Is Too Much Exercise as Bad as Not Enough? What do you all think of this article recently published in the mfp blog?
http://blog.myfitnesspal.com/much-exercise-bad-not-enough/

Personally, I see it as another mainstream media attempt at making sure everyone in the world thinks they are doing life wrong. I get so sick of premature research pushed by media as gospel. After reading for a little while, you get skeptical of all research as it becomes so full of contradictions and qualifiers. But perhaps I only feel defensive because I regularly exercise 900 minutes a week. What do you think?

    Good to know, I never really read the blog before. Don't think I'm going to start.

    I read the linked article and recalled something about this issue that I had read last year. The article I read last year was about ultra endurance athletes especially the runners doing over 100 miles at a time. Cardiac remodeling as the heart adapts to the work load creates problems with the electrical system of the heart leading to poor heart function. There is also the problem of fibrosis as mentioned in the OP's linked article again resulting in poor heart function. Runners may recall Jim Fixx who died of cardiac problems. It was my thinking at the time that he suffered from arrhythmias although at that time we didn't know as much as we do now about cardiac remodeling. Again the stuff I read last year was about hardcore ultra endurance athletes--people really pushing the extremes.

    Yes, thickening of the heart walls causes issues of signals passing between chambers, but it's rare for natural athletes to experience this, but steroid users have been known to have such issues, recently pro bodybuilder Dallas Mccarver died at the age of 26 of a massive heart attack and his heart was almost 3x the weight it should have been. He was over 300lbs on stage and this alone was really not healthy.

    If you read up on Jim Fixx's family background you'll see that he probably prolonged his life through running as well.

    As for the ultra guys, I'm not sure I've seen any evidence of them having heart issues, do you have any information on increased risk or mortality? I'm curious because I've also wondered if that's even a healthy thing to think about let alone do! ;)

    I won’t comment on 900 minutes of exercise per week without more context to frame it. As far as the MFP blog, I’m not sure how much control they have over the content, whether it’s pushed to them from other sources or what, but it’s often as full of woo as a Dr. Oz show. I don’t even bother reading it after some of the clickbait garbage I’ve seen in it.

    ^This sums up everything I think about the MFP blog.

    I don't see anything wrong with the blog. It's posed as a question and clearly states that all data is preliminary and interpretations are just theories. What is wrong with sharing data when it's presented exactly for what it is.

    It's deceptive, people tend to read the headlines, forget that it's a question and don't understand the difference between weak evidence and strong support. They think anything published is somehow "proof". This is a deliberate attempt to mislead people, and not only that, it makes people distrustful of real scientific evidence because they didn't realize that what they were getting fed was either very specific or contradicted by most evidence.

    Whoa! So no one should publish anything that is 100% true unless they do so at a kindergarten level because people tend to have poor reading skills? Sorry, I am not on board with that and never will be.

    So that's what you got from my post? You've just demonstrated what I was referring too.

    Have to agree with what Wheel said on both counts. In no way did he say that everything had to be 100% true. Just when things get published (especially on a trusted site) without any actual basis IN truth - their reader base will still take it as 100% true without looking up on it with a discerning eye and understanding that the blog is not really moderated well and anything from actual science to snake oil can be put on there.

    That's exactly the point. The garbage they're publishing isn't "100% true", or even close to it. Most of it is the kind of ridiculous weight loss woo you see in magazines on the newsstands.

    I'm referring only to the link in the OP as that's the only blog I've read. What in that article isn't true or is misleading?

    I had not previously read about Jim Fixx's family background nor his personal medical history. I just now read a brief Wikipedia article which supports your view that he probably did prolong his life through running and other lifestyle changes; along with the genetic predisposition he had. Based on the autopsy results my thoughts on the cause of his death were incorrect.

    As for the articles I read last year, the indication was of evidence of heart problems developing but I don't recall that there were any specific deaths noted. One of the articles was from a university in England. I didn't get to finish reading the article. At the time I was following a cyclist named Mark Beaumont who circumnavigated the planet in 78 days and 14 hours if I recall his time correctly. I was trying to read up on how these people could train themselves for these types of efforts when I came across articles about the effects of this kind of ultra endurance activities.

    Thanks for the heads up on Jim Fixx. I learned something I did not know.
