It is already Wednesday! This week is flying by for me, it has been a really fun week so far though. I hope you are all having a wonderful day.
As you all know, I’ve been reading various things about heart health recently. I don’t even know why or how I got interested. However, one thing led to the other and I wanted to share with you some of the more interesting stuff I’ve been reading.
One of the more interesting groups of articles I stumbled upon was about the impact of endurance training on your heart. I read various articles (that essentially said the same thing) and here is a link to one of the good ones. Studies have found that endurance races, such as Olympic length triathlons, can cause long term and even fatal damage to your heart and arteries.
Long term training for endurance events can lead to abnormalities in the structure and function of the heart and releases the same biomarkers found during cardiac arrest. These changes usually return to normal within a week. However, if training continues in the longer term it can lead to irregular heartbeat, scarring or patchy myocardial fibrosis.
However, with all that said there are relatively few direct deaths in endurance athletes every year; the statistics are one death for every 100,000 people who run a marathon in the USA. And there are approximately 2 million American’s running marathons every year. (Isn’t that number amazing!!! So many people!)
Balance is the key, as with anything as the health benefits rise as you start to train and taper off as you over train. US Center for Disease Control and Prevention recommends only 2.5 hours a week of moderate exercise and 75 minutes of vigorous activity (like running). Seems like nothing when I think about how much training I do and have done. However, it also seems like a number that is more achievable for many people who make the excuse that they don’t have time.
What are your thoughts on endurance training and health? I think a lot of you get way more out of your training over and above the physical benefits. Endurance events are very “mental” and I believe probably good for you psychologically. Do studies like these change how you view training?
