Abstract

Aim.The aim of this study was to examine the effect of heart rehabilitation by resistance and endurance training on functional capacity and quality of life in male patients with myocardial infarction.

Background.Half of all people who have a heart attack will survive, but they might end up with a weakened heart and loss of functional capacity. It is necessary for nurses to gain essential knowledge to improve the patient’s quality of life and functional capacity.

Method. In this experimental study, 24 male patients with a history of myocardial infarction were recruited and randomly allocated to the endurance training group (n=8), resistance training group (n=8), and control group (n=8). Exercise training was implemented for 50-60 minutes at three sessions in weeks for eight weeks. Endurance training was implemented at 60-85% maximum heart rate on treadmill, while resistance training was implemented at 40-70% one repetition (RM) in three sets with leg press, calf elevation, and leg cruel exercises. Before and after intervention, functional capacity was assessed with modified Bruce test and quality of life was evaluated with SF-36 questionnaire for all groups under study. 

Findings.The results showed that there was a statistically significant difference in functional capacity of resistance (P=0.002) and endurance (P=0.03) training group with control group. However, there was not significant difference in quality of life between endurance and resistance training groups.

Conclusion.Resistance and endurance training can improve functional capacity in male patients with a history of myocardial infarction. However, resistance training is more effective than endurance training in improving the functional capacity and quality of life.
