Abstract.With the aim to investigate the plyometric training model
used for the increase of explosive type strength (the vertical jump), an
experimental research was carried out, drawing a sample of 33 volleyball
players at the cadet level. Guided by the general principles of plyometric
training, individual training plans were devised. In order to evaluate
the effect of the sport training on the development of the vertical jump,
three variables were applied. For the purposes of this research, two tests
for the evaluation of the volleyball vertical jump were validated: the
block jump and the spike jump. The experiment was carried out in the second
part of the preliminary period, and it lasted for eight weeks, during which,
two to three training sessions per week were held. The control group trained
using technically tactical contents. The data was processed using univariate
and multivariate analyses as well as a covariance analysis. Based on the
findings of the research and the discussion, one could unfailingly conclude
that the exercise model for the development of the vertical jump that had
been used, as the fundamental factor of the experimental group, has contributed
to the statistically relevant difference in the increase of the vertical
jump in comparison to the control group, which had used technically-tactical
contents to develop the vertical jump.

EFEKTI PLIOMETRIJSKOG MODELA SPORTSKOG
TRENINGA ZA RAZVOJ SKOČNOSTI ODBOJKAŠA
Sa ciljem da se ispita pliometrijski model treninga za razvoj eksplozivne
snage (skočnost) organizovano je eksperimentalno istraživanje na izorku
od 33 odbojkaša kadetskog uzrasta. Rukovodeći se opštim principima za pliometrijski
trening sačinjeni su individualni planovi treninga. Za procenu efekata
sportskog treninga za razvoj skočnosti primenjene su tri varijable. Za
potrebe ovog istraživanja validirana su dva testa za procenu odbojkaške
skočnosti: skok u bloku i skok u smeču. Eksperiment je realizovan u drugom
delu pripremnog perioda, a trajao je osam 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 primenjen model vežbi za razvoj skočnosti, kao osnovni faktor u eksperimentalnoj
grupi, doprineo statistički značajnoj razlici u povećanju skočnosti u odnosu
na kontrolnu grupu koja je za razvoj skočnosti koristila tehničko-taktičke
sadržaje.
