Coordinative motor skills play a very important role in football. The target of this paper was to analyze coordinative motor skills of 12-year-old boys training football in half a year training cycle. 23 12-year-old boys who train football and 23 12-year-old boys who do not train football were diagnosed. The diagnosis was repeated after 6 months. The most popular version of Starosta’s global coordination test, with jumps to the left and right, was used to determine global motor coordination variance. Eyes and both upper and lower limbs lateralization was determined. Weight, height, length of limbs and legs muscles were measured. Somatic features of the boys did not change in a statistically significant way between the two diagnoses. However, the group of non training boys had a higher rate of both thighs muscles than the group of footballers in the first diagnosis (p ≤ 0.01). Statistically important difference in global motor coordination between the two diagnoses was determined only for the group of football training boys, and only for the results of their left legs (p ≤ 0.05). No statistically important correlation between lateralization or stature of diagnosed boys and their global motor coordination results were discovered. This configuration of the research results proves first of all the influence of football training on the level of global coordination skills. It means that Starosta’s global coordination test is a good method for testing coordinative exercises effects in young footballers’ training. The research was accomplished within the framework of grant no. N N404 255740 (40 contest), financed by the National science centre in Krakow.
