Comparing Low-Volume and High-Volume High-Intensity Interval Training for Adults with Chronic Heart Failure

What this Trial Is About

This research aims to evaluate how low-volume versus high-volume high-intensity interval training affects functional capacity and quality of life in patients with chronic heart failure. The study focuses on patients with reduced ejection fraction and seeks to compare the impact of different exercise volumes combined with standard medical treatment. Participants will be randomly assigned to one of three groups for an 8-week period one group will receive low-volume high-intensity interval training on a treadmill twice weekly along with usual care another group will perform high-volume high-intensity interval training twice weekly with usual care the third group will continue with standard medical treatment only. Both exercise programs vary in session duration and interval length. Throughout the study, participants will undergo assessments including a 6-minute walk test and 2D echocardiography at the beginning and end of the 8 weeks. Quality of life will be measured using the Minnesota Living with Heart Failure Questionnaire. The study monitors these outcomes to understand how exercise volume influences heart function and patient well-being during treatment.
