Compressions in the forelimb of a horse trotting at 3.7 m/s were studied using high-speed cinematography. From a diagram of shortenings it has been concluded that successive loadings in the longitudinal direction from below signify longer impact time and smaller impact forces compared to a theoretically stiff limb. It is proposed that the limb takes up the impact force passively until the onset of loading at the elbow joint, i.e. 30 ms following first contact.
利用高速摄影技术研究了一匹以3.7米/秒速度小跑的马前肢的压缩情况。根据缩短情况的图表得出结论，与理论上僵硬的肢体相比，从下方纵向连续加载意味着更长的冲击时间和更小的冲击力。有人提出，肢体被动承受冲击力，直到肘关节开始加载，即首次接触后30毫秒。
