[Early physical conditioning of patients surgically treated for myocardial revascularization. Influence on the functional capacity].
OBJECTIVE
To evaluate the early physical conditioning (PC) effect [initiated 15 days after the myocardial revascularization surgery (MRS)] in the functional capacity.


METHODS
Twenty-two male patients (mean-age of 52y-o), divided in two groups (A and B, 11 patients each), were studied. Group A started PC 3 months after MRS (phase III), with a training intensity of about 70% of the maximum heart rate reserve, during three months, three sessions per week with one hour duration. Group B started PC 15 days after the MRS (fase II), with a training intensity up to five metabolic unities, three times a week, 1 hour and 15 duration. The post-MRS period of three months was designated as the time I (beginning of fase III) and six months as time 2. Stress test, Kraus-Weber flexibility test, coxo-femural flexibility test (flexion, elevation and abduction) and scapule-umeral flexibility test (flexion, extension and abduction) were applied.


RESULTS
The maximum oxygen uptake and the total work increased significantly from time 1 to time 2 in both groups, but there was no significant difference between the two groups, either in time 1 or 2. Flexibility in the Kraus-Weber test and in the scapule-umeral flexibility test when in flexion, were significantly greater in group B than A, in both times (1 and 2). Other flexibility variables studied show no significant difference, neither between the studied groups nor in the times 1 and 2 of evaluation.


CONCLUSIONS
Early PC after MRS increased the value of two variables that measure flexibility. However, it has not increased other flexibilities variables and the aerobic capacity.
