Cardiovascular Damage Resulting from Chronic Excessive Endurance Exercise
Overview
Paper Summary
This review suggests that excessive endurance exercise, such as marathon running, might have negative impacts on the heart, including changes to the heart muscle and arteries. However, much of the evidence comes from animal studies or is correlational in nature, and there are conflicting findings in the literature. Moderate exercise is still much better than no exercise.

Identified Limitations
Rating Explanation
This review summarizes existing evidence and raises an important question, but relies heavily on correlational data and animal studies. It does not provide definitive proof that excessive endurance exercise is harmful to humans, and more research is needed. The reliance on animal models and correlational evidence limits the paper to a 3.
