Description
Background: The FIFA 11+ was developed as a complete warm-up program to prevent injuries in soccer players. Although reduced hip adduction strength is associated with groin injuries, none of the exercises included in the FIFA 11+ seem to specifically target hip adduction strength.
Purpose: To investigate the effect on eccentric hip adduction strength of the FIFA 11+ warm-up program with or without the Copenhagen Adduction exercise.
Study Design: Randomized Controlled Clinical Trial.
Methods: We recruited 45 eligible players from two U19 elite male soccer teams. Players were randomized into two groups; one group carried out the standard FIFA 11+ program, while the other carried out the FIFA 11+, but replaced the Nordic Hamstring exercise with the Copenhagen Adduction exercise. Both groups performed the intervention three times weekly for 8 weeks. Players completed eccentric strength and sprint testing before and after the intervention. Per-protocol analyses were performed, with 12 players excluded due to low compliance (<67% of sessions completed).
Main Outcome: Eccentric hip adduction strength (Nm/kg).
Results: Between-group analyses showed that there was a significant greater increase in eccentric hip adduction strength of 0.29 Nm/kg (8.9%, p=0.01) in favor of the group performing the Copenhagen Adduction exercise, while there was no within-group change in the group that used the standard FIFA 11+ program (-0.02 Nm/kg (-0.7%), p=0.69).
Conclusion: Including the Copenhagen Adduction exercise in the FIFA 11+ program increases eccentric hip adduction strength, while the standard FIFA 11+ program does not.
