Abstract

The cardiovascular and respiratory response to motion sickness has been a field of interest for many scholars. However, in looking at their research fmdings. one notes a lack of concentration on the autonomic response. This necessitates a new approach and new tools to attain a better understanding of the autonomic effects involved in the motion sickness stimulation of the heart. That is the strategy that this research aimed for in its attempt to monitor the vagal activity in ten NASA volunteers undergoing motion stimulation. The heart rate spectrum was adopted as the technique which noninvasively allows the quantitative measurements of vagal tone by assessing the amount of heart rate variability occurring at the respiratory frequency. Power in the frequency band of the heart rate spectrum corresponding to the nominal respiration frequency has been shown to be purely vagal in origin, and we refer to this measure as vagal power. The initial hypothesis was that vagal tone would drop as a sign of increasing stress when subjects reported increasing motion sickness, as indicated by a standardized diagnostic malaise scale.
