So I was crusing around the blog-o-shpere the other day and I came across an article about cardio. I thought you would like it. Here is the link to the site.

It’s a longer article but a good read. especially if you can make sense out of research jargon which he does a pretty good job of translating into normal speak. Before I let you go, I am going to give you the Elite Performane & Fitness crib notes version of it.
This study looked at MRI scans of over 100 active marathon runners (active meaning the participant ran at least 5 marathons in the last 3 years) who had no history of heart disease or diabetes.
The researchers also made a control group of 102 age matched people with no history of heart disease, diabetes, or significant amounts of vigorous exercise. Here is what they found:
12% of the marathon runners had evidence of cardiac events
4% of the control group had evidence of cardia events
Runners: 5 cases of classic heart attack
Control: 2 cases of classic heart attack
Runners: 7 cases of non-classic heart attack
Control: 2 cases of non-classic heart attack
Before I let you go here is one more interesting stat pulled from the article
… in only 21 months of followup, 1 of 90 runners without LGE had a significant coronary event and 3 of 17 runners with LGE had a significant event. Significant events included two cases of collapse and EKG abnormalities after a race – similar to what felled Salazar and probably JIm Fixx. None died, but all were proved to have severe coronary disease by conventional angiography and were stented or had bypass surgery. This difference in event-free survival – 1% vs 18% -was significant by log-rank at the .0001 level…
There is a great amount of information in this article. I definately suggest you head over and read the full article.

Hey welcome back from the big Christmas holiday. I hope you got a chance to try out my special Christmas workout and enjoy your day. Now it’s time to get back to the meat and potatoes of things (at least for another few days before New Year’s anyways). Last time we talked, I shared with you an article on the link between cancer and sugar. In case you don’t remember you can check out the post here.
