DEVICE FOR BIOMECHANICAL CONTROL OF TECHNICAL PREPAREDNESS AND PHYSICAL FITNESS OF WEIGHTLIFTERS Russian patent published in 2018 - IPC A63B71/00 

FIELD: sports.

SUBSTANCE: invention relates to the field of sports and can be used for operative control of biomechanical parameters of weightlifters, in particular for assessing their technical preparedness and physical fitness, both in training and competition. Claimed device registers the motion of the center of mass of the rod (CM) on the basis of markers attached to both ends of the weightlifting bar. Directly on the weightlifting platform, a dynamometer platform is built, which allows using strain gauge sensors to record dynamic characteristics (the reaction force of the support, the coordinates of the pressure center), on the basis of which it is possible to calculate the kinematic characteristics of the motion of the common center of mass of the "weightlifter + barbell" system. Records of the movement of the center of mass of the barbell are recorded by bilateral (two-sided) video. Markers are made of paper and are concentric circles with a diameter of 3.5–4.0 cm, fixed on both ends of the weight bar with double-sided adhesive tape. Claimed device allows receiving urgent (operative) information on the technical preparedness of weightlifters, determine the most rational way of doing the exercise, about the errors made and their subsequent adjustment, and also to select the most promising students.

EFFECT: improving the quality of control and analysis of parameters.
