- Brief Summary
The aim of our study is to compare the effects of the Copenhagen adduction exercise, performed at different loading intensities, on hip muscle strength development, performance, flexibility, and delayed onset muscle soreness. The study will include active taekwondo athletes between the ages of 12-18. Athletes will be randomly divided into two groups: a low-intensity Copenhagen Adduction exercise group and a high-intensity Copenhagen Adduction exercise group. Athletes in both the low-intensity and high-intensity exercise groups will perform the exercise for 8 weeks in addition to their regular training program. At the beginning of the study and at the 4th, 8th, and 16th weeks, assessments will be conducted for hip abductor and adductor eccentric and isometric muscle strength, flexibility of the hip adductors, level of delayed muscle soreness, single-leg jump test, and timed lateral hop tests. The outcome of our study will determine how much improvement is achieved in hip muscle strength and lower extremity physical fitness parameters during and after the application of the Copenhagen adduction exercise at different loading intensities.
- Detailed Description
The study is a single-blind randomized controlled trial including male and female adolescent taekwondo athletes (12-18 years). Evaluators will be blinded to which group are assessing.
Participants will be recruited from the local sports clubs. Club coaches will be asked to invite club players. Players interested in participating in the study will be asked to attend a meeting where the study will be explained to them. Those who were interested will then be assessed for inclusion and exclusion criteria.
Interventions:
Sports clubs are allocated to the high-intensity Copenhagen adductor exercise group (HCAE) or the low-intensity Copenhagen adduction exercise group (LCAE). Athletes in both the low-intensity and high-intensity exercise groups will perform the exercise for 8 weeks. Athletes in the HCAE group will perform the classic Copenhagen adduction exercise protocol and at LCAE group will perform the modified Copenhagen adduction exercise protocol.
Testing procedure:
The following tests will be performed before the exercise and 4th - 8th - 16th weeks after the beginning of the exercise.
The isometric and eccentric strength of the hip adductors and abductors Hip adduction flexibility Single-leg hop test Side hop test
A 10-point visual analog scale will be used to record the level of muscle soreness and rate of perceived exertion experienced after each training session.

- Primary Outcome Measures
Name Time Method hip muscle strength beginning and 4th-8th-16th weeks after beginning isometric and eccentric hip adductor and abductor muscle strength will assess with a hand-held dynamometer.
- Secondary Outcome Measures
Name Time Method lower extremity performance beginning and 4th-8th-16th weeks after beginning single leg hop test and side hop test
hip adduction flexibility beginning and 4th-8th-16th weeks after beginning hip adduction range of motion will assess with a goniometer.
delayed onset muscle soreness immediately after each exercise session, through 8 weeks delayed onset muscle soreness will assessed with visual analog scale.
rate of perceived exertion immediately after each exercise session, through 8 weeks rate of perceived exertion will assessed with BORG CR10 scale(Borg Rating Of Perceived Exertion).
