Agility development in youth soccer: the efficacy of fixed-role small-sided games.

PURPOSE

This study aimed to evaluate the impact of Fixed-Role Small-Sided Games (FRSSGs) on youth soccer players' agility and its components: reaction time, linear speed, and change-of-direction speed (CODS).

METHODS

Thirty-one male U-12 regional soccer players were randomly assigned to the FRSSG group ( = 16; age: 10.63 ± 0.48 years) or the control group (CON) ( = 15; age: 10.89 ± 0.31 years). The intervention program lasted 18 weeks. Pre- and post-intervention tests assessed reaction time, linear sprint speed (10 m and 20 m), CODS (505 and zig-zag tests with/without the ball), and agility (Y-shaped with/without the ball and multiple-signal tests). Statistical analysis included paired -tests, repeated measures ANOVA, and effect sizes (Cohen's d).

RESULTS

Significant baseline differences were observed between groups in 10-meter linear speed, and zigzag test performance ( < .05). Within-group improvements were observed for the FRSSG group in the 505 Test (-6.85%,  < .001,  = 1.375), Zigzag Test (-10.77%,  < .001,  = 2.148), CODS Zigzag Ball Test (-9.42%,  < .001,  = 1.434), Y-shape Ball Test (-9.49%,  < 0.001,  = 2.195), and Agility Multi-signal Test (-8.42%,  = .002,  = 0.821). Significant between-group differences favoring FRSSG were found for the 505 Test ( = 0.005,  = 0.038), Zigzag Test ( < .001,  = 0.435), CODS Zigzag Ball Test ( = 0.004,  = 0.04), and Y-shape Ball Test ( = 0.006,  = 0.027).

CONCLUSION

FRSSGs have been shown to effectively enhance agility and change of direction speed, both with and without the ball, in youth soccer players.
