Weird NASA Question

Listen up! I went to space camp YEARS ago and there was an apparatus that had you harnessed onto an axis which spins 360 degrees, surrounding this axis was a closed circuit treaded walkway. The point of this thing was to buckle yourself in, and run, end-over-end, to help get rid of interstitial fluid which builds up in the feet and legs. You could imagine it being the antagonist to a hamsters wheel where YOU would be the one spinning and not the wheel around you…

Well anyway, the whole point of this was to ask if anyone knows what this contraption is called and if they know anything more about it than myself.

PS NO it is not Multi-Axis Trainer(MAT), nor is it a 1/6 Gravity Chair, 5 Degrees Of Freedom (5DF) Chair, or a Manned Maneuvering Unit-1 G Trainer (MMU). And it is definately not an Underwater Astronaut Trainer (UAT).

Like I said weird, I know, but any help would be appreciated…
