  1. The Activity Monitor measurements were taken over a 24-h period, and are given as mean ± SD. In all these measurements a higher value indicates better performance. The start and end times were when treatment started at t = 0 and ended at t = 12 weeks.
  2. Pt = P-value for differences over time; Pgt = P-value for interaction Group*Time
