Fig. 3. (A) Representative strain record showing principal tensile (black) and compressive (grey) strains from the caudal surface of the radius during one trial lasting about 30 s. Strains are shown during the contact phase of identified loading cycles (swing phase and non-analyzed footfalls have been discarded). (B) Expanded view of five footfalls, showing a range of natural locomotor behaviors. (C) Two-dimensional scatterplot depicting the loading pattern for this surface (caudal radius, black diamonds), as well as the opposite surface (cranial radius, white diamonds; strain trace not shown), during this representative trial. (D) Principal tensile (black) and compressive (grey) strains for cranial, caudal and medial surfaces (medial surfaces show axial strains) for the metacarpus and radius during representative treadmill footfalls. Each panel shows three consecutive walks, trots and gallops from one goat during different trials. Note the difference in y axis scale for each surface.
