Hi Chris,

Welcome to the forum.

I think your understanding of the functional MRI results from the CYCLE trial is correct. Hopefully they will discuss these (and other) results when the final report is eventually published.

It is hard to know how many are still doing cycling according to the Alberts/Ridgel protocol. I'm currently doing about 30 to 40 minutes of unassisted stationary cycling first thing every morning.
