Abstract Background During daily activities the active control of balance often is a task per se for example when standing in a moving bus . Other constraints like fatigue can add to the complexity of this balance task. In the present experiment we examined how moderate fatigue induced by fast walking on a treadmill challenged dynamic balance control. We also examined if the attentional demands for performing the balance task varied with fatigue. Methods Subjects n 10 performed simultaneously a dynamic balance control task and a probe reaction time task RT serving as an indicator of attentional demands before and after three periods of moderate fatigue fast walking on a treadmill . For the balance control task the real-time displacement of the centre of pressure CP was provided on a monitor placed in front of the subject at eye level. Subjects were asked to keep their CP within a target moving box moving .
