The author compared 10 participants' self-selected walk-to-run transition speeds on a standard treadmill with those on a circular treadmill. The speed of the outer limb at walk-to-run transition on the circular treadmill and on the standard treadmill were very similar. Adaptive aftereffects from running and walking on the circular treadmill were also similar. When asked to step in place without vision, all participants inadvertently turned in circles following walking or running on the treadmill. The results of the present study suggest that the mechanisms controlling walk-to-run transitions are similar for the standard and circular treadmills and demonstrate the robust generalizability of locomotor aftereffects from running to walking. Adaptive control of speed, form, and direction may therefore share similar mechanisms for walking and running.
作者将10名参与者在标准跑步机上自行选择的从步行到跑步的转换速度与在圆形跑步机上的转换速度进行了比较。在圆形跑步机和标准跑步机上，从步行到跑步转换时的外侧肢体速度非常相似。在圆形跑步机上跑步和行走产生的适应性后效应也相似。当要求参与者在没有视觉的情况下原地踏步时，所有参与者在跑步机上行走或跑步后都会不自觉地转圈。本研究结果表明，标准跑步机和圆形跑步机控制从步行到跑步转换的机制相似，并证明了运动后效应从跑步到步行具有强大的普遍性。因此，步行和跑步在速度、形式和方向的适应性控制方面可能具有相似的机制。
