Six tests for the assessment of some of the social adaptability dimensions and four scales for sports participation assessment were administrated to a sample of 809 male Zagreb high school seniors.
Using factor analysis technique, twelve dimensions of social adaptability were isolated (two form the item intercorrelation matrix of each test). It was not possible to interpret these dimensions independently of very well known personality factors, which are basically responsible for the type of individual\u27s behavior in some social field.
Statistically significant but not very close relationships between social adaptability dimensions and intensity of sports activity were obtained using regression analysis. These relationships were explained by the influence of different regulative mechanisms. It would appear that among them the greatest importance could be attributed to the control mechanisms, which regulate the degree of excitation and inhibition of the central nervous system functions
