Brief Summary

The goal of this observational study is to learn about the frequency and characteristics of adductor-related groin symptoms in adolescent Taekwondo athletes aged 12-17 years. The main questions it aims to answer are: How common are adductor-related groin symptoms in adolescent Taekwondo athletes? Do athletes with these symptoms show differences in hip strength, joint range of motion, or functional level compared to athletes without symptoms? Participants will complete a brief screening about their groin pain and training habits, followed by: Clinical tests of the hip and groin region (resisted adduction, palpation, FABER, and FADIR tests) Strength testing of hip abductor and adductor muscles using a hand-held dynamometer Range of motion measurements of the hip using a goniometer A self-reported questionnaire (Copenhagen Hip and Groin Outcome Score - HAGOS) to assess daily activity and sports function Data from this study will help identify early signs of adductor-related groin problems and guide preventive and rehabilitation strategies for young Taekwondo athletes

Conditions

Groin Injuries; Adductor Strains

Outcome Measures

Primary Outcomes (2)

• Prevalence of Adductor-Related Groin Symptoms

  The presence of adductor-related groin symptoms will be assessed using standardized clinical tests (resisted adduction test and adductor palpation test) based on the Doha classification framework. Unit of Measure: Percentage of athletes with positive test results (%) Purpose: To determine how common adductor-related groin symptoms are among adolescent Taekwondo athletes. Type: Categorical (Yes/No)

  at baseline

• Pain Intensity

  Pain intensity during resisted adduction will be evaluated using a Numeric Pain Rating Scale (NPRS; 0-10). Unit of Measure: Points (0-10 scale). Higher points indicates severe pain. Purpose: To quantify the severity of pain in athletes with adductor-related symptoms.

Secondary Outcomes (6)

• Isometric Hip Adductor Strength

• Isometric Hip Abductor Strength

• Eccentric Hip Adductor Strength

• Eccentric Hip Abductor Strength

• Hip Range of Motion (Abduction and Internal Rotation)

Study Arms (2)

Symptomatic Group (Adductor-Related Groin Pain Group)

This group will include adolescent Taekwondo athletes aged 12-17 years who report groin pain or discomfort during training and test positive for adductor-related symptoms based on the Doha classification framework. Diagnosis of adductor-related groin pain will be confirmed through: Resisted adduction test (pain provocation) Palpation of adductor muscles and tendons Participants in this group will undergo hip strength, range of motion, and functional assessments.

Asymptomatic Control Group (Healthy Control Group)

This group will include age-, sex-, and activity-matched adolescent Taekwondo athletes who do not report groin pain or any lower extremity injury and test negative on the clinical provocation tests (resisted adduction, palpation, FABER, FADIR). They will undergo the same measurements as the symptomatic group for comparison.

Eligibility Criteria

• Age: 12 Years - 17 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)
• Sampling Method: Probability Sample

Study Population

The study population consisted of adolescent Taekwondo athletes aged 12 to 17 years who are actively training at the Göztepe Sports Club, İzmir, Türkiye. All participants held a black belt (professional level) and have at least three years of competitive Taekwondo experience with regular training sessions at least five times per week. Two groups formed: Symptomatic Group: Athletes who report groin pain or discomfort during training and show positive results on clinical tests for adductor-related groin symptoms (resisted adduction and palpation tests). Asymptomatic Control Group: Age-, sex-, and activity-matched athletes without groin pain or any lower extremity symptoms, who test negative on all clinical examinations. All participants are screened by a physiotherapist for eligibility prior to data collection.

You may qualify if:

• Aged between 12 and 17 years.
• Registered as an active Taekwondo athlete at a Sports Club.
• Holds a black belt level (professional) in Taekwondo.
• Has at least 3 years of professional Taekwondo training experience.
• Participates in training sessions at least 5 days per week.
• Able to participate in regular training and competition without restriction.
• Voluntarily agrees to participate and provides informed consent (and parental consent for minors).

You may not qualify if:

• Presence of any orthopedic, neurological, or systemic condition that may affect lower limb function or limit participation in training.
• History of lower extremity surgery (hip, knee, ankle, or foot).
• Current or recent (within the last 6 months) acute lower extremity injury other than groin-related symptoms.
• Refusal or inability to complete the required clinical tests or questionnaires.
