The study of the dynamic characteristics of an athlete's muscular system

The paper considers a new pattern, revealed during the biomechanical analysis of the purposeful movement of an athlete, linking the control moment of the muscular system with the speed of its change. It is shown that in different phases of a sports exercise, these dynamic characteristics reach extreme values. At the same time, the observed extremes of moments and their dynamic velocities always go in pairs, usually having a time interval between them in fractions of a second, rarely more. The analysis of the nature of changes in the values of control moments and their dynamic speeds at the experimental and theoretical levels showed: firstly, the presence of such a pattern in different sports, and in different exercises, for example, in gymnastics and weightlifting; secondly, the analysis presented the complex nature of the influence of various power factors on the displacement of the peaks of the values of the control moment and the speed of its change, as the sum of such influences on the overall result.
