  • Chronic cardio and how it effects the body

    Hey guys,
    I am going to do a persuasive speech trying to sway people away from chronic cardio and towards low intensity and high intensity exercise. I am well aware that Mark has a few posts on chronic cardio and cortisol, but he doesn't provide sources and I can't use a blog as a source.
    I have been scoping out information, but does anyone know of any good studies or journals that talk about it?
    Thanks guys,
    Zach

    I would like to say for the record that I am not trying to get y'all to do my research for me and I can post up here what I find when I get it, just figured I would ask just in case someone knew a source of great information.

      "Cardio" may cause heart disease - Part I | Psychology Today - he references some studies, and I think even the NY Times recently published something about the negatives of marathon running, possibly in response to the same study

        Thanks for the reply, do you (or anyone else) know about Mark's other claims about cardio? Ie elevated cortisol, inflammation, muscle atrophy, etc and so on perhaps as well as the effects of elevated cortisol on the body?
        I have been searching for a good hour and haven't found much in terms of research, just forums and speculations (and not even that for a lot of them.)
        Ancdetal stories are all good, but as you guys know don't hold much water when actually trying to prove something.

          Try checking out Body By Science. Doug McGuff and John Little run the site, which is devoted to High Intensity Training - very similar to what Mark recommends. The best option for finding medical studies would be their book of the same title, though checking out their Articles would probably be a good place to start.

          Also, the article Less is Not Less at SaveYourself.ca, on the frequency of strength training and related gains might give you some scientific articles to look at, as well as places to search for others.

          I hope this helps,
          Aaron

            Body by Science is actually very different from PBF except for the fact that they both advise against chronic cardio. ;-)

              That's only because you don't know what's the same between the two.

                I make copies of this article by Rachel Cosgrove and give it to people running on the treadmill at the Y:
                Figure Athlete - The Final Nail in the Cardio Coffin

                (Not unsolicited; this is usually following a conversation about why they're not getting results after wasting hours every week running on that damned thing.)

                  I am curious about what everyone thinks constitutes chronic cardio. What heartrate percentage, and for what time frame? Running a marathon is obviously much different than running for a hour a couple times a week, so I wanted to get your thoughts...

                    Body by Science: Do one set of ultra-slow repetitions to failure per muscle group once per week - aim for 90 seconds time under load for one set. This typically amounts to about 5-8 repetitions per set (and in this case also, per week) per muscle group.

                    PBF: Work out 2-3 times a week, and in each workout aim for dozens of repetitions - for example 50 push-ups, 20 pull-ups etc. - which you perform in a circuit/superset like fashion. This amounts to several dozen, if not hundreds of repetitions per week and muscle group.

                    Quite a difference, I would say. As I posted elsewhere, it surprises me that Mark mentioned BBS on the last page of the PBF ebook. The similarities are the evolutionary reasoning behind the diet and the low-carb approach, but as far as exercising is concerned, the two could hardly be any more different.

                      Having spent years reading scientific journal articles you'd be surprised at the vast array of BS research that is out there. Much of it is paid for by private companies and/or carried out by research students. Having a list of journals that highlight the problems associated with chronic cardio is pointless as there are literally thousands that will say that it's great.

                      There is absolutely nothing wrong with empirical evidence.

                        I don't know, this sounds like lifting heavy things...

                        That's because you're looking for differences and not the similarities.

                          BBS, PBF, and Studies

                          1. BBS & PBF

                          They both advocate brief, intense exercise. 50 Push-ups take about a minute to a minute and a half to do, as well as other PBF exercises. Just look at the sprinting; brief, intense sets.

                          You are right, they are different MikeEnRegalia. But, they both advocate for a much more abbreviated program than a 'normal' weight lifting program.

                          And Body By Science has a sexy bibliography (if memory serves), which will probably help point the way toward science to support brief, intense (Primal) style workouts.

                          2. I'm just finishing up reading The New Evolution Diet by Art DeVany. The specific studies that he cites to back up the exercise program in the book are...

                          Insulin-like growth factor I in skeletal muscle after weight-lifting exercise in frail elders


                          Extremely short duration high intensity interval training substantially improves insulin action in young healthy males

                          &

                          Effect of low and high intensity exercise on circulating growth hormone in men

                          DeVany says that he has a longer bibliography on his site, but I haven't been able to find it

                          I hope this helps the science research ;-)

                          Cheers,
                          Aaron
