A Morphological Study in Volleyball Athletes With Cronic Ankle Instability

July 5, 2023 updated by: Aynur Demirel, Hacettepe University

Kronik Ayak Bileği İnstabilitesi Olan Voleybolcularda Denge ve Patlayıcı Güç Üzerine Morfolojik Bir Çalışma

The former purpose of this study to investigate the effect of transverse abdominis, lumbar multifidus, vastus lateralis, lateral gastrocnemius, anterior talofibular ligament of morphology on explosive power and balance performance in cronic ankle instability with volleyball players. The latter purpose of this study to determine morphological characteristics volleyball players with and without cronic ankle insatbility of trunk muscle morphology, field tests and the muscle morphology features between the body affected and unaffected sides whose those with chronic ankle instability.This study was designed as a cross-sectional. Twelve volleyball players with chronic ankle instability who meet the criteria determined by the ankle consortium will be included in study group. Twelve asymptomatic volleyball players who have been training at least three days a week for at least one year will be include in the control group. They will consist of 24 volleyball players between 14-35 years of age.Morphological characteristics of anterior talofibular ligament, transverse abdominis, lumbar multifidus, vastus lateralis, lateral gastrocnemius will be evaluated via ultrasound, explosive power with squat jump, counter movement jump and balance performance by Y-Balance Test. Trunk muscle morphology, core stabilization, explosive power, balance performance will have been compered in volleyball players with and without chronic ankle instability. The effects of morphological features on explosive power and balance performance will have been determined. It is anticipated that by determining the parameters that can be affected by instability with volleyball players, it will guide the professionals working in the field, countribute to treatment and preventive treatment programs.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 30 years (Child, Adult)

Accepts Healthy Volunteers

Yes

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
