Effects of the quality of selected kinds of game skills of an individual on the set outcome in men’s top-level volleyball
51
Hendel (2009) was used. Significance of differences was assessed on the 5 % and 1 % level
of statistical importance. The kind of a particular game skill, in which significant differences
in the quality of its realisation between teams winning and losing a set were found, was
considered an indicator of the team’s success in a set.
For interpretation of results, logical methods, such as analysis, synthesis, inductive and
inductive/deductive procedures were used.
Results and discussion
Frequency of occurrence of individual kinds of the assessed game skills
of an individual
Total 2 503 attack hits in matches were assessed. From the aspect of individual investigated
kinds of attack hits, most of them were spikes (84.2 %). When compared to spikes,
considerably lower was the number of technical hits, such as lobs or tips (6.1 % and 9.7 %
respectively).

Figure 1
Frequency of occurrence of individual kinds of attack hits
We assessed total 2 273 blocks. In the assessment of frequency of individual kinds of
blocks from the aspect of blockers, it was found that a match includes mostly double blocks
(55.7 %) and single blocks (28.4 %). The recorded number of triple blocks was considerably
lower (12.5 %) and the least of all occurred a situation where the defending team failed to
set up a block (3.4%). Failure to set up a block was not assessed in game situations where
the attacking team failed to create conditions for attack termination, but only for pushing
the ball to the opposite side. This way, only the situations where the defending team was
unable to block the opponent's attack that could end by any of the above hits were assessed.
The reason could be a surprising attack, bad evaluation of the game situation, etc. The
dominancy of group blocks (double block, triple block) is clear and confirms the basic
