[Influence of semantic stress on the motor program structure].

To approach the applied aspects of support to operator interacting with the aerospace technical systems, the authors are working on the problems of structuring the motor programs and deformation caused to them by semantic stressful agents. Possibility for varying the composition of locomotion programs to ensure success of a general motor task had been experimentally demonstrated. Data obtained are viewed from the standpoint of revision of the motor image in the psychic control system.

[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.

[A model of the biological oscillator as the basis for the coordination of motor activity].

System mechanisms, that underlied motor activity coordinations were investigated on the model of biological oscillator. It has been shown how the value of phase resettings induced by single stimuli sequences depends on the stimulation location in the cycle. The time of reaction to the stimulus has been determined as the function of stimulus location. In addition, the character of transitional process, after which the parameters of initial rhythmic activity completely become normal, has been determined. The data obtained have been interpreted for the model of temporal motor control, which was suggested by A. Wing and A. Kristofferson.
