Introduction: Knee injuries are among the most common musculoskeletal conditions affecting soccer players throughout their careers. In particular, anterior cruciate ligament (ACL) injury is considered one of the most challenging injuries due to the invasive nature of its treatment and the prolonged rehabilitation process required for recovery.
Objetive: This study investigated the effect of attentional focus on the biomechanics of a single-leg jump in soccer players with a history of ACL reconstruction. Different attentional focus conditions were compared by assessing neuromuscular performance during the Drop Jump test using two-dimensional video analysis.
Mmethodology: An external attentional focus resulted in superior jump performance, as participants receiving external focus instructions achieved greater jump height and longer flight times compared with those receiving internal focus instructions.
Discussion: These findings support the constrained action hypothesis, suggesting that an external attentional focus promotes more efficient neuromuscular control and may facilitate improved performance in individuals undergoing rehabilitation following ACL reconstruction.
Conclusions: Instructions based on an external attentional focus appear to enhance movement efficiency and contribute to greater muscle force and power production in patients recovering from ACL reconstruction.
