Physical exercises' mastering level in classification of motor preparedness of 11- 13 years old boys

The purpose of the research is to determine features of motor preparedness' classification of 11-13 years old boys considering level of physical exercises' mastering. in the research 11 years old boys (n=58), 12 years old boys (n=76) and 13 years old boys (n=93) participated. The following methods of a research have been applied to solve the tasks: analysis of scientific and methodical literature, pedagogical testing and methods of mathematical statistics. Testing program includes well known tests. Standardized coefficients of canonic discriminant function permit to determine correlation of variables' contribution to function's result. The first function explains variation of results by 80,1% (p
