Rehabilitation Training With Music-support & Exercise Tolerance in COPD and CRF Patients.

"All patients will perform the usual training by listening a piece of music of the same duration as the training. The patient will be able to choose among 4 different musical proposals corresponding to 4 different styles: rock, modern, jazz and classical. The song chosen by the patient will be the musical support for all the sessions of training on the cycle ergometer. The musical pieces will be composed with a constant rhythm (bpm=60) which, from a tonal point of view, will echo the pedaling movement. The constant rhythm will be superimposed on musical patterns in the form of loops in the styles mentioned. The musical support will assume a priming (activation) and dragging (synchronization) function, facilitating movement planning/synchronization and creating a pleasant context in which to carry out training"

All patients will perform 12 to 14 supervised sessions depending on the center they belong to (5-6 sessions/week) each consisting of 30 minutes of exercise at the cycle ergometer plus 3 minutes of warm-up and 3 minutes of recovery. After a warm-up phase at 0 W, the initial workload will be set to 60% of the theoretical maximum. Intensity increases or decreases of 10 W will be made according to the criteria of Maltais et al (workload will be increased when patients will report dyspnea and/or leg fatigue as ≤3 on a Borg scale modified to 10 points of perceived effort. The training load will remain unchanged if the Borg score is 4 or 5 and will be reduced for scores ≥6). Patients will have to maintain a pedaling frequency between 55 and 60 rpm.
