Influence of the visual feedback for some parameters of the body oscillations on their stability.

In accordance with the hypothesis that in addition to the generalized information from the visual feedback about the body oscillations, the information from the different parameters of the oscillations may also play a stabilizing role for the vertical posture of the body and its balance, studies were carried out on the influence of the parameters of body position, velocity of the body oscillations and accelerations on body stability. The results have shown that the visual feedback about the position of the body and about the velocity of the oscillations leads to stabilization of its balance. Visual feedback about the accelerations of the body oscillations also has a stabilizing action on the vertical posture and equilibrium. Its influence did not prove greater than the visual feedback about the velocity of body oscillations. Repeated recordings of the body oscillations under the experimental conditions manifested a slight initial training effect, expressed in a decrease of the total way of the body oscillations.
