本研究的目的是调查落地过程中下降高度对下肢关节和肌肉力量的影响。要求10名成年受试者从3个不同高度（32厘米、52厘米和72厘米）落地，测量地面反作用力和下肢运动学。然后，将实验数据输入AnyBody建模系统，该软件对每个受试者的肌肉骨骼系统进行建模。通过反向动力学分析来计算每次着陆试验的关节和肌肉力，并评估跌落着陆对结果的影响。计算模拟表明，随着下降高度的增加，所有髋、膝、踝关节的垂直力，以及股直肌、臀大肌、臀中肌、股大肌、股二头肌和大收肌的力均显着增加。下降高度的增加还导致髂腰肌、股直肌、臀中肌、臀小肌和比目鱼肌较早激活，但胫骨前肌较晚激活。定量的关节和肌肉力可作为有限元分析中的加载条件，计算下肢各组织的应力应变和能量吸收过程。
The objective of this study was to investigate the effect of dropping height on the forces of joints and muscles in lower extremities during landing. A total of 10 adult subjects were required to landing from three different heights (32 cm, 52 cm, and 72 cm), and the ground reaction force and kinematics of lower extremities were measured. Then, the experimental data were input into the AnyBody Modeling System, in which software the musculoskeletal system of each subject was modeled. The reverse dynamic analysis was done to calculate the joint and muscle forces for each landing trial, and the effect of dropping-landing on the results was evaluated. The computational simulation showed that, with increasing of dropping height, the vertical forces of all the hip, knee, and ankle joints, and the forces of rectus femoris, gluteus maximus, gluteus medius, vastii, biceps femoris and adductor magnus were all significantly increased. The increased dropping height also resulted in earlier activation of the iliopsoas, rectus femoris, gluteus medius, gluteus minimus, and soleus, but latter activation of the tibialis anterior. The quantitative joint and muscle forces can be used as loading conditions in finite element analysis to calculate stress and strain and energy absorption processes in various tissues of the lower limbs.
