Mountain Biking Injury Report

Keep in mind the authors were very careful at the end of the article (not published in a peer review journal mind you - but informative notheless) to note, do not extrapolate these results to other groups of cylclist. So of course that's exactly what Vandeman does! They are not sure how consistent these results will compare with the public at large. This was a survey of a racing club in San Diego that mostly raced on the road. Actually, the vast majority of their riding will be training on the road. Road racers will put in several miles of training for every mile of racing. Keep in mind, these are experienced road riders and they know how to ride to minimize their risks; less-experienced road riders will likely have far higher injury rates and deaths per mile. We had three in one week last summer in Portland. We've never had a mountain biking death AFAIK. The good thing about mountain biking is that "Most crashes result in only minor injuries such as abrasions, contusions, and lacerations" (http://www.physsportsmed.com/issues/...r/kronisch.htm). "The incidence of injuries in mountain biking is comparable to that in other outdoor sports, the majority of injuries being minor." (http://webdb.iu.edu/Hperweb/iole/ind...details&Id=171) Note that the last study was a survey of 3474 mountain bikers - far more relevant that Vandeman's extrapolation of a study of 81 road riders. That's why this real science matches reality, and Vandeman's junk science doesn't. -- -BB- To reply to me, drop the attitude (from my e-mail address, at least) |

You are neither a scientist nor did your parents inpart much common sense on you or it failed to stick. So, studies that do not agree with your opinion are biased. Other studies that you cherry-pick bits from to support your opinion, you claim are totally supportive of your position, even though an objective reading might suggest otherwise. Your opinion does not define truth outside your own mind. Happy trails, Gary (net.yogi.bear) ------------------------------------------------ at the 51st percentile of ursine intelligence Gary D.

I do not need a scientific study when the observable facts are almost no deaths a year compared to hundreds. Provide one study which documents mt. bike deaths being 1/100th of road cyclist deaths. The burden is on you. Because the observable facts (extreme rarity of mt. bike deaths world wide) fail to support your case.

I never asserted that, liar. Then if you never asserted that (go back and check my post, it all had to do with comparing the DEATH RATE of road and mt. bike) your arguments have all been rather stupid. So you can claim I'm a liar, but a review of your posts will show that I never debated the point of injury and always focused my debate on the variable death rate. Yet you continued to argue with me anyway, so you were either sloppy in your reading, or sloppy in your argument or you were simply lying all along. Your original assertion was that choosing mt. biking over road riding because road riding was more dangerous was invalidated due to this San Diego Survey you quoted. I correctly pointed out, that most individuals who are risk averse (as my wife) base their decision of risk on death rate not injury rate. While mt. bikers may become injured more often (a point I am not debating, as I suspect that a nationwide survey would support such a hypothesis), they die less often, because of the lack of cars, the single greatest factor that contributes to the death of cyclist. The study you cited, supports that contention. Thus, while you mistakenly focused on injury, most people that choose a riding style based on risk, due so based on the variable death rate. This whole argument I suspect is silly anyway, while risk aversion may be a significant component for some people (as my wife), my speculation is that risk aversion plays a minor role in most peoples decisions regarding the type of riding they choose to do. === I am working on creating wildlife habitat that is off-limits to humans ("pure habitat").
