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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| energy conservation technique | Experimental | Patients will perform one session of stair climbing of 108 steps (corresponding to 6 floors). |
|
| Control session | Other | Patients will perform one session of stair climbing of 108 steps (corresponding to 6 floors). |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| energy conservation technique | Other | During the session of stair climbing, patients will perform a break at least of 5 seconds every 3 steps. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Difference in Dyspnea at iso time and at time limit between the two sessions | Difference in dyspnea using Modified Borg Scale (0 - 10 points) 0=no dyspnea ; 10 = maximal effort | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| difference in time required for the patient to climb the 6 floors | Difference in time (seconds) will be evaluated using a stopwatch | 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. |

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

| Difference in respiratory rate |
Difference in respiratory rate (cycles per minute) will be measured breath-by-breath using a Respiratory Inductive Plethysmography |
| 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. |
| Difference in inspiratory capacity | Difference in inspiratory capacity (Liters) will be measured using a portable spirometer | 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. |
| Difference in Cardiac Frequency | Difference in Cardiac Frequence (bpm) using a pulse oximetry | 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. |
| Difference in Oxygen Saturation | Difference in Oxygen Saturation | 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. |
| Difference in peripheral muscle oxygenation | Muscle oxygenation (arbitrary unit) will be evaluated using Near-infrared spectroscopy technology. | 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. |
| Difference in tidal volume | Difference in tidal volume (Liters) will be measured breath-by-breath using a portable spirometer | 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. |
| Difference in muscular fatigue | Difference in muscular fatigue using Modified Borg Scale (0 - 10 points) 0=no muscular fatigue ; 10 = maximal effort | 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. |
