- Cardiologist Dr. Mohammed Alo talks about the impact of extreme endurance sports on arterial health.
Being less active or sedentary for sure isn't healthy. We also know that endurance and aerobic exercise are good for the heart. But how about the other end of the spectrum, where athletes do the extreme?
Dr. Mohammed confirms that endurance athletes are more predisposed to increased coronary artery calcification and that they have more rates of cardiac arrhythmias, atrial fibrillation, and dilated heart chambers. What do these conditions imply? Are the benefits of pushing one's limits worth it? Find out in this conversation.

I ran my first marathon at age 40, and ran about one or two annually, a little over 20 in total, along with many 1/2 marathons, along with many long training runs. During the pandemic, I had a cardiac calcium scan, expecting to see a low score. Mine was 1,000+. I ran to improve my health. I have no symptoms, and testing revealed no blockages. What good came out of this is that I became 95% vegan, 5% vegetarian, on the way to becoming 100% vegan.
Dr. Greger made a video about this topic. He thinks the culprit is the increased caloric intake and with that, typically the higher saturated fat intake. For example, take a professional triathlete. In a full block training day, they could swim, run and bike themselves into a caloric expenditure of 6000 or 7000 calories. More likely than not, people who do this will have a diet that contains a lot of junky fast and processed foods because in this contex, calorie dense foods are king. So the shear volume of trans fat, saturated fat and cholesterol is likely to be relatively high.
This is a very good hypothesis. And it makes sense because we know that saturated fat increases CVD risk independent of calories once you get up to and exceed a certain threshold of grams per day. Someone can be in a caloric deficit but if they’re eating enough saturated fat which puts them over the threshold for risk, risk increases. Likewise, someone can eat triple the calories a normal person eats because they’re an extreme athlete, and the saturated as a % of calories may stay the same, but in absolute terms their saturated fat intake gram for gram is 3 or 6 times greater than the average standard Americans diet which is already bad/high.
I don't know about that, it's a bit of a cheap hypothesis. The cycling and running communities preach carbs over all else, and mostly fuel their training with such - I kinda hate their obsession with gels. For people who train a lot, it's not the same as a cycling club stopping at a bakery; but there's also not going to be one mold that all endurance athletes fit into. I'd want to see some pretty comprehensive data to point the finger at the easy villain that is saturated fat.
Lack of sleep, extra stress and inflammation from extended exercises needs adequate replacement of antioxidants, micro and macronutrients. I believe it is from inflammation from a cascade of factors that include added stressors like lack of sleep, water, lack plants ( whole ) that provide the anti aging compounds to negate some of these stressors.
Really interested to learn there's an association between CAC score and endurance training. A great topic for future discussions if at all possible, please.
I'm interested in that topic too as an endurance athlete in his mid 50's with a calcium score just under 400. Many of the people I train with in my age group also have high calcium score regardless of cholesterol numbers.
Hi bro.
Im wondering what's ur calorie intake. 🙏
Would u like to share it with us.
The difference lingers in having a heart attack at the age of 70 instead of 80.
I am a 70 yr old.im in very good physical condition.. I recieved a cac score of 1263.i lift weight till utter failure and some cardio that is short but intense.. never any symptoms, cramps or chest pain.After extensive testing my cardiologists diagnosis was the arteries were open and the calcium had either manifested itself on the outside of my artery walls or within it..he could not give me a good explaination as to why..i was cleared to go back working out.. could this condition be exercise induced?
Interesting! How did you discover that you don't have plaque?

My cardiologist did a nuclear stress test and a sonogram.. talk about relief.. I went from the original cac tests being stopped and told u need to see a cardiologist right now, to being cleared to go back to normal activity..frankly originally he appeared skeptical when I told him I had no cramps chest pains etc lifting weights doing cardio etc...
