Zbornik radova 2011, 173–182Slika 8: Izbačaj jednom rukom, zalet tri koraka, odraz sa obe nogeFigure 8: Toss with one hand, three-step momentum, reflection from both legsIt starts with the left foot, then right, left foot and reflectionwith both feet and kicks the ball. As it can be seen from thepicture above, landing after kick is behind the baseline atabout 1.5m to 2m. This method is often done so that thelanding after the service is in the field, or to reflect the serviceright next to the baseline.As with other modes of service delivery, certain irregularitiesand errors can occur during the delivery of the jump floatservice. These errors are often an inadequate initial position,incorrect steps during a drop ball, inadequate ball heightand manner of jump ball. In addition, the ball is not hit toreach the highest point, and it is often inadequate handcontact with the ball which causes ball rotation.ConclusionKreće se lijevom, zatim desna, lijeva, te odraz sa obe nogei udarac po lopti. Kao {to se može vidjeti na slici gore, doskokposlije udarca je iza osnovne linije na otprilike 1.5m do2m. Ovaj način se često izvodi i tako da doskok poslijeservisa bude u terenu, odnosno da odraz za servis bude tikuz osnovnu liniju.Kao i kod drugih načina izvođenja servise i kod izvođenjaflot servisa iz skoka dolazi do određenih nepravilnosti igre{aka. Te gre{ke su najče{će u neadekvatnom početnomstavu, pogre{nim koracima pri podbacivanju lopte, neadekvatnavisina podbačene lopte i način podbacivanje. Osim toga,lopta se ne udara u najvi{oj tački dohvata, a čest je i nepravilankontakt dlana i lopte, zbog čega dolazi do rotacije lopte.ZaključakEvery technical element in volleyball, including service, is aunit of movement of players and a ball, and those interrelationshipsof movement of players and a ball are governedby certain principles. These laws are studied and analyzed,and the purpose of this analysis is to improve and facilitatefurther development and efficiency of service. Ability andknowledge of service delivery, with the right individual andcollective tactical implementation of services, can often bethe deciding factor in the final outcome of the game. Whatevery coach and player should and must know is that duringservice delivery there is no need to hurry, unless this is partof the tactic. The player needs to remain calm, maintainingcomposure and complete concentration. Each service hasits advantages and disadvantages, so the eternal dilemma ofcoaches and players is which service should be applied inthe most vulnerable stages of the game.Should you apply a strong spike service with a huge risk andthe possibility of major errors or use a weaker service withoutrisk, thus providing an opportunity for the opponent toplay around it, is a matter of choice at the given moment.However, the strategy applied by the Serbian coach at thelast European Championship may have surprised many, butalso showed that the service can be just as unpleasant anddisrupt the reception of the opponent, and there’s less riskof error in the service when it’s performed from the jumpwithout rotation (float service). Today, this service is rightSvaki tehnički elemenat u odbojci, pa tako i servis, predstavljajednu cjelinu kretanja igrača i lopte, a ti međusobniodnosi kretanja igrača i lopte su regulisani određenim zakonitostima.Te zakonitosti se proučavaju i analiziraju, asvrha te analize je da se pobolj{a i omogući dalji razvoj iefikasnost servisa. Sposobnost i znanje izvođenja servisa, uzispravnu individualnu i kolektivnu taktičku realizaciju servisačesto mogu da budu odlučujući faktor u krajnjemishodu utakmice. Ono {to svaki trener, pa i igrač trebaju imoraju znati je da se pri izvođenju servisa ne treba žuriti,osim ako to nije dio taktike. Igrač treba da zadrži mirnoću,staloženost i potpunu koncentraciju.Svaki servis ima svojedobre strane, ali i nedostatke, pa je vječita dilema trenera iigrača koji servis u najosjetljivijim fazama utakmice trebaservirati.Da li odservirati jak smeč servis sa puno rizika i velikommogućno{ću gre{ke ili slabiji servis bez rizika i na taj načinpružiti priliku protivniku da se razigra, stvar je izbora u datomtrenutku. Međutim, ono {to je radio selektor Srbije na zadnjemevropskom prvenstvu možda je mnoge iznenadilo, alii pokazalo da servis koji može biti isto tako neugodan iporemetiti prijem protivniku, a uz to je i neuporedivomanji rizik od gre{ke kod njegovog izvođenja je servis izskoka bez rotacije (flot servis).
