The aim of the study was to describe and compare kinematics in two types of execution of attack hit, the goofy approach and regular approach. The research group consisted of players from the Czech Republic's top league (n = 12, age 28.0 ± 4.3 years, body height 196.6 ± 5.6 cm, body mass 89.7 ± 6.7 kg) divided into two groups according to the individual type of approach in the attack. Analysis of movement was performed by 3D kinematics video analysis, space coordinates were calculated by the DLT (Direct Linear Transformation) method together with interpretation software TEMA Bio 2.3 (Image Systems AB, Sweden). The players started their run-up from a distance of about 4 - 4.5 m from the net with similar maximal vertical velocity (2.91 - 2.96 m⋅s(-1)). The trajectory of players with goofy approach seemed to be convenient for the rotation of shoulders and hips in the moment of ball contact. Differences between both groups were observed. Players with a goofy approach had a longer flight phase compared to regularly approaching players.

Článek se zabývá problematikou chápání a definování pojmů „rozehra“ a „herní činnost jednotlivce bez míče“ v české volejbalové teorii a systematice. Jeho potřeba vyplynula jednak z významných změn, které se v posledních 15 letech ve světovém volejbalu objevily a jednak z nejednotnosti pohledu a výkladu obou pojmů v České republice, což se výrazně negativně odráží jak ve výuce studentů TV a trenérů volejbalu všech úrovní, tak i v jejich následné praxi. Snahou předložené práce je poukázat na rozdíly, některé logické nesprávnosti a chybějící články v chápání obou pojmů, pokusit se nabídnout dílčí řešení a zároveň inspirovat hlubší studium dané problematiky. To by se mělo promítnout zvláště do odstranění nelogičností a do sofistikovanějšího zpracování otázek souvisejících s vymezením obou pojmů a výčtem ve hře se vyskytujících herních činností jednotlivce bez míče, které v současnosti teorie a systematika volejbalu prakticky neregistruje.
The article deals with the issue of understanding and definitions of notions "rally" and "basic skill without ball" in Czech terminology and systematics of volleyball. Its need resulted on the one hand from significant changes, which has occurred in world volleyball during the last 15 years and on the other hand from disunity of views and explanations of both terms in the Czech Republic, what reflects very negatively both in tuition of P.E. students and volleyball coaches of all levels, as well as in their successive practice. Presented work strives to refer differences, some logical incorrectness and missing segments in understanding of both notions, to try to offer partial solutions and at the same time to inspire deeper studies of given issues. This should project specifically in eliminating illogicalities and into the more sophisticate elaboration of questions connected with delimitation of both notions and the enumeration of basic skills without ball occurring in a game that current theory and systematics of volleyball almost did not recognize.
