Soccer study: One-Legged or Two-Legged strength training – which boosts performance more?

This study looked at how adding one-legged or two-legged isometric (static) strength exercises to an 8-week training program affects jump height, sprint speed, and leg strength in 41 elite male youth soccer players aged 15-19. Players were split into three groups: one-legged training, two-legged training, or a control group with no extra isometric work. The goal was to see which type of training improves performance and reduces strength differences between legs.
