Abstract: The research was conducted in order to determine the structure of conative characteristics of volleyball players. To determine the structure of the treated anthropological dimensions, 100 volleyball players were tested. For the assessment of conative characteristics, CON6 measurement instrument was selected to assess the following conative regulators: activity regulator (EPSILON), regulator of organic functions (CHI), regulator defense reactions (ALPHA), regulator of attack reactions (SIGMA), system for coordination of regulatory functions (DELTA) and system of integration of regulatory functions (ETA). All data in this study were processed at the Multidisciplinary Research Center of the Faculty of Sport and Physical Education, University of Pristina, through the system of data processing software programs developed by Popovic D. (1980), (1993) and Momirović K. & Popovic D. (2003). Based on the Guttman criterion λ6, three principal components were obtained that explained 70.30% of the total variance of the variables (Table 1). Thereby, already the first characteristic root extracted 29.88% of the common variance of the variables. Most of the variables have large positive projections on the first principal component: ETA .87, CHI .69, DELTA .65. This principal component is, undoubtedly, behaves like the general conative factor. The second principal component explains 22.31% of the variance, and the variable for regulation of defense reactions has the largest projection on it — ALPHA .83. The third principal component explains 17.16% of the variance, and the variable for regulation of attack reactions SIGMA .72 and variable EPSILON .66 have the largest projections on it.
