Abstract

The aim of this study was to assess the level of global movement coordination in female dancers and rhythmic gymnasts as well as in girls not training and to determine the level of movement coordination in the left-handed girls of ballet schools. The work herewith attempts to determine the sensitive and critical periods in the development of movement coordination and to identify the dominant direction of rotation. Material and methods. A total of 245 subjects were tested. Measurement of the global movement coordination was carried out using two test tasks and a coordination-meter of W. Starosta [1, 2]. The reliability of the test was 0.94-0.99 [3]. Results. The highest level of global movement coordination was featured by professional female dancers and ballet school students. Among the tested female ballet school students there were three of them who defined their left side of the body (arm and leg) as a dominating one. Each of them received in the test of W. Starosta [1, 2] higher results in the global movement coordination than the mean results for their age group (13, 15 and 16-year-old). The level of global movement coordination "rose" until the age of 15-17. In both test tasks, the test results of the execution of rotation to the right were higher in most girls and women practicing gymnastics and dance.

 

Key words: global movement coordination, symmetry and asymmetry of movements, rhythmic gymnasts, ballet school female students, professional dancers, dominant hand, left-handedness.
