在着陆和切割过程中，女性在膝关节处表现出更大的额状面力矩（内膝内收肌力矩或外膝外展肌力矩），并且与男性相比，女性更喜欢使用膝伸肌而不是髋伸肌来减弱冲击力。然而，尚不清楚这种生物力学特征何时出现。本研究的目的是比较不同成熟水平的性别之间的着陆生物力学。119名男女足球运动员（9-22岁）参加了比赛。受试者根据成熟发育进行分组。下肢运动学和动力学过程中获得的下降土地的任务。因变量包括平均膝内收肌力矩和矢状面膝/髋力矩以及着陆减速阶段的能量吸收比。当平均跨成熟水平，女性表现出更大的内部膝内收肌力矩（0.06±0.03 vs. 0.01±0.02 Nm/kg*m; P<0.005），膝/髋伸肌力矩比（2.0±0.1对比1.4±0.1 Nm/kg*m; P<0.001）和膝关节/髋关节能量吸收比（2.9±0.1对比1.96±0.1 Nm/kg*m; P<0.001）。在女性中观察到较高的膝内收肌力矩以及膝伸肌相对于髋伸肌的不成比例使用，反映了增加ACL负荷的生物力学模式。这种生物力学策略已经在青春期前的女运动员中确立。
During landing and cutting, females exhibit greater frontal plane moments at the knee (internal knee adductor moments or external knee abduction moments) and favor use of the knee extensors over the hip extensors to attenuate impact forces when compared to males. However, it is not known when this biomechanical profile emerges. The purpose of this study was to compare landing biomechanics between sexes across maturation levels. One hundred and nineteen male and female soccer players (9–22 years) participated. Subjects were grouped based on maturational development. Lower extremity kinematics and kinetics were obtained during a drop-land task. Dependent variables included the average internal knee adductor moment and sagittal plane knee/hip moment and energy absorption ratios during the deceleration phase of landing. When averaged across maturation levels, females demonstrated greater internal knee adductor moments (0.06±0.03 vs. 0.01±0.02 Nm/kg*m; P<0.005), knee/hip extensor moment ratios (2.0±0.1 vs. 1.4±0.1 Nm/kg*m; P<0.001), and knee/hip energy absorption ratios (2.9±0.1 vs. 1.96±0.1 Nm/kg*m; P<0.001) compared to males. Higher knee adductor moments combined with disproportionate use of knee extensors relative to hip extensors observed in females reflects a biomechanical pattern that increases ACL loading. This biomechanical strategy already was established in pre-pubertal female athletes.
