Figure 6. Change in architecture of the soleus with passive muscle lengthening.

Figure 6

(A) Fascicle length, (B) pennation angle and (C) curvature, grouped by muscle compartment. Values are parameter change per centimetre increase in muscle-tendon length. White squares and vertical bars indicate mean value ± 1 SD over all subjects. Thin dashed lines connect the measurements made on one subject. Horizontal bars indicate statistically significant differences between compartments (* p < 0.05, ** p < 0.01, *** p < 0.001). MA, medial-anterior; LA, lateral-anterior; MP, medial-posterior; LP, lateral-posterior.
