Football is the most popular sport in the Republic of Croatia, the figure of 69,160 can confirm that, which consists of registered players from U8 to U19 on 31.12.2020 according to HNS. This number includes only registered players also known as competitors. Most football clubs in Croatia are organized in a way that allows taking part for everyone who wants to play this sport. Since the categories are limited in terms of the number of players, clubs select children into competitors and non-competitors. The aim of this study was to determine whether there is a significant difference in the level of motor skills between U12 football players competing and non-competitors. The sample of respondents consists of 34 football players average age 12,7 ± 3, height 160,33 ± 3,76 cm and weight 46,6 ± 8,92 kg of which 17 are competitors and the other 17 are non-competitors. Hypothesis H1 is set; there is a significant difference in the level of motor skills between a group of competitors and non-competitors. Sprint tests at 5, 10 and 20 meters, 93639 with a 180° turn, long jump and technique with the left and right foot gave an insight into the level of speed, agility, explosive power (jumping) and specific coordination. Ttest for independent samples indicated a statistically significant difference in tests SPR20M (t = -3.11; p = 0.00), 93639OK (t = -2.47; p = 0.02) and TEHLD (t = 3 , 40; p = 0.00), and no statistically significant difference was shown in the tests SPR5M (t = -0.50; p = 0.62) SPR10M (t = -1.78; p = 0.08) and SKUD (t = 3.40; p = 0.19). Multivariate analysis of variance (ANOVA) found a statistically significant difference between the group of competitors and the open school (F = 5.336; p = 0.00).
