Combined Arm-leg Ergometer Endurance Training Versus Cycle Ergometer Endurance Training in Myocardial Infarction
Sponsor: Riphah International University
Summary
Myocardial infarction (MI) often leads to reduced cardiorespiratory fitness, poor exercise tolerance, and decreased quality of life. Conventional rehabilitation mainly uses cycle ergometer training but may not adequately improve upper-limb function needed for daily activities. This randomized clinical trial aims to compare the effects of combined arm-leg ergometer endurance training and cycle ergometer training on cardiorespiratory fitness, exercise tolerance, and quality of life in post-MI patients. The study will be conducted in cardiac rehabilitation centers in Pakistan using 40 medically stable post-MI patients divided into two groups. Group A will receive combined arm-leg ergometer training, while Group B will receive cycle ergometer training. Sessions will be conducted 3 times weekly for 6 weeks. Outcomes will be measured using VO₂ peak, 6-minute walk test, and MacNew HRQOL questionnaire, with data analyzed through SPSS version 25.

arm-leg ergometer training
Each session will last between 30 minutes and will include a warm-up and cool-down period. The intensity of the training will be maintained at a moderate level, corresponding to 50-70% of the individuals heart rate reserve or a score of 11-14 on the Borg Rating of Perceived Exertion (RPE) scale, which reflects "light to somewhat hard" exertion. This protocol involves the simultaneous use of both upper and lower limbs, which may elicit a higher cardiovascular demand and greater systemic oxygen consumption, thereby potentially enhancing improvements in VO₂ peak and overall cardiovascular efficiency
traditional cycle ergometer training
same frequency, intensity, and duration of training as Group A, but the type of exercise will be limited to lower limb cycling on a standard stationary bike. This mode of training targets aerobic endurance primarily through leg muscles, which is the conventional method used in postmyocardial infarction rehabilitation
