Influence of kinematic parameters on Shooting efficiency in basketball

Preciznost je motorička sposobnost koja uz ostale kvalitativne i kvantitativne motoričke sposobnosti značajno utječe na postizanje uspjeha u košarci. Cilj ovog istraživanja je bio utvrditi da li određeni kinematički parametri utječu na preciznost skok šuta u košarci. Istraživanje je provedeno na uzroku od 17 kadeta Hrvatske reprezentacije (U16) visine 193,39 ± 8,13 centimetara, mase 82,56 ± 11,51 kilograma, te 16,23 ± 2,42 % masnog tkiva. Varijable promatrane u ovom istraživanju bile su bilježene uz pomoć Xsens Awinda kinematičkog sustava, na način da su se mjerile maksimalna visina izbačaja zgloba šake u trenutku izbačaja lopte, kut u ramenom zglobu u trenutku izbačaja lopte, kut pada lopte, oscilacije centra težišta po x osi tijekom šuta, visina odraza tijekom skok šuta, opći centar težišta tijela pri prijemu lopte, te trajanje šuta. Rezultati su pokazali kako promatrani kinematički parametri nemaju statistički značajan utjecaj na efikasnost šutiranja (p>0,05) kod kadeta Hrvatske reprezentacije.Accuracy is motoric ability that, in addition to other qualitative and quantitative motoric abilities, significantly influences the achievement of basketball success. The purpose of this study was to establish whether certain kinematic parameters affect the accuracy of the jump shot in basketball. The study was conducted on the sample of 17 cadets of the Croatian National Team (U16) 193,39 ± 8,13 centimeters in height, 82,56 ± 11,51 kilograms in weight, and 16,23 ± 2,42 % of adipose tissue. The variables observed in this study were recorded by the Xsens Awinda kinematic system, in a way that it was measured the maximal height of ejection wrist joint at the moment of ball releasing, shoulder angle at the moment of ball releasing, oscillations of the center of gravity of the body along the x axis during the shot, height of reflection during the jump shot, the general center of gravity of the body when receiving the ball, and the shot duration. The results showed that observed kinematic parameters don’t have significant influence on the jump shot efficiency (p>0,05) of the Croatian National Team cadets
