The Bicycling Paradox: Fit Doesn’t Have to Mean Thin

Here’s an article by a New York Times writer which should make all of us less-than-svelte cyclists happy!

Andy Hampsten, the former pro cyclist, the only American ever to win the Tour of Italy, the first American ever to win the grueling Alpe d’Huez stage of the Tour de France, does his best to discourage casual riders from signing up for the cycling trips he leads in Tuscany.

“All of our trips are designed to satisfy experienced riders,” Mr. Hampsten writes on his Web site. To train, he suggests, “you should ride at least 100 miles a week for at least 6 to 10 weeks” on routes with “as many hills as you can find.”

So I had an image of what our fellow cyclists would look like when my husband, son and I arrived in Castagneto Carducci for a cycling vacation. They would look like Mr. Hampsten, who at age 45 remains boyishly thin and agile, bouncing with energy.

I was wrong. For the most part, our group consisted of ordinary-looking, mostly middle-age men and a few middle-age women.

These were serious cyclists. One of them was Bob Eastaugh, a 63-year-old justice on the Alaska Supreme Court who said he rode mostly to stay in shape for his true passion, downhill ski racing.

And our trip was challenging. The longest hill was 15 miles, the steepest had a 15 percent grade, the longest one-day ride was 90 miles, and the terrain was never, ever flat. It is hard to imagine that a group of middle-age adults could have handled an equivalently difficult 10 days of running. What, I wondered, made bicycling different?

It turns out that others, too, have been struck by the paradox of bicycling fitness.

“When I first got into cycling, I would see cyclists and say, ‘O.K., that’s not what I perceive a cyclist to be,’ ” said Michael Berry, an exercise physiologist at Wake Forest University. Dr. Berry had been a competitive runner, and he thought good cyclists would look like good runners — rail-thin and young.

But, Dr. Berry added, “I quickly learned that when I was riding with someone with a 36-inch waist, I could be looking at the back of their waist when they rode away from me.”

He came to realize, he said, that cycling is a lot more forgiving of body type and age than running. The best cyclists going up hills are those with the best weight-to-strength ratio, which generally means being thin and strong. But heavier cyclists go faster downhill. And being light does not help much on flat roads.

James Hagberg, a kinesiology professor at the University of Maryland, explains that the difference between running on a flat road and cycling on a flat road has to do with the movement of the athlete’s center of gravity.

“In running, when you see someone who is obviously overweight, they will be in trouble,” Dr. Hagberg said. “The more you weigh, the more the center of gravity moves and the more energy it costs. But in cycling, there are different aerodynamics — your center of gravity is not moving up and down.”

The difference between cycling and running is like the difference between moving forward on a pogo stick and rolling along on wheels. And that is why Robert Fitts, an exercise physiologist at Marquette University who was a competitive runner, once said good runners run so smoothly they can almost balance an apple on their heads.

Even Mr. Hampsten has been surprised by the cycling paradox. He recalls a woman from San Diego who went on one of his trips. “She was quite overweight,” he said, and even though she claimed to be an experienced cyclist, he worried that she would have trouble keeping up with the group. He was wrong.

“She rode so well,” Mr. Hampsten said. “Her cadence was very efficient. I was just amazed and delighted.”

As for the effects of aging, serious recreational cyclists do slow down, but they are not penalized as much as runners by the passing of years, Dr. Hagberg said. It’s because cycling, while grueling, is not as demanding as running.

“The best example of that, in a bizarre way, is the Tour de France,” Dr. Hagberg said. “What runner could go out six hours a day for three weeks and not be totally trashed after a day or two? That’s a microcosm of the aging issue.”

Still, even the best serious recreational cyclist is almost a different species from a professional rider. How much faster, our touring group asked Mr. Hampsten, would a professional rider go up that 15 percent grade during a race? About twice as fast as the fastest in our group, he replied.

And how about recovery after racing? Mr. Hampsten used to compete in 100 races a year, including the Tour de France, and he would recover by going for a long, relaxed ride. It sometimes took him three hours of cycling to warm up after a hard race. Then he’d continue for another two hours.

But recovery does become a limiting factor for professional cyclists, Mr. Hampsten said. It’s why most professional riders can no longer win long, multiday races after age 32.

“It’s almost eerie that at 32 years, you stop winning,” Mr. Hampsten said. “The endurance seems to stay, but recuperation doesn’t come around.”

When Mr. Hampsten retired, he was 34, “and I hadn’t won a race in two years.”

Now, he estimates, he is 80 percent as fit as he used to be.

But 80 percent for Andy Hampsten is still impressive. As soon as our cycling tour ended, he headed out on a fast ride that included a long hill to the town of Suvereto, taking a road with 187 switchback turns.

“It is my favorite road to ride,” he said.

Pumping Iron

Being a female athlete has its positives and negatives (mostly positives).  With regard to iron deficiency, it can be a double whammy since, as a pre-menopausal woman, you lose blood (and thus iron) every month, and as an athlete, you may have an increased need for iron.  Hard training speeds up red blood cell production and thus the need for iron in those cells.  You also lose iron through sweat.  Those who don’t eat red meat are even more at risk for iron deficiency which is the most common nutritional deficiency in the US particularly among children and women up to age 50. 

What does iron do for your body?  It helps get oxygen to your muscles.  Without it, the red blood cells can’t grab onto oxygen and distribute it throughout your body.  With less oxygen going to your muscles and brain, your performance suffers.  Your brain will be deprived as well so you find it hard to concentrate and feel tired.  Cells which fight infection are also dependent upon iron.  In addition iron is also used in chemical reactions that help fuel your body.

Sports anemia is often used to describe a low-iron state.  Symptoms include a reduced desire to train, increased heart rate, decreased oxygen consumption, fatigue and increased blood lactic acid (so recovery slows).  You may also have a poor appetite and be more susceptible to colds and infections.  You may get injured more often.  Fingernails may become thin, brittle, and white. 

What else does this sounds like?  Overtraining!  How do you know the difference?  You don’t.  Your doctor will, however, through a blood test.  How do you treat the problem?  Increasing your dietary iron intake will suffice unless your deficiency is severe.  Again, only your doctor will be able to tell you whether you need iron supplements.  Just as too little of something is bad, too much can be just as bad if not worse.  You may put yourself at a higher risk of cancer and heart disease.  And, unless an athlete is iron deficient, supplementation will not improve performance.

RDA recommendations for women and teens is 15 mg per day.  Endurance athletes should shoot for a little more at about 18 mg per day. 

What foods are rich in iron?  Foods from animals such as red meat, liver, and poultry and fish are better absorbed than foods from plants such as fruits, vegetables, dried beans, nuts and grains.  Most grain foods such as cereals, pasta, rice and bread are fortified with heme iron, the type of iron from animals, and make a good alternative to meats and fish. 

Cooking in a cast iron skillet or pot can increase the level of iron in food by as much as 20 times, although this type of iron may not be well absorbed.  Acidic foods such as chili and spaghetti sauce are especially good at leaching out the iron from cooking pots.  The longer the food cooks in the pot, the more iron is absorbed. 

Pairing food consumption with Vitamin C-rich foods also increases absorption.   Skip the caffeine with your next meal, however, as it reduces iron absorption.

How to Keep Your Cycling Spirit Alive or Mojo Magic for the Bike

You got that shiny new bike a couple of months ago when the bike store had a sale. Your neighbor sold you his hand-me-down bike when he left town taking only a suitcase with him. Your husband bought you a bike so you could ride with him, but he and all his hammerhead friends drop you like a bad habit every ride.

What’s a girl to do?

Usually, when the going gets tough, the tough get a pedicure. In this case, however, the tough start thinking smart and taking action.

Here’s how to keep your cycling spirit alive by getting you off your duff, in your saddle, and out the door.

Socialize

If some of your friends cycle, get them to commit to riding with you once or twice a week. Promise them chocolate as a reward until the habit sticks. Your friends don’t ride? Find new ones! There are a zillion ride choices in the greater Orlando area. Check the BOBbies discussion board for ride opportunities. Visit bike shops and ask them for information about rides. Join Hal’s ride email list and receive weekly updates about almost every single ride in town. Become a BOBbie, a Freewheeler, a Seminole Cyclist, a Windermere Roadie or all of the above!

Improvise

Is your schedule crazy and you don’t have much time to ride outdoors? Mix spinning with cycling to get a similar workout. Buy a high-quality headlight for the front of your bike if you need to ride in the dark, either early in the morning or in the evening. Don’t forget the red light for the back too. Find looping routes close to home and ride them for time and distance, not scenery.

Prioritize

Make cycling as important as almost anything else you do during your busy day. If it’s the first thing you do out of bed or what you look forward to after work, include it in your daily plans. Set aside an hour for you and your bike every day or every other day. Pretty soon, you’ll look forward to your ride and feel bad about missing it.

Glamorize

Buy yourself some cool cycling jerseys and good-quality shorts. Get some matching socks. Make a fashion statement so you’ll be steppin’ out in style when you get on the bike. Remember, it doesn’t matter how you ride as long as you look good doing it!

Strategize

Find specific goals to strive for. Charity rides are a terrific way to motivate yourself, meet other like-minded cyclists, and promote a worthy cause. Celebrate your health. How about a century ride? Find one in your area and start training to finish it. Maybe you want to become a triathlete. Check out the course of an upcoming race and ride it until you’ve conquered it. For a real challenge, sign up for a multi-day bike tour such as RAGBRAI or BRAG.

Finalize

Nothing keeps you committed like telling others you’ll meet them for a ride. Make sure others know you’ll arrive (on time) and be ready to ride. Then fill your water bottles and stick ‘em in the fridge ahead of time so you just have to pull them out and put them on your bike when it’s time to go. Lay out your clothes the night before a morning ride or pack your bag the night before so you can grab and go if you’ll need to change before riding after work. It’s harder to say no to yourself if everything is ready.

Now tell us what you do to stay motivated!
