Speed control mechanisms were investigated during overground locomotion in the dog. Swing and stance durations as well as stride length were measured for the four limbs simultaneously. Other locomotion parameters such as the mean velocity of the run, phase shifts, step length and the mean velocity of limb transport during the swing phase were calculated on the basis of the measured parameters. It was shown that the increase in stride length was almost linear in relation to the increase in locomotion velocity. There were similar changes in the stepping frequency although changes of this parameter were not strictly linear and depended on changes of step length. During moderate trotting the amplitude of limb movements was almost constant and the velocity of limb transport during the swing phase was minimal. Moreover in the symmetrical gaits spatial phase shifts between unilateral limbs were equal to zero, which means that hind and fore limbs were placed in the same point during successive steps.
在犬的地面运动过程中对速度控制机制进行了研究。同时测量了四肢的摆动和站立持续时间以及步长。根据测量参数计算了其他运动参数，如奔跑的平均速度、相位偏移、步长以及摆动阶段肢体移动的平均速度。结果表明，步长的增加与运动速度的增加几乎呈线性关系。步频也有类似变化，尽管该参数的变化并非严格线性，且取决于步长的变化。在适度小跑时，肢体运动的幅度几乎恒定，摆动阶段肢体移动的速度最小。此外，在对称步态中，单侧肢体之间的空间相位偏移等于零，这意味着在后肢和前肢在连续步骤中处于同一点。
