FORT COLLINS, Colo. — Can too much aerobic exercise can be a bad thing?

A study by Colorado State University (CSU) examined ultra-athletes, as well as those who were simply moderately active, to determine if too much cardio could cause heart damage or heart scarring.

The study, published in the journal “Atherosclerosis,” found that while some ultra-athletes showed some minor calcium buildup in their coronary arteries, they were still healthier overall than a control group of people who only got moderate exercise.

Conducted by Frank Dinenno, a professor in CSU’s Department of Health and Exercise Science, and Nate Bachman, a doctoral student in Dinenno’s Human Cardiovascular Physiology Laboratory, the study examined 25 ultra-athletes in Colorado and 18 Coloradans who were moderately active.

The ultra-athletes were healthy individuals between the ages of 40 and 65 who had been training and competing for at least 10 years in events like ultra-marathons and triathlons. The moderately-healthy control group consisted of subjects in the same age group who were getting at least 150 minutes of exercise per week.
