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.
Interventions
During the session of stair climbing, patients will perform a break at least of 5 seconds every 3 steps.
OTHERcontrol session
Patients will realize one session of stair climbing at their own pace

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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Difference in Dyspnea at iso time and at time limit between the two sessions | 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. | Difference in dyspnea using Modified Borg Scale (0 - 10 points) 0=no dyspnea ; 10 = maximal effort |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Difference in respiratory rate | 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 respiratory rate (cycles per minute) will be measured breath-by-breath using a Respiratory Inductive Plethysmography |
| Difference in inspiratory capacity | 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 inspiratory capacity (Liters) will be measured using a portable spirometer |
| Difference in Cardiac Frequency | 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 Cardiac Frequence (bpm) using a pulse oximetry |
| difference in time required for the patient to climb the 6 floors | 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. | Difference in time (seconds) will be evaluated using a stopwatch |
| Difference in peripheral muscle oxygenation | 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. | Muscle oxygenation (arbitrary unit) will be evaluated using Near-infrared spectroscopy technology. |
| Difference in tidal volume | 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 tidal volume (Liters) will be measured breath-by-breath using a portable spirometer |
| Difference in muscular fatigue | 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. | Difference in muscular fatigue using Modified Borg Scale (0 - 10 points) 0=no muscular fatigue ; 10 = maximal effort |
| 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 Oxygen Saturation |
