DEVICE FOR TRAINING AND DETERMINATION OF WEIGHT MOVEMENT TRAJECTORY AND BIOMECHANICAL CHARACTERISTICS OF WEIGHTLIFTER'S MOTOR ACTIONS Russian patent published in 2010 - IPC A63B21/62 A63B21/78 

FIELD: medicine, sport.

SUBSTANCE: device for training and determination of weight movement trajectory and biomechanical characteristics of weightlifter's motor actions contains tensometric platform, unit of variable resistance, measuring unit, including tensometric platform, force sensor, goniometre and three analogue-digital converters, personal computer, wire-and-pulley system. It contains stage, weight, spring tip with fixed optic "mouse" at its end, which is put on end of weight neck end, board, on which optic "mouse" slides, connected to USB-port of computer system unit. Tensometric platform, goniometre and force sensor are switched to internal bus of computer system unit. In unit of variable risistance two traction wires of wire-and-pulley system are fastened each opposite beginning of landing bush for load disks of weight neck. Into stage introduced are two small pulleys, rounded by said traction wires each, which are fastened to bush from both sides of weight neck, one- directly, the other, via force sensor, which is connected with its information outlet via analog-digital converter to internal bus of computer system unit. Two goniometres are fastened on knee and elbow joints of weightlifter, with information outlets via analog-digital converter are also switched to internal bus of computer system unit, stage and unit of variable resistance are connected to each other via device for hauling in traction wire slack.

EFFECT: application of claimed invention allows to obtain information about weight position.
