Abstract
[b]Background. [/b]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 in girls and to identify the dominant direction of rotation. [b]Materials and methods.[/b] The study involved 53 girls training rhythmic gymnastics, 90 students from ballet schools and 15 professional dancers. The control group consisted of 87 girls. 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 0.99 [3]. [b]Results.[/b] The highest level of global movement coordination was featured by professional female dancers and ballet school students. The lowest level was featured by 7-11-year-old not training girls. 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 Starosta W. 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. After the age of 17 the level of movement coordination, decreased . 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. [b]Conclusions.[/b] Left-handed ballet school students featured higher levels of global movement coordination. Sensitive period of movement development was observed in studied girls between 7 and 10 years of age, whereas the critical period between 11 and 13 years of age. In the girls surveyed the dominant direction of rotation to the right was observed. These results may prove the effect of the movement discipline practiced on the dominant direction of rotation.
