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.

Difference in tidal volumeOne week

Difference in tidal volume will be measured breath-by-breath using a portable spirometer (Spirodoc, MIR)

Difference in peripheral muscle oxygenationOne 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)
