Sažetak:Istraživanje je provedeno na uzorku vrhunskog bacača kugle, reprezentativca BiH, s ciljem utvrđivanja značajnosti i veličine uticaja uglovnih vrijednosti (A) segmenata tijela u projekciji (z) ose na dužinu izbačaja kugle 0.1 s prije izbačaja. Uzorak varijabli predstavljali su uglovni položaji (A) segmenata tijela snimljeni 0.1 s prije izbačaja kugle, njih dvadeset jedan, koji su činili prediktorski skup varijabli. Prilikom izbora varijabli vodilo se računa da one zadovoljavaju osnovne metrijske karakteristike (validnost, relijabilnost, objektivnost, osjetljivost) i usklađene sa tehnologijom i instrumentarijem koji je korišten prilikom snimanja i utvrđivanja njihovih kinematičkih parametara. Za utvrđivanje značajnosti i veličine uticaja kinematičkih parametara pojedinih segmenata tijela bacača kugleuglovnih (A) vrijednosti u projekciji (z) ose 0.1 s prije izbačaja kugle (prediktorski skup varijabli) na dužinu izbačaja (domet) kugle (kriterijska varijabla), primjenjena je regresiona analiza. Rezultati regresione analize ukazuju na to da postoji statistički značajan uticaj uglovnog položaja (A) segmenata tijela u projekciji (x) ose na dužinu izbačaja kugle 0.1 s prije izbačaja. Analizom uticaja pojedinačnih varijabli uglovnog položaja (A) u projekciji (z) ose, može se vidjeti da najveći i statistički značajan pozitivan uticaj na kriterijsku varijablu, dužina izbačaja u vremenu 0,1 s prije izbačaja ima varijabla, uglovni položaj lijevog ramena u nivou sedmog vratnog pršljena (AzLC7R). U trenutka izbačaja do 0.1 s prije ugaonog položaja lijevog ramena u nivou sedmog vratnog pršljena u osi (z) došlo je kao posljedica povezanosti uglovnog (A) kretanja u vertikalnom opružanju tijela ose (z) u odnosu na projekciju kretanja sprave odnosno trenutka izbačaja. When selecting variables, it was taken into account that they satisfy the basic metric characteristics (validity, relievability, objectivity, sensitivity ...) and that they are aligned with the technology and instrumentation used to capture and determine their kinematic parameters. In order to determine the magnitude and size of the infl uence of kinematic parameters of the individual shot put elements (A) in the projection (Z) or 0.1 s before the ball spout (predictor set of variables) on the length (range) of the sphere (criterion variable), regression analysis was used. The regression results of the analysis indicate that there is a statistically signifi cant infl uence of the angle position (A) of the body segments in the projection (X) or the length of the sphere 0.1 s before the throw-out. Analysis of the infl uence of individual variables of the angular position (A) in the axis (Z), shows that the most statistically positive impact on the criterion variable length in the ejection time of 0.1 seconds before ejection has a variable angular position of the left shoulder of the level of the seventh cervical vertebra ( AzLC7R). The time span up to 0.1 seconds before the angular position of the left shoulder to the level of the seventh cervical vertebra to the...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
