International Journal of Sport Studies for Health 2588-5782 9 Serial Number 26 2026 06 13 Psychophysiological Responses to Competitive Anxiety, Stress Biomarkers (sCort and sAA), and Performance in Elite Female Basketball Players Psychophysiological Responses to Competitive Anxiety, Stress Biomarkers (sCort and sAA), and Performance in Elite Female Basketball Players 1 12 10.61838/kman.intjssh.5162 EN Journal Article 2026 03 28 <table> <tbody> <tr> <td> <p><strong>Objective:</strong>  This study examined the associations between competitive anxiety, self-confidence, salivary cortisol (sCort), salivary alpha-amylase (sAA), and performance outcomes in elite female basketball players.</p> <p><strong>Methods and Materials: </strong>In this observational cross-sectional study, 30 elite female basketball players (mean age = 16.4 ± 0.9 years) competing at national and international levels were included. Psychological states were assessed using the Persian version of the Competitive State Anxiety Inventory-2 Revised (CSAI-2R) approximately 1 hour prior to competition. Saliva samples were collected 30 minutes before competition to measure sCort and sAA. Pearson correlation and multiple regression analyses were performed to examine associations and exploratory multivariable relationships.</p> <p><strong>Results: </strong>Higher levels of cognitive and somatic anxiety were significantly associated with lower free-throw and field-goal percentages and with more turnovers, whereas self-confidence showed the opposite pattern. Pre-competition sCort and sAA were positively associated with anxiety and negatively associated with self-confidence. In exploratory multivariable analyses, overall regression models were significant for several performance indicators, although individual predictors in enter models were not significant, suggesting substantial shared variance among predictors. In backward exploratory models, sAA, self-confidence, and cognitive anxiety/sCort combinations were retained in models of selected performance outcomes.</p> <p><strong>Conclusion: </strong>These findings highlight the importance of integrated psychophysiological monitoring in elite sport. Combined psychological and physiological assessments may support coaches and practitioners in optimizing performance and managing competitive stress in high-level athletes.</p> </td> </tr> </tbody> </table> https://www.journals.kmanpub.com/index.php/Intjssh/article/download/5162/10397
