Relliability of The Tests of Maximal Kicking Performance in Youth Croatian Soccer Players
The basic aim of this research was to analyse the reliability of 8 tests for evaluation of kicked soccer ball velocity. The research was conducted on the sample of 42 (15.7±1.5 years) youth soccer players who kicked the ball without and after dribbling. All the kicks were performed with dominant and non-dominant leg. The kick speed was evaluated by pocket radar. The values of the Cronbach alpha (CA) and Spearman-Brown (SB) reliability coefficients were higher than 0.80 in all the tests. Somewhat lower values of Inter-item correlation (IIC) were reported in tests performed with a dominant leg. The variance analysis showed a systematic error (the learning effect) only in first test, indicating a need of performing a greater number of trials before the real test. It can be concluded that kicked soccer ball velocity tests in which the pocket radar was applied had good metric characteristics.
