Summary:
Jump shooting can be considered as one of the most important skills of individual technique in basketball. In particular, the three-point shot is now one of the key elements of the modern game. The purpose of this study was to determine and evaluate the kinematic parameters during the execution of three-point shots in basketball players. Specifically, the following were evaluated: a) the shot arc of the ball and its effect on the made attempts and, b) the measurement of the shot’s speed release, as well as the analysis of possible differences in specific kinematic parameters between athletes, depending on their playing position. Thus, twenty two (22) men - athletes (age 16 years ± 0.77), from development teams of A and B category U18 and U16 of the Attica Basketball Clubs Association (ESKA), participated in the research. Of these, 9 were guards, 7 forwards and 6 centers. The 94Fifty Smart Basketball Sensor was used to measure the kinematic parameters of the shots. During the measurement, each examinee performed a total of 25 spot up shots and 25 pull up shots, from the 5 positions outside the three-point line (from both angles, from both sides of 45° and from the top). From the analysis of the results, differences were recorded between the athletes that were measured, with the guards having the highest levels of shot arc of the ball compared to the other athletes, with an overall average of 44.5° SD ± 1.09° (compared to 43, 2° SD ± 0.74° for forwards and 41° SD ± 0.85° for centers). The guards, however, recorded the least stability between the efforts. At the same time, the forwards showed greater accuracy with a percentage of 33.14% (compared to 28.33% of the centers and 28.22% of the guards), while the guards released the ball faster than their teammates, with an overall average of 0, 84΄΄ SD± 0,06΄΄ (compared to 0,87΄΄ SD ± 0,03΄΄ for forwards and 0,98΄΄ SD ± 0,25΄΄ for centers). As it turns out, all the examinees had a high technical level, since the results of the research were within the ideal range set - with some exceptions - proving that the addition of technology to the training cycle can be very useful in developing and improving individual technique of basketball players.
