What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| submaximal functional capacity | functional capacity evaluated by six-minute walk test | Change from Baseline in functional capacity at seven days and thirty days after surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| capacity functional | cardiopulmonary exercise testing ( VO2) | evaluated 40 days after surgery | 
| respiratory muscle strength | Both PImax and PEmax were obtained using a pressure transducer | Change from Baseline in respiratory muscle strength at seven days and thirty days after surgery | 
| lung function | assessed by spirometry (FVC and FEV1) | Change from Baseline in lung function at seven days and thirty days after surgery |
