Abstract

The aim of this study was to determine the changes in the range of selected coordination elements in subjects of various age with possible disclosure of periods of marked improvement or worsening of the coordination elements. In Poland the materia came from sectional studies (n=433) and longitudinal ones (n=23). Starostas test estimating in a complex manner the various elements of movement coordination was generally used. The material collected from GDR comprised the results of sectional studies (n=2500) and longitudinal ones (n=130). The ability of coordination in the examined persons was estimated by a comparison of 5 tests. The results disclosed the occurence in children between the age of 7 to 11 sensitive periods in the development of movement coordination. Critical periods (stagnation or a certain regression) in the development of movement coordination occured between the age of 11 to 13,6. More distinct changes were observed when individual results were analysed. Verf.-Referat
