Abstract：
OBJECTIVE: This study aims to investigate the efficacy of two exercise interventions in reducing lower extremity (LE) injuries in novice recreational runners.
METHODS: Novice runners (245 female, 80 male) were randomised into hip and core (n=108), ankle and foot (n=111) or control (n=106) groups. Interventions were completed before running and included exercise programmes focusing on either (1) hip and core or (2) ankle and foot muscles. The control group performed static stretching exercises. All groups were supervised by a physiotherapist and performed the same running programme. Injuries and running exposure were registered using weekly questionnaires during the 24-week study. Primary outcome was running-related LE injury.
RESULTS: The incidence of LE injuries was lower in the hip and core group compared with the control group (HR 0.66; 95% CI 0.45 to 0.97). The average weekly prevalence of overuse injuries was 39% lower (prevalence rate ratio, PRR 0.61, 95% CI 0.39 to 0.96), and the prevalence of substantial overuse injuries was 52% lower (PRR 0.48, 95% CI 0.27 to 0.90) in the hip and core group compared with the control group. No significant difference was observed between the ankle and foot group and control group in the prevalence of overuse injuries. A higher incidence of acute injuries was observed in the ankle and foot group compared with the control group (HR 3.60, 95% CI 1.20 to 10.86).
CONCLUSIONS: A physiotherapist-guided hip and core-focused exercise programme was effective in preventing LE injuries in novice recreational runners. The ankle and foot programme did not reduce LE injuries and did not protect against acute LE injuries when compared with static stretching.

摘要：
目的：本研究旨在探讨两种运动干预措施在减少新手休闲跑步者下肢（LE）损伤方面的功效。
方法：新手跑步者（245名女性，80名男性)随机分为髋部和核心部(n=108)，足踝组(n=111)或对照组(n=106)。在跑步前完成干预措施，包括针对（1）臀部和核心或（2）脚踝和足部肌肉的运动计划。对照组进行静态伸展运动。所有组均由物理治疗师监督，并执行相同的跑步程序。在为期24周的研究中，每周使用问卷调查记录受伤和跑步暴露。主要结果是与跑步相关的LE损伤。
结果：与对照组相比，髋关节和核心组的LE损伤发生率较低（HR0.66；95％CI0.45至0.97）。过度使用伤害的平均每周患病率低39%(患病率比，PRR0.61，95%CI0.39至0.96），与对照组相比，髋关节和核心组的实质性过度使用损伤的发生率降低了52％（PRR0.48，95％CI0.27至0.90）。踝关节和足组与对照组之间的过度使用损伤发生率没有显着差异。与对照组相比，踝关节和足部组的急性损伤发生率更高（HR3.60，95％CI1.20至10.86）。
结论：由物理治疗师指导的髋部和以核心为中心的运动计划可有效预防新手休闲跑步者的LE损伤。与静态拉伸相比，脚踝和足部计划并不能减少LE损伤，也不能防止急性LE损伤。
