Swinging leg influence on long jump

Abstract

The influence of swinging leg on long jump result is analyzed in the paper. For this purpose three mass link-age type model is constructed the mobility of foot joint is evaluated in which. After natural frequencies determina-tion mass centre coordinates of the separate body parts, their derivatives of the first order and the coordinates of general mass centre are expressed. The equation of kinetic moment the first order derivative in time of which is the searched driving moment is obtained.
