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 is the effect of increasing shooting range on these velocities. Our sample included 14 players that performing 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.

The Jump Shot Performance in Youth Basketball: A Systematic Review

“…Twelve documents were selected for this analysis ( Table 1 ). Evidence was synthesized according to the following variables: (i) distance variation to the basket (four studies) [ 16 , 19 , 20 , 21 ]; (ii) fatigue (four studies) [ 15 , 22 , 23 , 24 ]; (iii) presence of a defender (two studies) [ 9 , 25 ]; (iv) visual information available (two studies) [ 12 , 26 ]. One of the documents has reported data on the JS performance both on a defender’s presence and on the players’ gaze behavior (visual information) [ 25 ].…”

“…In a three-dimensional kinematic analysis, the joints’ angular velocities were assessed during the JS performance in a group of 14 top-level male players aged 15.4 ± 0.5 years [ 16 ]. The authors aimed to describe the joint angular velocities during the JS performed three distances to the basket (3.75, 5.75 and 6.75 m).…”

“…The angular velocity of the elbow and the shoulder joint at ball release was also higher at longer shooting distances. On the contrary, no significant differences were reported on the wrist joint’s maximum angular velocities, with mean values of 1528 ± 383.2°/s at 3.75 m and 1731 ± 658.5°/s at 6.75 m [ 16 ].…”

“…The ball trajectory, defined by the angle, velocity and height at the moment of ball release [ 8 ], intermediates the players’ muscle action and the final outcome. Additionally, parameters of the shooter have also been studied, such as the position of the center of mass (CoM) [ 7 , 13 , 15 ]; trunk inclination [ 7 , 13 ]; jumping flight time [ 2 , 7 , 9 , 16 ]; changes in landmarks placed at joints to assess the respective position and time variations [ 10 , 11 , 16 ]. The kinematic parameters have been previously used to evaluate the game-related conditions as a source of inter and intra-individual variability among basketball shooters [ 7 , 8 , 10 , 11 , 14 , 17 ].…”

“…Modern concepts in the theory and method of sports training on the development of jumping are reduced to the fact that the use of exercises mainly of a jump character contributes to improving only the speed of repulsion, and the use of exercises power and speed-force character provides growth and speed, and the forces of repulsion. It should be considered proven position on the necessity of the predominant development of speed-strength properties of the muscles, in combination with exercises to increase mobility in the joints and relaxation in order to develop jerking and inter-muscular coordination (Padulo, Nikolaidis, Cular, Dello Iacono, Vando, Galasso, Ardigo, 2018, Podmenik, Supej, Coh, & Erculj, 2017Pojskic, Sisic, Separovic, & Sekulic, 2018). An open question remains about the qualitative parameters of the training effects of power and speed-force orientation, which ensure the development and support of the achieved level of jumping.…”
