1. To determine the most suitable exercise protocol for upper extremity aerobic exercise training, a widely used type of aerobic exercise to improve reduced upper extremity functional capacity in individuals with CIED and HF. 2. To investigate whether high-intensity intermittent upper extremity aerobic exercise training provides a more effective improvement in upper extremity functional capacity compared to moderate-intensity continuous upper extremity aerobic exercise training. 3. To determine the effectiveness of different types of upper extremity aerobic exercise training compared to lower extremity aerobic training alone in individuals with CIED and HF.
