Аннотация: The approaches to determining the horizontal coordinates of the center of mass (CoM) applicablefor force plate, for which only vertical forces are the measurements, are compared. Thefirst of these approaches uses the information not only about the initial position and rate of CoM, but also about its terminal state. The second is associated with the use of the assumption about the absence of unstable components in the movement and uses frequency filtering methods. Known algorithms were modified to solve the problem in conditions of sufficiently intense movements by a person. The considered modified algorithmswere compared for recordings movement of the subjects who performed a test with a stepwise disturbance on a force plate. A system of video cameras was simultaneously used to determine the coordinates of a marker fixed approximately at the CoM height. The working capacity of all modified algorithms was demonstrated. It was noted that the error of the estimation method using a double filtration in forward and reverse time was lower than in other procedures.Reeding full text: https://rdcu.be/cDPVb
