Strength training not linked to ventricular arrhythmia in arrhythmogenic cardiomyopathy patients

Strength training does not appear to increase the risk of ventricular arrhythmias in patients with arrhythmogenic cardiomyopathy (ACM), a new study published online on September 10 in *JACC: Clinical Electrophysiology* reports. The research, which followed a cohort of individuals diagnosed with ACM, found no statistically significant association between engaging in resistance‑exercise programs and the incidence of life‑threatening heart rhythm disturbances.

The study’s findings address long‑standing concerns among clinicians and patients that weight‑lifting or other high‑intensity strength activities could trigger arrhythmias in this vulnerable population. By demonstrating that strength training is not linked to ventricular arrhythmia, the authors suggest that carefully supervised resistance exercise may be safely incorporated into the lifestyle of people with ACM, potentially improving overall fitness without compromising cardiac safety.

These results may influence future exercise guidelines for ACM patients, offering reassurance to those who wish to maintain an active lifestyle. Further research will be needed to confirm the findings across larger, more diverse populations, but the current evidence provides a promising step toward more nuanced, evidence‑based recommendations for physical activity in this high‑risk group.
