CHARACTERISTICS OF FEMALE VESTIBULO-AUTONOMIC STABILITY IN DIFFERENT PHASES OF THE MENSTRUAL CYCLE IN THE ASPECT OF PILOTED SPACE MISSIONS
The goal was to analyze retrospectively the data about tolerance of experimental motion sickness (MS) by 15 normal female subjects (25 to 37 y.o., mean age 31 ± 6 yrs.) in different phases of the menstrual cycle. Motion sickness was modeled by continuous cumulative Coriolis (precession) accelerations on menses days 1-2 and in 7-10 days after menses. The analysis revealed a tendency for vestibular tolerance detriment in several females during the menstrual cycle. Probability of the detriment of vestibular-autonomic tolerance because of the menses should be taken into account in the medical support system of mixed crews to the ISS and future exploration missions to the Moon and Mars.
