Abstract

Aim. The study deals with the assessment of the effect of biological feedback with various parameters on controlling vertical position in human. This is necessary to justify physiologically the choice of an adequate control regime. Materials and methods. 25 apparently healthy volunteers aged 18–35 participated in the study. These volunteers are not professional athletes. The main method is the assessment of biocontrol parameters using the ground reaction data obtained with a force plate. Results. We revealed that an increase in feedback depth during the biocontrol assessed using the ground reaction data obtained with the force plate with a visual channel decreases the efficiency of vertical position targeted control. Moreover, we defined the extreme range of an increase in the coefficient of transformation of the physiological signal (sensitivity). This was done to obtain the coordinates of the common center of pressure on the ground, which preserves the ability of targeted control in untrained volunteers and equals approximately 50–70 % of standard values. Conclusion. Changes in the depth of biological feedback is a key factor, which influences the efficiency of procedures with biological feedback.
