Abstract. With the aim of evaluating the effects of plyometric training on the development of jumping agility, an experimental research program was carried out on a sample of 38 cadet volleyball players. Following the general principles of plyometric training, individual training programs were constructed. In order to evaluate the effects of plyometric training on the development of jumping agility, six variables were used. For the purpose of this research, all six tests for the evaluation of jumping agility were validated. The experiment was realized in the second part of the preliminary period, and lasted for six weeks with two to three training sessions per week. The training of the control group involved technical-tactical exercises. The data were processed with the help of a univariate and multivariate analysis of covariance. On the basis of the research results and the discussion, we can with great certainty conclude that the exercise model that was used, as the basic factor of the experimental group, made a statistically significant contribution to the difference in the increase in jumping agility in comparison to the control group which used technical-tactical exercises for the development of jumping agility.
Key words:  plyometric training, jumping agility, experiment, volleyball players

EFEKTI PLIOMETRIJSKOG TRENINGA NA RAZVOJ SKAKAČKE AGILNOSTI KOD ODBOJKAŠA
Sa ciljem da se ispitaju efekti pliometrijskog treninga na razvoj skakačke agilnosti organizovano je eksperimentalno istraživanje na uzorku od 38 odbojkaša kadetskog uzrasta. Rukovodeći se opštim pricipima za pliometrijski trening sačinjeni su individualni planovi treninga. Za procenu efekata pliometrijskog treninga na razvoj skakačke agilnosti primenjene su šest varijable. Za potrebe ovog istraživanja validirano je svih šest testova za procenu skakačke agilnosti. Eksperiment je realizovan u drugom delu pripremnog perioda, a trajao je šest nedelja sa po dva do tri treninga. Kontrolna grupa je trenirala primenjujući tehničko taktičke sadržaje. Podaci su obrađeni univarijantnim i multivarijantnim analizama i analizom kovarijanse. Na osnovu rezultata istraživanja i diskusije može se pouzdano zaključiti da je primenjeni model vežbi, kao osnovni faktor u eksperimentalnoj grupi, doprineo statistički značajnoj razlici u povećanju skakačke agilnosti u odnosu na kontrolnu grupu koja je za razvoj skakačke agilnosti koristila tehničko-taktičke sadržaje.
