Abstract

The paper compares the degrees of postural stability reduction in healthy subjects (n = 111) as a result of two disturbing actions: during maximal voluntary hyperventilation and immediately after submaximal bicycle exercise. Vertical posture stability was investigated using stabilography. We found that both disturbing actions significantly increase the variance of fluctuations in the frontal and sagittal planes, the area of fluctuations as well as the mean linear velocity of center of pressure fluctuations. Medium strength correlations were established between stabilographic and ventilation parameters. The degree of reduction of postural stability was higher during maximal hyperventilation than after submaximal exercise. Thus, the effect of maximal hyperventilation on vertical posture stability is greater than the effect of submaximal exercise.
