Will biking hurt my bones?

Is Bicycling Bad for Your Bones?
This title made me pause. I am using the exercise bike 5-6 hours each week.
Reading the article reassured me.
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 thatal most 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.
Another recent study, this one published last year, had similar results. It followed competitive cyclists over the course of a race season in Colorado. The riders, aged 27 to 44, began with slightly below-average bone density. By the conclusion of the race season, they had lost a significant portion of their total, already-low bone mass in their hips, though not in their spines. At a three-month follow-up exam, however, they showed a small amount of bone recovery in the hips.
Ah, but these are competitive cyclists who spend hours each day on the bike.
Even more encouraging, most recreational cyclists probably don’t need to worry too much about their bones. “The studies to date have looked primarily at racers,” Smathers says. “That’s a very specialized demographic. These guys train for hours at a very high intensity. They sweat a lot. They never go for runs. They don’t usually do much weight-lifting,” to avoid adding bulk. “They’re strange.” He knows. “For competitive riders, I’d recommend spending some time weight-training.” If you do race or train hard and often on a bike, consider a bone scan, he says. “It’s good to know your status.” For himself, his racing career ended with hip surgery and four metal pins in the joint after his second severe crash. “I do miss racing,” he says. On the plus side, his latest bone scan, completed just weeks ago, shows that his bone density, while still low, is increasing.
Not to worry.

To understand the bone density problem we may have to rethink the current paradigm. The paradigm I currently align my thinking with is the one supported by the author of the book, the PH Miracle, Dr. Robert Young. http://en.wikipedia.org/wiki/Robert_Young_(author) Dr Young sees obesity as a symptom of imbalance in bodily Ph. In his book Young states that when the body has excess acids it balances this ph imbalance by storing these excess acids in the form of Fatty Acids in adipose tissue. Blood ph is programed to maintain a slightly Alkaline Ph of 7.365. Here is what I believe: What this means is that our bodies are intelligently designed to balance on one side of the perfect ph, 7, and maintains this very delicate blood ph balance 7 days/week 365 days a year, no accident! Our bodily impulses on the other hand cause us to crave things like beer-ph4, soda pop-ph2.8. Most things sweet will cause us to accumulate acids in the body. Now as I stated in one of my other blog comments, Lactic Acid has a ph of 2.5 which is even more acidic than most of the foods we are lead to eat by our impulses for things that make us feel good. Through my research I found information leading me to understand that Calcium is the most alkalizing element found in the body. Humm, now lets connect the dots. When the body has STRONG acids present and needs to rid them from the body it will find an organic mineral(calcium) and combine this mineral with the STRONG acid. This turns the STRONG acid into a harmless salt. Why do we taste salty when we sweat? What kind of athletes spend hours and hours on a bike sweating? What kind of athletes do not typically do impact exercises that would stimulate the body to upgrade bone density? This is why I use vibration technology in my training. One of the exciting unexpected results from vibration training on vib plates was an increase in bone density as well the primary benefit of an increase in metabolism and oxygen uptake.

Joe, here’s a comment. We’re obese because we eat too much, and we’re lazy as a society. Stop trying to make elegant answers to a simple question.

The most talked about in the form of movement in the afternoon, vibration training, the training, which may be the loss of weight and his body burns 174 calories in 5 minutes. But there is much more to this celebrity fitness program

Cycling, unlike running or weight-lifting, causes little impact to skeletons. Bones react to external stresses by strengthening bone. Smathers and other researchers aren’t sure why cyclists have lower bone density.
