Metabolics of Augmented Running

This paper details the on-going research to analyze and simulate the metabolic effects of running with mechanical assistance. A subject was augmented with bungee cords and ran on a treadmill; the subjectn’s O2 and CO2 were monitored. The subject was fitted with markers and motion was captured with an IR camera system. Ground reaction forces measured by the instrumented treadmill were recorded. From pilot VO2 / CO2 data, the group found that O2 consumption is significantly reduced with augmentation, as predicted. The effect is like running downhill. The team is currently learning to simulate the body and the effect of external forces using the OpenSim program. Immediate future work is to incorporate the bungee forces in an OpenSim simulation to predict metabolic rate. Involvement in research has had multiple educational benefits for the students. They have understood haw classroom theory applies in the laboratory. They have developed a sense of the complexity of research work.
