FIELD: sports.
SUBSTANCE: invention relates to the field of sports and sports medicine, can be used by doctors in the sports medicine and exercise therapy, by coaches for operative control of biomechanical and electromyographic parameters of weightlifters during snatch or jerk weightlifting exercises, in particular, for evaluating the technical and physical fitness thereof in the preparatory and competitive periods of the training process. The technical result is achieved by providing a possibility of high-precision synchronous recording and processing of the kinematic, dynamic, electromyographic, and video data for analysing and monitoring the technical and physical fitness of weightlifters during weightlifting exercises. The new features of the invention therein are that: infrared illumination of markers is used, invisible to the human eye; high-speed synchronous video recording is conducted from three infrared cameras of the SMART system; passive infrared markers are used, attached to the body of the weightlifter and to the two ends of the bar of the barbell; angles, angular velocities in the hip, knee, ankle joints are calculated using three-dimensional coordinates of the markers; using the synchronised data on the coordinates of the barbell, the angles in the knee joint, the reaction forces of the right and left supports, as well as the bilateral video recording, the weightlifting exercises are divided into time phases by an instructor operator; the coefficients of asymmetry of the reaction forces of the right and left supports are calculated for individual phases of the weightlifting exercises; the electromyographic parameters of muscle groups are determined for individual phases of the weightlifting exercises by retrieving data from 8 wireless sensors of the surface electromyography system, attached to the body of the weightlifter.
EFFECT: creation of a method for biomechanical and electromyographic evaluation of weightlifting exercises for use in the sports medicine and exercise therapy.
