Objectives To determine and compare the health status of hip joints of individuals undertaking various lengths of long-distance running and of those who are not running. Methods Fifty-two asymptomatic volunteers underwent bilateral hip 3.0 Tesla MRI: (1) 8 inactive non-runners; (2) 28 moderately active runners (average half a marathon (21 km)/week) and (3) 16 highly active runners (≥ marathon (42 km)/week). Two musculoskeletal radiologists reported the hip MRI findings using validated scoring systems. Study participants completed a Hip disability and Osteoarthritis Outcome Score (HOOS) questionnaire to indicate their perceived hip function. Results The MRI findings show that there were no significant differences among inactive non-runners, moderately active runners and highly active runners in the amount of labral abnormalities (p=0.327), articular cartilage lesions (p=0.270), tendon abnormalities (p=0.141), ligament abnormalities (p=0.519). Bone marrow oedema was significantly more common in moderately active runners than in non-runners and highly active runners (p=0.025), while small subchondral cysts were more common in runners than in non-runners (p=0.017), but these were minor/of small size, asymptomatic and did not indicate specific exercise-related strain. Articular cartilage lesions and bone marrow oedema were not found in highly active runners. HOOS scores indicate no hip symptoms or functional problems among the three groups. Conclusion The imaging findings were not significantly different among inactive non-runners, moderately active runners and highly active runners, in most hip structures, suggesting that long-distance running may not add further damage to the hip joints. Data are available upon reasonable request. Requests for access to data from the study should be addressed to the corresponding author at [laura.horga.17@ucl.ac.uk][1]. All proposals requesting data access will need to specify how it is planned to use the data, and all proposals will need approval of the study co-investigator team before data release.

104例无症状成年人的3.0 T MRI表现：从非跑步者到超长距离跑步者

目的确定并比较进行各种长度的长距离跑步和不跑步的人的髋关节的健康状况。方法52例无症状志愿者接受双侧髋关节3.0特斯拉MRI检查：（1）8名无活动的非跑步者。（2）28位中度活跃的跑步者（平均半程马拉松（21公里）/周）和（3）16位高活跃度跑步者（≥马拉松（42公里）/周）。两位肌肉骨骼放射科医生使用经过验证的评分系统报告了髋部MRI的发现。研究参与者完成了髋关节残疾和骨关节炎结果评分（HOOS）问卷，以表明他们的髋关节功能。结果MRI结果显示，非活动性非跑步者，中度活跃的跑步者和高度活跃的跑步者之间的实验室异常数量无显着差异（p = 0.327），关节软骨病变（p = 0.270），肌腱异常（p = 0.141），韧带异常（p = 0.519）。中度活动的跑步者的骨髓水肿比非跑步者和高活动的跑步者明显更常见（p = 0.025），跑步者的软骨下小囊肿比非跑步者更常见（p = 0.017），但这些是次要的体积小，无症状且未显示与运动有关的特定劳损。在活跃的跑步者中未发现关节软骨病变和骨髓水肿。HOOS评分表明三组之间均未出现髋部症状或功能问题。结论在大多数髋关节结构中，非活动非跑步者，中度活跃的跑步者和高度活跃的跑步者的影像学发现无明显差异。这表明长距离跑步可能不会进一步增加髋关节的损伤。可根据合理要求提供数据。从研究中获取数据的请求应通过[laura.horga.17@ucl.ac.uk] [1]发送给相应的作者。所有要求访问数据的提案都需要指定计划如何使用数据的方式，并且所有提案都需要在数据发布之前获得研究合作研究小组的批准。[1]：http：//laura.horga.17@ucl.ac.uk
