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.

Conditions

• COPD
• Exercise
• Pulmonary Rehabilitation
• Desaturation of Blood

Interventions

Type	Name	Description
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
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.
