It takes a few clicks to get to the supplemental data movie: https://rs.figshare.com/articles/media/a_participant_running... You'd probably want to switch directions often!
The book "Imperial Earth" by Arthur Clark featured a circular cycle track on a low-gravity spaceship. The main protagonist was trying to train for earth gravity so he cycled around it very fast until he felt 1G
I didn't see any mention of having a spinning surface. A tapered cylinder "gravity gym" with adjustable angled walls, and variable speed spinning, could smoothly create much greater "gravity". Spin gravity would also enable body weight exercises, core exercises, stationary or small area cardio like exercise bikes, VR games, yoga, etc. Even sleeping. EDIT: I missed this: > but Moon-based centrifuges allowing locomotio…
Wild idea: build one on earth to simulate 1.1G (or higher; whatever would still be comfortable) and put gyms, hotels, swimming pool, living quarters, etc. in it. Being in it for extended periods of time would build up muscles and bones. That would likely be something that fitness people and professional athletes would be interested in. And it's a good dry run for building and operating these things on Mars and the Mo…

The ankle flex when the right foot lands makes me wince every single time. I wonder how much that's to do with the direction of gravity, the angle of their body looking not quite horizontal (and therefore 'weirding' the angle that feet hit the ground), and how much is to do with the individual's physiology.

Why did nobody do this yet? It would totally be a great prototype for stuff in orbit.
It would have to be big enough to avoid people getting dizzy, and even then it would still be a factor I think. That said, size/scale is less of a concern on the moon I would argue.

On the Moon, at normal pressure, humans shoud be able to get enough exercise in a jungle gym, or by donning a set of wings, flapping them to fly.

Maybe that doesn't matter.

Why? The bungee cord is only needed for earth gravity.
It's not a symmetric exercise, look at the feet. You'd probably want to keep the overall workout balanced by alternating periodically?

Closest thing I can think of is rotating houses / restaurants, but they go very slowly. It would have to be big enough to avoid people getting dizzy, and even then it would still be a factor I think. That said, size/scale is less of a concern on the moon I would argue.
