Demographics and outlier verification
We found no differences in height (F = 0.026, p = 0.974) and weight (F = 0.290, p = 0.753) among the three experimental groups. One participant from Exo-Sb had a step length symmetry index at EP over two standard deviations from the group mean. We considered this participant an outlier and removed him from the step-length SI analysis. There were no other outliers. We report Huynh-Feldt corrected p-values for models that did not pass Mauchly’s Test of Sphericity.
