The metric characteristics of specific speed and agility tests in youth soccer players
Abstract
The subject of this study are metric characteristics of specific football tests. 27 football playerschronorogical age of 13-15 years, apropos categories of elder pioneers from HNK CibaliaVinkovci, Croatia. The participants had to go through specific tests with the ball: 20 m sprint,zig-zag, slalom, and 9-3-6-3-9 test. We can conclude that all four variables are highly reliable.The homogeneity of the measuring instrument is good (20 ml) and excellent( zig-zag L, slalomL, 93639 L), and results of skewness and kurtosis further show good sensibility of the measuringinstrument, with the exception 20 m L2 variable, which is positive asymmetrically distributedand elongated. The correlation of particles with first main component, which is second conditionfor homogeneity of the measuring instrument, points on high homogeneity of all tests. Regulardistribution of all test implies on satisfactory reception of all four tests for assessing the speedand agility. The factor analysis has given one significant component and the amount of explaniedvariance and size of characteristic valuables are high, so we could confirm also factorial validitiyof tests. The results of the variance analysis (ANOVA) conclude that the tests are pragmaticallyvalid, and they distinguish players from different playing lines.
