Fig. 13. Results (factor scores) from principal components analyses (PCA) using eight variables related to muscle function for the pMG during walking (black circles) and running (grey triangles), and for the dMG during walking (red circles) and running (pink triangles). (A) PC1 versus PC2. (B) PC1 versus PC3. Note that PC1 separated the two regions of the muscles, and PC3 separated the two speeds. See Table 4 for component loadings.
