The study included 55 female athletes aged between 13 and 17. Demographic data of the athletes were collected, followed by the administration of the Sport Mental Toughness Inventory and the Psychological Skills Inventory for Sports. Afterward, a 15-minute dynamic warm-up routine was completed, followed by the Illinois Agility Test. The 20-meter shuttle run test was also administered. The two measurement sessions were conducted 48 hours apart. Statistical analyses were performed using SPSS Statistics software version 26.0. For regression graphics, the Jamovi statistical analysis program version 2.6.2.0 was utilized. Mean, standard deviation (SD), linear regression, and skewness-kurtosis values of the variables were calculated for the entire sample . There is no statistically significant relationship between the change of direction values of the football players and the mental endurance and psychological skill variables. While there is no statistically significant correlation between the endurance values of the football players and mental endurance, there is a moderately positive and statistically significant correlation between the endurance values and psychological skill. Psychological skills have a positive effect on aerobic endurance in adolescent female football players, whereas mental toughness does not appear to have an effect. Additionally, neither psychological skills nor mental toughness were found to have an effect on change of direction performance.}, number={2}, publisher={Hasan ŞAHAN}
