Study on Increased Coronary Plaque in Marathoners

Interesting article that just came out. No conclusive findings due to the inability to have randomized controls, but some concerning results for those who marathon long term.

Also, discussion that moderate and less frequent cardiovascular exercise confers all the CV benefits without any of the CV detriments.

Good reason to start taking Omega 7’s I’d say
.

In additional to regular dental hygiene I use a fluoride wash, haven’t had an issue and I’ve been running marathons for years.

Interesting. I read as much as I could and skimmed some. Seemed to me something like 26 of the 50 runners were smokers?!? Although, they said that was not a big difference compared to the non runners? I believe the stat was 6/30 for non runners. I may be off by a few. To me that seems weird. Of the runners I know, none of them, including myself smoke. Interested to see exactly how they picked these runners. I would like to see a study with many more runner and non runners. Maybe some younger ones too. I can easily see how long term high intensity and duration could cause heart problems. Plaque wouldn’t have been my first guess. I just wonder if these numbers are skewed by smoking. Perhaps I should re-read this more carefully.

One more thing in life I will choose to ignore.

Yeah, 39.1% of control were prior smokers vs. 52% of marathoners. They used some trickery with the claim that they were “similar in smoking history” - just the fact they didn’t have a large enough sample size to reach statistical significance. And if you don’t have statistical significant then there’s no justification to talk about a significant difference. It would be interesting to know, however, how well the 26 ex-smokers correlated with the 30 guys who had lesions.

I’d also point out that the marathoners were about 4 years older, on average, than control. Again, not statistically significant, but given that age is a dominant factor in heart disease, worth pointing out.

The combination of those two things stacks the deck against the marathoners, statistical significance or not. . I’d like to read the actual full paper, because I have some other issues with what I read there, but I don’t want to throw them under the bus without reading the actual study plan.
