Psychological Factors, Sleep Quality, and Injury Prevalence among Iranian Taekwondo Athletes (November–December ۲۰۲۳): A Cross-Sectional Study

Background: This study investigated the prevalence of injuries among Taekwondo athletes, with specific emphasis on psychological attributes, namely competitive anger and aggression, as well as sleep quality. Although these factors are recognized contributors to sports-related injury risk, their association with Taekwondo-specific injuries remains insufficiently explored. The research aimed to identify injury patterns and evaluate the relationships between these psychological constructs, sleep quality, and injury incidence to guide targeted prevention and management approaches. Methods: A cross-sectional survey was administered in Tehran between November and December ۲۰۲۳ to ۲۰۱ Iranian Taekwondo practitioners. Participants completed a validated Farsi-language online questionnaire capturing demographic information, training characteristics, scores on the ۱۲‑item Competitive Aggressiveness and Anger Scale (CAAS), the ۱۹‑item Pittsburgh Sleep Quality Index (PSQI), and self-reported musculoskeletal injuries over the preceding six months. Data analyses employed descriptive statistics and multivariable logistic regression to determine independent predictors of injury. Results: Among respondents, ۱۱۸ athletes (۵۸.۷%) reported at least one injury, most commonly involving the ankle (۲۰.۶%) and foot/toe (۱۷.۶%). Adjusted regression analyses revealed that each one‑point increase in CAAS score was associated with greater injury risk (OR = ۱.۲۳; ۹۵% CI ۱.۱۱–۱.۳۶; p < ۰.۰۰۱), as was each one‑point increase in PSQI score (OR = ۱.۱۲; ۹۵% CI ۱.۰۵–۱.۳۸; p = ۰.۰۰۶). Training more than three sessions per week (OR = ۴.۰۱; ۹۵% CI ۱.۹۳–۸.۳۳; p < ۰.۰۰۱) and session durations exceeding ۶۰ minutes (OR = ۲.۲۷; ۹۵% CI ۱.۰۷–۴.۸۴; p = ۰.۰۳۲) were also independent predictors. Conclusion: The findings underscore the need to systematically assess competitive aggressiveness, anger, sleep quality, and training load when formulating injury prevention and management strategies for Taekwondo athletes.
