Comparative effects of unilateral and bilateral plyometric training on physical fitness in adolescent team-sport athletes: a systematic review and meta-analysis.

For sprint performance, the ≤10 m sprint included six studies with 164 participants; the effect favored unilateral PT, but the between-group difference did not reach statistical significance (SMD = −0.22, 95% CI −0.53 to 0.09, I2 = 0%, p = 0.164). ≥20 m sprint included eight studies with 240 participants, with no significant between-group difference (SMD = −0.06, 95% CI −0.31 to 0.20, I2 = 0%, p = 0.669).
