本研究的目的是探讨步行-跑步转换速度区域运动能量成本与步长变异性之间的关系。10名受试者在四次跑步机训练中参与了这项实验。第一阶段用于让受试者习惯于在跑步机上行走或跑步。在第二次训练中，跑台速度以0.2 km.h-1的步长从6km.h-1增加到10km.h-1，以确定自由选择的步行和跑步之间的过渡速度(ST)。最后两次会议包括五次步行或五次跑步，选择的五种强度分别代表ST-1公里·小时-1、ST-0.5公里·小时-1、ST、ST+0.5公里·小时-1和ST+1公里·小时-1。在最后两次训练中收集呼出气体，并连续记录步幅持续时间。结果显示，在ST前，仅在自由选择的步态条件下，步长变异性显著增加。这些发现指出了另一个假说，而不是经典提出的将过渡描述为一种节能机制的假说。
The aim of this study was to explore the relationship between energy cost of locomotion and stride duration variability in the region of the walk-run transition speed. Ten subjects participated in this experiment during four treadmill sessions. The first session was used to habituate subjects to treadmill walking or running. During the second session the treadmill speed was increased from 6 km.h-1 to 10 km.h-1 in steps of 0.2 km.h-1 to determine the freely chosen transition speed between walking and running (ST). The last two sessions consisted of five walks or five runs conducted at five intensities selected to represent respectively ST-1 km.h-1; ST-0.5 km.h-1; ST; ST + 0.5 km.h-1; and ST + 1 km.h-1. Exhaled gases were collected during the last two sessions, and stride duration was continuously recorded. The results indicated a significant increase in stride duration variability before ST for the freely chosen gait condition only. These findings point to an alternative hypothesis to that classically proposed to describe a transition as an energy saving mechanism.
