I just returned home after a week of high-altitude livin’ in Jackson Hole, Wyoming. Two great runs bookended my trip: On day one of my vacation in Jackson, I went for a light and easy morning jog to stretch my legs. Twenty minutes into my jaunt through the neighboring community of Wilson (population: 1,300; elevation: 6,100 feet), I looked up at Teton Pass, the mountain road that climbs 2,200 vertical feet at grades of up to 10 percent and cuts through the rugged range that divides the Equality State from the Gem State, and was overwhelmed with a curiosity to run to the top. (In summers past I have busted my quads riding to the summit.) A breathtaking view of the valley floor from an elevation of 8,400 feet was my reward. Incredible.

This run was just a warm-up for when I would play King of the Mountain(s) at the end of my vacation. Starting from Teton Village (elevation: 6,300 feet) at Jackson Hole Mountain Resort, I darted up a trail that wraps its way to the top of Apres Vous Mountain (8,500 feet), then crossed over and trekked up to the tippity snow-capped top of Rendezvous Mountain (10,500 feet), and then descended just a wee-bit to Gondola Summit (9,000 feet). This epic trail run sometimes seemed like a Sisyphian challenge (especially the trudge up the steep, slippery, and bowl-shaped Sublette chutte), but was ultimately — because of the difficulty of the trek, the views afforded from the mountain peaks, the wildlife that I found myself surrounded by, and the quiet solitude of such an adventure  — the highlight of my trip.

Having just returned home, I want to share some noteworthy news items from the past week that I am just now having a chance to catch-up on:

** Philosophy Talk, one of my favorite local radio programs, gets some much deserved recognition, courtesy of the L.A. Times article, Yeah, these philosophy professors will give it some thought. “Thank you for thinking.”

** Gretchen Reynolds of the NYT highlights an important and oft overlooked concern about the health of endurance athletes: The sometimes obsessive weight iusses of male and female athletes:

In [a] study published earlier this year in the Clinical Journal of Sport Medicine, 223 Swedish Olympians (125 men and 98 women) were weighed, measured and asked about their eating habits. The thinner athletes, many of them from endurance sports, reported more episodes of wild weight swings and eating disorders than other athletes. Even more startling was that the eating and weight problems were most common among the thin male athletes. The women didn’t worry about their weight nearly as much. In fact, according to Dr. Hagmar Magnus, a physician at Karolinska University Hospital in Stockholm and the study’s lead author, “the female Olympians ate a lot and planned meals well. The men didn’t.”

Magnus says the lessons of the study are broad. For one, “we’ve all been paying a great deal of attention to female athletes, trying to help them avoid eating disorders,” he says. “We need to start doing that for men.”

In addition, “the best female athletes in Sweden eat quite well, which suggests that good eating is a real competitive advantage,” Magnus says. “As a physician, I see many female athletes, not quite so elite, who have eating problems. That may be what has kept them from the top ranks. I’d love to get the message to them, you can eat your way to greatness.”

** Walking book clubs?! Exercise the mind and the body to maximize cognitive and bodily health, says Dr. Arthur Kramer, Professor of Psychology and the Director of the Biomedical Imaging Center at the University of Illinois, in this interview with Alvaro Fernandez of SharpBrains.

** And follow-this up with another fascinating AF/SharpBrains discussion about why and how smart people do really dumb things, like the Harvard students who paid $204 for a $20 bill. Wha?! Ori Brafman, co-author of Sway: The Irresistible Pull of Irrational Behavior, explains “the different hidden forces” and “psychological undercurrents” of our decision making processes here.

If you bump into Ultramarathonman Dean Karnazes at your local Whole Foods, I bet it won’t be in the supplement and food bar aisle… 

In “Nutri-lize This,” National Geographic Adventure magazine reports that “the fittest man in the world,” and many more elite and endurance athletes, “are questioning the benefits of vitamins and supplements, opting [instead] for all natural [foods].”

As reporter Karen Asp summarizes:

Packaged powder may goose you during a hard run or ride, but eating au naturel, it seems, can help separate the winners from the also-rans. Suzanne Girads Eberle, a sports dietitian and authors of the highly regarded handbook, Endurance Sports Nutrition, says “Vitamins and minerals don’t give us energy. That comes from carbs, proteins, and fats in healthy foods.”

So what to eat? “Some dietary standouts” include low-fat milk, edamame, peanut butter, lentils, albacore tuna, and lean red meat.

Slow carbs to run fast… Pass me some muscat melon!

Additional reading: Real Thought for Food for Long Workouts by Gina Kolata compares the nutritional science market of recovery products to the benefits of eating real food after engaging in vigorous exercise.

Chocolate milk is just about the best thing an endurance athlete can drink after a hard workout.

Forget the fancy packaging and multi-syllabic scientific terms that are used to describe the nutrition benefits of expensive powders, gels, and other liquid concoctions found at General Nutrition Stores. Muscle Milk and its similar-marketed cousins of the “endurance fuel” family have nothing on moo milk and Hershey’s syrup. Seriously.

With the increasing demand and use of protein and carbohydrate drinks aimed at the hard-core athlete, the New York Times published comments from an un-scientific taste and performance test of leading post-activity sports drinks designed to optimize recovery. In “Gear Test: How About a Spin and Tonic?“, Gatorade Protein Recovery Shake, Met-Rx RTD, EAS Myoplex Read-to-Drink, Powerbar Recovery, and Cytopsorts Recovery Drink were sampled.

I could not help but notice how expensive all these drinks were. And the image of chugging any of these drinks after a workout brought to mind a picture of a mechanic topping-off the fluids in a race car after a hard drive. It seems as if the marketing of these products appeal to an idea in our head of our bodies as machines that need to be re-fueled with fancy chains of lab-designed amino acids, carbs, and proteins.

Then I remembered of hearing an anecdote that Michael Phelps drinks Carnation Instant Breakfast between races. For Michael Jordan, “It’s gotta’ be the shoes!” For this Michael, maybe, “It’s gotta be the milk!”

In 2006, the International Journal of Sport Nutrition and Exercise Metabolism published a study conducted at Indiana University that found:

Chocolate milk contains an optimal carbohydrate to protein ratio, which is critical for helping refuel tired muscles after strenuous exercise and can enable athletes to exercise at a high intensity during subsequent workouts. It is a strong alternative to other commercial sports drinks in helping athletes recover from strenuous, energy-depleting exercise. (Source.)

How effective? Co-author Joel Stager says, “Chocolate milk was nearly twice as effective than the synthetic products [such as those taste-tested by the NYT] as a recovery product.” (Source.)

“The researchers found that cyclists who drank chocolate milk during the rest period were able to bike nearly twice as long before reaching exhaustion than those who consumed the carbohydrate replacement drink.” (Source.)

Bonus: “And the athletes liked the taste a lot better.”

Double bonus: Chocolate milk is relatively inexpensive, especially when compared to the $3-4 cost of a single-serving of Muscle Milk.

What is so great about chocolate milk? And what about that sugar? That can’t be good for you, can it? Well…

Chocolate milk has the ideal ratio of carbohydrates to proteins — 3 or 4 grams of carbs to 1 gram of protein — for optimal post-exercise recovery. Regular milk does not have this same ratio.

It’s not just the ratio of carbohydrates to proteins that makes a difference. There seems to be something special about milk itself that cannot be replicated in the lab. “Endurox, which has the same carb-to-protein ratio as chocolate milk, fared poorly” in the study.

What gives? One researcher supposes that “It may have to do with the different composition of the sugars in the milk. The sugars in the milk may be better absorbed in the gut than those in the Endurox.” (Source.)

Whatever the reason, Mother Nature and Hershey’s know what’s best. Pass me some milk and chocolate syrup!

Further reading: Swallow This by Gretchen Reynolds discusses the trends and science of post-workout recovery nutrition.

A couple of really great articles from the archives of the New York Times‘ sports magazine Play…

“That which does not kill me makes me stronger” by Daniel Coyle is, at first glance, a profile of Jure Robic, an ultra-endurance athlete from Slovenia. Robic’s athletic accomplishments are incredible — he is a two-time winner of the Race Across America (RAAM) and the world record holder in the 24 hour time trial. But the article is most interesting and gripping as a rich exploration of the relationship between pain and emotion, providing insight into the (disturbed) mind of a champion athlete.

“Thank God, this will only get worse” is Stuart Stevens’ first-person narrative of how he discovered and fell in love with endurance sports, and provides an opportunity for him to ruminate about some of the triumphs and tragedies that he has experienced as an endurance athlete.

Friday is turning into excerpt-from-Gina-Kolata day. Her Personal Best column in the New York Times consistently produces some of the most thoughtful, interesting, and well-written articles on exercise, health, and fitness. This week’s piece explores the sport of triathlon, generally, and the difficulty of excelling at multiple disciplines — swimming, cycling, running — specifically.

Excerpts and notes from “For Peak Performance, 3 Is Not Better Than 1“, which looks to answer the question, “Is it possible to peak in more than one sport at once?”:

In the article we meet Joel Friel, a triathlon coach and author of 10 books, including the bible of the multi-sport world — literally. I did not feel comfortable calling myself a triathlete, even as an accomplished athlete in the sport, until reading and underlining what turned out to be nearly ever-other-sentence in Friel’s best-selling training guide, The Triathlete’s Training Bible.

Friel says many of his athletes sometimes feel frustrated that they aren’t running as fast as they think they can and should. His advice? “[I talk with them and ask] do you really want to be a triathlete? If you want to run faster you have to give up swimming and cycling.”

There’s a reason it’s hard to excel in three sports at once, physiologists say. The training necessary to do your best in one sport is likely to counteract what is needed to be good at another.

When you are training, said Gary Krahenbuhl, an exercise physiologist and emeritus professor at Arizona State University, improvement depends on physical and biochemical changes in muscle cells and in nerve-firing patterns. And those changes are very sport-specific, he added. The result, Dr. Krahenbuhl said, is that “changes that facilitate performance for one event may actually undermine performance in another event.

“To think that you could train in such a way as to have your greatest performance in all the sports is impossible,” he added.

Even body musculature can trip up triathletes. Swimmers need large muscles in their backs and shoulders. Runners and cyclists want small, light upper bodies. Cyclists need large quadriceps muscles. Runners don’t, and in fact they don’t want any extra muscle weight on their legs.

A woman named Anne Gordon is profiled in the article. She’s a “51-year-old triathlete [who] has never gotten a personal record in each leg of a triathlon on the same day.”

But, she said, that is part of what draws her to triathlons.

“What I love best about this sport is the training, the sense that the goal of hitting a perfect 10 for all three sports will take a lifetime.” And that, she added, “is O.K. by me.”

As noted, I participated in the sport of triathlon for a few years before leaving for a host of issues that I’ll explain in another post. But the elusiveness of perfection that Ms. Gordon refers… This is what intrigued me about triathlon. There are so many variables in a race — the swim, bike, and run, of course, but also the transitions, hydration and nutrition management, and gear and technical issues — that I never executed anything close to a perfect performance.

But it is that frustration — I had a great swim and run, but I got two flats on the bike section, or I didn’t grab my special-needs bag out of T2 and utterly bonked on the run — and that hope — Next time, baby. Next time – that kept me racing. I couldn’t quit until I mastered the sport and conquered at least one race.

It’s an ultimately futile chase for perfection, I realized. But an exciting and inspiring one. Says Ms. Gordon:

“The simple act of working hard at three things requires a diversity and balance in my life that is rewarding in and of itself. It is good for my spirit to know that I have to work hard and be patient to achieve mastery.”

I just arrived in Boston to run the 112th Boston Marathon on Monday, the most historic and famous footrace in the world. With the marathon just a few days around the corner, it seems an appropriate occasion to revisit the opportunity to enlist the Public Broadcasting Service (PBS) as your new marathon coach…

Last year, PBS’ NOVA documentary series aired a fascinating program, aptly titled Marathon Challenge, that “explores what it takes, physically and mentally, for novice runners to make it through a classic test of endurance [a marathon].”

And not just any marathon. Thirteen newbie runners were put through a nine-month regimen designed to prepare them for the 2007 Boston Marathon, the granddaddy of all road races.

Created in cooperation with the Boston Athletic Association, which granted NOVA unprecedented access during the 111th Boston Marathon (April 16, 2007), and Tufts University, the film takes viewers on a unique adventure inside the human body, tracking changes in the runners’ bodies.

NOVA is the highest rated science series on television and the most watched documentary series on public television. It is also one of television’s most acclaimed series, having won every major television award, most of them many times over.

The series originally aired last year, but is sometimes re-aired on your local PBS affiliate. If you can’t catch it on the boob-tube, you can watch NOVA’s Marathon online.
