Solving complex tasks in the process of upbringing and education, and influenting on their health, growth and development of the pupils, demands good knowledge of age characteristics, in this case, characteristics of early age children. The purpose of this research is to determine how much is experimental programme, which was conducted during one school year, influenting the morphological characteristics. The applied experimental program was composed of athletics exercises, sports games, exercises on the pieces of equipment and on the floor, rhythmics and dancing exercises and some additional exercises. 13 metrical instruments were used for evaluation of morphological characteristics of male students. Multivariant and univariant analysis of variance for repeated measures (MANOVA and ANOVA - repeated measures) were applied for determination of eventual differences between initial and final measuring. The multivariant analysis of covariance (MANCOVA) and univariant analysis of covariance (ANCOVA) were applied in order to determine the effects of the experimental program. On the basis of the results and discussion, it can be concluded that the experimental program has statistically significant effects on the changes of some morphological characteristics.
