The Combined FIFA 11+ and Change of Direction Training on Knee Valgus Angle During Cutting in Male Soccer Players

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+.
