The study objective is to develop a methodology for determining the jump height and jumping endurance in basketball players of various gaming functions using modern nanotechnology and microprocessor systems, in particular smartphones, personal computers, etc. Materials and methods. The study used a method for determining jump height and jumping endurance using capacitive sensor devices based on a combination of modern nanotechnology and microprocessor systems, in particular smartphones, personal computers. Results. The study showed that the use of modern nanotechnology to monitor the jump height and jumping endurance allows you to study these indicators with high accuracy, which is very important in scientific research. The study showed that the absolute height of the jump in center players is 328.1 ± 7.88 cm, in attackers – 324.1 ± 6.62 cm, in defenders – 314.4 ± 8.65 cm. The relative height of the jump in defenders is 57.7 ± 6.86 cm, which is on average 8.2 cm more than in center players, and 5.3 cm more than in attackers (p < 0.001 and p < 0.02, respectively). Conclusions. The use of modern nanotechnology and microprocessor systems to determine the parameters of jump height and jumping endurance allows you to determine these parameters with high accuracy. The use of modern, accurate nanotechnology measurement and calculation of jump height and jumping endurance indicators using graphic data analysis provided a complete description and degree of development of various “jumping” qualities of basketball players. Studies have shown that the jump height and jumping endurance in basketball players of different roles (defenders, attackers, and center) differ with a high degree of reliability.
The study purpose was to determine the technical-and-tactical indicators of young basketball players aged 13-14 in the process of competitions and to develop recommendations for assessing the competitive activities of young basketball players. Materials and methods. The study used the method of pedagogical observations during competitions with recording in a specially developed protocol the following indicators of competitive activity of young basketball players: throws to the basket in motion, two- and three-point throws, free throws, quick breakthrough, positional attack, struggle for rebounding the ball, interception of the ball, “goal assists”, technical errors, and other losses of the ball. Results. As shown by the results of studies of such a technical indicator as throwing the ball into the basket in motion, young basketball players aged 13-14 have the highest accuracy in hitting the basket in this technique of the game – 49.1%. Moreover, the hit percentage (51.6) is higher in the first half of the game than in the second half (46.6) with a high significance level of the difference (p>0.99). A similar situation is observed when making two- and three-point shots from the distance. Studies of the effectiveness of free throws have shown that, on average, basketball players aged 13-14 make 14.1 free throws, of which 7.1 hit, which is 52.2 %. Studies have shown that the number of quick breakouts averages 8.45 per game (5.18 in the first half and 3.27 in the second half). The number of possessions of the ball in the fight for the rebound on own backboard is 14.9 times, and on the opponent's backboard – 13.36. The average number of “goal assists” per game is 4.36, ball interceptions – 8.18, technical errors – 15, and other ball losses – 9.54. Conclusions. Studies of technical-and-tactical indicators of young basketball players during competitions have shown that their role is underestimated in the practice of training young basketball players. The training programs for basic training groups (aged 13-14) shall include in full all technical-and-tactical indicators, and especially throws in motion from under the backboard, two- and three-point shots, “goal assists”, free throws, ball losses, interceptions, block shots, struggle for rebound, indicators in a quick breakthrough and in a positional attack, the number of points conceded, etc. It should be noted that there is a higher number of technical-and-tactical indicators in the first half of the game, compared to the second half, with a high significance level of the difference between the indicators. This indicates the growing fatigue of young basketball players and the need to find ways to improve the system of training speed endurance and throwing techniques in a state of fatigue.
