Allometry of the leg muscles of mammals



Measurements have been made of the leg muscles of mammals ranging from shrews Sorex to an elephant Loxodonta. Allometric equations based on body mass have been calculated for muscle masses, fibre lengths and moment arms and the thickness of a tendon, in several groups of mammals. Departures from geometric similarity in mammals in general (excluding bipedal hoppers) are noted and discussed. Differences between primates; fissipedes, bovids and bipedal hoppers are also demonstrated.
