Analiza vpliva kinematičnih parametrov meta na koš s pomočjo "pametne žoge"Erčulj, Frane ...V raziskavi smo z uporabo t. i. pametne košarkarske žoge oz. tehnologije 94Fiftyr želeli ugotoviti povezanost treh kinematičnih parametrov (izmetni čas, vpadni kot, rotacija žoge) z uspešnostjo metov ... na koš ter kako telesna višina in tip igralca (igralno mesto) vplivata na omenjene parametre. Hipoteze smo preverjali na vzorcu 83 košarkarjev povprečne starosti 18 (+-1.1) let, ki so bili v povprečju visoki 196.7 (+-8.8) cm in težki 88.4 (+-11.4) kg. Rezultati raziskave potrjujejo naša pričakovanja, da je skupina najvišjih košarkarjev (praviloma so to centri) manj uspešna pri metu na koš z razdalje 6.75 m. Rečemo lahko tudi, da je njihov izmetni čas v povprečju daljši, vpadni kot pri metu na koš pa manjši kot pri nižjih košarkarjih (krilih in še posebej branilcih). Glede uspešnosti meta lahko ugotovimo linearno povezanost z vpadnim kotom. Igralci, ki so bili bolj uspešni pri metu, so imeli večji vpadni kot. Dokaj zanesljivo lahko rečemo tudi, da izmetni čas v zelo širokem razponu (od 0.7 do 1 s) ni vplival na uspešnost meta. Podobno lahko trdimo tudi za rotacijo žoge, saj pri razponu od 80 do 150 obratov v minuti ne moremo ugotoviti kakršne koli povezanosti z uspešnostjo metov.Source: Šport : revija za teoretična in praktična vprašanja športa. - ISSN 0353-7455 (Letn. 62, št. 3/4, 2014, str. 134-140)Type of material - article, component part ; adult, seriousPublish date - 2014Language - slovenianCOBISS.SI-ID - 4608177
