Abstract

Background and Aim: Heart disease patients need rehabilitation programs after surgery. The aim of the present study was to survey the effect of aerobic continuous training versus aerobic interval training on some heart morphological factors in Coronary Artery Bypass Graft Surgery (CABG) patients.
Materials and Methods: A total of 33 (30 men, 3 women with the mean age: 58.33± 9.50 and mean BMI: 27.05±3.55 kg/m2) POST CABG patients were divided into three groups of selected aerobic continues training (ACT, n=12), aerobic interval training (AIT, n=12), and control group (C, n=9) and participated in this training program three times a week for eight weeks. Echocardiography was used to investigate morphological factors such as Left Ventricle Diastolic Diameter (LVDD), Left Ventricle Systolic Diameter (LVSD), and Ejection Fraction (EF). Paired T test and One-way ANOVA were used to compare the means.
Results: The results showed that AIT and ACT have significant effects on LVSD (ACT: p=0.013, AIT: p=0.014). Also LVDD and EF had accretion as a result of AIT and ACT, but this increase was not found to be significant (LVDD: ACT: p=0.331, AIT p=0.138, EF: ACT= 0.487, AIT: P=0.186).
Conclusion: ACT and AIT for eight weeks cause identical and minor optimal changes in left ventricle structure and functional (contractility) after CABG.
