Problem statement: The association between field-based tests has been predominately conducted in adult male football players. The importance of intermittent endurance performance, as meaningful physical fitness component for football players has been underlined. However, the physical demands imposed by the respective positional role may results on different capacity to perform intermittent exercise. Approach: Activity profiles and baseline intermittent endurance capacity were collected from twenty-nine elite sub-19 male Italian football players using global positioning system and yo-yo intermittent endurance test. Movement data were collected during four official matches. Purpose: to examine (i) whether playing position affect physical demands during a football game and (ii) whether these demands reflect the capacity to perform intermittent endurance exercise, in sub-19 elite male football players. Results: For all match-related parameters, physical performance was higher for defenders and midfielders compared to attackers. (P<0.05). Moreover, the capacity of performing intermittent endurance exercise was greater for defenders compared to other positional roles (P<0.05). Small to large correlations (P< 0.05; r= 0.24 to 0.65) were observed for defenders and midfielders. Conclusion: Physical demands during a youth football game differ per playing position and correlate with the capacity to perform intermittent endurance exercise. Coaches and anyone involved in training prescription for football player should account for these positional variations in distance covered in order to design position-specific physical drills. Key words: Yo-yo test; Testing; Time motion analysis; Global positioning systems; Acceleration.
