The article presents results of the study designed to explore the self-control styles and volitional domains (meaning the volitional qualities plus the volitional control type) of differently-skilled athletes. Subject to the study (using the Behavioral Self-Control Style method; Volitional Qualities Self-Rating by University Athletes method; and the Action Control Rating method) were 96 individuals of both sexes specialized in different sport disciplines and ranked from Class II Athletes to Sport Masters. The study showed the self-control styles, volitional qualities and volitional control types being in certain correlations. Higher-ranking athletes were found more accurate in rating their performance and results, more advanced in their purposefulness, endurance and self-control abilities, and more initiative and self-reliant.
