Fig. 4.

Epimuscular force transmission with normal and enhanced connective tissues. Distribution of epimuscularly transmitted force among intermuscular connective tissues (INT) and extramuscular neurovascular tracts (NV1, NV2), over each step of $\text{SO}/\text{LG}+\text{PL}$ MTUs displacement ($\mathrm{\Delta }{P}_R$). Force values are expressed as a percentage relative to the $\text{LG}+\text{PL}$ proximal tendon total force ($\widehat{F}/F_{\mathrm{prox}}^{\mathrm{LG}}$ [%]) for the normal group (a) and the tissue-integration group (b). As an example, the distribution of force among the different pathways in respect to the myotendinous one, i.e., the proximal $\text{LG}+\text{PL}$ tendon, is shown for $P_R=2\text{mm}$
