abstract="This study compared the biomechanics of jump landing tasks used in ACL research. Twenty-seven female subjects performed a drop landing (DL), a drop landing with a vertical jump (DVJ), and a forward jump landing with a vertical jump (FVJ). We hypothesized that as one progressed from the drop landing through the forward-vertical jump that the kinematic and kinetic demands would increase, with progressively increasing knee and hip forces, moments, and angles on landing. Separate repeated-measures ANOVAs were performed. The FVJ had the highest peak anterior tibial shear force (p < 0.001), hip flexion angle (p < 0.001), knee flexion moment (p < 0.001), and knee valgus moment (p < 0.001). The DL had the smallest knee flexion angle (p = 0.001) and hip flexion angle (p < 0.001), while the DVJ had the lowest knee valgus moment (p < 0.001). These results indicate that seemingly minor variations between jump landing tasks may influence landing biomechanics. Caution should be used when comparing studies using different tasks.<p /> <p>Language: en</p>",
