Abstract
The purpose of the study was to compare the functional exercise capacity outcome between Horizontal and Graded Treadmill exercise training in Myocardial Infarction patients. Twenty patient participants who had myocardial infarction with Percutaneous Coronary Intervention (PCI) were recruited in the study. They were randomly assigned into Horizontal Treadmill (HT) Training Group or Graded Treadmill (GT) Training Group. Both groups underwent the same Phase II Cardiac Rehabilitation Program (CRP) which consisted of 2 sessions weekly that lasted for 8 weeks, including 10-minute warm up, 20-minute treadmill walking training, 10-minute upper arm ergometer, 10-minute resistance training using cuff weight and 10-minute cool down. 6-minute Walk Test was used as the functional exercise capacity outcome. All subjects were tested pre- and post-program. HT group needed to walk on a horizontal-treadmill (at gradient 0%); while GT group needed to walk on graded-treadmill (at gradient 13%). Both groups walked with the speed that could achieve the training heart rate for 20 minutes. Non-parametric test, that was Mann-Whitney U test and Wilcoxon test were adopted for the between group analysis and within group analysis respectively. After Phase II CRP, there were no significant difference between GT group and HT group in 6-minute walk distance (6MWD). However, there was significant gain in 6MWD after the program. It was concluded that there was no significant difference in the functional capacity outcome between Horizontal and Graded Treadmill exercise training in Myocardiac Infarction patients.
