Adherence
Regular moderate-to-vigorous exercise (≥4 hours/week) significantly reduces the long-term risk of sudden cardiac death in women, despite a transiently elevated risk during acute exertion.
For women concerned about heart health, engaging in at least 4 hours of moderate-to-vigorous exercise per week (such as brisk walking, jogging, or swimming) significantly lowers the long-term risk of sudden cardiac death. While there is a tiny, transient increase in risk during the actual act of vigorous exertion, this risk is negligible and is completely offset by the protective benefits of regular exercise.
Regular exercise may significantly minimize this small transient risk and may lower the overall long-term risk of sudden cardiac death.
Why this rating
Large prospective cohort (Nurses' Health Study) with long follow-up, though observational design limits causal proof.
