A sample consisting of 487 children (249 male and 236 female) aged 7–9 years ( 2 months) underwent programmed kinesiologic transformation procedures for 18 months. The morphological and motor development was followed up by use of 14 morphological and 12 motor variables at 9-month intervals. Three taxonomic analyses for each measurement time point were calculated for either sex in order to determine the initial and transitive position for each individual study subject, and to identify most homogeneous groups within the sample as a whole. Three taxonomic variables were isolated on each measurement for either sex. Study results revealed female children to undergo faster development with earlier formation of the three morphological-motor structures ranked according to their predominance: mass, i.e. ectomesomorphy, motor, and endomorphy. Entity projections upon taxonomic variables at particular measurement points clearly identified the morphological-motor variables to be addressed by general and differentiated programs of kinesiologic education in order to achieve optimal effects during the development of the child’s body as a whole.
