Purpose. The aim of the study was to determine therel ationships between physical fitness and selected personality traits in adolescents, as well as their gender-related diversification. Personality traits determining the level of physical fitness were also examined. Basic procedures. The number of participants ranged from 414 to 515 high-school students (depending on the questionnaire) aged 15–17. The standard questionnaires for assessment of psychological variables (FCB-TI, NEO-FFI, HSPQ) and the International Physical Fitness Test (IPFT) were used. Main findings. Temperament and personality traits were relatively poorly correlated with the adolescents’ physical fitness. The correlations were different in boys and girls. In boys significant correlations were m ore numerous a nd p hysical f itness indices were correl ated mainly with temperament and personality, i.e. biologically determined characteristics. In girls fewer relationships limited to environmentally-determined traits were observed. Crystallzied intelligence was correlated with the results of all fitness tests, but only in boys. In girls fewer correlations were found. Personality traits enable us to predict adolescents’ physical fitness to a very limited extent, and predictors of physical fitness are different in boys and girls. Conclusions. The results indicate that boys’ psychological traits are mainly related to two pillars of physical fitness (“to be able” and “to know”), while girls’ traits to one (“to want”).
