Overview
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+.
