THE EFFECT OF SHOOTING RANGE ON THE DYNAMICS OF LIMBS ANGULAR VELOCITIES OF THE BASKETBALL SHOT

Abstract

The aim of our research was to describe the joint angular velocities of young basketball players (U16)
during their performance of jump shots and to find out what was the effect of increasing shooting range on
these velocities. Our sample included 14 players that performed the function of guards. Their average age
(±SD) was 15.43±0.51 years. The analysis contemplated 370 field goals, which were performed from three
different distances (3.75 m, 5.25 m and 6.75 m) perpendicular to the hoop board. The measurements were
performed using an Xsens MVN inertial suit. The results showed that the maximum angular velocity in the
shoulder and elbow joint became greater with the increase of shooting range. In the throw from the shortest
distance, the segments were integrated into the movement of the shooting arm according to the proximaldistal
principle. The temporal sequences of maxima velocities in legs were preserved in throws from all the
three distances. The findings are important for young basketball players and their coaches. They have to be
aware of the needed adjustments to the techniques of throws from various ranges and they must take them
into account when practicing.
