Purpose. The occurrence of low back pain (LBP) in marathon runners has been poorly understood. This study aimed to describe the risk factors and identify whether these factors can cause LBP in these athletes. Methods. A self-developed questionnaire was randomly distributed to 850 runners of running a half or a full marathon. Participants responded with the questionnaire focusing on previous training and running conditions after their competitions. Results. On the basis of the remaining 800 valid questionnaires, the incidence of LBP was 4.50% (n = 36). A total of 572 (71.5%) males and 228 (28.5%) females, with an average age range of 33.9 ± 9.0 years, came from different occupations with different physical activity characteristics. However, no significant associations between occupation and runners with LBP () were found. In the final models, risk factors, including warm-up activities (, OR = 2.617), fatigue (p = 0.008, OR = 2.680), running gait posture (, OR = 2.273), and environmental temperature (, OR = 6.584), were significantly associated with LBP in marathoners. Conclusion. Although LBP was uncommon in marathoners, it was linked to the factors such as insufficient warm-up activities, fatigue, poor running gait posture, and uncomfortable environmental temperature. Future studies need to validate these results. Nevertheless, these findings could still be useful for protecting the lower back area of runners clinically.

马拉松运动员下腰痛的发生率和危险因素

目的。人们对马拉松运动员下腰痛（LBP）的发生了解甚少。这项研究旨在描述危险因素，并确定这些因素是否会导致这些运动员的LBP。方法。自行编制的调查问卷被随机分发给850名参加半程或全程马拉松的跑步者。参赛者以问卷调查表作为回应，问卷调查表着重于比赛后的先前训练和跑步状况。结果。在剩余的800张有效问卷的基础上，LBP的发生率为4.50％（n = 36）。共有572名（71.5％）男性和228名（28.5％）女性，平均年龄范围为33.9±9.0岁，来自不同职业，具有不同的体育活动特征。但是，职业和跑步者与LBP之间没有显着的关联（）被发现。在最终模型中，风险因素包括热身活动（， OR = 2.617），疲劳（ p  = 0.008，OR = 2.680），步态姿势（， OR = 2.273）和环境温度（（ OR = 6.584）与马拉松运动员的LBP显着相关。结论。尽管LBP在马拉松运动员中并不常见，但它与诸如热身活动不足，疲劳，步态姿势不良和环境温度不舒适等因素有关。未来的研究需要验证这些结果。尽管如此，这些发现仍可在临床上保护跑步者的下背部。
