Objectives To systematically develop an injury prevention programme in judo and test its feasibility: Injury Prevention and Performance Optimization Netherlands (IPPON) intervention. Methods We used the five-step Knowledge Transfer Scheme (KTS) guidelines. In the first two steps, we described the injury problem in judo and showed possibilities to reduce the injury rates. In the third step, the Knowledge Transfer Group (KTG) translated this information into actions in judo practice. Expert meetings and practical sessions were held. In the fourth step, we developed the injury prevention programme and evaluated its feasibility in judo practice in a pilot study. As a final step, we will evaluate the injury prevention programme on its effectiveness to reduce injuries. Results In the first two steps, information collected indicated the need for reducing judo injuries due to high incidence rates. Injury prevention programmes have shown to be effective in reducing injuries in other sports. For judo, no injury prevention programme has yet been systematically developed. In the third step, the KTG reached consensus about the content: a trainer-based warm-up programme with dynamic exercises focusing on the shoulder, knee and ankle. In the fourth step, the intervention was developed. All exercises were approved in the pilot study. Based on the pilot study’s results, the IPPON intervention was extended and has become suitable for the final step. Conclusion We developed the IPPON intervention using the systematic guidance of the KTS. This trainer-based programme focuses on the prevention of shoulder, knee and ankle injuries in judo and consists of 36 exercises classified in three categories: (1) flexibility and agility, (2) balance and coordination and (3) strength and stability. The effectiveness and feasibility of the intervention on injury reduction among judo athletes will be conducted in a randomised controlled trial.

针对柔道运动员的伤害预防计划的系统开发：IPPON干预

目的系统地制定柔道伤害预防计划并测试其可行性：荷兰伤害预防和绩效优化（IPPON）干预。方法我们使用了五步知识转移计划（KTS）指南。在前两个步骤中，我们描述了柔道中的伤害问题，并展示了降低伤害率的可能性。第三步，知识转移小组（KTG）将这些信息转化为柔道练习中的动作。举行了专家会议和实践会议。在第四步中，我们制定了预防伤害计划，并通过一项试点研究评估了其在柔道实践中的可行性。最后，我们将评估伤害预防程序在减少伤害方面的有效性。结果在前两个步骤中，收集的信息表明，由于高发病率，有必要减少柔道损伤。预防伤害计划已显示在减少其他运动中的伤害方面是有效的。对于柔道来说，尚未系统地制定伤害预防程序。第三步，KTG在内容上达成了共识：基于教练的热身计划，其动态练习着重于肩膀，膝盖和脚踝。在第四步中，制定了干预措施。所有练习均在初步研究中获得批准。根据初步研究的结果，IPPON干预已扩展，并已适合最后一步。结论我们在KTS的系统指导下开发了IPPON干预措施。这个以教练为基础的计划着重于预防肩膀，柔道中的膝盖和脚踝受伤包括36个练习，分为三类：（1）柔韧性和敏捷性；（2）平衡与协调；（3）力量和稳定性。柔道运动员减少伤害的干预措施的有效性和可行性将在一项随机对照试验中进行。
