Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CPET submaximal without EPAP
Will be collected clinical and anthropometric data of the participants and they are packaged in self-evaluation form. Evaluation of pulmonary function at rest will be rescued from patient charts. When carried out for over six months, will be repeated by the researchers. Patients will conduct incremental CPET of 5-10W/min limited by symptoms (FEV1 \<1L-5W or FEV1\> 1L-10W) (Visit 1). After a period of 2-7 days the CPET will be performed submaximal with 75% of the peak load reached in the incremental CPET (visits 2-3). During the visit without EPAP will be maintained using the facial mask applied without resistance.

When carried out for over six months, will be repeated by the researchers. Patients will conduct incremental CPET of 5-10W/min limited by symptoms (FEV1 \<1L-5W or FEV1\> 1L-10W) (Visit 1). After a period of 2-7 days the CPET will be performed submaximal with 75% of the peak load reached in the incremental CPET (visits 2-3). The application of EPAP (10cmH2O) via face mask (Vital RHDSON Signs®, New Jersey, USA) will be randomized with the help of opaque envelopes to be given in one visit. IC serial measurements will be carried out before, during and immediately after the exercise.
CPET submaximal with EPAP
The expiratory positive pressure is applied through silicone mask (RHDSON Vital Signs®, New Jersey, USA) containing one-way valve and a resistance mechanism expiratory positive expiratory pressure generator adjustable 5-20 cm H2O (Spring Loaded) (Vital Signs® , New Jersey, USA). The mask one headgear will be comfortably adjusted to face being used to prevent air leakage, and the pressure level gradually adjusted to the level of 10 cm H2O.
