That's because you don't need movement to stabilize your thinking and that expense of glucose depletes your resources. My experience is that ADHD kids need some sensori-motor input to help them reach their cognitive baseline. However, I don't agree with the study's conclusion because it tested a sort of "carpet-bombing" approach to the problem (i.e. lots of movement, injection of endorphins). I think that a much more efficient way, and I believe, more durable also, would be rock-climbing because in addition to the physical expense (i.e. energy output), it also stimulates very powerfully concentration/focus and the zones of the brain associated with it (i.e somewhere in the pre-frontal cortex) and can actually teach concentration and focus. I even wonder whether the best rock-climbers are not self-medicated ADHDs rather than so-called "adrenaline-junkies". Jumping off a bridge gushes adrenaline system-wide, climbing a face does not.
