indent Abstract
With the help of the 94Fifty technology we were able to analyze the three-point shot. We were curious to know whether the majority of the shots are recommended by the manufacturer of the measuring system and carried out in preplanned intervals of entry angles, the rotation of the ball, and the release time of the ball, and we wished to find out the consistency of the aforementioned parameters between the guards and other players. The hypotheses were tested on a sample of 52 great male basketball players, aged 18 and 19. We deducted that most of the shots from the distance of 6.75 m occur under a entry angle greater than 42°, but not in the estimated interval (between 42° and 48°); that most of the shots do not occur in the estimated interval of the rotation of the ball (from 130 to 150 revolutions/minute); and that most of the shots do not occur in the estimated interval of the release time (< 0.7 seconds). When it comes to the consistency of the before mentioned parameters we did not find any discrepancies between the guards and other players. Based on the results a question arises: did the manufacturer of the measuring system adequately form the intervals of the aforementioned parameters or does the problem lie in the performance of the shots by the chosen players?
