CG: control group, CTG: continuous training group; ITG: interval training group; EDD1: end-diastolic diameter at first evaluation; EDD2: end-diastolic diameter at the second evaluation; ESD1: end-systolic diameter at first evaluation; ESD2: end-systolic diameter at second evaluation; LVEF1: left ventricular ejection fraction at first evaluation; LVEF2: left ventricular ejection fraction at second evaluation; p = p-value of LVEF between the two study days.
