The Double-Edged sword of Exercise
For decades, the medical community has championed exercise as a cornerstone of a healthy lifestyle. From grade school PE classes to public health campaigns, Americans are constantly reminded of the benefits of physical activity. Exercise combats obesity, strengthens bones and muscles, elevates mood, and reduces the risk of chronic diseases like type 2 diabetes. However, emerging research indicates that pushing the limits of physical endurance may present unforeseen cardiac challenges, particularly for elite athletes.
Exercise is “an notable way to maintain health” throughout life, improving fitness and reducing the risk of heart-related conditions like high blood pressure and high cholesterol. Yet, a paradox exists: prolonged, intense exercise can lead to what’s known as “athletic heart,” a remodeling of the heart that could perhaps increase certain risks.
Understanding “Athletic Heart”
The term “athletic heart” refers to a collection of physiological adaptations that occur in response to intense and prolonged physical training. These adaptations include an increase in the size of the heart’s chambers, particularly the left ventricle, which is responsible for pumping blood to the rest of the body. The heart muscle itself may also thicken. While these changes can improve cardiac output and enhance athletic performance, thay can also, in some cases, lead to heart rhythm abnormalities, fibrosis (scarring of the heart tissue), and other complications.
These changes in heart structure and function among people who engage in large amounts of exercise has led to the term “athletic heart”. Often, the American Heart Association recommends “150 minutes of moderate-intensity exercise, such as brisk walking, or 75 minutes of vigorous-intensity exercise, such as running, each week. It also recommends muscle strengthening exercises at least twice per week.”
Coronary Artery Calcification (CAC) in Athletes
Another area of concern among elite athletes is coronary artery calcification (CAC). CAC is the buildup of calcium in the arteries of the heart, a process that typically occurs in older adults or those with risk factors for coronary artery disease. The presence of CAC increases the risk of heart attack and stroke. Athletes, despite their otherwise healthy lifestyles, are not immune to this process.
The presence of “Coronary artery calcification,or CAC” is a concern for elite athletes. CAC increases the risk of heart attack or stroke. some athletes may consider medications like aspirin or statins; though, risks “vary from person to person,” so anyone concerned about CAC should talk to their doctor.
Balancing Act: Exercise and Heart Health
Despite the potential risks associated with extreme exercise, it’s crucial to emphasize that regular, moderate-intensity physical activity remains one of the most effective ways to maintain a healthy lifestyle. The benefits of exercise for the general population far outweigh the potential risks. Exercise helps maintain a compliant heart and prevents stiffening. A compliant heart will expand a lot more as it fills with blood and, in turn, pump out more blood with each heartbeat. A stiff heart has difficulty filling up with blood and has difficulty pumping blood through the body.
Such as, if someone does not exercise routinely, their heart “will become stiff” and not pump blood as well as it once did.
The Importance of Routine and Starting Late
It’s never too late to start exercising and helps promote physical and mental health and help your heart stay young throughout your life.
Generally, routine exercise throughout adulthood encourages the heart to “remain strong and flexible” even in old age. Even if someone were only to begin regularly exercising in their 40s to 50s, it is possible to “reverse some of the effects” of sedentary aging.
A 2018 study of 53 sedentary people mostly in their early 50s found that those who participated in a two-year exercise training program using a combination of running, cycling and elliptical exercise had hearts that “became more compliant” compared to the hearts of those who did not exercise.
What training methodologies are commonly used to minimize teh risks associated with athletic heart in elite athletes?
Elite Athletes and Heart Health: An Interview with Dr. Evelyn Reed
Archyde News Editor: Welcome,Dr. Reed. Thank you for joining us today. We’re here to discuss a critical topic: the impact of extreme exercise on heart health, notably for elite athletes. Could you start by explaining the concept of “athletic heart”?
Dr. Evelyn Reed: Certainly. “Athletic heart” refers to the structural and functional changes that occur in the heart due to intense and prolonged physical training. These include an increase in the size of the heart’s chambers,especially the left ventricle,as well as potential thickening of the heart muscle itself. While these adaptations can improve cardiac output and athletic performance, thay also carry potential risks.
Archyde News Editor: That’s a critical distinction. What are some of the potential risks associated with athletic heart, and how do they differ from healthy exercise?
Dr. Evelyn Reed: One key concern is an increased risk of heart rhythm abnormalities and, in some cases, fibrosis, or scarring of the heart tissue. The difference between athletic heart and healthy exercise lies in the intensity and duration. Moderate exercise,as recommended by organizations like the American Heart Association,is generally safe and beneficial. However, the extreme demands placed on the heart by elite athletes can push it beyond its normal functional limits.
Archyde News Editor: I see. Another aspect mentioned in the research is coronary artery calcification (CAC). How does this factor into the discussion?
dr. evelyn Reed: Yes, CAC is a notable concern. It involves the buildup of calcium in the arteries of the heart, increasing the risk of heart attack and stroke. While CAC is often associated with older adults, it’s also a factor to consider for elite athletes, who, despite their otherwise healthy lifestyles, are not immune to the calcification process. If athletes or anyone is concerned they should always consult ther doctor.
Archyde News Editor: The article also touches on the importance of regular, moderate-intensity exercise for the general population.Can you elaborate on the benefits of this kind of exercise compared to the potential risks of extreme training?
Dr. Evelyn Reed: Absolutely. Regular, moderate exercise is a cornerstone of a healthy lifestyle. It combats obesity,strengthens muscles and bones,elevates mood,and reduces the risk of chronic diseases. It helps keep the heart compliant, allowing it to pump more efficiently.
Archyde News Editor: So, it’s about finding a balance. It’s never too late to start exercising. What about older adults, or those who may not have been athletic in their younger years? Can they still benefit?
Dr. Evelyn Reed: Absolutely! Research shows that starting exercise even in your 40s or 50s can reverse some of the effects of a sedentary lifestyle. Regular exercise can help the heart remain strong and flexible,improving overall cardiovascular health. It’s a matter of incorporating movement into your routine.
Archyde News Editor: A final, thought-provoking question for our readers: given the potential risks for elite athletes, what steps should be taken to ensure a balance between performance and heart health?
Dr. Evelyn Reed: Regular cardiac monitoring is crucial which should be done. Utilizing training methodologies like zone 2 training, which emphasizes lower-intensity work for a majority of the training time, is common in the elites. Consulting with a cardiologist and implementing a balanced training program can help minimize risks while maximizing athletic potential.
Archyde News Editor: Dr. reed,thank you so much for providing such insightful information. This has been a very informative discussion on a critical topic.
