Comparative Analysis of Methods for Calculating the Center of Gravity in the Task of Analyzing Human Movement

Biomechanics is a complex network of interdependencies between various biological and mechanical parameters that determine the stability of human movement in space through the position of the center of gravity of the body (CT). Determining the variability of CT is crucial in solving the problems of the human condition (as opposed to the motor norm) in medicine, in sports and other areas of human life. The center of gravity is an imaginary point that helps to analyze various configurations of the human body both in static and in motion. This article discusses various methods for calculating the center of gravity of a person passing in a sagittal projection in front of the camera, and also compares them. The results of the study may have important practical significance for various applications of human movement analysis. They can be used in sports training to optimize movement techniques, in medical rehabilitation to assess the patient's condition, as well as in the entertainment industry to create realistic computer animations. The main methods of localization of CT of the human body, which can be obtained from image analysis, are given. A comparative analysis of methods in determining human CT was also presented.
