New research from the University of Leeds indicates that male endurance athletes over the age of 50 may face an elevated risk of serious heart rhythm disturbances during or after exercise. The study, published in the European Journal of Preventive Cardiology, highlights concerns for this specific demographic, particularly for those with existing heart muscle scarring.
Researchers monitored a group of 106 healthy male runners and cyclists using wearable activity trackers and implantable heart monitors. The findings revealed that approximately one in four participants experienced episodes of ventricular tachycardia, a rapid heart rhythm that can be life-threatening if sustained. Notably, three out of four athletes who experienced these episodes showed signs of myocardial scarring.
“Our study shows that exercise was only associated with a risk of developing abnormal heart rhythms in those who were already high risk due to heart scarring,” stated Wasim Javed, the lead author of the study. This suggests that while exercise is generally beneficial, it may act as a trigger for dangerous heart rhythms in older athletes with underlying conditions.
The research underscores an alarming trend: about 90% of exercise-related sudden cardiac deaths occur in males over 40, often without prior warning signs. Despite this, health experts from the Cleveland Clinic and the American Heart Association advocate for regular physical activity, emphasizing that even moderate exercise can significantly reduce the risk of cardiovascular disease and stroke.
Regular physical activity, even as little as 30 minutes most days, is associated with improved heart health and enhanced circulation. Cardiologists affirm that exercise strengthens the heart and supports overall cardiovascular wellness.
Javed added, “Athletes who developed abnormal heart rhythms were not exercising more or harder than athletes without abnormal heart rhythms. This suggests that exercise itself is not the cause but could act as a trigger for dangerous heart rhythms in those already facing heart challenges.”
As a precaution, researchers recommend older male athletes, especially those with extensive competitive backgrounds, to undergo regular cardiovascular screenings. They should also seek medical advice if they experience symptoms such as unexplained dizziness, palpitations, or breathlessness. Utilizing wearable heart-monitoring devices may provide early detection of irregular rhythms.
“Exercise is safe and has immense benefits — but athletes in this group should have regular health checks to make sure they stay healthy,” Javed concluded.
This study serves as a crucial reminder of the importance of monitoring heart health, particularly for older athletes engaged in intense physical activity. While endurance training can yield great benefits, awareness of potential risks is vital for maintaining long-term health.
