以前没有关于快步行走和以幼儿自己选择的速度跑步时的能量消耗和感知努力的报告。54名参与者(年龄8-11岁)在一个有标志的学校操场上进行了1500米的快步和跑步，并得到了简单的指导，让他们要么快走，要么慢跑。在跑步过程中，孩子们获得了更高的平均速度和更大的总能量消耗(p<；.001)。然而，两种活动之间的感知努力没有差别(p>；0.05)。这些发现表明，在某些条件下，孩子们发现跑步和快步走一样容易，尽管速度和能量消耗要高得多。
There are no previous reports of energy expenditure and perceived effort during brisk-walking and running at speeds self-selected by young children. Fifty four participants (age 8-11 years old) performed 1500 m of brisk-walking and running in a marked school playground, and were given simple instructions to either 'walk quickly' or to 'jog'. During the running the children achieved higher mean speeds and a greater total energy expenditure (p < .001). However, there was no difference in the perceived effort between the two activities (p > .05). These findings suggest that under certain conditions children find it just as easy to run as they do to walk briskly, even though the speed and energy expenditure is significantly higher.
