Explore the relationship between exercise and heart health, including the benefits of both daily exercise and weekend warrior patterns. Discover surprising findings on the amount of plaque in the heart arteries of endurance athletes. Learn about the potential risks of excessive exercise through insights from marathon runners.
Both consistent exercise throughout the week and weekend-only exercise are associated with reduced cardiovascular risk compared to no exercise.
Long-term, intense endurance exercise may not necessarily result in a more favorable coronary plaque composition.

Benefits of Weekend Warrior Physical Activity
A study published in the Journal of the American Medical Association examined the effects of weekend warrior physical activity on cardiovascular health. The study analyzed data from 89,573 individuals and found that both consistent exercise throughout the week and weekend-only exercise were associated with a reduced risk of heart attack, heart failure, atrial fibrillation, and stroke compared to those who did not exercise. The study concluded that even intermittent weekend exercise can provide cardiovascular benefits.
Surprising Findings on Lifelong Endurance Exercise
A study conducted in Belgium investigated the relationship between lifelong endurance exercise and coronary atherosclerosis. The study included over 550 men and found that despite their high fitness levels and overall health, lifelong endurance athletes had more coronary plaque, including non-calcified plaque and proximal plaque, compared to individuals with a similarly low cardiovascular risk profile. The study suggests that long-term, intense endurance exercise may not necessarily confer a more favorable coronary plaque composition.
Understanding the Moderation of Exercise
While exercise has numerous health benefits, studies indicate that extreme endurance exercise may not always be advantageous. Findings from various studies, including the Copenhagen City Heart Study, have shown a J-shaped relationship between exercise intensity/duration and mortality risk. Moderate levels of exercise, such as 30 to 45 minutes of activity for 5 to 6 days a week, have been associated with favorable health outcomes. The key message is that exercise is beneficial, but excessive and extreme exercise may not provide additional advantages.
Exercise is a fundamental habit for optimal health and cardiac longevity. However, indications over the past decade suggest that endurance exercise may carry certain risks for the heart.
This week, Dr. Kahn takes us on a journey through time, from ancient Greek practices to a forward leap to his 2013 article, before delving into two new research studies on the elusive 'sweet spot' of exercise. The discussion will be highly practical, offering valuable insights to listeners seeking to optimize their health.
