Oh No! Now it's bad for my bones!!

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Oh No! Now it's bad for my bones!!

http://ideas.theatlantic.com/2009/07...o_the_bone.php

Is cycling bad for the bones? A number of intriguing studies published in the past 18 months, including Smathers', have raised that possibility -- an issue that has special resonance now, with this weekend's start of the 2009 Tour de France. Certainly, the toll of broken bones among top-level racers is high. Famously, Lance Armstrong broke his collarbone this year, while Christian Vande Velde, another of America's premier Tour hopes, fractured six bones, including three in his spine, during a crash at the Giro d'Italia in May.
Of course, slamming into the pavement at 40 miles per hour can be expected to break anyone's bones. But Smathers' research suggests that other factors may be at work as well. "If you have low bone mineral mass, you can wind up with a much more serious break from a crash" than if your bones are thicker, he points out.
In his study, the bone density of 32 male, competitive bike riders, most in their late 20s and early 30s, was compared to that of age-matched controls, men who were active but not competitive athletes. Bone scans showed that almost all of the cyclists had significantly less bone density in the spine than the control group. Some of the racers, young men in their 20s, had osteopenia in their spines, a medical condition only one step below full-blown osteoporosis. "To find guys in their twenties with osteopenia was surprising and pretty disturbing," Smathers says.

As I recall, the book "Bike for Life" includes a chapter on this topic. It was published in 2005. I believe it's also addressed in "Younger Next" which is a couple years old, too.

It's a fact: bike riding is not a weight-bearing exercise. Weight bearing exercise is one of the best things you do for your bones.

And yes, there are thread(s) already going on this topic.

Being lazy is also bad for you. Some people find all other activities boring.

Doesn't surprise me a bit. There's nothing magical about a bike, and if you constantly do one thing and one thing only for exercise, you're more likely to suffer whatever sport-specific problem that involves. It's a machine designed by people, nothing more. Use it all the time and you're bound to have some problem related to it.

Sure you have to weigh it against heart disease, diabetes, hypertension, etc., but really, there's no rule that says you can't mix it up a bit and go for a run or walk every now and then...

Hike, backpack, hit the gym. I suspect one little old cal/mag tablet teice a day would
prevent most of this.

But....cycling doesn't strenghten everything, and some exercises are good for cycling, even if it's only preventitive like core exercises.

One hour a week for legs and back, another hour once a week for arms and core.
Problem solved.

No--"one little cal/mag tablet twice a day" won't do it. Weight bearing exercise will.
