Why the study?
Physical exercise counteracts pharmacological cardiotoxicity in breast cancer, but close individualization is needed to maximize benefits in remote programs. Using heart rate variability to prescribe high-intensity training had not been tested in this population.
Does a high-intensity exercise program guided by HRV improve physiological, physical, and psychosocial outcomes in breast cancer patients after chemotherapy and radiotherapy compared to preplanned exercise or usual care?

This study protocol outlines a randomized trial to evaluate whether HRV-guided high-intensity exercise improves cardiotoxicity and other outcomes in breast cancer survivors.
