Researchers are evaluating the added value of support interventions to improve the use and injury prevention effectiveness of the Knee Control+ exercise program in male and female youth and adult amateur football teams. This type 3 hybrid cluster randomized controlled trial primarily focuses on how well the implementation support helps teams use the program, with injury prevention as a secondary outcome. The study also explores coach confidence, player motivation, training dosage, and factors affecting program use and adherence. Teams will be randomized before the 2025 season to either an intervention group receiving additional support or a control group with standard access to the digital Knee Control+ materials from the Swedish Football Association. The intervention includes workshops, site visits by fitness coaches, digital materials, leaflets, and social media support to help coaches implement the program. The control group will access the same digital materials and a digital workshop introduction without extra support. Participants, including coaches and players, will provide weekly and monthly data throughout the 7-month competitive season from April to October 2025 via web-based questionnaires. Researchers will monitor program use, behavioral outcomes like self-efficacy and motivation, injury incidence, and adherence to the exercise program. A sub-study will include qualitative interviews with coaches and club representatives. The total study period covers pre-season, competitive season, and follow-up assessments after the season ends in November 2025.
