  • Injuries Involving Off-Road Cycling
    o RIGINAL RESEARCH_______________________________ Injuries Involving Off-road Cycling Frederick P. Rivara, MD, MPH; Diane C. Thompson, MS; Robert S. Thompson, MD; and Viviana Rebolledo Seattle, Washington BACKGROUND. Data on injuries due to off-road bicycling are scarce, but do indicate that injuries in this sport are frequent. We examined the pattern of injuries to off-road riders as part of a larger study of bicycle injuries and helmet use. METHODS. We undertook a prospective study of bicycle-related injuries identified at seven emergency depart­ ments in Seattle, Washington, between March 1992 and August 1994. Hospitalized patients and medical examin­ ers’ cases were included. Detailed questionnaires and abstraction of all medical records provided information on crash and rider characteristics and injury type and severity. RESULTS. A total of 3390 injured riders participated, representing an 88% response rate. Of all injured cyclists, 127 (3.7%) were injured riding “off road.” Seventy-three percent of off-road cyclists were 20 to 39 years of age, and 86.6% were male. Helmet use was 80.3% for off-road cyclists as compared with 49.5% for other cyclists. The number of head and face injuries for the off-road cyclists was only 40% of the number incurred by other cyclists. Four percent of off-road cyclists had severe injuries (Injury Severity Score >8), and 6.3% were hospital­ ized, compared with 6.8% and 9.4%, respectively, of other cyclists. CONCLUSIONS. The majority of off-road bicycling injuries are minor. Off-road cyclists are less likely to have head and face injuries than other cyclists and are more likely to wear helmets.

    Natasha Snyder [email protected] Beginning Mountain Bike Racing in the TriCities TN/VA: Sweat and Gear without Fear Natasha Snyder <[email protected]> Author Natasha Snyder and her beloved racing steed on a 35 mile training ride. Alvarado Station Store, Creeper Trail, Abingdon, VA. Natasha is a retired mountain bike racer from Bristol TN who specialized in cross country and cyclocross, with several trophy finishes. Natasha Snyder [email protected] The world of mountain bike racing is exciting, exhausting, varied—and accessible. If you are a competent mountain biking enthusiast who has mastered basic riding skills and built a decent level of fitness, you may be ready to explore the next step: the local racing circuit. With some readily available equipment and determination, you could begin collecting trophies in no time. Most adults who purchase a mountain bikes are simply recreational riders, looking to enjoy a comfortable, ecologically-sound, human-powered ride around their neighborhood or perhaps a quick ride to the beach during vacations. After all, mountain bikes are stylistically diverse, slower and safer than motorcycles, and more comfortable than skinny road bicycles. However, sometimes a casual rider becomes a true “enthusiast,” which is what people involved in bicycle racing call those who are more than recreational riders, but not quite elite athletes. Once the desire to go fast surpasses the desire to arrive home clean and comfortable, the time may have arrived for you to consider preparing to enter a local or amateur mountain bike race here in the Tri Cities and surrounding region.
