NYT Article: Exercise could increase heart risk for some

Answered on August 19, 2014
Created May 31, 2012 at 12:41 AM

Curious what the Paleohacks crowd has to say about this article:

http://well.blogs.nytimes.com/2012/05/30/can-exercise-be-bad-for-you/?hp

I am guessing the result hinges on whether the risk factors identified in the study really are indicative of future likelihood for heart problems.

What do you think?

EDIT: Link to the actual study: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0037887

Right, they found an interesting pattern, but that's pretty useless without the "why".

@Tyler that wasn't their objective. They allude to possible interactions with medication, but they can't reconstruct the conditions of past studies.

@mark as you say 60 is too few to draw useful conclusions. They spent a LOT of time analyzing the other studies and pooling the results on 4 tests. That's what I see being most useful here.

In the abstract, under methodology/principal findings: 'Sixty subjects were measured three times over a period of three weeks,...' 'Completers from six exercise studies were used in the present analysis' I believe they conducted their own sample study and used the other studies to add credibility to their findings.

@mark: this is pooled statistics on 6 studies previously run involving a total of 1687 individuals. These researchers did not run any tests. They were only doing statistics.

Study used 60 people. A population of that size is okay for a pilot study but not one you can draw general conclusions from that are applicable to the entire population.

My question is why those people responded adversely. Without more info from the full studies than just those few risk factors, we can't know.

If it bleeds it leads, but with this study it's hard to find the blood...

@Tyler, look at the bar graphs on individual test responses. This study seeks only negative responses. On any individual test about 100-150 responders out of 1600 saw worse results. Very few saw more than one negative response. I conclude that exercise is beneficial, but that's not what the study is looking for.

It's interesting that studies that differed so much all had adverse responders. Unfortunately, none of the individual studies are open for me to view, so I can't know whether or not everything else was well-controlled. The few risk factors they gave are not much to go on without more info.

If it's in the New York Times, ball it up and use it to start your next grill.

The full study shows that 7% of participants had an adverse response to exercise on a single CV test.

So there's a 93% chance that exercise will be beneficial.

Hunt-and-gather behavior is beneficial for most of us. Paleo practice is confirmed.
