These files are based on the data collected and analyzed by Sam Hamner (see https://simtk.org/home/runningsim and http://dx.doi.org/10.1016/j.jbiomech.2010.06.025). We provide you with experimental data from four two running cycles for each subject (08 and 19) at each speed (4 m/s and 5 m/s). Since your device will be evaluated based on its performance using the cycles you are provided as well as two cycles you are not provided, we suggest you use two cycles one cycle at each speed for designing ("training data") and reserve two cycles one cycle at each speed for confirming that your design will work in general ("testing data"). Please see the Getting Started with CMC Confluence page for more detailed descriptions of the files used by the CMC Tool.

Running CMC

To run CMC in the OpenSim GUI, load a the subject's -specific model for the gait cycle of interest in the GUI and launch the CMC toolTool. Next, load the corresponding CMC setup file, verify that all the file paths are correct, and click "Run". If you forget which model you have loaded, right-click on the model 's name in the GUI and select "Info" from the drop-down menu.

You can also run CMC from the command line as follows:

...

The provided model includes a "whole-body" metabolic probe, which reports the total metabolic cost of all muscles in the model (see the files included with CMC results ending in "_ProbeReporter_probes.sto").The probe reports instantaneous metabolic power, so you will need to integrate the resulting time series to determine the total amount of energy consumed during the simulation. Please see the Umberger2010MuscleMetabolicsProbe doxygen page for descriptions of the properties associated with the probe. (Note, in particular, the "report_total_metabolics_only" property.)

The Simulation-Based Design to Reduce Metabolic Cost example is a great resource in general if you're having trouble getting started.

On your mark, get set, go!
