Comparison of Cognitive Performance an‎d Volleyball-Specific Skills in Volleyball Players with Different Competitive Levels

رفتار حركتي و مديريت ورزش

Success in team an‎d complex sports such as volleyball requires rapid processing of environmental information an‎d precise execution of movement patterns. Therefore, a comprehensive assessment of both mental an‎d physical indicators seems essential in the path of sports development. This study aimed to compare the cognitive performance an‎d technical skills of volleyball players at different competitive levels. In this regard, cognitive variables, including reaction time, decision-making accuracy, an‎d working memory, were assessed alongside specific technical skills such as spiking, passing, an‎d blocking. The data derived from the playersʹ performance in three categories: the main team, youth, an‎d junior levels, were analyzed using statistical methods including covariance analysis, variance analysis, an‎d Pearson correlation matrix. To achieve pure an‎d accurate results, the effects of intervening an‎d confounding variables such as age, training history, an‎d body mass index were carefully controlled. The findings of the research indicated that the average scores of all dependent indicators showed significant differences across various competitive levels. Players from the clubʹs main team performed better an‎d exhibited lower stan‎dard deviations in executing technical skills an‎d cognitive tests compared to the youth an‎d junior categories. The results from the correlation analysis confirmed a significant inverse relationship between reaction time an‎d the quality of skill execution, such that quicker processing of stimuli led to better execution of sports techniques. Furthermore, a direct an‎d significant relationship was found between working memory level an‎d decision-making accuracy with success in executing complex volleyball techniques. The effect size values also indicated a substantial contribution of competitive level in explaining the variance of performance variables. Accordingly, all main an‎d secondary hypotheses regarding the existence of significant cognitive an‎d motor differences among the three team categories were confirmed. Overall, the results of this study demonstrated that achieving peak athletic performance requires the synchronization an‎d balanced development of neural an‎d muscular capabilities, with experience in professional arenas leading to stable mental an‎d motor adaptations.
