Acute Effects of Copenhagen Adduction Exercise on the Stiffness and Soreness of the Hip Adductors: A Randomised Controlled Trial with Reliability Assessments

Year: 2026

Type: article

Study designs: Randomized Controlled Trial, Clinical Trial

Abstract: Groin injuries often happen in sports involving quick direction changes, kicking, and rapid movements, with the adductor longus frequently being affected. The Copenhagen Adduction Exercise (CAE) is commonly used to help prevent such injuries. This randomised controlled trial examined the immediate effects of a single CAE session on hip adductor stiffness and perceived muscle soreness in physically active adults, following the CONSORT 2025 guidelines. Twenty-six participants (16 females, 10 males) were randomly assigned to either a CAE group, performing three sets of ten repetitions, or a control group that did not exercise. Stiffness of the adductor longus and adductor magnus was measured with the MyotonPro device before and after the intervention, along with a 0-100-point soreness scale. Intra-rater test-retest reliability for stiffness measurements was high to excellent for both muscles (ICC ≥ 0.93). The CAE group showed a significantly greater increase in adductor longus stiffness (p=0.002) and soreness (p
