Abstract: Among different examination procedures, especially biotonometry, which is a biophysical measuring method for registering the hand polarization as a measure for the vegetative functional condition, is suited for the research of vegetative phenomena.The work presented, wants to find an answer to this question. In addition, we will discuss, whether biotonometric measurements make sense in the field of sports or not.25 students participated in the experiment, which consisted of three phases of rest in a lying position, exercises on an ergometer and afterwards recovery in a lying position.The parameters systolic blood pressure and heart frequency served as a control of the momentary functional condition of the vegetative nervous system. 'Me measurement of the skin resistance and the skin capacity was carried out via a biotonometer with two hand electrodes. The changes in resistance during the experiment were highly significant. During the phase of rest there was a clear increase in the skin resistance. During the exercise there was a stronger decrease and in the following phase of recovery there was a clear increase present. There was no tendency to changes in the course of the three phases with respect to the values of the skin capacity. Nevertheless, the differences between the respective beginning of the phase and the end of the phase were significant, in the phase of rest even highly significant, which is a remarkable indication of a delayed sympathetic activitiy in the periphery, i. e. in the skin.Further examinations seem to be necessary for the decision, whether biotonometric measurements are suitable for the quantification of the effects of physical exercises on the neurovegetative system.
