The explosive strength is the capability to perform a jump, to perform a hard blow, and to perform and to create one fast and strong movement, which is momentary. The aim of research was to determine differences in the explosive strength, jump performance and speed between football players with different levels of competition (aged 10 to 12 years). The sample of research were 20 football players of federal level (age 11,31±0,62; height 153,93±7,94 cm; weight 43,18±6,91 kg) and 20 football players of regional level (age 11,05±0,49; height 150,39±8,14 cm; weight 43,13±7,72 kg). The sample of the variables represented six tests of explosive strength - jump performance: standing long jump, triple jump, countermovement jump and speed: sprint on 10m, 20m and 30 m. The results were determined by T-Test for small independent causes. Based on the results, we conclude that there are significant differences between football players with different levels of competition in all variables, and this difference is defined as significantly better results in all tests in favor of the football players with federal level of competition. After processing and the data obtained it can be concluded that the federal league coaches pay more attention to the development of explosive strength and speed than regional rank coaches
