Fig. 5. Semi log-transformed plot of relationship of fiber-length-to-muscle-length ratio (L_f/L_m ratio) and body mass in adductor longus (AddL), lateral head of gastrocnemius (GLH), soleus (SOL), flexor digitorum longus (FDL) and tibialis anterior (TA). The L_f/L_m ratio of all muscles scales negatively with increasing body mass, meaning that larger animals generate relatively smaller fiber excursions than smaller animals. This is especially true for the TA and SOL, both of which have larger scaling exponents than the other muscles.
