Hip adductor muscle injuries are the most common acute groin injury in athletes. Weak hip adduction strength has shown to be a risk factor for sustaining hip adductor injuries. There are only few trials concerning groin injury prevention, involving complex programs with no significant effects. A simpler, dynamic alternative like the CA could provide an implementation advantage.
20 players from 2 under-19 sub-elite football clubs were randomly allocated to intervention and control groups. The intervention group performed a 8-week protocol of the Copenhagen Adduction exercise (CA). Players performed 2 sessions/ week containing 2-3 sets of 6-15 repetitions. Outcome measures were maximal EHAD, EHAB, lateral abdominal endurance and EHAD/ EHAB ratio. Mean differences pre-and post intervention and between groups were assessed.
