High Intensity Interval Training in Chronic Heart Failure

The Effect of High-intensity Interval Training and Moderate Intensity Continuous Training on Cardiopulmonary Functions in Chronic Heart Failure

The aim of this study is to investigate the effect of high-intensity interval training and moderate intensity continuous training on cardiopulmonary functions in chronic heart failure.

enroll chronic heart failure patients into 3 randomized controlled group
