Every patients will achieve 3 constant work load test (CWLT) at 75% Wpic. The first CWLT will be realized without any ventilatory support. The 2 others CWLT will be achieved with non-invasive ventilation support using facial or nasal interface in a randomized order.

Endurance time (Tlim, in second) during Constant Work Load Test (CWLT).
Patients will achieve 3 Constant Work Load Test Under different conditions (1 without noninvasive ventilation and 2 with noninvasive ventilation using in a randomised order facial or nasal mask). Endurance time (sec) will be recorded at the end of every test.
Time frame: The outcome will be measure after every CWLT. The 3 CWLT will be carried out in different days, separate from 1 day minimum for a total time frame of 2 weeks maximum.
Comfort of different masks using numerical scale (0-10) after exercising with noninvasive ventilation.
The comfort of the different interfaces is assessed after every CWLT using numerical scale.
Time frame: The outcome will be measure after every CWLT achieved with noninvasive ventilation. CWLT will be carried out in different days, separate from 1 day minimum for a total time frame of 2 weeks maximum.
Dyspnea during CWLT using modified Borg Scale (0-10).
The dyspnea will be assessed every 30sec during CWLT. Results will be shown at Tlim (Tlim for the 3 tests) and iso time (defined as the Tlim or the shortest test).
Time frame: The outcome will be measure during every CWLT.The 3 CWLT will be carried out in different days, separate from 1 day minimum for a total time frame of 2 weeks maximum. Data will be collected every 30s during tests.
Exhaustion during CWLT using modified Borg Scale (0-10).
The exhaustion will be assessed every 30sec during CWLT. Results will be shown at Tlim (Tlim for the 3 tests) and iso time (defined as the Tlim or the shortest test).
Time frame: The outcome will be measure during every CWLT.The 3 CWLT will be carried out in different days, separate from 1 day minimum for a total time frame of 2 weeks maximum. Data will be collected every 30s during tests.
