The study found that landing with a deeper knee flexion angle (LFL) leads to smaller impact forces, reducing the risk of non-contact ACL injury.
Anterior cruciate ligament (ACL) injury is one of the most common knee injuries that negatively affect athletes' future performance and return to play. The purpose of this study was to examine the correlation of kinematics and kinetics of changing sagittal plane body position during landing and the risk of non-contact ACL injury. Seven university female (age 19.57 +/- 0.79 y, height 164.21 +/- 8.11 m, weight 60.43 +/- 5.99 kg) athletes playing soccer and handball, and with >= two years of training volunteered for this research. Three trunk positions: Lean Forward Landing (LFL), Self-selected Landing (SSL), and Upright Landing (URL)-via double/single-leg landing-were captured by a high-speed VICON motion capture system. A 3 x 2 two-way within-subjects ANOVA and Multiple Bonferroni corrected pairwise were used to test for condition (LFL, SSL, URL) and task (single/double-leg) effects (p <= 0.05). The findings indicated that landing with a deeper knee flexion angle (LFL) would lead to smaller impact forces when compared to upright landing.
