Aim: The aim of the study is to provide a new tool to measure the level of defensive agility objectively. Methods: The sample included 14 elite male volleyball players of the University of Nitra club (22.3 ± 5.7 years). Measurements consisted of body height (BH); body weight (BM); body mass index (BMI), and the defensive agility test (DRAT (test-retest)) with an interval of one week between the two tests using an electronic timer (Witty photocell) and Witty SEM lights (Microgate, ITA). The validation included assessing the equality of mean values in the test and retest (t-Student), effect sizes with Cohen’s d, analysis of variance (ANOVA), intraclass correlation coefficient determinations (ICC model), and random intercept correlation (Φ). Results: The results indicated no significant differences in both tests except for left movement (p = 0.0255). The ICC value of the test time was statistically significant (0.91); standard error of measurement (SEM = 0.02); repeatability coefficient (RC = 0.20); minimal difference (MD = 0.04). Effect sizes were trivial to small (d = ˂−0.05–0.17>; right), medium (d = 0.35; backward) a large (d = −0.67; left). Conclusions: The DRAT test showed excellent reliability in total time (ICC = 0.91). Validation of the DRAT test’s consistency, reliability, accuracy and validity can help coaches make decisions about evaluating and monitoring defensive reactive agility performance in sports games. |
