Comparing Upper Arm Aerobic Exercise Training Methods to Improve Arm Function in Heart Failure Patients with Cardiac Devices

What this Trial Is About

This research evaluates different upper extremity aerobic exercise training methods to improve arm function in people with heart failure who have cardiac implantable electronic devices like ICD or CRT. It aims to find the best exercise protocol by comparing high-intensity interval training with moderate-intensity continuous training and lower extremity aerobic training. The study focuses on improving upper extremity functional capacity and overall fitness in this specific group of patients. Participants are randomly assigned to one of three groups high-intensity interval upper extremity exercise, moderate-intensity continuous upper extremity exercise, or lower extremity aerobic exercise. The high-intensity protocol includes warm-up, repeated intervals at 80-90% workload, active rest periods, and cool-down over 20 minutes. The moderate-intensity group exercises continuously at 70-80% workload for 20 minutes. The lower extremity group trains for 40 minutes at 70-80% peak oxygen consumption. During the study, participants maximal and functional arm exercise capacity and cardiorespiratory fitness are measured at the start and after 8 weeks. Additional assessments include muscle strength, daily living activities, and quality of life. The trial monitors progress and effects of the exercise protocols over 8 weeks to understand which training best supports arm function and overall fitness in heart failure patients with implantable devices.
