FORT COLLINS, Colo. — Can an excessive amount of cardio train could be a dangerous factor?
A study by Colorado State University (CSU) examined ultra-athletes, in addition to those that have been merely reasonably energetic, to find out if an excessive amount of cardio may trigger coronary heart harm or coronary heart scarring.

Performed by Frank Dinenno, a professor in CSU’s Division of Well being and Train Science, and Nate Bachman, a doctoral scholar in Dinenno’s Human Cardiovascular Physiology Laboratory, the research examined 25 ultra-athletes in Colorado and 18 Coloradans who have been reasonably energetic.
The ultra-athletes have been wholesome people between the ages of 40 and 65 who had been coaching and competing for no less than 10 years in occasions like ultra-marathons and triathlons. The moderately-healthy management group consisted of topics in the identical age group who have been getting no less than 150 minutes of train per week.
After a battery of testing, the research discovered the ultra-athletes had higher cardiovascular well being than the management group and not one of the topics had any scarring on their hearts.
However, eight of the ultra-athletes had calcium deposits of their arteries, whereas solely two within the management group had such deposits.
Although a better proportion of the ultra-athletes had calcium deposits, the research discovered their cardiovascular well being was nonetheless higher than these within the management group general, main the research’s investigators to conclude that excessive quantities of cardio are usually not deleterious to 1’s well being.
“We didn’t discover proof that will make us suggest that individuals not train an excessive amount of,” mentioned Bachman. “The general advantages of train outweigh something we noticed.”
Nevertheless, researchers added that some individuals might produce other well being components, comparable to a household historical past of coronary heart illness, and that they need to focus on with their physician earlier than turning into ultra-athletes.
“There are most likely some individuals who shouldn’t be doing this a lot train,” Bachman mentioned.
The research additionally discovered that seven of the eight ultra-athletes who had calcium deposits have been males. Dinenno and Bachman mentioned that is per different research which have proven that calcium tends to indicate up earlier and at greater ranges in males than in girls.
“Along with serving to us perceive some fundamental and medical cardiovascular physiology of ultra-endurance athletes, this was a real collaborative effort with the UCHealth Coronary heart and Vascular Heart,” mentioned Barry Braun, a co-author and head of the Division of Well being and Train Science. “We labored collectively, from asking the preliminary questions, to creating refined measurement of cardiac construction and performance, to modifying the ultimate manuscript.”
