To evaluate the effectiveness of the Runfitcheck on time until the onset of a new running-related injury (RRI) among adult novice runners.
A three-arm randomised controlled trial was conducted over 7 months. Adult novice runners completed a baseline online questionnaire on their characteristics, running activity, RRIs and injury preventive behaviour. Runners were randomly allocated to one of two intervention groups or the control group (n=238). One intervention group obtained access to the Runfitcheck (n=252), an online intervention to encourage injury preventive behaviour, and was fortnightly promoted to use Runfitcheck; the other intervention group (n=251) was directed towards the Runfitcheck once. Runners were followed for 4 months, not all starting at the same time over 7 months. The main outcome measure was time to a new RRI using the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire, and was analysed with survival analysis Cox regression. Generalised estimating equations (GEE) were used to gain insight into the effectiveness of the Runfitcheck.
The time to the occurrence of the first RRI did not differ between the study groups (Wald χ=0.893). GEE analysis showed no difference in the risk of a new RRI in the group that was referred to the Runfitcheck once (OR 1.22, 95% CI 0.86 to 1.74) nor in the active approach group (OR 1.01, 95% CI 0.71 to 1.45) compared with the control group. Furthermore, the onset of the new RRIs did not change over time (OR 0.96, 95% CI 0.91 to 1.01).
The online intervention Runfitcheck was ineffective in reducing the instantaneous risk of new RRIs in adult novice runners. More research is needed to determine how injuries in novice runners can be prevented.

评估Runfitcheck对成年新手跑步者直至出现新的跑步相关损伤（RRI）的时间的有效性。
进行了一项为期7个月的三臂随机对照试验。成年新手跑步者完成了一份关于其特征、跑步活动、RRI和损伤预防行为的基线在线问卷。跑步者被随机分配到两个干预组或对照组之一（n = 238）。一个干预组可以使用Runfitcheck（n = 252），这是一种鼓励损伤预防行为的在线干预措施，每两周会被推广使用Runfitcheck；另一个干预组（n = 251）仅被引导至Runfitcheck一次。对跑步者进行了4个月的随访，并非所有人都在7个月内同时开始。主要结局指标是使用奥斯陆体育创伤研究中心过度使用损伤问卷得出的出现新RRI的时间，并采用生存分析Cox回归进行分析。使用广义估计方程（GEE）来深入了解Runfitcheck的有效性。
各研究组之间首次RRI发生的时间没有差异（Wald χ = 0.893）。GEE分析显示，与对照组相比，仅被引导至Runfitcheck一次的组（比值比1.22，95%置信区间0.86至1.74）以及积极干预组（比值比1.01，95%置信区间0.71至1.45）出现新RRI的风险没有差异。此外，新RRI的发生并没有随时间变化（比值比0.96，95%置信区间0.91至1.01）。
在线干预措施Runfitcheck在降低成年新手跑步者出现新RRI的即时风险方面无效。需要更多研究来确定如何预防新手跑步者的损伤。
