[Modelling the wave movement of a multisegment biomechanical system].
Modeling of wave motion of human body's multi-segment biomechanical system by examination of forced transverse oscillations of one-dimensional bar system with distributed parameters is performed in javelin throwing. Energy flow value under different changes of model parameters is investigated. The experimental data showing wave front motion and transformation of spectral density of oscillations from segment to segment of the thrower's body are discussed. Share of the energy transferred along the body's segments in the total energy of javelin release is 70-72 per cent according to theoretical estimates for concrete model parameters, and 63-75 per cent according to the experimental data for 8 attempts.
