背景：尽管长跑对有氧健身有明显的好处，但长跑可能产生的有害影响仍然存在争议。与这种活动相关的重复负荷可能会导致骨关节炎的发生。下肢对线不良也会导致关节负荷异常，是关节软骨过早退变的另一个可能因素。本研究的目的是调查外部冲击负荷是否在马拉松运动员的骨骼和软骨上产生内部应力，这在MR图像上是可以证明的。参与者分别评估静态下肢对齐，使用标准radiographs.Methods：六个娱乐和两个半专业的跑步者进行磁共振（MR）成像的髋关节和膝关节前，后马拉松运行冠状T1加权和冠状STIR sequence.Results：运行前和运行后扫描未能证明骨髓水肿，骨膜应力反应，或关节积液在7个跑步者。一个病人谁经历了重建他的前交叉韧带18个月前表现出一个小积液重建膝关节前和后的race.Conclusions：我们的研究结果表明，在长跑的高冲击力是耐受性良好，随后不表现出变化的MR图像。
Background: Despite its obvious benefits regarding aerobic fitness, the possible deleterious effects of long-distance running remain controversial. The repetitive loading associated with this activity could potentially predispose to the subsequent development of osteoarthritis. Lower extremity malalignment can also result in abnormal joint loading and is another possible contributing factor for premature articular cartilage degeneration. The purpose of this study is to investigate whether external impact loading in marathon runners creates internal stresses on bone and cartilage that are demonstrable on MR images. Participants were separately assessed for static lower extremity alignment, using standard radiographs.Methods: Six recreational and two semi-professional runners underwent magnetic resonance (MR) imaging of the hip and knee before and after a marathon run using coronal T1-weighted and coronal STIR sequences.Results: The pre-run and post-run scans failed to demonstrate marrow oedema, periosteal stress reactions, or joint effusions in seven runners. One patient who underwent a reconstruction of his anterior cruciate ligament 18 months ago demonstrated a small effusion in the reconstructed knee before and after the race.Conclusions: Our results suggest that the high impact forces in long-distance running are well tolerated and subsequently do not demonstrate changes on MR images.
