  1. ISWT: incremental shuttle walking test, ICT: incremental cycle test, CPET: semi steady-state cardiopulmonary exercise test, SpO2: oxygen saturation in blood measured by pulsoximeter, RPE: Borg scale for ratings of perceived exertion, CR-10: Borg scale for dyspnoea, VO2 peak: peak oxygen uptake, ***: p < 0.0001 compared to ICT and CPET, †: p < 0.05 compared to ICT. Mean (95% CI).
