Towards Subject-Specific Strength Training Design through Predictive Use of Musculoskeletal Models

Figure 6

Progression of the M. gluteus medius (GM) muscle activations [0 → 1] with external force direction. The overall maximum activations of all force directions are shown for the anterior (solid line) and posterior (dashed line) part of the muscle as a function of the muscle length (m) for the flexion/extension (a) and abduction/adduction (b) movements, as well as for the different hip rotation configurations: neutral (black), externally rotated (red), and internally rotated (blue).
