Evolution of Pulsed Oxygen Saturation During Interval Training Compared to Continuous Training in COPD Patients
Study Details
Study Description
Brief Summary
A problem often observed during exercise training is oxygen desaturation exclusively during exercise in some patients. In the case of exercise-induced desaturation, it may be suggested to train these patients in interval training to limit exercise-induced desaturation. Interval training consists of alternating active phases of short duration (often 30 seconds to 1 minute) followed by a short active or passive recovery phase of equivalent duration to the previous phase. Investigators therefore hypothesise that interval training on a cycloergometer or treadmill can limit exercise-induced desaturation in COPD patients.
The aim of the study is to observe the evolution of pulsed oxygen saturation between a continuous training session and a interval training session.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Continuous training session
|
Other: Continuous training session
Continuous training consists of a 5 minute warm up, 5 minute cool down and 20 minutes of moderate intensity work. The workload is set at 60% of the patient's maximum power
|
| Interval Training session
|
Other: Interval training session
Interval training consists of a 5-minute warm-up, a 5-minute cool-down and 20 minutes of alternating 60 seconds of high-intensity work (100% of the maximum power recorded in the incremental test that was carried out when the patient was admitted to the pulmonary rehabilitation department) and 60 seconds of unloaded pedalling or rest.

Outcome Measures
Primary Outcome Measures
- Difference in oxygen pulsed saturation [One week]
Difference in minimum saturation during both exercise, the measurement will be performed with a pulse oximeter (Spirodoc, MIR)
Secondary Outcome Measures
- Difference in oxygen pulsed saturation [One week]
Difference in mean pulsed oxygen saturation and the time spent with a pulsed oxygen saturation below 90% during the two training sessions. The measurement will be performed with a pulse oximeter (Spirodoc, MIR)
- Difference in peripheral muscle oxygenation [One week]
Muscle oxygenation (arbitrary unit) will be evaluated using Near-infrared spectroscopy technology. the measurement will be performed with a Near Infrared spectroscopy (Portamon, Artinis Medical Systems)
- Difference in respiratory rate [One week]
Difference in respiratory rate will be measured breath-by-breath using a portable spirometer (Spirodoc, MIR)
- Difference in tidal volume [One week]
Difference in tidal volume will be measured breath-by-breath using a portable spirometer (Spirodoc, MIR)
- Difference in inspiratory capacity [One week]
Difference in inspiratory capacity will be measured using a portable spirometer (Spirodoc, MIR)
- Difference in Dyspnea [One week]
Dyspnea peak during exercise using the modified Borg scale 0-10, 0 no dyspnea, 10 maximal dyspnea
- Difference in muscle discomfort [One week]
Muscle discomfort peak during exercise using the modified Borg scale 0-10, 0 no dyspnea, 10 maximal dyspnea
