Sex differences in lower extremity biomechanics during single leg landings

摘要: Background. Females have an increased incident rate of anterior cruciate ligament tears compared to males. Biomechanical strategies decelerate the body in vertical direction been implicated as a contributing cause. This study determined if females would exhibit single leg landing characterized by decreased amounts hip, knee, and ankle flexion resulting greater ground reaction forces altered energy absorption patterns when Methods. Recreationally active males (N = 14) 14), completed five landings from 0.3 m height onto force platform while three-dimensional kinematics kinetics were simultaneously collected. Findings. Compared males, exhibited (1) less total hip knee displacements (40% 64% respectively, P < 0.05) time peak (48% 78% 0.05), (2) 9% (P (3) lower (76% (4) 11% relative at 0.05).
