INTRODUCTION Plantar fasciitis (PF) is one of the most common running-related injuries. PURPOSE The aim of this prospective study was to determine the incidence of PF and identify potential risk or protective factors for PF in runners and non-runners. METHODS Data from 1206 participants from the 4HAIE cohort study (563 females/643 males; 715 runners/491 non-runners; 18-65 years of age) were included in the analysis. We collected biomechanical data during overground running using a 3-D motion capture system at the baseline and running distance data via retrospective questionnaires and followed the participants for 12 months following the baseline data collection. Participants were asked weekly about any sports-related injury (including PF). A binary logistic regression was performed to reveal potential associations between running distance and biomechanical risk factors and PF while controlling for running distance, sex, and age. RESULTS The total incidence of PF was 2.3% (28 PF from 1206 participants), 2.5% in runners and 2.0% in non-runners (P = 0.248). Runners who ran more than 40 km per week had six times higher odds of suffering PF than individuals who ran 6-20 km/week (P = 0.009). There was a significant association between maximal ankle adduction and PF, that is, runners with a lower abduction angle during the stance period had higher risk of PF (P = 0.024). No other biomechanical variables indicated significant associations with PF. CONCLUSIONS Regular running with a moderate weekly volume and more toeing out of the foot relative to the shank may reduce the risk against PF in runners which may be useful for researchers, runners, coaches, and health professionals to minimize PF injury risk.

足底筋膜炎的跑步距离和生物力学危险因素：一项为期一年的前瞻性 4HAIE 队列研究。


引言 足底筋膜炎 （PF） 是最常见的跑步相关损伤之一。目的 这项前瞻性研究的目的是确定 PF 的发生率，并确定跑步者和非跑步者 PF 的潜在风险或保护因素。方法 来自 1206 名参与者的数据来自 4HAIE 队列研究 （563 名女性/643 名男性;715 名跑步者/491 名非跑步者;18-65 岁） 被纳入分析。我们在基线时使用 3-D 动作捕捉系统收集地上跑步期间的生物力学数据，并通过回顾性问卷收集跑步距离数据，并在基线数据收集后对参与者进行了 12 个月的随访。参与者每周被询问任何与运动相关的伤害 （包括 PF）。进行二元 logistic 回归以揭示跑步距离与生物力学危险因素和 PF 之间的潜在关联，同时控制跑步距离、性别和年龄。结果 PF 的总发生率为 2.3%（来自 1206 名参与者的 28 个 PF），跑步者为 2.5%，非跑步者为 2.0% （P = 0.248）。每周跑步超过 40 公里的跑步者患 PF 的几率是每周跑步 6-20 公里的跑步者的六倍 （P = 0.009）。最大踝关节内收与 PF 之间存在显着关联，即站姿期间外展角较低的跑步者发生 PF 的风险较高 （P = 0.024）。没有其他生物力学变量表明与 PF 有显著关联。结论 定期跑步，每周适度的跑步量和相对于小腿更多的脚趾伸出可能会降低跑步者发生 PF 的风险，这可能对研究人员、跑步者、教练和卫生专业人员有用，以最大限度地降低 PF 损伤风险。
