  1. Week 1: familiarization week
  2. Note that the extra high duration group had an increase in session number per day on weeks 10, 11, and 12. Rats in the control group walked per 15 min once a week at 10 m/min. The experimental week for rats in the moderate duration, and high duration groups, consisted of five consecutive days of training sessions, with 24 h of recovery between sessions, followed by 2 days of recovery. The experimental week for rats in the extra high duration group consisted of daily training sessions with 24 h recovery between sessions from week 2 to week 9. On weeks 10, 11, and 12, they had 6, 4, and 2 h recovery, respectively, between training sessions on the same day
