Comparison of Hip Adductor Training Using an Isokinetic Device Versus the Copenhagen Adduction Exercise
Sponsor: University of Primorska
Summary
This randomized controlled trial compared two exercise approaches for strengthening the hip adductor muscles in healthy, recreationally active adults. Participants were assigned to one of three groups: training using a custom isokinetic device, training using the Copenhagen adduction exercise, or a control group that did not perform the specific hip adductor training. The intervention lasted 8 weeks. The device-based program used controlled eccentric muscle actions, in which the hip adductors produce force while being lengthened, whereas the Copenhagen adduction exercise involved a commonly used body-weight strengthening exercise. The purpose of the study was to determine how these two types of hip adductor training affect muscle strength and other physical characteristics that may be relevant to performance and the prevention of groin and hip adductor injuries. The main research question was whether training with the isokinetic device produces different and potentially greater adaptations than the Copenhagen adduction exercise and no specific training. The study hypothesis was that device-based eccentric training would lead to greater improvements in hip adductor strength and related functional and muscle characteristics than copenhagen adduction exercise training, while the control group would show little or no change.

Interventions
Isokinetic device-based hip adductor training
An 8-week, twice-weekly hip adductor training program performed using an isokinetic device. The exercise involved controlled eccentric contractions of the hip adductors. The device moved the lower limbs into hip abduction at a controlled angular velocity while participants resisted the movement with the hip adductor muscles. Training volume was progressively increased over the intervention.
Copenhagen adduction exercise training
An 8-week, twice-weekly hip adductor strengthening program using the Copenhagen adduction exercise. Participants performed the exercise with an emphasis on the eccentric phase, and training volume was progressively increased.
