摘 要：When humans jump down from a high position,there is a risk of serious injury to the lower ***,cats can jump down from the same heights without any injury because of their excellent ability to attenuate impact *** present study aims to investigate the macro/micro biomechanical features of paw pads and limb bones of cats,and the coordination control of joints during landing,providing insights into how cats protect themselves from landing ***,histological analysis,radiological analysis,finite element method,and mechanical testing were performed to investigate the mechanical properties,microstructure,and biomechanical response of the pads and limb *** addition,using a motion capture system,the kinematic/kinetic data during landing were analysed based on inverse *** results show that the pads and limb bones are major contributors to non-impact-injuries,and cats actively couple their joints to adjust the parameters of movement to dissipate the higher ***,the paw pads,limb bones,and coordinated joints complement each other and constitute a multi-level buffering mechanism,providing the cat with the sophisticated shock absorption *** biomechanical analysis can accordingly provide biological inspiration for new approaches to prevent human lower limb injuries.
