Abstrakt		The purpose of the study was to establish structural changes of motor dimensions in early adolescence. The sample comprised 195 ten-years-old boys, 160 boys aged twelve, and 195 fourteen-year-old boys. The battery of 26 tests was selected of factor analysis. Eight factors were isolated in each group. Developmental changes of the first factor have shown that with ten-year-old boys motor variables of energy block are prevailing, with twelve-and especially with fourteen-year-olds the first factor was named energy regulation of movement, in the other two groups it is the performance of complex movement structures. The flexibility of trunk, the velocity of simple movements, repetitive strength of the trunk, and the coordination of rhytmic movement are well defined and stable factors. Balance, explosive power of arms, explosive power, synergetic and tonus regulation of movement, agility, flexibility of shoulders and static strenght are developmentally unstable factors with less simple structure or appear only in one or two age groups. In relatively short period of four years, significant structural changes of motor dimensions have appeared.
