本研究探讨使用原型下半身外骨骼（EXO）进行负载的代谢成本和步态生物力学的影响。9名美国陆军参与者以1.34 m/s的速度在0%的坡度上行走8分钟，携带20 kg，40 kg和55 kg的军事负荷，有和没有EXO。当佩戴EXO时，与对照条件相比，按体重和总质量缩放的平均耗氧量（VO 2）分别显著高出60%和41%。平均V
This study investigated the effects on metabolic cost and gait biomechanics of using a prototype lower-body exoskeleton (EXO) to carry loads. Nine US Army participants walked at 1.34m/s on a 0% grade for 8min carrying military loads of 20kg, 40kg and 55kg with and without the EXO. Mean oxygen consumption (VO2) scaled to body mass and scaled to total mass were significantly higher, by 60% and 41% respectively, when the EXO was worn, compared with the control condition. Mean V
