The marathon. An epic struggle of the individual against his/her own body. A kind of “Mt. Everest” for athletic practice, it exacts a sizable toll on anyone who dares attempt it. (The first marathon man died after all.)
The seasoned athlete knows and respects the physical claim of a marathon, and it is substantial even for the best trained. But marathons are becoming increasingly popular in the last few years. Once limited to the athletic elites and diehards, marathons are now the stuff of social events and charity drives. We’re all for the social element of sport, and we’re suckers for a good cause like anyone. But this recent popularity has changed the face (and emergency support requirements) of marathons. While we believe that everyone’s got to start somewhere, we definitely believe this ain’t the place.
A study presented Wednesday at the American Academy of Neurology’s annual meeting suggests that regular physical exercise may offer a protective benefit against mild cognitive impairment.
How cognitively impaired are we talking here? Think forgetting where you left your keys, remembering events, appointments, or to check Mark’s Daily Apple every day (as if you could ever forget that!) or recalling the details of a conversation.
Conducted as part of an ongoing study of aging, researchers from the Rochester, Minn.-based Mayo Clinic surveyed 868 people ages 70 to 89 about their exercise habits between ages 50 and 65. Researchers also screened all participants for signs of mild cognitive impairment.
A few weeks back my Chronic Cardio post got a lot of response and initiated some great discussion. Since it’s one of the cornerstones of the Primal Blueprint philosophy (and an obviously popular one at that), I thought it was worth more time and tender loving attention.
And why wouldn’t anyone want to hear that real exercise doesn’t mean endless hours on that torturously boring treadmill? News like this is like sunlight bursting in, choirs of children singing, shackles collapsing open and crashing to the ground. Hordes of celebratory folk parade through the gym, penny whistles and fiddles playing, ale mugs in hand, goats and cows in the merry mix. Get off that treadmill and join us, for the love!
A study published Tuesday in the online edition of the American Heart Association’s journal Circulation suggests that frequent exercise can reduce the risk of death in men.
To examine the link between fitness and mortality, Veterans Affairs (VA) researchers gathered fitness data on 15,660 male VA patients undergoing treadmill testing for various medical reasons. The men, who had an average age of 60, where then assigned to one of four groups based on their level of fitness.
According to the results, mortality risk directly correlated with fitness level, with men in the highest fitness category being the least likely to die when compared to their less fit counterparts. For example, across the eight year study period, 44% of the men in the least fit group died, compared to 30% in the moderately fit group, 15% in the highly fit group, and 8% in the very highly fit group.
We all know that we need to exercise to be healthy.
Unfortunately, the popular wisdom of the past 40 years – that we would all be better off doing 45 minutes to an hour a day of intense aerobic activity – has created a generation of overtrained, underfit, immune-compromised exerholics. Hate to say it, but we weren’t meant to aerobicize at the chronic and sustained high intensities that so many people choose to do these days. The results are almost always unimpressive. Ever wonder why years of “Spin” classes, endless treadmill sessions and interminable hours on the “elliptical” have done nothing much to shed those extra pounds and really tone the butt?
Don’t worry. There’s a reason why the current methods fail, and when you understand why, you’ll see that there’s an easier, more effective – and fun – way to burn fat, build or preserve lean muscle and maintain optimal health. The information is all there in the primal DNA blueprint, but in order to get the most from your exercise experience, first you need to understand the way we evolved and then build your exercise program around that blueprint.
Like most people, I used to think that rigorous aerobic activity was one of the main keys to staying healthy – and that the more mileage you could accumulate (at the highest intensity), the better. During my 20+ years as a competitive endurance athlete, I logged tens of thousands of training miles running and on the bike with the assumption that, in addition to becoming fit enough to race successfully at a national class level, I was also doing my cardiovascular system and the rest of my body a big healthy favor.
Being the type A that I am, I read Ken Cooper’s seminal 1968 book Aerobics and celebrated the idea that you got to award yourself “points” for time spent at a high heart rate. The more points, the healthier your cardiovascular system would become. Based on that notion, I should have been one of the healthiest people on the planet.
Unfortunately, I wasn’t – and that same mindset has kept millions of other health-conscious, nirvana-seeking exercisers stuck in a similar rut for almost 40 years. It’s time to get your head out of the sand and take advantage of your true DNA destiny, folks!
The first signal I had that something was wrong was when I developed debilitating osteoarthritis in my ankles…at age 28. This was soon coupled with chronic hip tendonitis and nagging recurrent upper respiratory tract infections. In retrospect, it is clear now that my carbohydrate-fueled high-intensity aerobic lifestyle was promoting a dangerous level of continuous systemic inflammation, was severely suppressing other parts of my immune system and the increased oxidative damage was generally tearing apart my precious muscle and joint tissue.
The stress of high intensity training was also leaving me soaking in my own internal cortisol (stress hormone) bath. It wasn’t so clear to me at the time exactly what was happening – in fact it was quite confusing, since I was doing so much of this so-called “healthy” aerobic exercise – but I had no choice but to give up racing, unable to train at anywhere near the intensity required to stay at an elite level.
To make ends meet…
