Electrophysiological signals analysis during reproductive period.

Bioelectrical impedance analysis is one of the relatively practical, inexpensive, and noninvasive methods of body components assessment. The intent of this study is to inspect body structure and to control if there are any significant fluctuations in body composition during the reproductive period; these fluctuations can be detected with analysis of body composition by the bioelectrical impedance measurement, which is estimated using four different contact-electrodes under specific pre-testing instructions and using the Hydra 4200 Device. The study was carried out on 21 healthy women volunteers aged between (20-25) years. The whole body Wrist-Ankle measurements protocol was used, and this experiment was carried out during the reproductive period phases: menstrual, follicular, primary luteal, and late luteal. The results of this study are classified according to the stages of the reproductive period; they showed that fat-free mass, fat mass, and total water content in the body increased during the period and reached the maximum values at the late luteal phase. Also, it has been noticed that there are no big fluctuations in body composition. Contact electrodes of bioelectrical impedance analysis devices could be utilized at any time during a woman's reproductive period without altering body composition values during this time.
