Secondary Outcome

Comparison of the percentage of patients with SpO2 less than 90% during the study in 6MWT and 1STST
Comparison of the percentage of patients with a difference of over 4% in SpO2 at rest and during exertion at 6MWT and 1STST
Comparison of SpO2 at rest in 6MWT and 1STST
Heart rate at rest in 6MWT and 1STST
Maximal heart rate during exertion at 6MWT and 1STST
Comparison of post-test Borg scale in 6MWT and 1STST
Comparison of clinical characteristics of patients with and without a difference of MCID (1 point) on the post-test Borg scale at 6MWT and 1STST
Comparison of clinical characteristics of patients with a minimum SpO2 value of less than 90% and over 90% during exertion at 6MWT and 1STST
Comparison of clinical characteristics of patients with a difference in SpO2 between resting and exertion of over 4% and less than 4% at 6MWT and 1STST
