The aim of this study is to know the effect of a unilateral and bilateral strength training program has on sprint performance of young footballers. 56 subjects distributed into 3 groups: unilateral (GEU), bilateral (GEB) and control (GC) were evaluated in sprint (10 and 20 m) before (pre-test) and after (post-test) of a training period. GEB performed strength training with bilateral exercises, GEU with unilateral exercises and GC did not train. Results show that GEU improved sprint performance in 0-10m (p <0.05) and 0-20m (p <0.01) distances, while GEB only improved in 0-10m (P <0.05) and GC didn´t change. Therefore, the unilateral training program was effective to improve 10 and 20m sprint performance, while the bilateral training program was effective only to improve performance in 10m.
