- Data across all subjects are presented
- Hip-dorsal: the combination of “co-contraction at the hip” (RA + ES) and dorsal M-mode
- Hip-ventral: the combination of “co-contraction at the hip” (RA + ES) and ventral M-mode
- Ankle-dorsal: the combination of “co-contraction at the ankle” (TA + GL + GM + SOL) and dorsal M-mode
- Ankle-ventral: the combination of “co-contraction at the ankle” (TA + GL + GM + SOL) and “ventral M-mode
- Knee-dorsal: the combination of “co-contraction at the knee” (RF + VL + VM + BF + ST, GM + VL) and dorsal M-mode
- Singular: only one muscle loaded significantly on one of the first four PCs
- The muscles indicated in italics did not show up consistently in the co-contraction indicated. TA tibialis anterior, SOL soleus, GL lateral head of gastrocnemius, GM medial head of gastrocnemius, RF rectus femoris, VL vastus lateralis, VM vastus medialis, BF biceps femoris, ST semitendinosus, RA rectus abdominis, ES erector spinae
