METHOD FOR ASSESSING MOTOR ACTIONS OF AN ATHLETE IN BADMINTON Russian patent published in 2019 - IPC A63B71/00 G06F3/33 

FIELD: sports.

SUBSTANCE: invention refers to physical culture and sports and is intended for assessment of sportsman's actions in badminton, detection of perspective sportsmen at the initial stage of training and improvement of data of professional sportsmen. In order to design a shuttle fall path, two chambers are installed, which are located at the side at the level of flounces and together with the game center. Together with changing the position of the game center, a game court and a player are photographed, the video image is transmitted to a computer, where motion capture is used to determine movement speed of the shuttle, for further use of said information for designing a trajectory. Light spot is created in the PS on the surface of court 1 for playing badminton with a light emitter placed at a given height above the court surface, which is controlled by a computer. In preset game zones 4–11 at preset height contact devices are arranged, in center of court near grid 2 at specified height board 3 with indicators is displayed, it displays court with game zones, contact devices in game zones, scoreboard 3 with indicators and cameras are connected to computer .Computer is used to set a sequence of movements of the sportsman from the PS to the preset game zones and the delay time of the movement signal to the game zone from the time of the sportsman's return to the PS. Direction of movement towards the playing area is set by signaling to corresponding display 3 indicator. Horizontal projection of court with game center and sportsman is removed with video camera located together with light emitter, as well as vertical projection is transmitted to computer. Sportsman moves from the game center to the specified game zone, closes contacting by racket or hand corresponding contact device and returns to PS. Video from each camera is transmitted to a work station, where by decomposition into frames, the shuttle speed is calculated, and then, according to known data, an approximate point of the shuttle fall is calculated [3]. In implementing the disclosed method, known engineering solutions and apparatus can be used, for computer processing of obtained information can be used known or original software. Proposed method for calculating the shuttle fall trajectory allows determining the approximate point of the shuttle's impact after the athlete's racket hits him with due allowance for the initial velocity and direction of the impact. Based on the obtained data, prospective children can be selected for badminton classes, individual training of motor actions of badminton players. Thus, the proposed method for evaluating motor actions in badminton has new properties that make it possible to obtain a positive effect.

EFFECT: development of a method for trajectory of impact on shuttle and its further falling for improvement of training process and construction of individual plan of trainings of players in badminton.
