Exercise Intensity
Boosting Myocardial Preconditioning With High-Intensity Intradialytic Exercise: A Preliminary Study
London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's
15 participants
Sep 22, 2025
INTERVENTIONAL
Conditions
Summary
Patients receiving regular hemodialysis (HD) treatments are at a higher risk of cardiovascular events and death as HD can cause a decrease in the pumping of the heart during treatment called 'stunning'. Intradialytic exercise has emerged as a safe and effective non-drug approach to improve cardiovascular health and is now recommended for patients undergoing HD. It is currently advised that HD patients engage in at least 30 minutes of moderate to vigorous exercise three times per week. This study will evaluate the impact of exercise intensity in the HD population and determine if high impact exercise can offer better protection to the heart against HD-induced myocardial stunning.

Interventions
Intradialytic exercise has emerged as a safe and effective non-drug therapeutic approach to improve cardiovascular health and is now recommended for people undergoing hemodialysis treatment. Administration of a higher intensity exercise could offer better cardio-protective mechanisms and if the efficacy of cardiovascular protection is proven, it could be developed as a therapeutic option in the dialysis population.
