Background: The purpose of the research was to assess the level of overall motor coordination in children practising sport dance - namely, acrobatic rock'n'roll - against the background of their peers who did not dance. The evaluation also included the lateral differentiation of overall motor coordination and skills of kinaesthetic movement differentiation.Material/Methods: The research was conducted in a group of 64 persons aged eight. The research group consisted of thirty children who had practised acrobatic rock'n'roll for a year. The clinical control group was formed by nineteen schoolgirls and fifteen schoolboys who did not practise any sport dance. The research participants' motor coordination level was evaluated by means of a test with the use of Starosta's coordination-meter. The same test was used to assess the lateral differentiation of the turning jump and to evaluate the participants' skill of kinaesthetic movement differentiation.Results: After one year of practice the research group achieved better results as far as their skills of kinaesthetic differentiation and of movement symmetrisation were concerned.Conclusions: After one-year training, both the boys and girls who practiced sport dance showed a higher level of overall motor coordination than non-training children of the same age.
