Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: Patients will perform two stair climbing sessions (each session include 108 steps) under two different conditions on the same day with at least 30 minutes of rest between the two sessions.

the order of the two conditions will be randomly assigned
Primary purpose: OTHER

Brief summary: Chronic obstructive pulmonary disease (COPD) is characterised by non-reversible bronchial obstruction associated with systemic disorders and comorbid factors. Dynamic hyperinflation during an exercise increase dyspnea and can reduce exercise capacity. Stair climbing is associated with prolonged dynamic hyperinflation and severe dyspnea in COPD patients. The aim of this study is to carry out the effect of an energy conservation technique on dyspnea to facilitate stair climbing.


Eligibility criteria: Inclusion Criteria:

* a diagnosis of COPD
* Dyspnea in daily living (2-4 on the modified medical research council dyspnea scale)
* clinically stable

Exclusion Criteria:

* exercise contraindication Any musculoskeletal problems, cardiovascular or neurological comorbidities that limits exercise.
* exacerbation during the study
* inability to climb 6 floors

Primary outcomes:
measure: Difference in Dyspnea at iso time and at time limit between the two sessions
timeFrame: The outcome will be measured before, at the end and every one minute during the stair climbing sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
Secondary outcomes:
measure: difference in time required for the patient to climb the 6 floors
timeFrame: The outcome will be collected at the end of each sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
measure: Difference in respiratory rate
timeFrame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
measure: Difference in inspiratory capacity
timeFrame: The outcome will be collected before and at the end of each sessions (within 2 minutes after the end). The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
measure: Difference in Cardiac Frequency
timeFrame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
measure: Difference in Oxygen Saturation
timeFrame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
measure: Difference in peripheral muscle oxygenation
timeFrame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
measure: Difference in tidal volume
timeFrame: The outcome will be collected before and at the end of each sessions (within 2 minutes after the end). The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
measure: Difference in muscular fatigue
timeFrame: The outcome will be measured before, at the end and every one minute during the stair climbing sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.
