The Combined FIFA 11+ and Change of Direction Training

The study has investigated the effects of adding change of direction (COD) training to the FIFA 11+ on lower extremity performance in soccer players. The investigators are interested in knee valgus angle during cutting which is typically suggested as a critical risk of anterior cruciate ligament injury. Peak knee valgus angle during cutting is expected to reduce immediately after adding COD training to the FIFA 11+.

Treatment and study plan

Change of direction training

Behavioral

The experimental group is implemented FIFA 11+ program combined with COD training

FIFA 11+ program

Behavioral

The experimental group is implemented FIFA 11+ program.

Primary outcomes

Peak knee valgus angle

Time frame: At pre-training and immediate post-training of prevention program

Knee valgus angle during cutting tests will be assessed before and after training for both groups. Two-dimensional analysis will be used to capture cutting movement and knee valgus angle will be extracted in the free software analysis.
