It is risky.
Stay fresh. Avoid repeating yourself. Don’t rant. Never preach. These would be the ‘rules’ of supposedly good blogs.
And, of course, doctors that dare to take a stance on health issues risk being perceived as pretentious. I get this.
So it is with trepidation that I write a follow-up to last week’s CW post about right ventricular damage immediately after an extreme race effort. Notwithstanding the pompousness concern, I also wish to avoid being labeled anti-exercise. Few believe more strongly in the healing powers of exercise.
But last Wednesday’s comments (both on the blog, Facebook and here on Dr. Val Jones’ BetterHealth blog) were just too good to let rest.
On the assessment of studies: Read more »

Dear Endurance Athletes,
Accept an apology in advance. You have endured so much from me.
Sorry.
Let’s at least start by agreeing that I can’t control the data.
Yes, you guessed it. There is unfortunately more bad news pertaining to the deleterious effects of endurance exercise on the human heart.
Again, I am sorry. Maybe re-phrasing the previous sentence will soften the blow. How about this: “Yet another study on endurance athletes suggests that exercise, like everything else in life, has an upper limit.”
Here goes, buckle up. Read more »

Before I even start, let me say this to my triathlete friends…
I really like you all. And…I am sorry for how I feel about your sport’s pinnacle, the Ironman triathlon. But I was poked into writing this post. When asked the question of whether the Ironman is safe for the middle-aged heart, what was I to do? Lie?
Each August, my hometown, Louisville, KY, gets overrun, over-swum and over-ridden with “Iron people.” No, these humans aren’t rust colored, or all that hardened, but they are indeed a determined lot. Triathletes, or iron people if you will, wake up before sunrise to swim, bike or run. Then they eat; some go to work (barely), and then they do the training thing again in the evening. Calling these athletes focused would surely be an understatement.
So it is each summer that I endure the same question: “Dr. Mandrola, did you do the Ironman?”
“No…I just ride bikes.”
But this year was different. Before I could launch into my usual dissertation on how training for Ironman-length triathlons causes excess inflammation, coronary calcium, atrial fibrillation, divorce, etc., etc., another question quickly popped up.
“What did you think of that guy who died during this year’s race?” Read more »

Recently, about 27,000 runners began the annual 26-mile, 385-yard (42.195 kilometers) mass run from suburban Hopkinton to Boston.
But if past marathons in Boston and elsewhere are any indication, perhaps up to 40% of these optimistic and determined souls will slam into a sudden sensation of overwhelming, can’t-do-this fatigue several miles (typically about five) before they get a chance to experience the glory of crossing the finish line.
It’s called “hitting the wall.”
Getting through, around, or over hitting the wall is part of the mystique of marathon running, although there’s a physiological explanation that’s not all that mysterious: when runners hit the wall, their bodies have run out of the carbohydrates needed to sustain intense physical activities like long-distance running.
Benjamin I. Rapoport believes many runners could avoid hitting the wall if they put a few key facts about themselves and their target marathon time into the online calculator he created, which can be found at www.endurancecalculator.com. The calculator will tell them how many extra calories they should get from pasta, rice, or other high-carbohydrate food or drink before (and in some cases, during) running a marathon. Read more »
