The purpose of the work is to experimentally substantiate the development methodology of special physical and technical preparedness of female basketball players aged 13-14. Material and methods. Basketball players of Sports School №13 (age 13-14 years) took part in the experiment: experimental group (n = 18); control group (n = 18). The experiment was conducted in August 2018 for three months. Before and after the experiment, basketball players were tested for physical fitness (running 6 meters, shuttle running 2x28 meters, flexing their arms in the resting position, jumping rope), technical readiness (speed of defensive movements, throws from different distances, speed ball). To determine the psychophysiological state of the athletes of the experiment, psychophysiological indicators were recorded using the “Psychodiagnostics” computer program (the speed of a simple and complex reaction in various testing modes). To determine the speed of the motor hand was used the test "shifting chips." Results. A method of developing special physical and technical preparedness of basketball players has been developed and introduced into the training process of young basketball players. The technique includes doing exercises with a rubber band, exercises using unstable platforms, and running from non-standard starting positions. Revealed a significant (p<0.05) improvement of indicators in tests: the speed of defensive movements, shuttle run, high-speed ball dribble, throws from different distances of athletes from the experimental group compared to the control group. It was established a significant (p <0.05) difference in performance after conducting the experiment in tests: the speed of a simple and complex reaction and the motility of the hands of the athletes of the experimental group compared to the athletes of the control group. Conclusions. The positive effect of the experimental method on the level of physical, technical preparedness and psycho-physiological state of female basketball players aged 13-14 years is shown.
