Sažetak: U ekipnim sportovima mora postojati igrač specijalizovan za organizaciju igre. U odbojci ta uloga je povjerena dizaču. Nerijetko se može čuti konstatacija da su dizači ''mozak u ekipi''. Time se želi naglasiti da su dizači igrači od kojih zavisi ukupna organizacija igre. Međutim, dizač sa prefi ksom ''vrhunski'' mora ispunjavati određene uslove: funkcionalne, motoričke sposobnosti i antropometrijske ili morfološke karakteristike, ali i zadovoljavati neke zahtjeve. Karakteristika vrhunskih dizača je biti raznovrstan i nepredvidiv naročito prilikom dizanja lopte za napad, tako da svaka njegova akcija ima taktičku opravdanost i bude neočekivana za protivnika. Primarni zahtjevi koji dizač kao specijalista mora ispunjavati jesu pravilna tehnika dizanja lopte, vladanje svim vrstama tehnike dizanja lopte, sposobnost taktičkog mišljenja i sposobnost perifernog vida. Sekundarni zahtjevi koji bi jednog takvog specijalistu činili kompletnim su vladanje tehnikom smečiranja u napadu, a u odbrani preuzimanje uloge pomoćnog tj. krajnjeg blokera. Koliko je moguće ''proizvesti'' takvog igrača, teško je reći, međutim, činjenica je da u savremenoj odbojci postoji pozitivan trend izuzetnih dizača i pored toga što je danas znatno teže uspjeti izboriti se za ovu specifi čnu igračku poziciju u ekipi.

SUMMARY In a study with transversal character participated 40 female volleyball players, selectedby clearly defined critiques. The tests that were conducted are from the domain of specific volleyball coordination (predictors) and the precision of playing a ball with ''bump'' (criteria

Evaluation in women's basketball is keeping up with developments in evaluation in men's basketball, and although the number of studies in women's basketball has seen a positive trend in the past decade, it is still at a low level. This paper observed 38 games and sixteen variables of standard efficiency during the FIBA EuroBasket Women 2019. Two regression models were obtained, a set of relative percentage and relative rating variables, which are used in the NBA league, where the dependent variable was the number of points scored. The obtained results show that in the first model, the difference between winning and losing teams was made by three variables: true shooting percentage, turnover percentage of inefficiency and efficiency percentage of defensive rebounds, which explain 97.3%, while for the second model, the distinguishing variables was offensive efficiency, explaining for 96.1% of the observed phenomenon. There is a continuity of the obtained results with the previous championship, played in 2017. Of all the technical elements of basketball, it is still the shots made, assists and defensive rebounds that have the most significant impact on the final score in European women's basketball. It can be noted that, unlike with the previous championship, inside play is no longer dominant, but there is a balance between inside and outside play, which has already been established as a developing trend in men's basketball. The emergence of the offensive efficiency variable indicates that it is becoming significant in top-tier competitions as well but is still a challenge for coaches to grasp the causes of this multicomplex issue based on this indicator.

The subject of this research project is precision as a factor of success of the male volleyball players. The issue relates to the realization of the said motor skills through a clearly defined and valid metric tests typical for the area of technical-tactical structure of volleyball. The aim of the study was to determine the factorial structure of motor abilities of precision for male volleyball players. The task was to determine the correlation between motor tasks with the main components defined as potential factors of the research area. The sample consisted of 40 male volleyball players, members of volleyball teams from Niš (SRB), 14-16 years of age. Eleven motor tests were used to assess the following potential factors: the precision of shooting targets in the horizontal plane, the precision of shooting targets in the vertical plane, body coordination at the volleyball court, the precision of spike technique and nerve-muscle reactions. It was found that there are certain manifest dimensions within the subjects area defined as the area of precision. Then, in the structure of this region in volleyball, acting as precision factors in shooting targets with fingers and "bump" in the horizontal and vertical planes, also confirmed that the coordination of work and factor in the space of volleyball courts and a velocity factor of nervemuscle response. In general it is concluded that within the structure of technical-tactical elements operate particular types of precision in volleyball, that can be defined as factors of precision in the technique of adding a ball with fingers, forearm pass technique ("bump") and spike technique.

Predmet ovog istraživanja jeste preciznost kao faktor uspješnosti kod odbojkaša i odbojkašica. Cilj u istraživanju je da se utvrdi struktura antrpomotoričke sposobnosti preciznosti za odbojkaše i odbojkašice. Uzorak ispitanika činilo je ukupno 80 odbojkaša i odbojkašica, članova odbojkaških klubova starosti od 14 do 16 godina. Korišteno je 6 motoričkih testova za procjenu sljedećih sposobnosti: preciznost pogađanja ciljeva u horizontalnoj ravni, preciznost pogađanja ciljeva u vertikalnoj ravni. Utvrđeno je da postoje određene manifestne dimenzije unutar posmatranog prostora definisanog kao prostor preciznosti. Zatim, da u strukturi ovog prostora kod odbojkaša i odbojkašica, djeluju preciznosti pogađanja ciljeva prstima i ‘’čekićem’’ u horizontalnoj i vertikalnoj ravni. Generalno je zaključeno da u strukturi tehničko-taktičkih elemenata djeluju posebni tipovi preciznosti u odbojci, koji se mogu definisati kao preciznosti u tehnici dodavanja lopte prstima, tehnici dodavanja ‘’čekićem’’ i tehnici smečiranja.
