Inclusion Criteria
Postoperative myocardial revascularization coronary patients who had undergone surgery a minimum of 12 months year All patients participants in a cardiovascular rehabilitation program for at least 12 months. Classified as eutrophic (body mass index from 18.5 to 24.9 kg/m2) or overweight (body mass index from 25 to 29.9 kg/m2).
Exclusion Criteria
smokers, pacemakers, complex arrhythmias, left ventricular dysfunctions, neurological and/or respiratory disturbances and had no visible alterations in thoracic and/our abdominal mobility, or accentuated structural deviations in the spine that might alter the dynamic respiratory.

- Primary Outcome Measures
Name Time Method The respiratory muscle strength was measured by an aneroid manovacuometer[2 minutes between each load (60 and 80% maximal inspiratory pressure)];The heart rate was measured using an electrocardiography[During the maximum inspiratory pressure measurement]
- Secondary Outcome Measures
Name Time Method To compare the maximal respiratory pressure with the predicted values. After the maximal inspiratory and expiratory pressures measurement were taken for each patient using an aneroid manovacuometer, these values were compared to the predicted values for the Brazilian population according to Neder et al. The predicted values were calculated for each patient utilizing the following formulas: MIP= -0.80 (age) + 119.7 + 0.48 (weight) and MEP = -0.81 (age) + 165.3.[after the subject did three repetitions of each maneuver with an interval of one minute between each repetition.]
