RESUMEN
Training with resistant exercises has been proved to be beneficial for patients of ischemic cardiopathy. This kind of training increases working capacity, provided the exercise is maintained in the necessary threshold to avoid starting a chest angina. Nevertheless, there is no clear evidence of an increase in the blood flooding of the myocardio, the left ventricle function or the heart electric stability as a consequence of the said training. It's our opinion that the principal reasons for this lack of evidence are: a) insufficient research, b) the existence of technical difficulties for developing certain phases of the necessary research, and maybe that, c) some exercise programs are not sufficiently long and intense and to induce myocardial adaptation. The purpose of this study is to determine if a long program of physical exercise training could produce a better blood irrigation and ventricular function as well as restore the electric stability. This approach to the problem is justified by the recent finding of adequate methods which really and definitely answer these questions with the results obtained through properly controlled physical exercise.
