Sažetak
The main objective of this study was to establish
whether fatigue has an effect on accuracy during
basketball shooting. Aside from basketball shooting
accuracy, two very important kinematic parameters were
also examined as they have an effect on the level of
accuracy during shooting: the speed of performing the
actual shot and the angle at which the ball enters into the
basket after a jump shot is performed.
In conducting this research one examinee was
observed, a member of the Croatian U16 National
Basketball Team. This research included a precisely
defined protocol according to which the following
parameters were established: the accuracy of basketball
shooting (ratio between successful and missed shots), the
speed of performing the shot and the angle of entry of the
ball into the basket. The physiological load was
determined by performing the standardised specific
protocol which the examinee performed until exhaustion.
The results which were obtained indicate that there
are no significant changes in the accuracy during one
point, two point or three point shooting under the
influence of physical fatigue. The obtained results of
kinematic parameters indicate that there are statistically
significant differences in the shooting speed before and
after loading in two point and three point shots. During
performing free throws the angle of entry of the ball into
the basket changes, whereas the accuracy remains
unchanged.
