Change in mean self-rated fatigue from before walking (pre) to after walking (post) by experimental condition (continuous vs. intermittent; N = 30) with standard error bars

The overall interaction was significant (P < .001) owing to a greater increase in VASF scores in the continuous condition relative to the intermittent condition. The prewalking scores were statistically equivalent across conditions, whereas there was a significant difference between the postwalking scores of the two conditions (P < .05). VASF, Visual Analogue Scale of Fatigue. Note: Possible VASF scores range from 0 mm to 100 mm, but the vertical axis was truncated to save space.
