To evaluate the effectiveness of a trainer-supervised judo-specific injury prevention warm-up programme on overall injury prevalence.
We conducted a two-arm, cluster randomised controlled trial; the Injury Prevention and Performance Optimization Netherlands (IPPON) study. Judo athletes aged≥12 years were randomised by judo school to IPPON intervention or control group who performed their usual warm-up. Primary outcome was overall injury prevalence (%) over the follow-up period (16-26 weeks) measured fortnightly with the Oslo Sports and Trauma Research Centre Questionnaire. A modified intention-to-treat analysis was performed due to COVID-19, with estimates for the primary outcome obtained using generalised linear mixed models. Secondary outcomes included: prevalence of severe injuries, overall incidence, time-loss injuries, exposure, adherence and experiences of trainers and athletes.
269 judo athletes (IPPON: 117, Control: 152) were included. Mean injury prevalence over 16-26 weeks was 23% (95% CI 20% to 26%) in the IPPON and 28% (95% CI 25% to 30%) in the control group. We observed no significant difference of all reported injuries (OR 0.72 in favour of the IPPON group; 95% CI 0.37 to 1.39). Secondary outcomes also demonstrated no significant differences between groups. Specifically, no significant difference of severe injuries was reported (OR 0.80 in favour of the IPPON group; 95% CI 0.36 to 1.78). All trainers and 70% of athletes perceived the IPPON intervention as successful.
The IPPON intervention did not significantly reduce the overall and severe injury prevalence. Despite this, we suggest the IPPON intervention be considered as an useful alternative to regular judo warm-up, given the high adherence and the positive clinical experiences of trainers and athletes.

评估由教练监督的柔道专项损伤预防热身计划对总体损伤发生率的有效性。
我们进行了一项双臂、整群随机对照试验；即荷兰损伤预防与性能优化（IPPON）研究。年龄≥12岁的柔道运动员按柔道学校随机分为IPPON干预组或对照组，对照组进行常规热身。主要结局是随访期（16 - 26周）内的总体损伤发生率（%），每两周使用奥斯陆体育与创伤研究中心问卷进行测量。由于新冠疫情，进行了改良的意向性分析，主要结局的估计值通过广义线性混合模型获得。次要结局包括：重伤发生率、总体发病率、失能损伤、暴露情况、依从性以及教练和运动员的体验。
纳入了269名柔道运动员（IPPON组：117名，对照组：152名）。在IPPON组中，16 - 26周的平均损伤发生率为23%（95%可信区间20%至26%），对照组为28%（95%可信区间25%至30%）。我们观察到所有报告的损伤无显著差异（优势比为0.72，支持IPPON组；95%可信区间0.37至1.39）。次要结局在两组之间也无显著差异。具体而言，未报告重伤有显著差异（优势比为0.80，支持IPPON组；95%可信区间0.36至1.78）。所有教练和70%的运动员认为IPPON干预是成功的。
IPPON干预并未显著降低总体和重伤的发生率。尽管如此，鉴于高依从性以及教练和运动员的积极临床体验，我们建议将IPPON干预视为常规柔道热身的一种有用替代方案。
