The aims of this study were to test the effects of two pressure relief insoles developed for backpackers and obese people on the ground reaction forces (GRF) and plantar pressure peaks during gait; and to compare the GRF and plantar pressures among normal-weight, backpackers, and obese participants. Based on GRF, plantar pressures, and finite element analysis two insoles were manufactured: flat cork-based insole with (i) corkgel in the rearfoot and forefoot (SLS1) and with (ii) poron foam in the great toe and lateral forefoot (SLS2). Gait data were recorded from 21 normal-weight/backpackers and 10 obese participants. The SLS1 did not influence the GRF, but it relieved the pressure peaks for both backpackers and obese participants. In SLS2 the load acceptance GRF peak was lower; however, it did not reduce the plantar pressure peaks. The GRF and plantar pressure gait pattern were different among the normal-weight, backpackers and obese participants.
本研究旨在测试两种为背包客和肥胖者设计的减压鞋垫在步态中对地面反作用力（GRF）和足底压力峰值的影响，并比较正常体重、背包客和肥胖参与者的 GRF 和足底压力。基于 GRF、足底压力和有限元分析，制造了两种鞋垫：带有（i）后跟和前脚掌 corkgel 的平底软木鞋垫（SLS1）和带有（ii）大脚趾和外侧前脚掌 poron 泡沫的平底软木鞋垫（SLS2）。从 21 名正常体重/背包客和 10 名肥胖参与者中记录了步态数据。SLS1 并未影响 GRF，但减轻了背包客和肥胖参与者的压力峰值。在 SLS2 中，负荷接受 GRF 峰值较低；然而，它并没有降低足底压力峰值。正常体重、背包客和肥胖参与者的 GRF 和足底压力步态模式不同。
