Handball and soccer share many common characteristics related to physical demands, technical and tactical skills, mental preparation and development of young players. These similarities make these two sports demanding and exciting and provide different opportunities for mutual comparison and improvement of training processes. The aim of this work was to determine the differences in the agility of children competing at the age of 12 and 13 in handball and football using three tests; T-test, 9-3-6-3-9 test and lateral step which will be performed first on parquet and then on artificial grass. The subjects of this research are 15 handball players from Rk Rovinj and 15 football players from Nk Rovinj, aged 12 and 13. The average age of handball players is 12.27, while the average age of football players is 12.33. The assumption is that soccer players will have better results in all tests, but in the sidestep test we expect the smallest differences due to the fact that the sidestep is a more common form of movement in handball than in football. and 9-3-6-3-9 test on artificial grass where the results are statistically significant in favor of football players. We have no statistically significant deviations in the sidestep test, but the average result of handball players on the floor is still slightly better than soccer players, while on artificial grass the opposite is true, which agrees with our assumption that in this test there will be no big differences in the test 9-3-6-3-9 on artificial grass, soccer players also have on average, better results that are not statistically significant. In the end, we can conclude that differences between handball and soccer players in some forms of agility really exist, and soccer players are definitely better in tests that include different ways of moving and more frequent changes of direction.
