such as the physical characteristics of players, psychological skills, technical and tactical skills, most of which are trainable. The objective was to investigate the effect of a training season on the multidimensional indicators of the sporting potential of young footballers. 18 male soccer players from the under-14, under-15, under-16 and under-17 categories participated in the study (average: age 14.4 ± 1.3 years; weight 59.2 ± 9.0 kg; height 170.5 ± 9, 3 cm), who trained 3 to 5 times a week at a Brazilian training center for young footballers. The athletes were submitted to a battery of tests, before and after a training season, being evaluated anthropometric, physical-motor, psychological, technical and tactical skills, socio-environmental indicators, in addition to the coaches' subjective perception regarding the athletes' sporting potential. After a season of 11 months, a significant increase in anthropometric indicators (height, body mass and wingspan) and a reduction in fat percentage were observed. In addition, players had significant improvement in handgrip strength, flexibility, countermovement jumping power, agility, 20- meter speed, coping skills, dribbling and tactical skills. It is concluded that a training season promotes significant improvements in the multidimensional indicators of the sporting potential of young footballers.
