  1. TP, time point; T0, baseline assessment; T1, assessment after 12 weeks; T2, assessment after 52 weeks; FEV1, forced expiratory volume in one second (%predicted); FVC, forced vital capacity (%predicted); VO2peak, oxygen uptake at maximum work rate (ml/min/kg); 6MWTD, six-minute walk test-distance (m); Powerpeak, maximum work rate (w/kg); PowerIAT, work rate at individual anaerobic threshold; HRIAT = heartrate (beats/min); SD, standard deviation; rmANOVA, repeated-measures analysis of variance
  2. aData violated the assumption of a normal distribution
  3. bGreenhouse-Geisser correction was applied
