Abstract

Aim.The aim of this study was to compare the eight weeks of combined and aerobic training on body composition and strength in cardiac patient post- coronary artery bypass graft.

Background. Cardiac rehabilitation improves fitness and clinical status in cardiac patients after coronary artery bypass.

Methods. In this randomized clinical trial, 20 cardiac patients under CABG surgery in  Tehran Heart Center were randomly divided into two groups, combined and aerobic training. The protocols of combined group included two movements  of the upper limbs (Pectoralis Major and Deltoid muscles) and two movements of  the lower limbs (quadriceps and Hamstring muscles) by 3 sets/10Rep and  aerobic group  with 60-85 minute exercises at 70-85% peak HR in three sessions per week for 8 weeks. Functional capacity (VO2peak), strength, body weight, BF percentage and WHR were assessed before and after the training protocol. The collected data were analyzed using the Independent and Paired t-tests.

Findings. There was an elevation of functional capacity following, combined (p<0.05) and aerobic (p=0.027) training with a significant further increase in the combined group (p=0.016). The strength increased significantly after combined training (p<0.05). The BF percentage with no significant difference between two groups, decreased significantly following the both training protocols (p<0.05).  

Conclusion. Combined aerobic-resistance training and aerobic training to improve functional capacity in Post CABG cardiac disease.However, Combined aerobic and resistance training is more effective than aerobic training in improving the functional capacity (cardiovascular fitness) and strength.
