 The study found that elite women handball players tend to have an internal locus of control, meaning they take responsibility for their actions and feel able to control events in sports-related areas. However, they share responsibility with the social environment in areas such as family relationships and health. Additionally, a correlation was identified between the internality of locus of control and the ratio of nervous processes in these athletes. The data suggests that an internal locus of control is associated with a more optimal functional state of the central nervous system.
