Why the study?
Despite known benefits of moderate exercise, concerns exist regarding potential negative effects of extreme endurance sport in participants older than 40 years.
Does running an ultramarathon induce acute biventricular dysfunction or ventricular arrhythmias in healthy master athletes?
Does running an ultramarathon induce acute biventricular dysfunction or ventricular arrhythmias in healthy master athletes?
Running a 50-km ultramarathon does not induce acute biventricular dysfunction or relevant ventricular arrhythmias in healthy master athletes, challenging concerns about the acute detrimental effects of extreme endurance sports.
No takes yet. Share an insight, caveat, or question.
Acute ultramarathon effects on master athletes' ECG and biventricular function require confirmation; leaves open clinical relevance and arrhythmia risk.
Cavigli et al. (2021) studied this question.
