  1. Differences in secondary endpoints (∆t, t1t0; t0 and t1) between MCT (moderate continuous training) and HIIT (high-intensity interval training) after three weeks of training. Illustration of Mann-Whitney testing. Mean values and standard deviations are depicted. Barthel index [pts, points]: score ranging from 0 to 100, 100 representing complete independence. FIM + FAM [pts, points]: functional independence/assessment measure (score ranging from 30 to 210, 210 illustrating no functional limitation). VCmax [l]: Maximal vital capacity. FEV1 [l]: forced expiratory volume in one second. KCO [%]: carbon monoxide transfer coefficient. P0.1 [kPa]: maximal inspiratory pressure at 0.1 s. PImax [kPa]: maximal inspiratory pressure. P0.1/PImax [%]: respiratory capacity. Mean values ± standard deviations are depicted. Differences were assessed with Mann-Whitney and t testing
