Investigation of the Effect of Cognitive Dual-Task on Athletic Performance Parameters in Volleyball Players With and Without Chronic Ankle Instability

Overview

The aim of this study is to investigate the effect of the cognitive dual-task on athletic performance parameters in volleyball players with and without chronic ankle instability. In addition, it will examine how a pathology in the lower extremity affects upper extremity function.

Detailed description

This project is a cross-sectional and comparative study designed to investigate the effects of cognitive dual-task conditions on athletic performance parameters in volleyball players with and without chronic ankle instability (CAI). Chronic ankle instability is characterized by recurrent ankle sprains and a sensation of "giving way," and may lead to impairments in sensorimotor control, postural stability, and neuromuscular functions. Current approaches indicate that this pathology affects not only peripheral structures but also the central nervous system and cognitive processes. However, how CAI under cognitive load is reflected in upper extremity function through the kinetic chain has not been sufficiently investigated.

Volleyball players aged between 18 and 25 years who are actively playing volleyball will be included in the study. Participants will be divided into two main groups: those with CAI and a healthy control group; the CAI group will also be classified as unilateral and bilateral. In all participants, static balance, dynamic balance, lower extremity strength, ankle dorsiflexion range of motion, upper extremity functional performance, and spatiotemporal parameters of running will be evaluated under single-task and cognitive dual-task conditions.

The originality of this study lies in addressing not only lower extremity functions in CAI but also upper extremity performance and its interaction with cognitive processes through the kinetic chain, using a holistic approach. The findings obtained are expected to clarify the role of cognitive load on athletic performance in individuals with CAI and to contribute to the planning of more functional and holistic athlete assessment and rehabilitation programs.
