Fig. 4. Cross-sectional longitudinal strain distributions in the radius from the same intermediate-sized goat during a gallop (3.57 m s^–1) as shown in Fig. 1. Five phases are shown as percentage of time through stance: (A) 0%, (B) 25%, (C) 50%, (D) 75% and (E) 100%. Anatomical axes are labeled in A. The position of the neutral axis is indicated by the heavy black line. The outline of the ulna is included for reference, located caudo-lateral to the radius. The scale for the color gradient goes from red for negative (compressive) strains to yellow near zero strain and toward green for positive (tensile) strains.
