I really love feeling of zone in triathlon. On the other hand, there are chronic fatigue, shortening of telomeres, overtraining as emphasized in "Top Ten Reasons Not to Run Marathons" by Arthur De Vany.
Message from my prefrontal cortex with reward/risk analysis tells me stay away from triathlon, but my passion(reminiscence of dopamine from previous experience) drives me toward triathlon. Before plunging into reckless risky behaviour, I want to study whether "Is there a possibility that cardiac damage, spine degeneration, brain damage are result of carbohydrate glycation? not from triathlon itself.
Question is: "Are there studies of these bad effects in paleo practitioner with proper training involved in triathlon ironman"?
in feb 2010 there was a study that showed 100% of long term marathoners had cardiac fibrosis and the control group had none. cardiology literature is beginning to look here because of the astounding number of cardiac morbity and mortality in what appear to be healthy runners
Caveat emptor if you run distance.
You're not going to get a lot of encouragement from this crowd, are you? Let's propose a Paleo-triathlete compromise.Oxymoron... Stop all the medium and long steady state traininng sessions.Do two HIIT workouts each week, rotating swim,bike and run. Lift weights twice a week. Do a SHORT steady state run, bike or swim once a week. Compete in the teentsey-weenseyiest distance triathlon you can find in your area ONCE a year. Save all remaining testosterone/growth hormone for your spouse or significant other.
I highly doubt such studies exist, either Re: paleo endurance athletes or endurance athletes eating beaucoup carbs vs. sedentary individuals eating a similar quantity of carbs and getting fat (if you are just talking %s of macros, those studies probably do exist). But if we assume, for the sake of argument, that training to maximize performance in endurance sports is intrinsically unhealthy and leads to all sorts of problems...is there any chance you could be happy swimming, running and cycling in more moderate "doses"?
This is an interesting topic. I just came across this pilot study that suggests older endurance athletes actually have longer telomeres. Due to the small sample size, more research needs to happen. http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0052769
I have often wondered why endurance athletes look so much older, is it because of excessive sun exposure? Or does an extremely low body-fat percentage give an older appearance?
