Articles like this bother me...

Not sure what to make of these types of studies but I'd rather die doing something I love than die in front of my TV:

http://well.blogs.nytimes.com/2012/0...ou/?ref=health
http://au.news.yahoo.com/thewest/lif...rm-your-heart/

I'd like to know how they determine what they consider to be excessive exercise.

I think you need to read these articles more carefully.

They are talking about a change in 10-12% of athletes who regularly do things like marathons. Nor are they saying that being "in front of your TV" is better.

You can probably find studies linking spring water and fresh air to cancer. I'm in the best shape of my life since taking up cycling each day. Next best thing to living in the mountains (with all that toxic fresh air and spring water).

I was being a bit facetious in my post but I still find these types of articles vague and potentially harmful given the importance of exercise. Some of the other articles that referenced this study, which I did not link to, were less specific in detailing who the study may apply to and suggested that any intense exercise over 1 hour in duration could be bad for you. That could practically apply to almost everyone on this forum. No mention of whether the frequency of intense exercise matters, age, or how nutrition and recovery plans may influence the results. I'd have to read the actual study to see what factors were considered.

Edit:

One of the articles quoted a doctor saying that if you are going to run a marathon you should only make it a once in a lifetime event. How is it responsible for someone to make that sort of statement without having more evidence to back it up?

I saw an article years ago that found that if you exercised daily for (some certain amount of time) it would add about twelve years onto your life, but 10.5 of those years would be spent,,,,,,, exercising. There is benefits the rest of the time also though, so it still makes some sense.

------

It has been observed in many studies that the best way to induce longevity in mice is to keep them slim (light feeding) and inactive (with nothing to play with) in a cool environment, all of which slows their metabolism.

Living a longer-but-much-less-entertaining life (with a constantly-grumbling belly) is not exactly what I was dreaming of tho'.

I saw the "over 1 hour in duration" thing too.

One has to be very cautious about using such articles (reporting early/preliminary studies) as health advice.

I just want to be clear that I'm not concerned about working out too intensely lol. I do about 6-7 hrs of cycling a week, mostly short (30-50km), reasonably intense rides with longer rides on the weekend.. What bothers me about these articles is the broad recommendations and statements that are made based on early studies where the results are not yet fully understood.

The general rule is not to take medical/health advice from the media (whose primary goal is to attract eyeballs for advertising).

The only thing that bothers me about stories like this is that it is likely to give Joe Couchpotato yet another reason to remain inactive.

i think the difference lies in strenuous vs moderate exercise. Like biking full throttle for an hour vs a 10-15 mph pace.

It kinda makes sense that if you overwork your ticker on a daily basis, it may not last as long........

+1. They're out to provoke, and don't mind contradicting themselves or anyone else in order to get your attention. Bad news sells.

I'm pro-exercise and I'm not going to stop, but there's a lot of denial in this thread. I'm also a writer who's researched and written a couple of stories on this, the first one 10 or 12 years ago when I was routinely running 70+ miles a week, the second about a year ago. It's not likely anybody with reasonable exercise habits has to worry, but my cardiologist says I do show some worrisome signs. In my 40s I went into atrial fibrillation for no apparent reason, my resting pulse went up from 38-42 to the 90s, and my mile times got a minute to 1:20 slower. I switched to cycling because I had no previous record to compare to, and my heartrate and other vitals are under control, but it's not something that never happens.
But Scott, you keep thinking the media are out to get you...

It makes you wonder if running is harder on the body than cycling. I'm not a runner so I wouldn't know. Out of curiosity, do you know what your body fat percentage was around the period you experienced a/fib? Have you always been fit? Were you an endurance athlete in your teens?

Is it clear how much evidence he has? It's natural to defend something you love to do--people defend smoking. No point in being obtuse about it, though.

I was a football player and discus thrower in high school, but it was in the '60s, before cardio fitness was "discovered" (my dad used to walk a mile to work, and when he turned 40 his doctor told him to stop because he might have a heart attack. He ignored the advice and lived to 83...). Don't know my fat percentage when I went into fib, but it had been as low as 11 percent (had it measured for a story back when it was a rare thing to do). I weighed 204 at that time (I'm 6'4") but had gained 25 pounds before the a. fib.
I've always tended to exercise in spurts, six months on and two months off, but was fit and working out regularly when I converted to AF. It happened almost literally overnight, and several attempts to convert me back to sinus rhythm, including electroshock, failed. My younger brother, a former big-college basketball player, went into fib at almost exactly the same age, so there's certainly a hereditary thing there, but who knows who has that and who doesn't? He passed a dozen sports physicals, and I was a Special Forces Medic in Vietnam. Nobody saw anything until we broke down.

And you don't really know if your issues are the result of the exercise.

I don't think I'm being obtuse. I simply have a problem with a study consisting of only ~1600 people (iirc) and trying to prescribe recommended limits for the majority of the population, as evidenced by some of the quotes posted in the various articles. I'm not saying that there is nothing to be learned from studies into overtraining but I must admit I'm skeptical about the conclusions they are drawing at this point. I believe that there are too many factors to isolate (e.g. ethnicity, enviroment, nutrition, work, home life, genetics, etc) to offer strong words of caution to the general population. This is primarily the fault of the news outlets, for sure, as I'm sure the results of the study are enumerated more objectively. I still find some of the quotes from the various doctors interesting.

Is it possible that elite athletes could be damaging their hearts through excessive training? Sure, I can see that, but to suggest that you don't run more than one marathon in your lifetime or that more than an hour of vigorous exercise could be bad for you, seems a bit excessive. Once again, my post was about disliking how these articles present information - though I was also shocked by some of the quotes.

LOL, the media aren't out to get me, but I'm old enough to have witnessed a few rounds of "Eggs are good! No, eggs are bad!"-type health reporting...
