Figure 6

Lumbosacral (L5/S1) joint moments (normalized to body weight times height) during running at Froude number = 0.8. Thick lines are means of ensemble averages, with shaded region as the standard deviation. Thin lines are means of participant ensemble averages. IMU = inertial measurement units; OMC = optical motion capture; RMSE = root mean squared error; NRMSE = normalized root mean squared error; R = cross-correlation.
