Simulating Ideal Assistive Devices to Reduce the Metabolic Cost of Running

We used simulation to predict and gain insight into the biomechanical and energetic effects of assisted running, and to demonstrate the potential for simulation to complement experimental approaches to device design. We performed muscle-driven simulations of running at 2 and 5 m/s, then added ideal, massless assistive devices and examined the predicted changes in muscle recruitment patterns and metabolic power consumption. We predicted the optimal assistive device torque profiles and sought explanations for the observed changes in muscle activity. By ignoring device mass and other practical factors, we avoided confounding the beneficial effects of adding assistance with the detrimental side effects often encountered experimentally. <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=1067#pack_1874">Supporting data </a> : Please unzip and see README.md for details. </li> </ul>

本研究采用仿真技术预测并洞察了辅助跑步的生物力学和能量效应，同时展示了仿真方法在补充设备设计实验方法方面的潜力。我们对以肌肉驱动的跑步进行仿真，速度分别为2米/秒和5米/秒，随后添加理想的、无质量的辅助装置，并研究了预测中肌肉募集模式和代谢功率消耗的变化。我们预测了最佳辅助装置扭矩曲线，并寻求对观察到的肌肉活动变化进行解释。通过忽略设备质量及其他实际因素，我们避免了将辅助带来的益处与实验中常见的有害副作用混淆。
