The aim of this study was to compare the effects of Copenhagen adduction exercise (CAE) at different loading intensities, included in the routine training program, on hip muscle strength improvement; adductor muscle flexibility and jumping performance in adolescent taekwondo athletes. The athletes included in the study were divided into two groups as modified CAE group (n=40) and classic CAE group (n=58). The exercise training was incorporated into the routine training program for both groups for 8 weeks, twice a week. While the classic CAE training was applied dynamically for 8 weeks, the modified CAE training was applied isometrically for the first 5 weeks and dynamically in the following weeks.13 athletes in the modified CAE group (mean age 15.69±1.03 years) and 13 athletes in the classic CAE group (mean age 15.46±1.33 years) completed the study. Measurements were performed at baseline, at 4th week, at 8th week and at 16th week (follow-up). Isometric and eccentric muscle strength of the hip abductors and adductors were measured with a manual hand-held dynamometer; adductor muscle flexibility was measured with a universal goniometer; lower extremity jumping performance was assessed with timed lateral hop and single leg forward hop tests. As a result of the study; it was found that both exercise trainings improved isometric and eccentric hip adductor muscle strength (p<0.008). The hip eccentric adductor strength improvement was higher in the classic CAE group (p<0.05). There was no effect of CAE training on hip adductor muscle flexibility (p>0.008). It was also found that lateral and forward jump performance improved over time in the classic CAE group (p<0.008). Delayed muscle soreness level was higher in the classic CAE group at the 5th week (p=0.021) and at the 8th week (p=0.001). Perceived exertion level was higher in the classic CAE group (p<0.05). In conclusion, for adolescent taekwondo athletes, CAE training is recommended to be performed dynamically for 8 weeks for performance improvement and to achieve advanced eccentric strength improvement in the hip adductors. There is a need for studies to investigate the effects of CAE training on functional performance in different sports.
