Fig. 2. Mean peak principal bone strains from the (A) cranial and (B) caudal surfaces, and (C) mean peak axial strains from the medial surface recorded at the midshaft of the radius for the small, intermediate and adult groups at a walk, trot and gallop. Error bars represent ±1 S.D. Medial axial strains are not present for the adult group, as they were not collected in Biewener and Taylor (1986).
