Summary of the results categorised by the five-step Knowledge Transfer Scheme guidelines

1. Problem statementDue to the high incidence rates in judo, there is a need for the implementation of an intervention to prevent injuries among judo athletes.
2. Evidence descriptionInjury prevention programmes were found effective in reducing injury rates in other sports. For judo, no prevention programme has yet been systematically developed and no proven effective injury prevention programme exists.
3. Knowledge Transfer GroupUnanimous consensus on the design and content of the intervention was reached:
1. Focus on the prevention of shoulder, knee and ankle injuries.
2. Trainer-based exercise programme to increase adherence.
3. Including dynamic exercises performed with a partner.
4. Choice from different exercises.
5. 10–15 min programme.
6. Exercises performed as warm-up prior to the judo training.
7. Exercises performed barefoot on the tatami*
4. Product developmentPilot study: Although all exercises were approved by experts and end-users, the programme was extended with three strength exercises.
Intervention: 36 exercises divided in the categories ‘flexibility and agility’, ‘balance and coordination’ and ‘strength and stability’. 12 exercises per category with 3 levels of difficulty. Use of 4 exercises per category and 12 exercises in total as warm-up routine.
5. EvaluationThe effectiveness and feasibility of the Injury Prevention and Performance Optimization Netherlands intervention will be evaluated in a randomised controlled trial.
