To better understand the impact of long-distance running on runners' lumbar spines by assessing changes before and after their first marathon run.
The lumbar spines of 28 asymptomatic adults (14 males, 14 females, mean age: 30 years old), who registered for their first marathon, the 2019 London Richmond Marathon, were examined 16 weeks before (time point 1) and 2 weeks after (time point 2) the marathon. Participants undertook a pre-race 16-week training programme. Magnetic resonance imaging (MRI) of high-resolution 3.0 Tesla was used at each time point. Senior musculoskeletal radiologists assessed the lower lumbar spine condition.
Out of 28 participants, 21 completed both the training and the race and 7 neither completed the training nor started the marathon but not due to spine-related issues. At time point 1, disc degeneration was detected in 17/28 (61%), most predominantly at spinal segments L4-L5 and L5-S1. No back pain/other symptoms were reported. When compared to time point 2, there was no progression in the extent of disc degeneration, including intervertebral disc (IVD) height (p = 0.234), width (p = 0.359), and intervertebral distance (p = 0.641). There was a regression in 2 out of 8 (25%) participants who had pre-marathon sacroiliac joint bone marrow oedema, and a small increase in the size of a pre-marathon subchondral cyst in one participant, all asymptomatic.
Running 500 miles over 4 months plus a marathon for the first time had no adverse effects on the lumbar spine, even when early degenerative changes were present. Additionally, there was evidence of regression of sacroiliac joint abnormalities.
通过评估首次马拉松跑前后的变化，更好地了解长跑对跑者腰椎的影响。
对 28 名无症状成年人（14 名男性，14 名女性，平均年龄：30 岁）的腰椎进行了检查，他们报名参加了 2019 年伦敦里士满马拉松赛的首次马拉松比赛。在马拉松比赛前 16 周（时间点 1）和 2 周后（时间点 2）进行了检查。参与者进行了赛前 16 周的训练计划。在每个时间点都使用了高分辨率 3.0 特斯拉的磁共振成像（MRI）。资深肌肉骨骼放射科医生评估了下腰椎的状况。
28 名参与者中有 21 名完成了训练和比赛，而 7 名既没有完成训练也没有开始马拉松比赛，但并非因脊柱相关问题所致。在时间点 1，28 例中有 17 例（61%）发现椎间盘退变，最主要发生在 L4-L5 和 L5-S1 节段。没有报告背痛/其他症状。与时间点 2 相比，椎间盘退变的程度没有进展，包括椎间盘高度（p=0.234）、宽度（p=0.359）和椎间距离（p=0.641）。8 例中有 2 例（25%）有骶髂关节骨髓水肿的患者出现了退行性变化，1 例患者的软骨下囊肿略有增大，均无症状。
在 4 个月内跑 500 英里外加首次马拉松比赛对腰椎没有不良影响，即使存在早期退行性变化。此外，骶髂关节异常有消退的证据。
