To determine the frequency of injuries requiring medical attention among mountain bike racers at endurance races (6 hours or greater in duration) versus traditional cross country races (less than 6 hours duration) and to determine the medical support available at races.
A survey was developed to determine participants' experience level, previous injuries, and demographic information. An additional survey was completed by injured riders to determine injuries and treatment received. The number of medical providers, their level of training, and the supplies available was determined.
The endurance riders had more years of mountain biking experience, averaged more hours of riding per week, and had fewer injuries requiring medical attention in the past year than the riders in the races. Of the cross-country riders, 7.2% were injured during the race, and 4.7% of endurance racers were injured. There was no increased risk of being injured in a race over an endurance race (odds ratio 1.6, 95% CI [0.50, 2.92]). Lacerations and abrasions were the most common injuries in both events. Head injuries, eye injuries, and blisters were only reported in the endurance events. Endurance events were more likely to have medical assistance available.
There was a greater percentage of riders reporting injuries in the cross-country races. It is possible that many of the endurance racers did not report injuries, continuing to ride or taking care of their own injuries quickly. Both events tended to have similar types of injuries and, therefore, both events most likely need similar medical support.
确定耐力赛（持续时间6小时或更长）与传统越野赛（持续时间少于6小时）中需要医疗护理的山地自行车赛车手受伤的频率，并确定比赛中可获得的医疗支持。
设计了一项调查，以确定参与者的经验水平、既往受伤情况和人口统计学信息。受伤车手还完成了另一项调查，以确定受伤情况和接受的治疗。确定了医疗人员的数量、他们的培训水平以及可用的物资。
与参加越野赛的车手相比，耐力赛车手有更多年的山地自行车骑行经验，平均每周骑行时间更长，且在过去一年中需要医疗护理的受伤情况更少。在越野赛车手中，7.2%在比赛中受伤，耐力赛车手中4.7%受伤。越野赛中受伤的风险并没有高于耐力赛（优势比1.6，95%可信区间[0.50, 2.92]）。撕裂伤和擦伤是两项赛事中最常见的损伤。头部损伤、眼部损伤和水泡仅在耐力赛中被报告。耐力赛更有可能获得医疗援助。
越野赛中报告受伤的车手比例更高。可能许多耐力赛车手没有报告受伤情况，继续骑行或迅速自行处理伤口。两项赛事的损伤类型往往相似，因此，两项赛事很可能都需要类似的医疗支持。
