Fig 2. Effect of body size and posture on limb EMA.

Fig 2

(A) Hindlimb EMA scaling for mammals (data reported in [17, 31]) shows that EMA scales with M0.26. (B) Effect of hindlimb posture on limb EMA (ratio of extensor muscle moment arm (r) to the resultant three-dimensional ground reaction force moment arm (R) shows that crouched animals have a lower limb EMA than upright animals. Dashed black arrows represent the ground reaction force vector.
