Title The genetic predisposition of a speed ability among the players of the 1st and 2nd Czech football league. Study aim To determine the impact of ACE I/D, ACTN3 R577X, AMPD1 Gln12X, BDKRB2 9/+9, IL1RN VNTR, NOS3 Glu298Asp, UCP2 Ala55Val polymorphisms genotype frequencies on the results of the speed ability motor tests. Methods DNA samples obtained from epithelial mouth were quantified and analyzed using the PCR method from 106 football players of the 1st and 2nd Czech football league (age 25,3 ± 4,69; weight 77,5 ± 7,33; height 181,2 ± 6,23). Genotype frequencies were estimated for the ACE I/D, ACTN3 R577X, AMPD1 Gln12X, BDKRB2 9/+9, IL1RN VNTR, NOS3 Glu298Asp, UCP2 Ala55Val polymorphism. Motor speed ability was tested by the vertical jump height, produced power and power impulse for the countermovement jump, countermovement jump without arms swing and squat jump. Isokinetic maximal power of flexors and extensors of the knee were tested at the angle speed 60ř.s-1 , 180ř.s-1 , 300ř.s-1 . Χ2 test (Pearson's chi-square test) was used to determine the genotypes difference for the parameters of the motor speed ability tests in the football players who exceeded 80th percentil compare to the other football players. Kruskal- Wallis test was used to determine dependence (p = 0,05) of the genotypes...
