About this study
Official title: 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.
