Effects of Upper Extremity Low Volume HIIT in Heart Failure

This study was planned to investigate the effects of upper extremity low-volume high-intensity interval training (LV-HIIT) on physical and cognitive function in patients with heart failure with preserved ejection fraction(HFpEF).The research was planned as a randomized controlled trial. Patients with clinically stable HFpEF at cardiology clinic will be included in the study. These cases will be randomly divided into two groups: intervention group and control grup. After 8 weeks intervention physical functions before and after treatment; functional exercise capacity, arm exercise capacities , peripheral muscle strength , fatigue cognitive functions; anxiety and depression and fear of movement will be evaluated.

Patients in the DV-HIIT group will receive training consisting of 4 minutes of warm-up and cool-down at 50% Wmax on an arm ergometer, 1 minute of training at 85-95% Wmax work intensity, followed by 6 interval training periods including 1 minute of active recovery periods at 50-70% Wmax, 2 days/week, totaling 8 weeks of training. The control group will be followed with standard medical treatment.
