Brief summary
The goal of this clinical trial is to find out if a coach-focused intervention can help prevent sudden-onset, severe knee injuries in youth and senior amateur football players. The main question it aims to answer is: Does a coach-focused intervention reduce the number of sudden-onset, severe knee injuries? Researchers will compare a coach-focused intervention, designed to help coaches to use effective injury prevention training, to usual football practice to see if the intervention can prevent sudden-onset, severe knee injuries in football players. Participants will: Either receive weekly information and motivation on effective injury prevention training or continue their usual football practice for 14 weeks. All will receive a weekly text message with a survey link to report any sudden-onset knee injuries among their players for 18 weeks.
Interventions
BEHAVIORALAhead of the Game
Evidence-based injury prevention training programs and exercises will be send weekly to participants in the intervention arm. Additionally, participants in the intervention arm will be encouraged to access a study specific online platform containing information, inspiration, pep-talks and posters on injury prevention training.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The incidence of acute severe knee injuries in players. | From baseline to end of the intervention, 14 weeks after baseline. | The difference in incidence of acute severe knee injuries (\>28 time-loss days from training and matches) per 1000 hours of player exposure in players belonging to coaches in the intervention group compared with players belonging to coaches in the control group (usual practice) throughout the intervention period. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of acute minimal knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in incidence of acute minimal knee injuries (1-3 time-loss days from training or match) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Incidence of acute mild knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in incidence of acute mild knee injuries (4-7 time-loss days from training or match) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Incidence of acute moderate knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in incidence of acute moderate knee injuries (8-28 time-loss days from training or match) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Time-loss days of acute knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in burden of all acute knee injuries (the total number of time loss days from minimal (1-3 time-loss days) to severe (\>28 time-loss days from training or match) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Incidence of acute knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in incidence of all acute knee injuries (from minimal (1-3 days lost) to severe (\>28 time-loss days from training or match)) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Time-loss days of acute mild knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in burden of acute mild knee injuries (4-7 time-loss days from training or match) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Time-loss days of acute moderate knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in burden of acute moderate knee injuries (8-28 time-loss days from training or match) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Time-loss days of acute severe knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in burden of acute and severe knee injuries (\> 28 time-loss days from training or matches) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
| Time-loss days of acute minimal knee injuries | From baseline to end of the intervention, 14 weeks after baseline. | The difference in burden of acute minimal knee injuries (1-3 time-loss days from training or match) per 1000 hours of player exposure in players belonging to coaches in the intervention group versus players belonging to coaches in the control group (usual practice) throughout the intervention period. |
